Why engineered wetlands? Engineered wetlands greatly advance the treatment capacity of wetland treatment systems and enable a simple, low cost alternative to challenging wastewater and water problems. Unlike earlier generations of passive constructed wetlands, engineered wetlands boost treatment performance through the use of aeration or recirculation. Previously, applications requiring nitrification of wastewater could not use treatment wetlands. Now, engineered wetlands provide reliable and cost effective nitrogen removal. The large size of passive wetland treatment system often prevents their use. Engineered wetlands systems can cut the treatment area by 50% or more, opening up many more sites to wetland treatment. Treatment time is faster in engineered wetlands than passive systems, which also reduces the treatment area requirements. JW NAWE strives to design long-term, sustainable treatment systems and we are constantly adapting to maintain our reputation for innovation and leadership in the decentralized wastewater field. Our Research and Development (R&D) efforts continually focus on increasing efficiency and treatment performance of our designs. Through our partnership with the wastewater/water operations company EcoCheck, Inc. we have initiated an expanded R&D effort to further establish our Full-Circle Engineering services. The Full-Circle Engineering concept is based on our notion that quality engineering and operational services require open communication between engineers, construction crews, and system operators. Engineering design and operation can be improved through regular feedback and communication between engineers and operators. As part of our commitment to Full Circle Engineering, JW NAWE conducts ongoing research into the performance of alternative wastewater systems. Our full report (2006 Compliance Alt WW Facilities. PDF) looks at the compliance of 74 alternative wastewater systems in Minnesota, designed by 8 engineering firms. This report clearly shows the correlation between system ownership, operations and maintenance and compliance.
