Executive Summary 

Washington County Regional Reuse System 

February 27, 2023 

Washington County Water Conservancy District 

St. George, Washington County, Utah 

The Washington County Regional Reuse System will help maximize local reliable water supplies 

that are under increasing pressure from climate change and economic growth. A potable and 

secondary irrigation reuse source will be integrated into Washington County’s water supply 

portfolio to help meet water demands. The Regional Reuse System will ultimately include 

multiple water treatment facilities, pipelines, and storage reservoirs to reuse approximately 

47,000 acre-feet of water each year by 2050. The Washington County Water Conservancy 

District proposes in this application to complete design data studies, preliminary design and cost 

estimating activities, baseline environmental and cultural resources studies, and initiate 

environmental compliance and permitting. The planning and preconstruction activities proposed 

in this application will start after pre-award clearances are complete and end 24 months later 

(approximately Fall 2025). The System would not involve a Federal facility, but will involve 

obtaining right-of-way on Federally-managed land.

Washington County Regional Reuse System: Planning 

Technical Proposal and Evaluation Criteria 

Project Location 

The Regional Reuse System is located in Washington County in the southwest corner of Utah. 

The Regional Reuse System will provide municipal and industrial (M&I) reuse water to portions 

of the Washington County Water Conservancy District (WCWCD) service area. The WCWCD 

service area (Figure 1) encompasses all of Washington County, Utah, but WCWCD does not 

currently provide water to all communities within the county. In 2006 (and later updated in 

2019), WCWCD adopted the Regional Water Supply Agreement (RWSA) with the following 

municipalities: 

• St. George City • Ivins City 

• Washington City • La Verkin City 

• Hurricane City • Toquerville City 

• Santa Clara City 

WCWCD acquires, constructs, and operates its water system to meet anticipated municipal 

demand, while the individual cities maintain their existing water infrastructure systems and fully 

utilize their respective municipal supplies. Reuse water supply will be delivered to RWSA 

municipalities within the WCWCD service area (Figure 1). 

Project Description 

This section describes the activities being proposed for funding under Notice of Funding 

Opportunity (NOFO) No. R23AS00076. For a brief description of the proposed Regional Reuse 

System, see the response to Question No. 3 under Subcriterion No. 1b. 

APPLICANT CATEGORY 

WCWCD is seeking funding for Funding Group II. 

ELIGIBILITY OF APPLICANT 

WCWCD is a political subdivision of the state of Utah. WCWCD is charged with conserving, 

developing, managing, and stabilizing water supplies within Washington County in an ongoing 

effort to provide a safe, sustainable water supply for current and future generations. WCWCD 

has the powers conferred to local districts by Utah Code Annotated § 17B-1-101 et seq. and to 

water conservancy districts by Utah Code Annotated § 17B-2a-1001 et seq.

Washington County Regional Reuse System: Planning 

Technical Proposal and Evaluation Criteria 

GOALS 

WCWCD proposes in this application to complete planning and pre-construction activities for a 

Regional Reuse System. The ultimate goal is to integrate a potable and secondary irrigation reuse 

source into Washington County’s water supply portfolio to help meet water demand for the 

area’s expanding economy and growing population through 2070 and beyond. Specific activities 

proposed in this application are as follows: 

• Complete site-specific geotechnical and survey studies to gather design data 

• Refine preliminary project designs and cost estimates 

• Initiate environmental compliance and other related permitting activities 

• Compile and/or complete baseline environmental and cultural resources studies 

The development of a large-scale reuse feasibility study meeting the requirements of WTR 11-10 

and WTR TRMR-128 is not proposed as an activity under this application. WCWCD is currently 

developing such a feasibility study for the Regional Reuse System under Funding Group II and 

intends to submit the study to the U.S. Bureau of Reclamation (Reclamation) for review and 

approval in Spring 2023. Costs to develop this project’s feasibility study cannot be considered 

for reimbursement under this Notice of Funding Opportunity (NOFO) because those costs will 

be incurred prior to notification of selection. 

APPROACH 

The Regional Reuse System comprises multiple phases of treatment, conveyance, and storage 

projects, as described in Question No. 3 under Subcriterion No. 1b. The Regional Reuse System 

will implement potable reuse and supplement secondary irrigation systems to allow secondary 

water supplies to meet potable demands. 

