FAQ
Q: How often does a septic tank need emptying?
A: As a rule, once a year for the average household. It depends on the size of the septic tank and how many people are using it. Two years is possible, depending on the size of the septic tank. If the frequency is more than once a year, it is usually because a soakaway has failed and that shouldn’t be happening. Check out this table about the pros and cons of septic tanks. Frequent emptying can be quite expensive.
Q: Are there septic tanks that don’t need emptying?
A. No. All septic tanks should be emptied to protect the soakaway!
Read the section about septic tank emptying on our Septic Tank and Soakaway Problems page for more information.
Q: What size should a soakaway be?
A: That depends on the nature of the water percolation test. Rainwater at 5 ppm? Treated effluent from a sewage unit at 20 ppm? Or effluent from a septic tank at 100 ppm?
Q: Do I need building regs for a soakaway?
A: Yes
A: Soakaways from Septic tanks are bound to get blocked. Raw sewage has 300 parts per million (ppm). Water from a septic tank is not much better at 200 ppm. So those fine particles start to block the soakaway and the ground below and around the soakaway pipes from day one!
Q: Do soakaways need maintenance?
A: It is very hard to maintain a soakaway. Like all filters, they block!
