This nationwide study has gathered data/information for and examined the performance of large-scale decentralized and small community wastewater systems and flows ranging from 5,000 to 50,000 gallons per day with at least five years of operating history. The study covers systems handling domestic waste flows only (residential and commercial facilities) that have been designed and constructed in accordance with regulatory requirements and accepted industry practices applicable to the particular state or region. Systems relying either on soil/land disposition or direct discharge of effluent were included in those studies. The results of the project will better enable designers, regulators and the industry as a whole to better assess and select decentralized systems used to serve certain types of facilities in various geographic settings.

Keywords: Large decentralized wastewater systems; small community wastewater systems; performance analysis and evaluation; large-scale onsite wastewater systems
