Councils recommend that septic tanks should be pumped out when the sludge level reaches 30%. Contact Lee’s Environmental to book a free test of your septic tank when we are on your property performing other services.
Alternatively, calculate approximately when your septic system needs pumping out with the following frequency guidelines. Please note that the frequency of pump out can vary greatly depending if people are home more or less frequently, and by what cleaning products and other materials are flushed down the toilet.
3 Months – 10+ people
6 Months – 8-9 People
1-2 Yearly – 6-7 People
2-3 Yearly – 4-5 People
3-4 Yearly – 2-3 People
5-6 Yearly – 1 Person
