City of Waco Selects LAN to Design New Lift Station and Force Main
May 11, 2015
The City of Waco selected Lockwood, Andrews & Newnam, Inc. (LAN) as the prime engineering consultant to replace the existing LaSalle Lift Station and force main that serves the Waco Metropolitan Area Regional Sewer System (WMARSS).
WMARSS owns, operates and maintains a total of five major lift stations and associated gravity interceptors within its collection system. The LaSalle lift station is the third largest in the system and currently conveys peak flows of approximately 30 million gallons a day from the cities of Waco, Lacy Lakeview and Bellmead to WMARSS’s central treatment plant.
A major portion of the WMARSS collection system is more than 40 years old. A recent condition assessment identified numerous repairs, replacements and improvements needed to avoid structural pipe failures and potential sewer system overflows. The existing LaSalle Lift Station, located along the east bank of the Brazos River above the low-water dam that forms Lake Brazos, was identified as the highest priority project needing immediate consideration.
“This is a critical project for the City of Waco and WMARSS,” said Tom Ray, P.E., LAN’s water resources program manager. “The existing LaSalle lift station is located in a saturated, wet soil area that is subject to sloughing. It also needs additional pumping capacity. With the proposed improvements, the City will be able serve the region for the next 30-40 years and avoid sewer overflows.”
LAN will provide engineering services in two phases. Phase I engineering work will involve (1) analysis of alternatives and proposal of a recommended project, and (2) preparation of the preliminary design for the recommended project. Phase II work will involve final design services, including acquiring all required permits, environmental reviews and easements.
