Welcome to the
Wastewater Reclamation Authority

The Des Moines Metropolitan Wastewater Reclamation Authority is made-up of 17 metro area municipalities, counties and sewer districts. They work together to protect public health and to enhance the environment by recycling wastewater and being the preferred treatment facilities for hauled liquid wastes.

In 2004, the Des Moines Metropolitan Wastewater Reclamation Authority retained the City of Des Moines as the Operating Contractor to provide operation, maintenance, and management services for the Wastewater Reclamation Authority

 The WRA includes a conveyance system and a treatment facility. The conveyance system connects each of the participating communities in Dallas, Polk and Warren Counties to the wastewater treatment facility. The system includes 125 miles of sanitary sewer with pipe sizes up to 144” in diameter, equalization basins and lift stations.

The treatment facility uses a combination of physical, advanced biological and chemical processes to treat the wastewater as it flows through the plant.  These processes produce high quality recycled wastewater discharged to the Des Moines River, treated biosolids that are land applied on farm fields for nutrient value and soil amendment, and biogas utilized for electrical and heat generation.

In 2013, we

  • Served a population of ~500,000
  • Treated an average 59 MGD for a total of 21.5 billion gallons
  • Applied 64,573 wet tons of biosolids on 1611 acres
  • Created an average of 1,250,000 cf/day of digester biogas for a total of 458,000,000 cf
  • Produced 42% of our own electricity
  • Consumed an average of 88,400 kWh/day of electricity for a total of 32,300 megawatt hours
