NAWE has extensive experience in designing simple, low-cost, ecological systems to drive specific treatment reactions for our industrial clients. Our engineered wetland systems, in-situ phyto- and bioremediation systems and engineered soil-matrix biofilters help our customers achieve exceptional business and environmental results. NAWE's industrial clients fall into the following sectors.
Water Reuse
Water reclamation and reuse have become increasingly attractive options for water conservation and effluent disposal. Water reuse eliminates surface water discharges, improves water quality, and reduces irrigation and other non-potable demands on potable water supplies. NAWE stands out in the design of reuse projects because of our expertise in both wastewater treatment and subsurface dispersal systems. More importantly, NAWE is experienced in implementing reuse on a manageable scale. We specialize in reuse technologies for projects both large and small.
NAWE has engineered systems that collect and treat wastewater for reuse in a number of different applications. NAWE's broad experience in wastewater permitting coupled with the technical knowledge of soil adsorption systems make the efforts successful. Reuse of wastewater is becoming more common, particularly as the methods and permitting become established. NAWE's experience and knowledge in designing projects that are innovative in the field of wastewater treatment and disposal provides a strong foundation for confidently developing reuse projects.
British Petroleum (Casper, Wyoming)
The wetland system designed by NAWE for British Petroleum in Casper, Wyoming can handle flows up to 3 million gallons of BTEX and MTBE-contaminated groundwater per day. NAWE’s wetland treatment system is incorporated into a premier Robert Trent Jones golf course and the treated wastewater is used for irrigating the course. NAWE’s expertise in water reuse has turned an unusable brownfield into a valuable community amenity that will be able to operate for over 100 years with low operations and maintenance (O&M) costs.
The NAWE British Petroleum project was awarded the distinguished "Grand Award" from the American Council of Engineering Companies (ACEC) and winner of the 2005 "7 Wonders of Engineering Award" from Minnesota Society of Professional Engineering (MSPE).
The Ponds (Oak Grove, Minnesota)
This wastewater system consists of a vertical flow wetland followed by a sand filter for polishing to serve 223 residential units of The Ponds development. The treatment system is equipped with a reclaim pond that stores treated effluent for reuse on an adjacent 18-hole golf course. The entire facility infrastructure fits on less than 1.5 acres of land.
MMPA (Fairbault, Minnesota)
Minnesota Municipal Power Agency's (MMPA) Faribault Energy Park wanted to reuse cooling water and collect stormwater runoff to reduce withdrawals from the Jordan Aquifer. The agency also wanted to create a natural park setting to provide an amenity in the community for visitors. NAWE partnered with civil engineers and landscape architects to create a working landscape. The resulting wetland park system will provide stormwater treatment, storage and blending with high salt content water from the cooling towers. The wetland park system will be beneficial to both the surrounding community and environment. The reuse of cooling tower blowdown in combination with stormwater collection will reduce draws on the Jordan Aquifer and limit the discharge of salty water into the adjacent ditch.
