The Commercial PED system: Sustainable discharge of treated effluent
Silver Hill Duck – discharging effluent sustainably
The PED system pilot project and project expansion
Silver Hill Duck wanted to run a pilot project for dispersing effluent on a small patch of land of approximately 1.6 hectares. If this was successful, the system would be extended. The EPA had given Silver Hill Duck an effluent release licence of 480 m3 per day across 14.6 ha.
Silver Hill Duck decided to opt for a subsurface dripline system to disperse the effluent. Bosta were asked to quote a turn-key pilot solution, from connection to a tank at the processing factory all the way to the driplines, including soil moisture probes. The system had to be remotely controllable, enable the reuse of water for irrigation purposes and should continue to meet the requirements set by the licensing committee for the next fifteen years.
Bosta designed a system for approximately 14.6 ha, with a proposed pilot project area of 1.6 ha, and in 2021, Bosta executed the pilot project by installing a Precision Effluent Dispersal (PED) system.
Phase 1 of the project met all objectives that were laid out by the EPA for the drip irrigation pilot scheme. This allowed the full project to commence, with installation by Bosta in July 2023.
Silver Hill Duck now no longer discharge treated effluent to the stream and are in compliance with the EPA licence.
Bosta's solution: The PED system
PED – bespoke turnkey solution
A solution in the form of a system that filters the substances contained in wastewater, thereby reducing them to acceptable levels in relation to both the ecosystem and legal standards, and simultaneously enables reuse of the water.
Custom designed system
Suitable for other applications
The PED system is suitable for implementation in other sectors such as residential developments. It has already been installed in an egg production facility, and at a campsite, where wastewater from toilets is purified and reused.