Phase 1 treatment and conveyance reuse projects include the following: 

• Existing St. George Reuse Facility • Pipelines from SGRF to AWT 

(SGRF) upgrade to 14 MGD forebay and existing Ivins Reservoir 

• SGRF onsite reuse pond for • Pipeline from AWT forebay to New 

treatment operations (100 acre-feet) System Storage 

• Ash Creek Special Service District • Pipeline from existing Confluence 

(ACSSD) mechanical Type 1 reuse Park Water Reclamation Facility to 

treatment facility Toquerville Secondary Water 

System (TSWS) • Advanced water treatment (AWT) 

facility (21 MGD) 

The activities and approach proposed under this NOFO are to complete the following planning 

and pre-construction studies for Phase 1 treatment and conveyance projects during the 24 months 

Technical Proposal-4 
 

 

 

 

 

 

 

 

 

Washington County Regional Reuse System: Planning 

Technical Proposal and Evaluation Criteria 

after notification of award. Planning and pre-construction studies for Phase 1 reuse storage 

facilities have already been completed and are not proposed activities in this application. 

Design Data Studies 

Site-specific design data investigations for the Regional Reuse System include topographic 

surveys, geotechnical evaluations, and the development of facility planning reports. Topographic 

surveys will establish property and/or needed easement boundaries, refine facility layouts and 

pipeline alignments, and evaluate site civil conditions. Survey information will be used to refine 

pipeline profiles or hydraulic profiles for storage or treatment facilities. Geotechnical site 

evaluations will include investigated borings and soil assessments along proposed pipeline 

alignments and below treatment or storage facilities to refine pipeline excavation and bedding 

quantities, and site foundation design. The State of Utah Department of Environmental Quality 

requires a facility planning report for any new water or wastewater treatment infrastructure. This 

report will provide a summary of objectives, design criteria and conditions, alternative 

development and costs, a recommended preferred alternative, and a discussion of how this 

alternative will meet State requirements. 

Preliminary Designs and Cost Estimates 

This proposed activity will bring feasibility-level designs and cost estimates for Phase 1 

treatment and conveyance projects to a pre-final design level (Class 3 or up to a 30% design 

level). 

Environmental Compliance/Permitting 

Environmental compliance for the Phase 1 treatment and conveyance projects will be initiated, 

and may include NEPA, Section 404 permits, Section 7 consultation, Section 106 consultation, 

and water quality permits. The extent and duration of environmental compliance and permitting 

will depend on the type and number of alternatives, and potential impacts. The needs analysis 

and alternatives formulation will be informed by the approved Regional Reuse System 

Feasibility Study. After notification of award, WCWCD will work with Reclamation to develop 

work plans and schedules to complete environmental compliance activities for Phase 1 projects. 

Early and regular engagement with Reclamation and other agencies will achieve common 

understanding and agreement on several key issues such as impacts analytical methods and 

significance criteria. 

Baseline Environmental and Cultural Resources Studies 

WCWCD will determine the applicability of available information and identify data gaps. 

Through this review, existing project data may be validated or found to be invalid, inaccurate, 

incomplete, or outdated. This approach will identify the data needs for the highest priority 

resource issues. WCWCD will coordinate with Reclamation and other agencies in reviewing 

existing project-specific data. It is anticipated that biological and cultural desktop and field 

surveys for Phase 1 projects will be identified as a high priority data gap. Costs to complete these 

surveys are explicitly proposed in this application. Costs to fill data gaps for other resource areas 

are implicit in costs proposed in this application to complete NEPA compliance.

EVALUATION CRITERION 1—PROJECT PLANNING AND ANALYSIS 

Subcriterion No. 1a—Water Recycling Needs and Opportunities 

1) Describe the problems and needs in the project area. 

The Virgin River begins in southwestern Utah and ends in Lake Mead. Similar to other desert 

rivers, the Virgin River is characterized by large flow fluctuations (0 to 20,000 cubic feet per 

second or cfs) and high salinity, temperature, and turbidity. Streamflow is generally highest 

during spring runoff and large summer flash flood events. Summertime base flows are typically 

much lower and can be extremely low during dry years. 

