What do you know about your Septic Tank System?

A septic tank system refers to any kind of on-site sewage management system including traditional septic tanks, pump-outs, composting toilets, secondary and tertiary treatment systems as well as sand and fabric filters.

Just like your car and other belongings, your septic tank system is important in the daily functioning of your household. This booklet has been written by NZ Water & Wastes Association and the Ministry for the Environment for you, a septic tank system owner, so that you can learn how to keep your septic tank system happy.

Maintenance of your Septic Tank System

Just as your car requires regular maintenance, so does your septic tank system. As a general rule, your septic tank should be inspected annually and pumped out every 3-5 years or more often if necessary.

Your land application system generally won’t need any maintenance except a quick check that there are no soggy areas. Remember when choosing a contractor to empty your septic tank, always ensure you employ a code compliant contractor.
