Why it matters
Regular servicing
isn't optional — it's
how it lasts
Private wastewater systems are out of sight and easy to forget about — until something goes wrong. A septic tank that isn't emptied regularly fails prematurely. A treatment plant that isn't serviced drops below the effluent quality required by its EA permit. Both problems are expensive. Both are avoidable.
A service contract with ClearFlow means the system stays on top of the schedule, not you. We log your system details, set the reminders, arrange the visits, and provide written service records after each one. You get the paperwork you need for compliance — and peace of mind that the system is being looked after properly.

Drainage field observation where accessible
-
Written service record and findings

How often
How often does
yours need emptying?
12 Months
Septic Tank
Most domestic septic tanks should be desludged every 12 months. A larger household or smaller tank may need it more frequently — we'll advise at the first visit.
12–24 Months
Treatment Plant
Sewage treatment plants typically need desludging every 12–24 months depending on system size and the number of people using it. Annual servicing will flag when a desludge is needed.
6-12 Months
Commercial / High Use
An existing field that's been overloaded — through an undersized tank or years without emptying — may be beyond recovery. We assess the existing field honestly and tell you whether it can be reused or needs replacing.