The Virgin River Basin is the only source of water supply for most of Washington County and is 

reaching its full developmental capacity. The primary municipal diversion is at the Quail Creek 

Diversion Dam (Figure 2), which pipes water to the Sand Hollow and Quail Creek off-stream 

reservoirs. Existing and future diversions from the Virgin River are constrained by the following: 

• The Virgin River is a flashy desert stream and high flow events can fill the channel with 

sediment and debris. Under these conditions, WCWCD often shuts down the Quail Creek 

Diversion Dam to protect infrastructure. An on-stream reservoir could capture more high 

flows on river, but such a project is infeasible because of the presence of designated 

critical habitat and proximity to existing communities and Zion National Park (Figure 2). 

• The naturally occurring La Verkin hot springs (Figure 2) discharges 10-12 cfs of water 

with approximately 10,000 milligrams per liter (mg/L) of salt into the Virgin River1,2, 

thus rendering all downstream water unsuitable for potable use. Agricultural diversions 

downstream from the hot springs at the Washington Fields Diversion have a salt 

concentration of approximately 2,000 mg/L. 

• Agricultural water at the Washington Fields Diversion cannot be diverted at the Quail 

Creek Diversion Dam for potable use (thereby avoiding the hot springs contamination) 

because of the designated critical habitat for listed fish species between the Washington 

Field Diversion and diversion dam (Figure 2). It is anticipated that the U.S. Fish and 

Wildlife service would not permit further diversions upstream from this habitat. 

• Virgin River streamflow is projected to decrease under hotter, drier climate conditions3

, 

which will decrease local supply. Figure 3 shows streamflow under baseline conditions 

(1950-1999), recent conditions (2000-2020), a median future climate (50th percentile), 

and a hotter, drier future climate (10th percentile). Recent streamflow is already trending 

between the projected median and hotter, drier climate in several months.

2) Describe the current and projected water supplies and demands in the project area; include 

a discussion on supply and demand imbalances. 

Water Supply 

Washington County water supplies include supply owned by WCWCD and the local 

municipalities (Table 1). The municipalities are required to fully utilize their own sources and 

WCWCD is responsible for developing new sources of reliable water to meet the growing 

demands of the county. 

Water Demands 

To help ensure that water providers can meet water demands, the State of Utah requires water 

systems to establish a “source sizing standard” to determine the volume of water that needs to be 

available to users (Utah Code Section 19-4-114). The source sizing standard is typically 

evaluated in terms of source capacity needed per “Equivalent Residential Connection” (ERC). 

The ERC is a water planning metric that represents the water use for a typical single family 

residential connection. Upon determining the amount of water used by a typical home, the water 

use of other user types (multi-family, commercial, institutional, industrial, etc.) can be converted 

into an equivalent number of single-family residences, providing a streamlined method of 

accounting for water users within a system. 

Table 2 provides the projected M&I water supply needs for the WCWCD service area. The 

demand projections include two key assumptions: 

Technical Proposal-8 
Washington County Regional Reuse System: Planning 

Technical Proposal and Evaluation Criteria 

1. WCWCD has a conservation goal to reduce water use per ERC to 0.59 acre-feet/year 

(approximately 24%) by the year 2070, which is reflected in the demand projections. 

2. Many cities have plans to expand their secondary irrigation systems. The secondary 

irrigation water needs in the table are based on each individual city’s respective plans for 

secondary irrigation water. As these plans are implemented, a portion of potable demand 

is shifted to secondary irrigation demand.

Supply and Demand Imbalances 

Figure 4 compares projected water needs for areas served by WCWCD under a high population 

growth and hotter, drier climate scenario. Without climate change, the gross volume of municipal 

supply in the WCWCD service area would grow as new municipalities and their supply 

portfolios are accounted for. At the same time, municipal supply is predominately groundwater 

and is expected to decline under a hotter, drier climate change due to reduced precipitation and 

streamflow recharge. These two factors create a flat net municipal supply volume over time in 

Figure 4. The existing and planned WCWCD potable supplies, which are predominately surface 

water, are projected to decrease under hotter, drier climate change. As the climate becomes 

hotter and drier, the WCWCD service area demand will exceed supply after 2030.

