Advanced reverse osmosis design
A four-stage RO system achieves 94–96% recovery, far exceeding the 75–85% typical for brackish treatment systems.
As population growth and persistent drought placed increasing pressure on its limited groundwater resources, East Cherry Creek Valley Water & Sanitation District (ECCV) implemented an advanced four-stage reverse osmosis (RO) system that transforms brackish groundwater into a reliable, high-quality and environmentally responsible drinking water source for the future.
A four-stage RO system achieves 94–96% recovery, far exceeding the 75–85% typical for brackish treatment systems.
Two deep-injection wells safely pump the concentrate 10,000 feet underground, making ECCV a national pioneer in the method.
At $2.80 per 1,000 gallons, water production costs are one-third of the industry benchmark for brackish RO facilities.
Facility expansion, automated cleaning processes and RO stages deliver long-term reliability and maintenance.
ECCV’s high-recovery RO facility has set new performance benchmarks for municipal utilities, reducing brine volume by 70% while achieving sustainable supply for one of the nation’s fastest-growing regions. “We had to bring all our past projects and R&D experience to figure out a way to make it work,” said Tim Rynders, our discipline leader for water treatment process and piloting.
