The City of San Angelo invites you to attend a ribbon cutting for the new lift station at Lake Nasworthy. The new infrastructure is a major step in improving wastewater service in the Lake Nasworthy and airport areas, increasing capacity fivefold and providing critical support for future development.
When: 10:30 a.m. Thursday, May 1
Location: 1800 South Concho Drive
Funding for this project came from the Lake Nasworthy Fund approved by voters in 2019 and by bond funds secured by the City Council.
We hope you’ll join us to celebrate this important milestone for our community!
Background information
Project update
The Lake Nasworthy pipeline is approximately 95% complete and scheduled to be commissioned within 60 days.
Project overview
The previous sewer system in the Lake Nasworthy area relied upon a single, uncased pipeline that crossed the lake. This system was installed piecemeal over decades without an overall plan. As a result, it relied upon a complex configuration of 26 lift stations and 106 grinders. The City treats 8 million gallons of wastewater per day. The Nasworthy system produces 500,000 gallons of that total. That means half of the city’s lift stations are dedicated to moving 1/16th of the community’s total wastewater. That’s an inefficient system. The new system includes two cased mains to move wastewater. That provides a failsafe that allows for uninterrupted service should one of the lines fail or require maintenance. And because they are cased, there is a minimized threat of sewage leaking into the environment. The capacity has been increased from 500,000 gallons to 2.5 million gallons per day and will be adequate to accommodate any development around the lake and at the airport. The infrastructure includes a trunk main – a main artery, if you will – that eventually could serve other areas that currently must rely on septic systems. This provides the framework to eventually eliminate six to eight lift stations.
Project cost
In Nov. of 2019 voters approved the use of funds from the Lake Nasworthy Fund to help partially pay for the project. The amount dedicated to this project from the Lake Nasworthy Fund is $11.5 million. The City Council will use a portion of the funds voters approved in the Nov. 2019 special election on several quality-of-life projects at Lake Nasworthy. Those projects include boat ramps, fishing piers, shoreline erosion control and sandy beaches.
Total construction costs for the Lake Nasworthy Wastewater System Improvements project is $31.6 million.
