Pumped Percolation Systems for polishing filters
We supply customised pipework and components for pressurised infiltration systems for sand and soil filters for commercial systems and single houses. Based on site details provided, we calculate site specific designs with pump capacity, pipe and orifice dimensions.
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 if required by your County Council.
We provide project management of larger commercial systems.
Our designs are based on site and soil details with filter dimensions supplied to us. We supply proposals for the pipe network system with calculated design details including pump and dose requirements based on pipe diameters, orifice size and spacing. Design proposals are based on the US EPA Wastewater Design Manual 2002 and the Irish EPA Code of Practice 2009*. We provide certificates of compliance to meet the requirements of new Building Regulations SI 9 2007-2014.
Pressure distribution using uPVC pipes is a more efficient method of distributing effluent onto sand and soil polishing filters than gravity and so is permitted a considerably smaller area in the regulations. As a result it is very important that they are designed and operate properly.
Pumped low pressure uPVC pipe systems are used with sand filters, mounds and polishing filters as the perforated pipe network that spreads the water evenly over the soil or sand infiltration area. To operate effectively they should be configured so that the water is distributed as evenly as possible with water pressure in each pipe and existing to the ends of all the pipe lengths. This is similar to designing a home hot water radiator heating system and must be customised to each site. Too many holes (orifices) or too many pipes will result in poor effluent distribution often with overloaded areas and soggy wet areas.
