SUBJECT
Title
Authorize a professional services contract with Lockwood, Andrews, and Newnam, Inc. for engineering evaluations, preliminary design, development of construction plans and specifications, bid phase services, construction administration and start-up associated with non-potable water system improvements at Central Wastewater Treatment Plant - Not to exceed $3,397,000.00 - Financing: Wastewater Construction Fund
Body
BACKGROUND
The City of Dallas owns and operates two wastewater treatment plants with a combined treatment capacity of 280 million gallons per day. Central Wastewater Treatment Plant (CWWTP) is the largest of the two plants, located just south of downtown. The non-potable water system at CWWTP utilizes treated wastewater for various plant water demands, conserving potable water. Non-potable water is used for filter backwashing, equipment cooling, and mechanical seal water. The current non-potable system consists of a main pump station, storage tank, booster pump station, pipelines, and appurtenances. These facilities have been constructed over the years as the plant has grown and treatment needs have changed.
The existing non-potable water infrastructure does not meet plant needs and results in increased operation and maintenance costs. Some of these facilities have reached the end of their useful life and the demand for non-potable water has also increased due to improvements in several processes throughout the plant. The proposed improvements will ensure that the non-potable water system is sufficient to satisfy current and future volume and pressure demands and protect critical equipment and infrastructure within the plant. The final design shall meet or exceed all anticipated capacity requirements and include flexibility to operate efficiently at any demand, ranging from minimum day demand to peak day demand.
This action will authorize a professional services contract with Lockwood, Andrews, and Newnam, Inc. to perform engineering services associated with non-potable water system improvements at the plant. Services include condition assessments of existing facilities, subsurface investigations of existing infrastructure, hydraulic modeling of the existing system and future system improvements, and analysis of system improvement options. The recommended improvements will be designed, and construction documents will be prepared. Additional professional services include bidding assistance, construction administration, and start-up of the proposed improvements.
