The wastewater department is responsible for the maintenance of the collection systems and the storm water collection system.
Controlled Discharge Lagoon System
The current wastewater treatment process is a “controlled discharge lagoon” system. This type of treatment is commonly used by small communities across Iowa. With controlled discharge lagoon treatment, all wastewater is held in large storage ponds for a minimum of six months. Over time, natural processes treat and clean the wastewater to a level than can be safely discharged.
Aerated Lagoon System
The Gilbert wastewater treatment system was last upgraded more than 30 years ago. The two eastern ponds were constructed in 1968, and the two western ponds were constructed in 1984. The ponds are located on the Southwest corner of town. The City of Gilbert is currently in the design and permitting stage for upgrading the system to an Aerated Lagoon System.
