UCONN Chosen as WateReuse Institution of the Year

The treatment train selected for the University of Connecticut’s cutting-edge wastewater reuse program. Microfiltration will be used to treat wastewater effluent before it is used for industrial feedwater and turf irrigation. Treated water from the MF/UV process will then be sent to an upgraded Ion Exchange and Reverse Osmosis system for use as feedwater for the Central Utilities Plant boilers. The RO permeate will be further purified using electrodialysis for steam attemperation feedwater.

(ROCKY HILL, CT – September 20, 2011) – The WateReuse Association has chosen the University of Connecticut as the recipient of the 2011 WateReuse Institution of the Year Award, an award that recognizes institutional projects whose significance and contributions to the community continue to advance the water reuse industry.

Motivated by the increasing need for potable water on its campus, the University of Connecticut is in the process of implementing a sustainable program to reuse treated effluent from its wastewater treatment plant (WWTP) for non-potable uses, including feedwater for its Central Utilities Plant and turf irrigation – needs previously met using potable water. Utilizing reclaimed wastewater will make a significant portion of its potable water supply (up to 40% on a seasonal basis) available to meet UCONN’s drinking water demand.

Hazen and Sawyer performed a comprehensive study that analyzed current and future potable and non-potable water demands, and evaluated alternatives for treating WWTP effluent to meet water quality standards for industrial and irrigational reuses. Hazen and Sawyer designed a 1-mgd facility and power plant improvements (including microfiltration, reverse osmosis, ion exchange, and electrodialysis), with UV light for primary disinfection.

Several sustainable design features were incorporated, including roof stormwater capture, photovoltaic cells for power generation, heat recovery from exhaust air, and using reclaimed water as a heating source, through heat pumps. UCONN has commenced construction, despite the difficult economic climate.

The project represents the first industrial reuse application undertaken in Connecticut, and is one of only a few in New England. As such, it will be a model for other reuse projects, promoting long-term sustainability and protecting dwindling water sources. The project will ease demands placed on the Fenton River, conserving this valuable resource. It will also provide a tangible lesson to UCONN students on the importance of living sustainably.

Since our founding in 1951, Hazen and Sawyer has focused on two things: providing safe drinking water and controlling water pollution. Our range of services encompasses the planning, design, and construction management of water and wastewater-related projects – from clean water treatment, storage, and distribution to wastewater and stormwater collection, treatment, and reuse.
