Advanced Design of Onsite Wastewater Systems

NOWRA has introduced a training curriculum for the design of advanced onsite wastewater treatment systems. This curriculum was requested by MOWPA -- Maryland Onsite Wastewater Professionals Association -- to help designers in that state comply with new and more stringent requirements for the use of Onsite Systems mandated by the state to comply with Chesapeake Bay cleanup requirements. A summary of the training documents is attached. Although each state's requirements differ to some degree, NOWRA is able to adapt this curriculum to fit those requirements.

In addition, in September 2013, NOWRA's Board of Directors approved a Standard of Practice for Decentralized Wastewater Treatment -- Soil-Based Treatment System "Selection and Design". NOWRA is working across the industry to provide detail for each of the elements identified in the Standard of Practice. You can review the Standard of Practice by clicking here.
