Decentralized High Strength Waste Facility Design Recommendations and Best Practices
By By Dennis Hallahan, P.E.
High strength waste (HSW) presents a challenge for any type of onsite wastewater treatment system. This is apparent in restaurant facilities, where the design life of the system is significantly less than a typical residential system. It can also be a factor in other types of businesses that generate HSW. Each facility type will have unique wastewater characteristics as well as unique site and soil conditions for the system designer to consider. The more information the designer can obtain in advance via effluent sampling, water meter records, usage patterns about the distinct, and potentially problematic conditions, the better the proposed design.