3) Describe how the planning activities will investigate potential uses and markets. 

The primary reuse market is the municipal and industrial sector. Reclaimed water can be treated 

to Type 1 effluent standards for secondary irrigation use (per Utah Administrative Code, R317-1-

4), or to potable standards for the uses outlined in Table 3. For secondary irrigation uses, the 

following markets will be evaluated: 

• Communities currently using secondary irrigation water 

• Cities with a dry secondary irrigation system already in place 

• Cities near an existing secondary irrigation system or potential source of secondary 

irrigation/reuse water. 

Expected utilization of secondary irrigation water by 2070 is about 58,000 acre-feet per year. 

Increasing secondary irrigation supply with reuse water frees up other supplies for potable use. 

Technical Proposal-10

Technical Proposal and Evaluation Criteria 

The State of Utah does not have regulations to implement direct or indirect potable reuse. 

WCWCD and other stakeholders will work with the State of Utah on implementing regulations 

and guidance for indirect and direct potable reuse. Expected potable water demands by 2070 is 

about 117,000 acre-feet per year.

Subcriterion No. 1b— Evaluation of Project Alternatives 

1) Describe the objectives that all alternatives will be designed to meet. What other water supply 

alternatives and project alternatives will be investigated? 

The proposed reuse system and other water supply alternative must achieve the following 

prudent planning objectives, consistent with WCWCD’s mission: 

Technical Proposal-11 
 

 

 

 

 

 

 

 

 

 

Washington County Regional Reuse System: Planning 

Technical Proposal and Evaluation Criteria 

1) Securing long-term water resource reliability considering climate variability; 

2) Diversifying the region’s water sources and delivery systems; 

3) Improving operational dependability and flexibility; and 

4) Providing drought resiliency. 

Multiple reuse strategies will be evaluated as part of this investigation (Table 5). The various 

strategies will be evaluated and screened to form initial reuse alternatives. The alternatives may 

include components of one or more strategies, including systems that meet various combinations 

of potable and secondary irrigation demand using multiple treatment technologies, plant site 

locations, conveyance alignments, and storage reservoirs. For comparison purposes, the Lake 

Powell Pipeline (LPP) will be used as a non-reuse water supply alternative in this investigation 

(see Question No. 1 under Criterion No. 2 for a description of the LPP).

2) Describe how the planning activities will develop project alternatives (water supply sources, 

reuse strategies, or treatment technologies) that have been or will be investigated. 

All water supply sources described in Table 4 will be used to formulate the reuse strategy from 

options outlined in Table 5. Criteria used to select a single or combination reuse strategy include 

overall potable and secondary supply benefit, costs, and implementation schedule. The selected 

reuse strategy will then guide the formulation (sizing and location) of conveyance features and 

advanced water treatment sites. 

The selected reuse strategy, along with treated water quality goals, will drive the selection of 

treatment technologies for advanced water treatment components. WCWCD and other 

stakeholders will work with the State of Utah to develop the appropriate rules for multi-barrier 

microbial and chemical protection. This multi-barrier protection approach will guide selection of 

an appropriate mix of technologies outline in Table 6.

WCWCD and other stakeholders are currently conducting feasibility level planning analyses to 

select the Regional Reuse System projects. At the time of this application, the selected reuse 

strategy for the Regional Reuse System includes surface water augmentation involving an AWT 

facility for potable reuse, and secondary irrigation reuse production for delivery to secondary 

supply reservoir. Phase 1 of this strategy would produce up to approximately 47,000 acre-feet 

per year by 2050 (Figure 5). This strategy would be implemented by the projects outlined in

EVALUATION CRITERION 2— STRETCHING WATER SUPPLIES 

1) Describe the potential for the project to reduce, postpone, or eliminate the development of 

new or expanded non-recycled water supplies. 

The Regional Reuse System will lessen the quantity and urgency of imported water projects, 

such as the LPP. The LPP is a planned 140-mile-pipeline to import water from the Colorado 

River to Washington County. Future hydrology on the Colorado River and agreements with the 

Basin states are uncertain, and while the LPP remains a component of WCWCD’s long-term 

water resources plan, it is recognized that the project’s timing and scope may have to change. At 

this time, development of the few remaining local projects, including reuse, offers a more 

reliable supply for WCWCD. Without the initial phases of the Regional Reuse System being 

implemented in the next 10-15 years, the county would be at risk of perpetual shortages (see 

Figure 4), and WCWCD would need to accelerate plans for the LPP. 

