Project Spotlight: City of Taft WWTP April 11th, 2017

The City of Taft’s Wastewater Treatment Plant (WWTP) was constructed in 1974. Over time, equipment began to fail and replacement parts became harder to find. Wallace Group was contracted to find a cost effective, efficient alternative design for the plant. Goals for the improvements were to replace various components and improve treatment capability in order to meet Waste Discharge Requirements. Another goal was to bring some of the lagoons back into working order to build redundancy so that any necessary repairs needed in the future could be addressed without having to shut down the entire plant. Various improvements across the plant included new headworks and an influent flow meter, new aeration system and blower building, and a new septage receiving station. As part of the new septage receiving station, a card system and cameras were installed in order for the City to have remote access 24/7. The station was placed outside of the plant’s perimeter fence so that commercial haulers and recreational RV’s could have access as well.

Some of the project challenges included having separate contractors working simultaneously during the sludge removal stage, a 5-year process to receive a USDA loan, and such high temperatures that concrete for the blower building had to be poured at night in order to prevent shrinkage cracking.

However, this multidisciplinary project has been hugely successful. The project involved our engineering (civil, water resources, and mechanical), surveying, and construction management departments. Wallace Group’s innovative design saved the City millions of dollars in fees, and the contractor finished all work within the allotted time. We are proud of our team, and we look forward to future work with the City of Taft!
