Local knowledge
Private drainage around Northallerton
Outside the town, farmhouses, cottages and barn conversions across the flat, fertile Vale often rely on septic tanks or treatment plants, many of them decades old. Field ditches and becks feeding the River Wiske are common outlets for older systems, and those that are septic tanks discharging straight to a watercourse need bringing up to the current rules.
We cover Brompton, Romanby, Thornton-le-Beans, Osmotherley and the villages along the A684 and the countryside around them. Every job starts with an assessment of the whole system and, where needed, a percolation test.