2) Describe the potential for the project to alleviate pressure on existing water supplies and/or 

facilities. Please describe the existing water supplies, identify the supplies and/or facilities 

that will be impacted and explain how they will be impacted by the Project, including 

quantifications where applicable. 

The Regional Reuse System will postpone pressure on existing agricultural water supplies. 

Currently, agriculture has about 44,000 acre-feet of depletion water rights in the county, but only 

Technical Proposal-15 
 

 

 

 

 

 

 

 

 

Washington County Regional Reuse System: Planning 

Technical Proposal and Evaluation Criteria 

38,890 acre-feet are considered reliable (i.e., have a 1900 or earlier priority date)4. Preliminary 

climate changes analysis by WCWCD indicates that only agricultural water rights with a priority 

date of 1890 or earlier will be reliable in the future, resulting in approximately 16,000 acre-feet. 

There is generally a State and local desire to maintain a healthy agricultural economy and 

culture5. As agricultural land in Washington County is developed, some reliable agricultural 

water supply will be converted to municipal use. If the Regional Reuse System is not built, there 

will be added pressure to convert more agricultural supplies sooner and not give the county 

adequate time to avoid or mitigate the negative environmental and socioeconomic consequences. 

3) Describe the potential for the project to make water available to address a specific concern. 

Explain the specific concern and its severity. Also explain the role of the project being 

investigated in addressing that concern and the extent to which the project will address it. 

Meet Statutory Source Sizing Standard 

The new WCWCD source sizing standard, as described in Question No. 2 under Subcriterion 

No. 1a, is 0.59 acre-feet/year per ERC. Even with this conservation-based standard, Washington 

County will not meet source sizing requirements and will have a 100,000 acre-foot deficit by 

2070 under a hotter, drier climate (see Figure 4). The Regional Reuse System will contribute 

about 47,000 acre-feet by 2050 to help meet the WCWCD total source sizing requirement. 

Reduce Groundwater Depletion 

The Virgin River Basin (Utah Division of Water Rights Area 81) is currently closed for 

additional groundwater appropriation, but to date a Groundwater Management Plan has not been 

required to repair or prevent Virgin River Basin overdraft. Groundwater and natural springs are 

the predominate potable water supply for many Washington County communities (Table 1). 

Studies have shown, however, that the average natural recharge to the local aquifer is likely 

much less than the total water rights allocated for the basin6

. The Regional Reuse System will 

support a more sustainable use of local groundwater resources. Without the project to support 

future demands, these groundwater supplies could be used more heavily and may necessitate a 

Groundwater Management Plan to manage potential future overdraft. 

Reduce Competition for Water Supplies 

The Regional Reuse System will lessen the speed of converting existing agricultural supply to 

municipal use, as described in Question No. 2 under Criterion No. 2. 

Protect Drought Resiliency 

Without the Regional Reuse System, WCWCD will need to rely more heavily upon banked 

groundwater reserves below Sand Hollow Reservoir to meet potable demands. This reserve 

supply (currently about 160,000 acre-feet) is intended to meet demands during short-term, acute

Technical Proposal and Evaluation Criteria 

drought periods. Relying on these reserves for multiple years under non-drought emergency 

conditions weakens the region’s drought resiliency. 

Mitigate Natural Disasters 

The majority of WCWCD’s surface water supply originates from the upper Virgin River 

watershed in and near Zion National Park, whereas the county’s groundwater supplies occur 

further downstream in the watershed. Both the surface water and groundwater supplies are 

subject to localized wildfire, flooding, and other infrastructure risks. Infrastructure to reuse either 

supply would diversify the supply portfolio and thereby alleviate pressure during an emergency 

outage in the watershed. 

Augments Water-Based Recreation 

Sand Hollow State Park in Washington County has consistently been the most visited park in 

Utah for several years, with Quail Creek State Park being in or near the top ten7

. Storing and 

managing potable reuse water supply in these reservoirs will increase water levels that would 

otherwise be further depleted under climate change and demand growth. Maintaining the quality 

and quantity of these recreational sites in Washington County helps relieve pressure on 

surrounding congested recreational areas, such as Zion National Park. 

