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.

June Update

The construction of the recycled water force main in Cement Plant road is progressing.  Construction crews uncovered multiple unexpected underground utilities and obstacles during construction of the force main, causing delays.  We appreciate your continued patience during this period of traffic detours.

This week construction crews will be beginning the jack and bore operation under the railroad tracks and Highway 1.  This work will provide the farmer on the ocean-side of Highway 1 with the ability to irrigate the farmland with recycled water from the treatment plant in the future.

Also beginning this week is grading work for the recycle water storage pond located on the property along Warnella Road.  The recycled water in the storage pond will be used by the property owner for irrigation and will be available for the general public to purchase at the recycled water fill station.  Purchasers of the recycled water must pre-register with the Davenport County Sanitation District and agree to only use the recycled water for approved uses.

April 25th Update

Dredging of the wastewater treatment lagoon was completed in mid-December.  Upgrades to the recycled water treatment plant are nearly complete.  Construction of the waterline along Cement Plant Road (extending from the treatment plant to the storage pond on the farmland property) will begin soon.  In preparation, construction crews will be potholing the road in the next couple of weeks.  Traffic will be diverted around the construction crews as needed during this time.  Over the next two months as the waterline is constructed, detours will route traffic around the closed portion of Cement Plant Road via Highway 1 and via Adeline Street.  The detour will be in place from around 8:00 am to 5 p.m.  Mondays through Fridays.

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.

November Update

Spiess Construction is continuing to work at the existing treatment plant. Dredging operations of the existing lagoon are scheduled to begin the week of November 13th and should last about a month. Residents may see an increase in truck traffic during this time as the dredged material is hauled away.

The project was awarded to Spiess Construction Company Inc. (SCCI) of Santa Maria, California. SCCI plans to start work dredging the existing wastewater lagoon in September.
Construction of the pond as well as jack-and-bore operations under Highway 1, will begin in the Spring.
