Provenance Engineering performed a value engineering review of this $4.3-million lift station with a 25-mgd design capacity. A thorough and meticulous review by the Provenance Engineering team, compounding factors of safety were identified in the original design. Our team identified improvements that could save the city an estimated $1 million. We worked closely with the city to: evaluate a cost reduction alternative, provide an option to improve operations, and carefully review TCEQ requirements.
Challenges
The value engineering portion of this project had to be expedited by Provenance Engineering because the construction of the project was already underway. Results had to be given to the City before the general contractor reached the point of no return. Provenance found that all wastewater flowed through one pipe, leading to a choke point, which created a high risk of failure situation.
Solutions
Provenance proposed raising the floor of the lift station by 11 feet after identifying a 15.0 safety factor in the wet well design volume. The lift station was 55-feet deep, of which 35 feet was solid rock, so recalculating storage volume was a necessity. We also proposed extending the discharge pipe 100 feet into the Wastewater Treatment Plant Head Works Facility, bypassing a single point of failure for the entire city’s wastewater system, so that if a failure occurred, the wastewater pipe could continue to serve the City.
