EXPERTISE SOLUTIONS INNOVATION COMMUNITY CAREERS Owner’s Advisor, Houston Northeast Water Purification Program Client City of Houston Location Houston, Texas Solutions Drinking Water, Program Management, Utility Advisory Services Project Overview The largest progressive design-build water project in the United States In 2012, the City of Houston reached a historic water agreement with state regulators to transition from the traditional drawing of groundwater supplies, which has depleted regional aquifers, to the sustainable use of surface water supplies. More specifically, the agreement requires that, by 2035, the City supplies 80 percent of their water demand using surface water. Although this transition sounds simple in principle, curbing historical reliance on groundwater while still meeting projected water demands in a growing service area demanded the City to develop a $1.8-billion water supply and treatment program that expands their 80-million-gallon-per-day (mgd) Northeast Water Purification Plant with an additional 320 mgd in treatment capacity. The cost of this expansion effort will be shared amongst five regional water providers who will both support and benefit from this far-reaching environmental program. As the technical advisor and owner’s representative for the largest single treatment facility contract in the U.S., Carollo serves as an extension of City staff in facilitating project planning, alternative delivery analysis, procurement, conceptual design, permitting, communications, and overall project controls and management oversight. To avoid significant fines imposed by the State of Texas, this complex project must remain on an accelerated track while meeting critical milestones along the way. To strategically pursue project objectives and foster meaningful collaboration, Carollo and the City established a Project Design and Management Center as their operational hub where the project team defines program goals, standardizes document-management procedures and reporting requirements, and streamlines decision-making processes. Carollo also developed a communal, SharePoint-based project management information system (PMIS) that tracks and monitors cost estimating, scheduling, and risk management through continuous risk identification and response efforts. To date, Carollo has engineered process recommendations and conceptual designs for the treatment facilities, including bench- and pilot-scale testing as well as ultraviolet (UV) validation, and prepared solicitation documents and proposal evaluation guidelines while coordinating closely with City’s legal counsel to develop the design-build agreement. Our ongoing engineering and construction support includes design reviews, value-engineering, and comprehensive construction oversight. 1 2 3 4 5 Results and Highlights A $1.8-billion water supply and treatment program.
