DiNatale Water Consultants assisted the East Cherry Creek Valley Water and Sanitation District with Colorado Department of Public Health and Environment NPDES discharge permitting for the return flow from its planned 10 million gallon per day reverse osmosis water treatment facility. DiNatale Water is also assisting the District in water quality protection activities.
DiNatale Water Consultants is representing the United Water and Sanitation District as a Board member for the Barr-Milton Watershed Association. This Association is developing TMDLs for Barr and Milton Reservoirs in Colorado. Mr. DiNatale led the establishment of the Standley Lake and Clear Creek water quality monitoring programs and was the lead negotiator for the Clear Creek Watershed Management Agreement. At the time he started at Westminster in 1980, Standley Lake was experiencing significant and regular taste and odor events. The successful implementation of the comprehensive watershed and reservoir management plan has resulted in no taste and odor events since 1988 and the delay of the need to implement hypolimnetic aeration. He also proposed and implemented the in-situ testing of midfoil weevils for Eurasian water milfoil control. Mr. DiNatale presented expert testimony in Colorado Division 1 Water Court on the impacts of wastewater discharges on reservoir and drinking water quality that contributed to a favorable court ruling, eventually leading to a comprehensive settlement of water quality issues on Clear Creek.

Under Mr. DiNatale’s direction, CDM, working with Alex Horn Associates, conducted an evaluation of in-lake water quality management options to mitigate taste and odor issues at the Marston WTP. Denver Water then engaged CDM to design the selected approach — a new oxygenation unit that was implemented on a fast-track schedule.
