Optional Pre-Conference Workshop
Subsurface Drip for Decentralized Wastewater Dispersal: Installation, Operation and Maintenance; Best Practices Workshop
Sunday, October 22, 2023 from 12:00 PM to 5:00 PM. Separate registration required.
Subsurface Drip has become an increasingly popular method for the final treatment and dispersal of wastewater effluent in land-based decentralized wastewater systems. Modern drip technology was originally developed in Israel to support agricultural production, while greatly reducing consumption of water. Subsurface drip’s use with wastewater systems has been developing throughout the United States since the early 1990s, based upon its ability to optimally utilize the receiving landscape under a variety topographic and soil conditions, its relative ease of installation, and its ability to minimize effluent impacts groundwater and surface waters.
There are several unique considerations that must be addressed to assure any particular drip application will be a sustainable wastewater management system for the facility or community served. This Best Practices workshop is being developed by NOWRA’s Technical Practices Committee, who are recognized experts in the field.
Topics to be covered include:
- Unique elements of soil and site assessment and wastewater characterization for drip systems.
- Considerations and importance of integrated system components
- Recommended installation techniques for varying terrains and soil conditions.
- Start-up/On-boarding procedures.
- Filter options, idiosyncrasies, and their life-cycle maintenance needs.
- Field dosing and flushing considerations and options.
- Dripfield hydraulic performance monitoring, operation and maintenance.
- Overall system O&M.
The Workshop focus will be on decentralized systems (multi-family, small community, commercial) beyond “single-family”, although topics covered would also have relevancy to smaller residential systems.
