Title
Consider a resolution authorizing the Mayor to execute an lnterlocal Agreement with the City of Austin, City of Cedar Park and City of Leander regarding allocation of costs for the rehabilitation of the East Wastewater Treatment Plant of the Brushy Creek Regional Wastewater System.
Body
The City of Round Rock’s wastewater flows into the Brushy Creek Regional Wastewater System (BCRWWS). The regional system is owned by the City of Round Rock, City of Cedar Park, City of Austin, and City of Leander. The BCRWWS consists of two wastewater treatment plants (WWTP), the East WWTP and the West WWTP. The East WWTP is currently under construction to increase the capacity to 30 million gallons per day (MGD), bringing the total treatment capacity of the BCRWWS to 33MGD.
The City of Round Rock recently contracted with Plummer and Associates, Inc. for design of another 10MGD expansion, which will increase the East WWTP capacity to 40MGD. The project will add a fourth treatment train, two clarifiers, and associated filtration and disinfection. In addition to the expansion to 40MGD, the existing WWTP is in need of rehabilitation. Existing treatment structures, equipment, and other components across multiple areas of the plant will be included in the rehabilitation and will be designed, bid, and constructed along with the 40MGD expansion project. Costs associated with rehabilitation will be allocated according to the 30MGD ownership percentages.
This request is for an interlocal agreement (ILA) between the City of Round Rock, City of Cedar Park, City of Austin, and City of Leander, for the allocation of costs for the rehabilitation of the BCRWWS East WWTP as part of the expansion to 40MGD project. The City of Round Rock cost allocation for rehabilitation project costs is 60.76%.
