Richmond received some very generous grants and no-interest loans both from the State of Utah and the Federal Army Corps of Engineers.
Due to increasing population, industrial growth, and changes in the regulations for discharging treated wastewater, Richmond was faced with the challenge of upgrading their existing lagoon ponds. Because of the renewal of the plant’s wastewater discharge permit, the community was one of the first in the state to fall under the new EPA regulations, particularly the requirement to remove enough phosphorus for safe effluent discharge into the Cub River.
The City Council ultimately selected Ovivo MBR technology for its ability to expand easily and to accommodate process modifications as EPA discharge regulations changed.
