Subject: Proposed Water Need Methodologies for Long-term Contract Renewal - Central Valley

Project

On October 23, 1998, Reclamation’s Mid-Pacific Region announced its intent to undertake a

water needs assessment for each contractor as a part ofthe forthcoming Central Valley Project

(CVP) long-term contract renewal process. The announcement advised that workshops would be

held to address the development ofwater demand methodologies for both irrigation and

municipal and industrial (M&I) purposes as the first step in the overall water needs assessment.

These workshops were held November 2 - 16, 1998.

The purpose of the attached document is to lay out the entire proposed methodology for the water

needs assessments. The workshops focused primarily on methodologies to estimate historic

irrigation and M&I water demand and provided the public an opportunity to comment on the

draft methodologies and seek additional clarification.

This documenthas been posted on Reclamation’s website and distributed to interested parties to

provide additional opportunities for workshop participants and others to comment on the

proposed water needs assessment methodology. Once this document has been finalized, it will

be posted on Reclamation’s website to allowinterestedparties to understand the methodology

Reclamation proposes to use in assessing water needs in connection withthe long-term contract

renewal process. Reclamation’s Mid-Pacific Region website can be found at www.mp.usbr.gov

.

For additional information or questions regarding the proposed irrigation water demand

methodology, please contact Mr. Joel Zander at (916) 978-5270 (TDD 978-5608). Questions

related to the M&I water demand methodology may be directed to Ms. MarshaPrillwitz at

(916) 978-5213 (TDD 978-5608). Written comments on the draft water needs assessment

methodologies may be submitted by COB December 11, 1998, to Ms. Donna Tegehnan, Bureau

of Reclamation, MP-440, 2800 Cottage Way, Sacramento, CA 95825.

PROPOSED WATER NEED METHODOLOGIES,~’

LONG-TERM CONTRACT RENEWAL

CENTRAL VALLEY PROJECT

STEPS IN ASSESSING WATER NEEDS. The proposed water demand methodologies discussed in

the workshops will be used to demonstrate historic beneficial use ofwater from both CVP and non-CVP

sources. The second step in the process is the determination of future demand for irrigation and M&I

water during the term of the renewal contract, again using the proposed water demand methodologies.

The final step in the process will be the determinationofneed forCVP water based on comparisons of

future waterdemands and non-CVP watersupplies foreachcontractor. Iftheneed for C’VP water

exceedsthe current maximum contract amount, the contract amount will not necessarily be

augmented. Conversely, ifthe need for CVP water is less than the current maximum contract

amount, Reclamation maytake steps to reduce the contractamount.-

IRRIGATIONWATER DEMAND ANALYSIS. Reclamation proposes to relyupon the following

generally accepted dataand principles to determine historic and projected demand for irrigation.

• Historic Crop Database. Reclamation’s existing crop database for individual CVP contractors

encompasses a 15-year period from 1979 through 1993. The contractors will be asked to confirm

the accuracy ofthis data and provide crop information from 1994 through 1997 to document

recent crop rational trends.

• Projected Crops. The more current data will reflect more recent trends, which could be

pertinent to the contractor’s future demands. Reclamationwill work with the individual

contractors to project future cropping patterns. Reclamation will compare these projections with

other informational sources,such as Bulletin 160-98, to assess the reasonableness of the

projections.

• Annual Evapotranspiration Requirement (ET). ET is provided by crop and geographic

location in the Department of Water Resources’ (DWR) Bulletin 113-3 (Bulletin 113). Actual

ET requirements in a particular service area may vary somewhat from that of the geographic

locations reported in Bulletin 113 as a result ofvarious local factors (e.g., soil type, crop variety

and climate). Location-specific ET published by local agencies, universities, and/or cooperative

extensiens will be used, if available.

• Annual Effective Precipitation (EP~. EP is shown in Bulletin 113, Tables 23 and 25, [EP= ETET of applied water(ETAW)]. These tables are attached.

• Crop Irrigation Requirement (Cm). CIRis also shown in Bulletin 113, Tables 23 and 25.

CIR may also be referred to as ETAW, which equals (ET - EP).

• Cultural Practices Requirement (Ci’). CP is reflective of crop needs in specific contractor

locations. CP which varies by yeartype, provides waterneeded forcrop quality, germination

irrigation, and weed and climate control. These practices maychange over time.

