This project involved the construction of a triple-train sequential batch reactor (SBR) process to pretreat highly concentrated wastewater returned to the main treatment plant by nitrifying the wastewater stream using high speed turbo air blowers. Each basin independently treated the wastewater by blowing air through fine bubble diffusers which nitrifies the wastewater making it easier for the main BNR process to reduce the ammonia content in the secondary effluent. To maintain the correct alkalinity, a stand-alone dry lime facility was constructed to create slurry that feeds into the SBRs via a computer-controlled process system.
This project won the APWA Sacramento Chapter Project of the Year Award in the Environmental Category.
Included with the project was:
- A new electrical building and control room
- Effluent pump station
- Washdown water pump station
- A stormwater pump station

“I love construction. Being part of a project – especially a difficult one, fuels the drive within me to build it, build it right, make significant contributions to its success. I seek to please our clients with every aspect of each water related infrastructure construction project so they will want me to support them on their next project.”
