What Norfolk homeowners should know
Norfolk County Council is clear that private sewage systems are the property owner's responsibility — Anglian Water doesn't own or maintain them. Depending on the issue, you might also be dealing with the Environment Agency, an Internal Drainage Board, or your local council, so it's worth understanding who's who before a problem comes up.
Much of the county is flat and low-lying with a high water table, which affects how well a drainage field can disperse wastewater — it's one of the first things a specialist will check.
The Broads cover a significant area of the county, managed by their own planning authority with a status equivalent to a National Park. Work on a system within the Broads can mean different planning considerations to elsewhere in Norfolk, so it's worth checking early if your property falls inside the boundary.
Ditches and dykes are common across the county, and a septic tank discharging straight into one isn't allowed under the General Binding Rules — a survey will confirm whether that applies to your system.
What a survey covers
A septic tank survey typically includes locating the tank, checking its condition and capacity, confirming where it discharges to, and assessing whether the system meets the General Binding Rules. A thorough survey will also look at access for emptying and maintenance, and whether the system is reasonably sized for the property. You'll get a written report you can pass to solicitors or buyers.
When you need one
Here's when people usually get in touch:
- Buying a property with a septic tank, cesspit or treatment plant
- Selling one, and need to tell the buyer what you have
- Told by a surveyor, buyer or neighbour that your system may not comply
- Inherited a system and don't know its history
Typical cost
Costs vary by specialist, the size of the system and how easy it is to reach. You'll get a clear quote before any work starts.
Norfolk questions
Does the tank need emptying before the survey? + −
Often, yes. Many specialists need the tank empty to inspect it properly, and some can arrange emptying as part of the visit for an extra cost. If you know roughly how full it is, mention this when you get in touch.
What do I tell a buyer? + −
By law you need to tell a buyer in writing what the system is, where it is, and how it's maintained. A survey gives you something concrete to base that on, and who pays for any upgrade is then something you and the buyer agree between you.
Is Anglian Water responsible for my septic tank? + −
No. Norfolk County Council is clear that private sewage systems — septic tanks, treatment plants and cesspools — are the property owner's responsibility, not Anglian Water's. Depending on the problem, the Environment Agency, an Internal Drainage Board, or your local council may also be involved.
What if my property backs onto a dyke or sits within the Broads? + −
The Broads Authority is the planning authority for its area, so work on a system there can mean different planning considerations than elsewhere in Norfolk. Ditches and dykes are also common outlets for older systems, which a survey will identify.