• Leaching Requirement (LR). The LR is established to ensure no yield loss due to salinity

effects on the root zone of the crop. LRis calculated consistent with Foodand Agricultural

Organization (FAO) Publication 29, Rev. 1 and ASAE Monograph #3, Design and Operation of

Farm Irrigation Systems, 1980, Chapter 5, “Salinity in Irrigated Agriculture.”
2

• Average On-Farm Irrigation Efficiency (SE). SE is assumed for each contractor consistent

with farm operating units regarded as characteristic ofthe contractor’s service area and

compatible with recent and futurewater conservation strategies deemed practicable forthe

service area. As a rule of thumb, 75 percent SE is currently considered to be representative of

most areas in California, unless more specific information is available. By the year 2020,

Bulletin 160-98 assumes SE to be 80 percent and CALFED assumes it to be 85 percent.

To facilitate dataprocessing, Reclamation proposes to consolidatethe total number ofcropsreported by

all contractors from approximately 86 to 22 general crop categories, and, unless otherwise determined to

be inappropriate, will exclude those crops grown less than 3 out of the 19 years. Each general category

will include crops having similar LR and ET requirements. -‘

The estimated historic and projected water demand for each irrigated crop will then be calculated and

used to determine a weighted average historic and projected Fann Delivery Requirement (FDR) for the

consolidated crop categories in the contractor’s service area. A computer software program entitled the

FDR Program, which was first fully automated by Reclamation in 1986, and has been slightly modified

by Reclamation, will be used to accomplish these calculations. The program is largely consistent with the

irrigation water demand calculations employed by the University of California, California Polytechnic

University at San Luis Obispo, and FAQ. The program relies upon the following algebraic formula:

FDR (AF/acre) = CIR/[(SE/l00)(l-LR)] + Ci’

Where, CIR = ET-EP = ETAW (Bulletin 113-3)

SE on-farm system efficiency, and

LR = leaching requirement = EC w/[5(ECe)-ECw]

Ci’ = cultural practices

ECw - electrical conductivity ofapplied water

ECe - salinity threshold limit ofcrop

AF = acre-foot

Following computation ofthe average historic and projected FDR, Reclamation will calculate and

evaluate the total historic and projected irrigation water demand as follows:

• Total Irrigation Water Demand = Irrigation Water Demand + Distribution System Losses

where:

Irrigation Water Demand = FDR X Irrigated (Productive) Acres’

The above calculation will be influenced by possible changes in the contractor’s cropping patterns, crop

genetics, urbanization, economic considerations, improvements in on-farm irrigation systems over time,

and other factors. Reclamation will work with contractors on an individual basis to include the effect of

these factors in determining total historic and projected irrigation waterdemand.

The second component ofthis equation, i.e. distribution system losses, has previously been determined

for historic conditions by many ofCVP contractors and included in thewater conservation plans,

Lands which are,actually in production and are being served project water.
3

submitted by the contractors to Reclamation. The calculation offuture distribution system losses may

reflect improved water management practices and/or increasing system efficiencies over time.

IRRIGATION WATERNEED ANALYSIS. Following computation ofthe total historic and projected

irrigation water demands, Reclamation will estimatethe total potential CVP irrigation need for all

contractors. This will be accomplished in consultation with the individual contractors. The computation

will reflect available non-C VP water supplies, including ground water and non-CVP surface supplies as

follows:

• Total Potential CVP Irrigation Need of the Contractor = Total Projected Irrigation Demand -

Non-CVP Water Available

[Note: There must be a demonstrated need for CVP water, however, ifthe Total Potential CVP

Irrigation Need ofthe Contractor exceedsthe Contractor’s current maximum CVP water

service contract amount, the CVP water service contract amount will not necessarily be

augmented.]

M&I WATER DEMAND ANALYSIS. Generally, annual M&I water demand consists ofthe

following components: Residential Demand, Nonresidential Demand, and Distribution System Demand,

each of which is discussed below. The followingequation is proposed to be used to calculate current and

projected M&I waterdemand. Anumber ofthe parameters will likely change for the projected

calculations due to water conservation efforts.