4) Describe the potential for the project to help create additional flexibility to address drought. 

Will water made available by the project being investigated continue to be available during 

periods of drought? To what extent is the water made available by the project being 

investigated more drought resistant than alternative water supply options? Explain. 

In addition to protecting overuse of WCWCD’s drought emergency supply (see Question No. 3 

under Criterion 2 above), water reuse facilities will enhance and diversify the county’s water 

supply portfolio by creating a drought resilient water supply. When drought contingency plans 

are enacted during dry periods, emphasis will be given to maintaining indoor residential use, 

thereby preserving the raw water supply (i.e., sewered return flows) for reuse facilities. Reusing 

indoor water use supplied by local Virgin River Basin sources will also be more drought resistant 

than importing Colorado River water in the LPP. 

EVALUATION CRITERION 3— ENVIRONMENT AND WATER QUALITY 

1) Describe the potential for the project to improve the quality of surface water or groundwater. 

Currently wastewater effluent disposal from Washington County treatment facilities consists of 

holding ponds and land application (ACSSD) or river discharge with seasonal and partial flow 

reuse for irrigation (SGRF). The treatment process alternatives considered for the Regional 

Reuse System each include filtration and advanced water treatment processes that would 

improve the quality of effluent that contacts surface water or groundwater. Expected water 

quality improvements include lower suspended solids or turbidity, less dissolved solids (salts) for 

alternatives that include reverse osmosis, removal or reduction of contaminants of emerging 

concern, and removal of viruses and bacteria.

Washington County Regional Reuse System: Planning 

Technical Proposal and Evaluation Criteria 

2) Describe the potential for the project to improve effluent quality beyond levels necessary to 

meet State or Federal discharge requirements. 

The treatment processes considered for the Regional Reuse System exceed current State or 

Federal wastewater discharge requirements. Resulting water quality is near drinking water 

standard and designed to not impair the quality to groundwater or surface water. For potable 

reuse applications, State or Federal standards are not yet fully developed to address water quality 

or treatment process requirements. However, the treatment processes under consideration for the 

project will produce water quality that meets or exceeds any known standards. 

3) Describe the potential for the project to improve flow conditions in a natural stream channel. 

Under low flow or high temperature conditions in the Virgin River, WCWCD is able to pump 

water from Sand Hollow Reservoir upstream to the Hurricane Hydropower Plant for releases to 

the river. This pump-back operation is coordinated under the Virgin River Program for the 

benefit of Federally-listed fish. Storing and managing potable reuse water supply in Sand Hollow 

Reservoir would increase flexibility in meeting pump-back targets and has potential to improve 

flow conditions in approximately 15 miles of designated critical habitat in the Virgin River. 

4) Describe the potential for the project to restore or enhance habitat for non-listed fish and 

wildlife species. 

Sand Hollow and Quail Creek reservoirs provide large areas of habitat for waterfowl, migratory 

birds, bats, and other non-listed wildlife species in a desert region. Both reservoirs also support 

game fish populations. Storing and managing potable reuse water supply in these reservoirs will 

increase water levels that would otherwise be further depleted under climate change and demand 

growth. Maintaining higher water levels will continue to enhance habitat for these species. 

5) Describe the potential for the project to provide water or habitat for federally listed 

threatened or endangered species. 

The Regional Reuse System may improve designated critical habitat for the Virgin River chub 

(Gila seminuda) and woundfin (Plagopterus argentissimus). See the response to Question No. 3 

under Criterion No. 3 for discussion of improved streamflows. 

EVALUATION CRITERION 4—DEPARTMENT OF THE INTERIOR PRIORITIES 

1) Describe in detail how the proposed project supports a priority: Climate Change. 

Existing potable water supplies are expected to decrease up to 45% (Figure 7) due to climate 

change impacts on Virgin River streamflow and groundwater recharge (also see Questions No. 1 

and No. 2 under Subcriterion No. 1a). Regional planning processes have identified a diverse 

portfolio of future practices and projects, including reuse, which can meet future needs under 

limited local water supplies threatened by climate change. The Regional Reuse System could 

provide a reliable water supply of approximately 47,000 acre-feet per year by 2050 under a 

hotter, drier climate. Reusing local supplies will partly mitigate decreasing water supply due to 

climate change.

