Project Description:
This project is located in the southern area of the City’s extraterritorial jurisdiction. The area is experiencing significant growth and increased demand for water and wastewater services. The Austin Water Utility needs to develop and implement a comprehensive Utility Infrastructure Implementation Plan by December 31, 2010. Water system improvements include a new 20- to 30-MGD pump station at the existing Pilot Knob Reservoir, routing and design of 61,000 LF of transmission main in sizes varying from 36-inch to 48-inch in diameter, plus a site evaluation and design of a new 3- to 4-MG reservoir. This project consists of approximately 6,300 LF of 54-inch diameter interceptor from Onion Creek Package Wastewater Treatment Plant. In addition, the project contains a Phase II component which will add additional facilities to enhance the proposed south pressure zone elevated storage tank. CAS is providing engineering and consulting services as a subconsultant to URS Corporation. CAS’ responsibilities include assisting with developing an Immediate Action Plan, reviewing South IH35 Tunnel Project, interviewing/contacting key stakeholders and regulators, developing implementation strategies, and preparing initial schedule and cash flow projections.
