AshTech - Low Pressure Pipe Systems
We provide complete low pressure pipe (LPP) systems for commercial systems down to single house systems. Pressure distribution using PVC pipes is a more efficient method than gravity of distributing effluent onto sand and soil polishing filters (mounds and sub-surface systems) and so requires a considerably smaller area.
We can arrange installation or oversight of the pipe network, with certification of the system and suitability of pump and pump dosing arrangements. Our suggested designs are based on the US EPA design manual and on the Irish Environmental Protection Agency (EPA) Code pf Practice 2009. (The EPA has confirmed that site specific designs are required for each site and the design specification in the 2009 Code of Practice is one example.) The 2009 CoP is being revised to include in-ground LPP systems in addition to the existing “bed” and “mound” systems.
- Packaged systems for small and large systems
- Simple assembly and installation.
- Less land area compared to a gravity system
- Pipes are rigid PVC so no coiling or bending
- Pre-drilled holes so no drilling at the site.
- 90 degree turn-ups allow cleaning access.
- Ball valves at ends of each lateral allows for flushing of solids maintenance to ensure a long system life and no costly filter replacements.
- Ball valves at the start of each lateral allow flow control and better pressurisation.
- Pressure right to the end of each lateral.
- All components are included and pipes cut ready for on-site assembly with PVC solvent.
- Installation guidelines with photos of typical installed systems are available.
- Peace of mind during system compliance sign-off.
