Looking after septic systems and tank water on South Gippsland properties

Know your system

Find out where the septic tank, its lids and the absorption trenches or irrigation area are, and mark them so vehicles stay off. Know where the tank outlet valve and pump switch are so you can isolate water quickly.

What goes down the drain

Septic tanks rely on bacteria. Bleach in large amounts, fats, wipes, sanitary products and coffee grounds upset the balance or block outlets. Spread washing over the week so trenches are not flooded on one day.

Pump-outs and checks

Sludge builds up in the tank over the years. A check every few years shows when it needs pumping. Aerated treatment systems need servicing by an accredited agent on the schedule set in their permit.

Clean water from the roof

Keep gutters clear, fit leaf guards and a first-flush diverter, and keep tank inlets screened against mosquitoes and animals. A filter or UV unit adds protection for drinking water.

Keeping the pump healthy

Do not let the tank run dry; a pump that loses prime can overheat. Listen for a pump that starts and stops when nothing is on, which usually means a leak or a failing pressure switch.

Winter and summer

Wet winters can saturate trenches, and dry summers can empty tanks. Conserve water when tanks are low, and if the septic backs up in wet weather, reduce water use and call for advice.
