Local knowledge
Private drainage around Selby
The Selby district is low-lying and flat, with the Ouse, the Aire and the Derwent running through it. Parts of it lie in flood zones and have high water tables, so drainage fields need careful design, and treatment plants are often the more reliable choice.
We cover Cawood, Riccall, Hemingbrough, Kelfield, Camblesforth and Drax and the countryside around them. Every job starts with an assessment of the whole system and, where needed, a percolation test.

Questions
Questions from Selby
Do you cover villages around Selby?
Yes, including Cawood, Riccall, Hemingbrough, Kelfield, Camblesforth and Drax. Send your postcode and we'll confirm.
Is a treatment plant better than a septic tank in the Selby area?
Often, on low-lying ground. A treatment plant cleans the water to a higher standard, so it may need a smaller drainage field, which helps where the water table is high. The assessment will show what suits your site.
Do I need permission to replace a septic tank in Selby?
A new or replacement system normally needs Building Regulations approval, and planning permission can apply in some cases. If it can't meet the general binding rules, an environmental permit may be needed.
