The Advanced Water Treatment Facility is located on Stapleton Avenue and is part of the City’s water conservation and management program, which seeks to ensure a safe and sustainable water supply. To ensure the City's water future, the City is seeking more efficient means of utilizing all available water resources. This project helps to replenish the aquifer and to minimize the need to discharge recycled water to the Rio Grande. The City of Rio Rancho is funding this project through the New Mexico Finance Authority (NMFA) Water Trust Board loan and grant funding, which requires a 20% match from City funds.

The construction phase will include installation of advanced oxidation treatment equipment, retrofitting the direct injection Well for routing backwash operations, completion of controls, and associated site improvements to direct inject high-quality recycled water into the aquifer.

What is Advanced Oxidation Treatment? Advanced oxidation is a chemical treatment process designed to remove organic materials in wastewater through ozone, hydrogen peroxide, and/or ultra-violet light. The advanced oxidation procedure (AOP) is particularly useful for cleaning biologically toxic or non-degradable materials such as aromatics, pesticides, petroleum constituents, and volatile organic compounds in waste water. Additionally, AOPs can be used to treat effluent of secondary treated wastewater which is then called tertiary treatment. The contaminant materials are converted to a large extent into stable inorganic compounds such as water, carbon dioxide and salts (i.e. they undergo mineralization). A goal of the waste water purification by means of AOP procedures is the reduction of the chemical contaminants and the toxicity to such an extent that the cleaned wastewater may be reintroduced into receiving streams, into a conventional sewage treatment, or direct injected into the aquifer.
