Percolation & Infiltration Compliance
With new surface water compliance regulations for both SUDS and one in a hundred-year event legislation local authorities require a percolation infiltration test to ensure surface water is effectively managed.
Many local authorities require a surface water percolation test to satisfy planning conditions and building regulations on new build and alteration projects.
Our services provide a testing and solution package to ensure your project is complient with local authority requirements, our process involves, excavating test holes and checking of percolation and ground infiltration rates over a period of time using a metered water supply, the results are recorded and a report issued detailing ground porosity and soakaway suitability. Where the ground is unsuitable for direct attenuation, we can design a system to ensure surface water is managed in order to comply with the required regulations.
What we provide:
- Trial hole excavation.
- Full percolation testing complying with BRE365 standards.
- Full PDF report to assist with local authority condition or building regulation discharge.
- Design and planning of compliant soakaway design.
