Site Testing
Site Suitability Assessment (Percolation Test)
A Site Suitability Assessment or Percolation Test is required for planning permissions for all proposed new developments which do not have access to public mains. A Percolation Test and Site Assessment is essentially an analysis of your site; the hydraulic properties of your soil and the height of the water table on your site, in order to determine what type of wastewater treatment system and percolation area would be most suitable to deal with your household wastewater.
The waste system design consists of a Wastewater Treatment System (septic tank, packages treatment system, peat filters, wetlands) and percolation area. Proper testing, system selection and percolation design minimise the risk of contamination of our water resources and malfunction of your system. A positive Site Assessment result and detailed on site treatment drawings are the first positive step towards a successful planning application decision.
At LJA the testing procedure will be carried out by our Engineers who has completed the FAS/FETAC “Site Suitability On-site Wastewater Treatment” Certificate. The test is carried out in accordance with the EPA 2009 Code of Practice.
We carry full Professional Indemnity Insurance as required by the County Council.
BRE Infiltration Testing
Local Authorities now require planning permission applicants to account for the disposal of surface water generated by their proposed development. LJA can present the required information for our clients by submitting a BRE Digest 365 infiltration test and SUD’s (Sustainable Drainage Systems) design proposal with the planning submission for both residential and commercial developments.
A BRE Digest 365 infiltration test is carried out to determine the infiltration rate and ultimately the design capacity of a proposed rainwater soak away system.
We can provide both tests as a standalone service. If you are using another Architect or Engineer, we will work in conjunction with your Architect or Engineer to provide you with a Site Assessment or BRE Test.
