CIA Engineers provided grant application, preliminary design, design documents, and construction administration to convert the facultative lagoon at the Camden Wastewater Treatment Plant (WWTP) into a more energy efficient, lower maintenance, lower operating cost partial-mix system. This project was 100% funded by an Energy Efficiency Community Block Grant (EECBG). The grant was used to provide engineering planning, design and construction services as well as to procure and install two solar-powered mixer/aerators in the facultative lagoons at the WWTP.

The two new solar-powered mixer/aerators, in conjunction with three existing solar-powered mixer/aerators and four solar-powered mixer/aerators to be added in the Phase II WWTP Improvements project, will serve to convert the existing facultative lagoon system into a partial-mix system.

The new configuration will allow the WWTP to achieve and maintain compliance with existing and future National Pollutant Discharge Elimination system (NPDES) permit limits for BOD5, DO, and ammonia, and extend the WWTP’s operating viability for the next 20 years.

These improvements will be accomplished at the lowest possible operating cost since all of the aerators are 100% solar powered. The project was completed on time and under budget.
