Welcome to the Davenport Recycled Water Project!

The Davenport Recycled Water Project (DRWP) is a project to upgrade the existing wastewater treatment plant in Davenport. This project will upgrade the Davenport County Sanitation District’s wastewater treatment plant by dredging accumulated solids in the treatment lagoon, installing alarms for the filtration and disinfection processes, and adding redundancy for coagulant and hypochlorite dosing. The project also consists of the construction of a storage pond for treated water, which will allow adjacent farmers to use recycled water for irrigation.

December Update

Dredging of the wastewater treatment lagoon started on November 30th. The dredge (red piece of equipment in the pond shown in the picture) cuts and “vacuums” up accumulated sludge from the bottom of the pond and sends it to a holding tank. The sludge then goes through a grinder, after which a polymer is added before it enters a centrifuge where liquid is taken out. The dried sludge is loaded into trucks (it takes about 4 hours to fill one truck) and the liquid is returned to the pond. The dredging process is expected to take 3-4 weeks.
