Wastewater Department

The wastewater department is responsible for the maintenance of the collection systems and the storm water collection system.

Aerated Lagoon System

The Gilbert wastewater treatment system upgraded the lagoon system in 2019.  The ponds are located on the Southwest corner of town. The aerated lagoons, also known as SAGR, consists of a clean stone bed that is fully aerated. Water flows through the substrate horizontally, and a layer of insulating wood chips, at the surface prevents ice formation in the bed, allowing the system to treat wastewater that is near freezing (<0.5°C). Lagoons are incredibly powerful ecosystems that cost-effectively, naturally remove a host of wastewater’s most harmful components with a minimum of operations or maintenance requirements.
