SUBJECT
Title
Authorize (1) an increase in appropriations in an amount not to exceed $799,902.40 in the Water Construction Fund; and (2) a professional services contract with Carollo Engineers, Inc. to provide engineering services for the evaluation of the feasibility, reliability and resiliency of optimizing existing water supply and raw water transmission infrastructure to meet municipal water supply demands in the North Central Texas region - Not to exceed $1,199,853.62 - Financing: Water Construction Fund
Body
BACKGROUND
Dallas and the North Central Texas Region are experiencing rapid business and population growth with accompanying increased demands for municipal and industrial water supplies. Dallas’ Long-Range Water Supply Plan (LRWSP) since the drought of the 1950’s has guided Dallas’ to develop a geographically, hydrologically, climatically, and geologically diverse water supply system.
North Texas Municipal Water District (NTMWD) and Tarrant Regional Water District (TRWD) have also developed diverse water supply systems to meet the needs of their respective service areas. Although, Dallas, NTMWD, and TRWD service areas are adjacent, the water supply and raw water transmission systems are not interconnected and are operated independently, with very few exceptions like the Integrated pipeline with TRWD and the exchange of reuse with NTMWD. Due to the unique geographical, hydrological, climatic, and geological characteristics of the Dallas, NTMWD and TRWD water supplies, joint system operation has the potential to generate additional water supply for the region.
On August 10, 2022, the City Council authorized an Interlocal Agreement between Dallas, NTMWD, and TRWD to jointly evaluate the feasibility, reliability, and resiliency of optimizing existing water supply and raw water transmission infrastructure to meet municipal and industrial water supply demands in the North Central Texas region in an estimated study cost of $1,200,000.00. The three agencies will share the cost of the study equally with Dallas managing the study.
The proposed study will evaluate the joint operation of the water supply system for yield optimization and identify opportunities within the water supply system and associated raw water transmission infrastructure to take advantage of the identified increased yields.
This action will authorize a professional services contract with Carollo Engineers, Inc. to complete the regional optimization study. Carollo Engineers, Inc. was selected following a qualifications-based selection process in accordance with City of Dallas Administrative Directive 4-05 procurement guidelines.
