Garver’s unique approach mitigated the market volatility’s impact on supply chains
The City of Huntsville’s Western Area Wastewater Treatment Plant (WWTP), originally constructed in 1980, has undergone two expansion projects since originally constructed. Garver provided design and bidding services and is currently providing construction administration services for the third expansion to increase the overall treatment capacity from 20 to 25 MGD. These include construction of a new secondary treatment train consisting of an oxidation ditch with anoxic selector basin and a secondary clarifier.
Additional improvements include expansion and rehabilitation of the existing headworks facility to a peak treatment capacity of 87.5 MGD, a new oxidation ditch splitter structure to receive RAS and evenly distribute flow to each of the three oxidation ditches, and a new common RAS/WAS pump station to serve all secondary clarifier units. To compensate for supply chain issues and market volatility and to begin the construction effort as quickly as possible, Garver developed a unique design and project strategy to mitigate these issues with detailed design for the improvements completed in just seven months.
Additionally, Garver coordinated and led equipment pre-selection and pre-negotiation during design as well as developed details of the major yard piping elements at the 30% design stage to allow Huntsville to pre-purchase all large diameter yard piping.
