Local knowledge
Private drainage around Masham
Farmsteads, cottages and holiday lets around Masham are often on septic tanks, and some systems serve several properties at once. Sloping ground and stone underfoot in places can make drainage field design tricky, so a percolation test matters.
We cover Healey, Fearby, Grewelthorpe, Kirkby Malzeard, West Tanfield and Thornton Watlass and the countryside around them. Every job starts with an assessment of the whole system and, where needed, a percolation test.

Questions from Masham
Do you cover villages around Masham?
Yes, including Healey, Fearby, Grewelthorpe, Kirkby Malzeard, West Tanfield and Thornton Watlass. Send your postcode and we'll confirm.
Can one septic tank serve a farmhouse and holiday cottages near Masham?
Often, if it's sized for everyone it serves at peak occupancy. Discharges to the ground are limited to 2 cubic metres a day under the general binding rules; above that a permit is needed.
Do I need permission to replace a septic tank in Masham?
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.
