How to care for your septic tank system
Septic tanks need a pump-out service every three to five years to remove scum and sludge buildup.
The frequency of maintenance will depend on your system. How often you pump out also depends on the amount of water you use.
If your septic tank, long drop or grease trap gets blocked, overflows, or smells bad, it also needs a repair.
Find septic tank contractors in the
Yellow Pages website. Search for 'Septic tank services'.
Upgrade your septic tank
Upgrade your septic tank to suit your property and lifestyle, if:
- more people will live on your property
- your summer holiday home becomes your permanent residence
- you start to host a lot of visitors.
These changes put more strain on your septic tank. Maintenance alone is not sufficient.
If you live in Little Oneroa or in a West Coast lagoon catchment area, see Apply for a loan to upgrade or replace your septic tank.
