Local knowledge
Private drainage around York
Beyond the ring road, farmhouses, cottages and barn conversions often rely on private drainage, some of it decades old. Low-lying land near the Ouse, the Foss and the Derwent can have a high water table and heavy clay, which affects where a drainage field can go and how big it needs to be.
We cover Naburn, Elvington, Wheldrake, Askham Richard, Skelton and Stockton-on-the-Forest and the countryside around them. Every job starts with an assessment of the whole system and, where needed, a percolation test.

Questions
Questions from York
Do you cover villages around York?
Yes, including Naburn, Elvington, Wheldrake, Askham Richard, Skelton and Stockton-on-the-Forest. Send your postcode and we'll confirm.
Does a high water table affect septic tanks around York?
It can. A drainage field needs unsaturated ground beneath it to treat effluent properly, so on wet, low-lying land the field may need to be larger, raised, or replaced by a treatment plant with a different outlet. A percolation test and a look at the ground in winter help decide.
Do I need permission to replace a septic tank in York?
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.
