      Regional Optimization Master Plan

      Regional Optimization Master Plan (ROMP) is a master plan to allow the Pima County Regional Wastewater Reclamation Department (RWRD) to meet current environmental regulatory requirements mandated by the Clean Water Act.

      What is RWRD planning?

      RWRD is working to meet new environmental requirements mandated by the Arizona Department of Environmental Quality (ADEQ). ADEQ regulates our activities and the way we convey and treat the community’s sewage. ADEQ has directed us to meet more stringent water quality standards for our effluent. These standards are based on mandates set by the United States Environmental Protection Agency (EPA) through the Clean Water Act.

      What new standards does RWRD have to meet?

      ADEQ is mandating that RWRD decrease the amount of nitrogen and ammonia in our effluent.

      Why is it important to decrease nitrogen and ammonia levels in effluent?

      Although nitrogen is helpful in plant growth, it is harmful to aquatic life. Additionally, effluent that is discharged into the Santa Cruz River can percolate into our groundwater and increase nitrogen and ammonia levels in the aquifer. Although small levels of nitrogen naturally exist in the aquifer, high levels of nitrogen in drinking water can be harmful to children and unborn babies. No local water providers draw from the groundwater near the Roger Road and Tres Rios facilities, and the Regional Wastewater Reclamation Department performs regular monitoring of the groundwater in these areas.