• Total M&I WaterDemand = Total Residential Demand + Total Nonresidential Demand +

Total Distribution System Demand

Projected M&I water demand will be influenced over time by many factors, including future land use

changes, population shifts, and improvements in residential and distribution system efficiencies over

time. These factors are reflected in Residential Demand, Nonresidential Demand, and Distribution

System Demand for each contractor, as follows, and will be assessed in consultation with the individual

contractors:

Residential Demand. Residential demand equals the number ofresidents times a per capita factor for

indoor demand, plus the acreage of residential landscape times an evapotranspiration (ET) factor for

outdoor demand:

• Total Indoor Demand (AF / Year) = Number ofresidents X gpcd X 365 (days/year

)

325,851 (gallons/AF)

gpcd = gallons per customer per day

Reclamation proposes to use 75 gpcd to estimate current residential demands and 55 gpcd to project

future residential demands, consistent with the planning assumptions put forth by CALFED. Such

assumptions may not be appropriate for all contractors and locations.

• Total LandscapeDemand (AFIYear) = Acreage Irrigated XETo (inches) X ET Factor

12 (inches/foot)
4

Reclamation proposes to use 100 percent for the ET Factor to determine currentresidential landscape

demands and 80 percent for the ETFactor to estimate future demands, consistent with the planning

— assumptions put forth by CALFED. The attached excerpt from the California Model Water Efficient

Landscape Ordinance contains information on ETo. Again, such assumptions, which are intended to

reflect increasing water use efficiency over time, maynot be appropriate for all contractors and locations.

• Total Residential Demand = Total Indoor Demand + Total Landscape Demand

Nonresidential Demand (Commercial. Industrial. Institutional). For current conditions,

nonresidential demand is assumed to equal the average amount of water used indoors over the past

5 years plus the acreage ofnonresidential landscape times an ETFactor, as shown below. For the

purposes of projected demand, current demand will be adjusted to reflect changes (increases or other

adjustments) in land use as may be reflected in regional land use or planning studies, DWR publications

or otherdocuments. M&I contractors will be asked to identify any major changes to projected

nonresidential demands, such as siting of water-intensive industrial facilities, based on theirregional land

use plans or other information. Assumptions regarding the ETFactor are consistent with that presented

for computation of residential demand. Specifically,

• Total Nonresidential Demand = Total Indoor Demand + Total Landscape Demand, where

• Indoor Demand (AF/Year) = Average February2 Water Use (Prior 5 Years) x 12

(months)

• Landscape Demand (AF/Year) = Acreage Irrigated X ETo (inches) x ET Factor

12 (inches/foot)

Distribution System Demand. Distribution system demand equals water used for unaccounted

beneficial uses and distribution system losses as discussed below.

Unaccounted Beneficial Use includes water uses such as firefighting, mainline flushing,

stormdrain flushing, sewerand street cleaning, construction site use, water quality, and other

testing.- Unaccounted Beneficial Uses may be estimated as follows:

• Unaccounted Beneficial Uses (AF/Year) = Actual number ofAF / Yr of Unaccounted

Beneficial Uses,or, as an estimate, 1 to 2 percent ofAverage Total Interior and Exterior

Use for previous 5 years

Distribution System Losses includes water uses such as leaks in storage and distribution

systems, evaporation, illegal connections, and water theft. Distribution system losses may be

estimated as follows:

• Distribution System Losses = Actual number ofAF / Yr of Distribution System Losses,

or, as an estimate, approximately 7 percent of Average Total Interior and Exterior for

previous 5 years

2 The month of February was suggested as that month is expected to more accurately demonstrate monthly

interior water demands in situations where landscape (exterior) water demands are not typically metered separately.
.4 5

Therefore, total current and projected distribution system demand is calculatedas follows:

• Total Distribution System Demand = Unaccounted Beneficial Uses + Distribution System

Losses

M&I WATER NEED ANALYSIS. Following computation of the total current and projected M&I

water demands, the potential need forGyP M&I waterwill be calculated as the difference between total

M&I water demand and the supply available from non-CVP sources. These determinations will be done

in consultation with CVP M&I contractors.

• Total Potential CVP M&I WaterNeed = Total M&I Water Demand - Non-CVP Water

Supplies

[Note: There must be a demonstrated need for CVP water, however, ifthe Total Potential CVP

Irrigation Need ofthe Contractor exceeds the Contractor’s currentmaximum CVP water

service contract amount, the CVP water service contract amount will not necessarily be

augmented.]
