Since January 2020, a septic tank that discharges to surface water — a ditch, stream or river — must be replaced or upgraded. Non-compliance can bring enforcement and routinely holds up or reduces a house sale once a buyer survey flags it.
Sort it before it holds up a sale
A buyer survey or conveyancer will usually check the drainage. Resolving compliance early avoids a delayed sale or a last-minute upgrade bill.

What's involved
Septic Tank Compliance
A septic tank discharging to a watercourse must now be replaced or upgraded; discharging to a drainage field is still allowed.
A specialist assesses your system against the 2020 General Binding Rules and gives a clear verdict.
Usually a new drainage field so it no longer discharges to surface water, or a sewage treatment plant.
FAQs
Septic Tank Compliance questions
What are the 2020 General Binding Rules?
Since January 2020, septic tanks that discharge directly to a watercourse must be replaced or upgraded, typically to a drainage field or a sewage treatment plant. Tanks discharging to a compliant drainage field are generally unaffected.
Does non-compliance affect selling my house?
Yes. A non-compliant septic tank can delay the sale, reduce the price, or require you to fund an upgrade before completion.
