Title
Consider a resolution authorizing the Mayor to execute Supplemental Contract No. 1 with Plummer and Associates, Inc. for the BCRWWS East Wastewater Treatment Plant Expansion to 40 MGD Project.
Body
The City of Round Rock’s wastewater flows into the Brushy Creek Regional Wastewater System (BCRWWS) which 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 nearing completion of an expansion to increase the capacity to 30 million gallons per day (MGD), bringing the total treatment capacity of the BCRWWS to 33 MGD.
The City of Round Rock recently contracted with Plummer and Associates, Inc. for design of another 10 MGD expansion, which will increase the East WWTP capacity to 40 MGD. The project will add a fourth treatment train, two clarifiers, and associated filtration and disinfection. In addition to the expansion to 40 MGD, 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 40 MGD expansion project. Costs associated with rehabilitation will be allocated according to the 30 MGD ownership percentages.
This request is for the approval of Supplemental Agreement No. 1 with Plummer and Associates, Inc. for design of the rehabilitation of the East WWTP as part of the expansion to 40 MGD project. The total cost of the Supplemental Agreement No. 1 is $1,256,618.00. The City of Round Rock cost allocation for Supplemental Agreement No. 1 is based on 60.76% capacity ownership (based on 30 MGD capacity) is $763,521.10.
Cost: $1,256,618.00
