Septic tank emptying and servicing planner

How the planner works

Tell it what kind of system you have, when it was last emptied (and, for a treatment plant, last serviced) and how often it should be done. It works out the next dates and builds a calendar file you can add to your phone or computer, with a reminder before each one.

The planner never fills in how often for you. Tanks and plants differ, so the interval has to come from the manufacturer's manual for your model or from your emptying or maintenance company. If you don't have the manual, ask them, and keep their answer in writing.

What the official guidance says

For England, the Environment Agency's general binding rules guidance covers when sludge must be removed. Our guide to getting your septic tank emptied explains what it says. Wales, Scotland and Northern Ireland have their own regulators, so check theirs for a property there.

After each visit

Update the dates in the planner and download the calendar file again. Keep the receipt from the emptying company, with its waste carrier details, and write the date on your system card. Your dates are kept in this browser on this device and are never sent anywhere.
