Residential 
 

Outside of metropolitan areas, residential developers are blazing the trail with smart growth developments. Without the ability to connect to municipal or city sewer, residential developments and industrial parks are looking towards innovative methods to collect, treat and dispose of wastewater. By implementing smart growth and conservation design into community development projects, developers and government leaders can create a greater sense of community while preserving open space and maintaining natural wildlife habitat.

In Minnesota, decentralized wastewater systems have become more and more popular for residential developers. The Minnesota Pollution Control Agency has permitted over 100 new wastewater systems since 2005 with over 60% of permits for new decentralized wastewater systems.

When a decentralized wastewater system is constructed, the developer is initially accountable for ensuring responsible management of the water and wastewater system; however, once the development nears completion, that responsibility is transferred over to a homeowners association, utility or local governmental unit.

Decentralized wastewater management enables the ability to create communities outside of sewered metropolitan areas and opens up the creative possibilities for implementing smart growth concepts. Smart growth places homes in clusters, creating neighborhoods that can be efficiently served by electricity, gas, telephone, sewer, water and other utilities cutting down on initial infrastructure costs. This conservation design practice establishes orderly developments that preserve the integrity of our natural resources by not chopping up tracts of land in cookie cutter large acreage lots.

As a member of the Sustainable Land Use Coalition, and U.S. Green Building Council, JW NAWE has worked with many communities and developers to provide decentralized wastewater management that opens up the creative possibilities for implementing smart growth concepts.

JW NAWE is a leader in decentralized wastewater management and has been involved in a number of award winning open space development projects.

Jackson Meadow (Marine on St. Croix, Minnesota)
JW NAWE was responsible for the design and permitting of two subsurface flow wetland treatment systems as an alternative to conventional onsite septic systems for 64 homes for the Jackson Meadow development. This project won the 2000 Minnesota Honor Award from the American Institute of Architects and the 2002 Minnesota Environmental Initiative Award.

Fields of St. Croix (Lake Elmo, Minnesota)
Fields of St. Croix wastewater system consists of a subsurface flow wetland treatment system as an alternative to conventional onsite septic systems for the 46-home development. This was the first large-scale constructed wetland treatment system permitted by the Minnesota Pollution Control Agency. The developer, Robert Engstrom Companies, won the 1998 Minnesota Environmental Initiative Award for this project.

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.

Comprehensive Services
The operation and maintenance of community wastewater systems is a hot issue amongst regulators, land developers, and design professionals. There is a growing need for local government, developers and communities to understand the management, operation, and maintenance needs of decentralized wastewater treatment systems.

What does it mean to manage, operate, and maintain a wastewater treatment system? Wastewater treatment systems require regular operational checks by a qualified professional who can also help plan for future maintenance of the treatment system. All wastewater treatment systems require routine monitoring, operational adjustments, replacement of worn parts, and fiscal management. Without proper operations and maintenance (O&M), any wastewater system - big or small - will prematurely fail and result in environmental degradation and potential human health risks.

Through our partnership with EcoCheck, Inc., JW NAWE has expanded its services to include O&M services for public and private wastewater and water systems. Creating continuity between engineering design, construction, and system operation makes for robust, high-quality systems that last. We are continually improving our engineering designs through the feedback gained from our construction crews and system operators.
