San Angelo City Council Set to Approve $44 Million Bond for Lake Nasworthy Sewer Project

SAN ANGELO – The San Angelo City Council on Tuesday will consider authorizing $44 million worth of bonds to pay for the major sewer line project at Lake Nasworthy during their regular meeting. 

The infrastructure will include a trunk main – a main artery – that eventually could serve other areas that currently must rely on septic systems. This will also provide the framework to eventually eliminate six to eight lift stations.The sewer capacity will increase from 500,000 gallons to 2.5 million gallons per day. That would be adequate to accommodate any development around the lake and at the airport.

Competitive sealed proposals for rebidding the South Concho A Lift Station and Lake Nasworthy Wastewater System Improvements were opened on March 3, 2023.

One proposal was received for the South Concho A Lift Station project and seven proposals were received for the Lake Nasworthy Wastewater System Improvements project. A review committee of five members evaluated the proposals and recommended awarding to Austin Engineering Company, Inc. for Rebid South Concho A Lift Station and McKee Utility Contractors, Inc. for Rebid Lake Nasworthy Wastewater System Improvements.

The contracts will run concurrently with the Lake Nasworthy Wastewater System Improvement project having a contract length of 24 months and the South Concho A Lift Station project having an 18 months contract length with a delayed start of 6 months. RFP WU-03-23 Rebid South Concho A Lift Station project includes a new 2,000 gallons per minute (GPM) wastewater lift station near South Concho Drive. Two pumps will be initially installed, with space to add athird pump. The lift station will also include a backup emergency generator. RFP WU-04-23 Rebid Lake Nasworthy Wastewater System Improvements consists of approximately 10.4 miles of gravity and pressure sewer pipe, 93 manholes, various appurtenances, and other bid itemsconsistent with sewer pipeline construction.

Alternate Bid Item A, which includes parallel force mains for additional capacity, is also included in the project scope. At the February 18, 2020 City Council meeting, the Council approved Task Order No. 2 for the Final Design Phase and Project Bidding Phase to CDM Smith, Inc. In conjunction with the recommendation to award the construction contracts for RFP WU-03-23 Rebid South Concho A Lift Station and RFP WU-04-23 Rebid Lake Nasworthy Wastewater System Improvements, it is recommended that the Council approves Task Order No 3 to CDM Smith to provide construction phase services and resident project representative services.