2) Describe in detail how the proposed project supports a priority: Disadvantaged or 

Underserved Communities. 

There are 94 census blockgroups in Washington county, most of which are or will be served by 

WCWCD. Several blockgroups are home to disadvantaged and underserved communities8

, as 

follows: 

• Twelve blockgroups have more that 10% of families below the poverty level; five 

blockgroups have more than 20% of families below the poverty level. 

• Sixteen blockgroups have minority populations of more than 20%. 

• Five blockgroups have Native American populations of more than 5%. 

The Regional Reuse System will help protect disadvantaged and underserved communities from 

drought and climate change impacts, and provide sustained economic opportunities. 

3) Describe in detail how the proposed project supports a priority: Tribal Benefits. 

The 2001 Settlement Agreement9 between the Shivwits Band of Paiutes, WCWCD, and other 

parties gives the Tribe the right in perpetuity to 2,000 acre-feet per year of reuse water supply 

from the existing SGRF. The Regional Reuse System will expand reuse treatment, storage, and 

conveyance capacity in the western portion of the county and will help WCWCD and St. George 

continue to fulfill its contractual obligations to deliver water annually to the Tribe.

Technical Proposal and Evaluation Criteria 

EVALUATION CRITERION 5—WATERSHED PERSPECTIVE AND STAKEHOLDER 

INVOLVEMENT 

1) Will the proposed project implement a regional or state water plan or an integrated resource 

management plan? Explain. 

The Regional Reuse System will implement needed actions identified in State of Utah water 

plans. In 2013, Utah’s Governor asked the Utah Division of Water Resources and water 

conservancy districts to develop a statewide “road map” for Utah’s municipal water needs. The 

first Utah Statewide Water Infrastructure Plan or SWIP quantified the state’s future water 

demands and outlined specific conservation, rehabilitation, and new infrastructure needs. 

Multiple projects were explicitly identified as needed actions in the Virgin River Basin, 

including additional reuse. This requirement for additional water reuse investment in the Virgin 

River Basin was reiterated in the 2020 SWIP10 and the state’s 2021 Water Resources Plan11 . 

2) Will the proposed project help meet the water supply needs of a large geographic area, 

region, or watershed? Explain. 

The Regional Reuse System will serve the seven largest communities in Washington County, 

Utah, encompassing 139,615 acres or 218 square miles (see Figure 1). As WCWCD expands its 

services to most of Washington County, the reuse system could serve approximately 2,400 

square miles in the upper and middle Virgin River watershed. 

3) Will the proposed project promote collaborative partnerships to address water-related 

issues? Explain. Describe stakeholder involvement in the project planning process. 

WCWCD has formed partnerships with Washington County municipalities as part of its RWSA, 

and operates its water system in coordination with these cities. In 2022 and 2023, WCWCD held 

workgroup meetings with the RWSA municipal partners to discuss the county’s integrated water 

management plan. Reuse is a major topic in these ongoing meetings. The Regional Reuse System 

will also promote ongoing collaboration between WCWCD and the main wastewater service 

providers, ACSSD and City of St. George, to develop and operate the planned infrastructure. 

4) Will the proposed project include public outreach and opportunities for the public to learn 

about the project? Explain. 

Public outreach has been performed for the Regional Reuse System over the past two decades. 

Dry Wash and Graveyard Wash Reservoirs underwent NEPA analysis in 2004. A public 

information workshop and public comment period were held. It is anticipated other features of 

the Regional Reuse System will undergo further NEPA public processes. The State of Utah does 

not have public outreach guidance regarding direct or indirect potable reuse. It is anticipated that 

public outreach requirements will be similar to surrounding state guidance documents, and 

include a public information repository and public mailings and/or meetings prior to project 

start-up.

Project Budget 

Project Budget 

Funding Plan 

Describe how the non-Federal share of project costs will be provided. Project funding provided 

by a source other than the applicant shall be supported with letters of commitment from these 

additional sources. 

