Percolation Tests carries out BRE365 soakaway testing and foul effluent infiltration testing across Worcestershire, supporting planning applications, self-builds, and developments throughout the county.
Ground conditions in Worcestershire
Worcestershire’s geology varies significantly across the county, which has a direct impact on percolation rates. The Severn and Avon Vales are dominated by heavy clay and marl deposits, which typically drain slowly and often require larger soakaway crates or, in some cases, an alternative drainage strategy. Around Bromsgrove and the Lickey Hills, sandstone and gravel deposits generally percolate far more readily. Because of this variation, a site-specific test is essential rather than relying on assumptions from a neighbouring plot — even properties a short distance apart can return very different infiltration rates.
What we test for
- BRE365 percolation testing for surface water soakaway design (SuDS)
- Foul effluent infiltration testing under Part H of the Building Regulations for septic tank and treatment plant drainage fields
- Drainage strategy support, working alongside civil engineering partners
Coverage across Worcestershire
We regularly carry out testing across Worcester, Redditch, Bromsgrove, Kidderminster, Droitwich Spa, Evesham, Malvern, Pershore, and the surrounding villages and rural developments. We can typically attend site within a short timeframe of enquiry.
Why get a percolation test
Most local planning authorities in Worcestershire will require BRE365 percolation test results before discharging a drainage-related planning condition, particularly for self-builds and small developments not connecting to mains surface water drainage. Getting this done early avoids delays further down the line in your build programme.
