The existing North Bentwood Lift Station (NBLS) was constructed in the 1970s and had reached the end of its service life.  This lift station receives wastewater flow from gravity mains and force mains from multiple upstream lift stations, resulting in high levels of hydrogen sulfide gas and a very aggressive corrosive environment. The existing lift station wet well was constructed of concrete and had deteriorated to the point that immediate and full replacement was required.

eHT provided project management, design and construction administration for the NBLS for the City of San Angelo. The project included a new lift station to replace an existing lift station, electrical and controls, bypass pumping, site fencing and gates, and new gravity and pressure sewer mains to connect to the existing collection system in the Bentwood area of the City.

To handle this aggressive environment, the replacement lift station wet well was competitively bid between fiberglass and corrosion-resistant concrete. Fiberglass was the more economical option and was used.