The Federal cost share for Funding Group II under this NOFO is limited to 25% of total 

planning and preconstruction activities. This requirement will limit the federal cost share 

to a maximum of $1,352,638 (Table 8). The remaining amount ($4,057,914) up to the full 

amount ($5,410,553), depending on the Federal contribution, will be the sole 

responsibility of WCWCD. 

WCWCD has developed a general capital funding strategy that will phase-in water rates, 

impact fees, and ad valorem (property) tax increases to produce sufficient revenue 

streams for its future water supply projects, including the Regional Reuse System. This 

project funding strategy, as outlined in the 2019 Applied Analysis economic study12 , 

would produce the following revenue capacity for WCWCD funding: 

• $2.96 billion in impact fees 

• $1.75 billion in water rate increases 

• $1.41 billion in property taxes 

The funding source for planning and preconstruction activities for the Regional Reuse 

System will be obtained from these revenues (Table 8).

Application for Washington County, Utah Regional Reuse System

Dear Commissioner Touton,

We are writing to urge full and fair consideration of the Washington County Water Conservancy

District's (District) 2023 WateTSMART Water Recycling and Desalination Planning grant application. As

one of the fastest-growing regions, the proposed Washington County Regional Reuse System is critical to

diversifring the count¡r's water supply as well as increasing drought resiliency and water sustainability in

the region.

Washington County is moving aggressively to increase conservation and develop local resources. The

Regional Reuse System is a critical component in these efforts. By preserving higher quality water for

potable uses and introducing potable reuse, the Regional Reuse System's water recycling program will

improve efficiency, provide flexibility during water shortages, and diversif,, the count¡r's water supply.

The state of Utah and Washington County have demonstrated their commitment to this innovative project

through significant financial contributions. Extensive investment in infrastructure systems is required to

ensure a safe and reliable drinking water supply. The support of the Bureau of Reclamation's

WateTSMART Water Recycling and Desalination Planning grant will help Washington County increase

Re: Letter of Support, Reclamation WaterSMART Water Recycling and Desalination Planning Application 

for Washington County Regional Reuse System 

Dear Ms. Menendez, 

Thank you for your consideration of the Washington County Water Conservancy District's 2023 

WaterSMART Water Recycling and Desalination Planning grant application. St. George City is pleased to 

support the planning and design of the Regional Reuse System. 

Washington County is one of the nation's fastest-growing regions. Current projections estimate the 

county's population will increase up to 200% by 2060. The county's population depends almost entirely 

on the Virgin River basin for its water. The Virgin River is a small, drought-prone tributary of the 

Colorado River that has been fully developed. In the face of mounting growth, declining water supply, 

and ongoing water shortages, recycling local water resources is essential to protect the county's existing 

and projected economy and population. 

Washington County is moving aggressively to increase conservation and develop local resources. The 

Regional Reuse System is a critical component in these efforts. By preserving higher quality water for 

potable uses and introducing potable reuse, the Regional Reuse System's water recycling program will 

improve efficiency, provide flexibility during water shortages, and diversify the county's water supply. 

Extensive investment in infrastructure systems is required to ensure a safe and reliable drinking water

Washington County is one of the nation's fastest-growing regions. Ctment projections estimate the county's population 

will increase up to 200% by 2060. The county's population depends almost entirely on the Virgin River basin for its 

water. The Virgin River is a small, drought-prone tributmy of the Colorado River that has been fully developed. In the 

face of mounting growth, limited water supply, and long-term drought cycles, recycling local water resources is essential 

to protect th~ county's present and future. 

Washington County is moving aggressively to increase conservation and develop local resources. The Regional Reuse 

System is a crucial component of those effo1ts. By preserving higher quality water for potable uses and introducing 

potable reuse, the Regional Reuse System's water recycling program will improve efficiency, provide flexibility during 

water sho1tages, and diversify the county's water supply. 

Extensive investment in infrastructure systems is required to ensure a safe and reliable drinking water supply. The suppmt 

of the Bureau of Reclamation's WaterSMART Water Recycling and Desalination Planning grant will help Washington 

County increase drought resiliency and water sustainability for the ultimate benefit of all who shm·e the resources of the 

Colorado River basin.
