Treatment Wetland Design Experts
    Unmatched in treatment wetlands expertise, Naturally Wallace Consulting (NWC) engineers work with the environment to treat unique and complex wastewater streams. With treatment wetlands and patented Forced-bed AerationTM technology at the core, we push the boundaries of "ecological engineering" to design long-term solutions that combine the science of natural systems with advanced engineering practices.

    Having taken more than 250 of the most advanced wetland systems on the planet from concept through construction and operations, NWC is the expert that incorporates scientifically proven methods and the art of design to create treatment systems that are in service across the globe.

Airport Deicing Systems
    The use of glycol- and acetate-based chemicals during airplane deicing creates a variety of environmental compliance challenges.  Deicing operations result in large quantities of contaminated runoff that is extremely variable in both flow and load.  NWC engineers have worked with facility managers at a number of airports around the world to solve this problem, including Heathrow Airport in London, and airports in Buffalo, New York and Edmonton, Alberta.

    Experience has shown that large fixed-film, attached-growth biological treatment reactors provide the most robust and cost-effective solution for treating deicing runoff.  Since no water is exposed during the treatment process, these low-profile systems can usually be built within the airfield perimeter adjacent to runways, solving the problem of land availability.  NWC has been instrumental in developing and applying this technology, which combined with our knowledge of airfield operations, allows us to optimize our solutions for airport engineers.

Oil & Gas
    Legacy contaminants associated with petroleum production and refining often result in long-term remediation challenges.  NWC has created treatment systems using ponds and wetlands for many of the international oil companies, and has been involved in the design almost every major system built by the industry over the last decade.  We have developed kinetic degradation parameters for most petroleum hydrocarbon chemicals based on pilot- and full-scale treatment systems and apply that design expertise to create innovative and environmentally-friendly treatment works for our clients.  Our knowledge of energy flows within wetland systems has allowed us to design solutions operating in conditions ranging from the tropics to the arctic.

    Mine closure often involves long-term water management issues.  NWC has been involved in the design of a number of treatment associated with old mine works.  These applications are quite diverse, and range from wetlands designed to remediate Acid Mine Drainage (AMD) from old coal works, to sulfate-reducing wetlands to remove heavy metals such as copper and nickel, and wetlands designed for cyanide removal at gold extraction facilities.

Treatment Wetlands Second Edition

This new book examines the planning, design, construction, and operation of wetlands used for water quality treatment. Co-Authored by Scott Wallace, President of Naturally Wallace, Treatment Wetlands is the first comprehensive book to systematically describe all aspects of this new technology. Topics include all major wetland configurations, wastewater sources, and combinations of climatic conditions.

This complete reference contains detailed information on wetland ecology, wetland water quality, selection of appropriate technology, design for consistent performance, construction guidance, and operational control through effective monitoring. Design approaches that can be tailored to specific wetland treatment projects are also included. Rule-of-thumb methods, regression-based empirical design approaches, and rational methods are explained facilitating wetland design based on multi-parameter input conditions.

Design manual on small-scale wetland treatment systems

As the first publication of its kind to enable wetland design with confidence intervals, Scott Wallace P.E., President of Naturally Wallace, breaks new ground with this study that incorporates data from over 1,800 small-scale wetland treatment systems.

Entitled "Feasibility, Design Criteria, and O&M Requirements for Small Scale Constructed Wetland Wastewater Treatment Systems" this design manual, funded by the Water Environment Research Foundation (WERF), represents the culmination of a 3-year research project on the use, distribution, and performance of small-scale wetland treatment systems throughout the world. The report contains over 100 original figures, diagrams, and illustrations, and was published in 2006. The book was co-published by IWA Publishing Limited and is available to all interested parties via their website.

To purchase the design manual if you are a WERF member contact the Water Environment Research Federation at www.werf.org. Non-WERF subscribers should contact IWA at www.iwapublishing.com or click here.
