What is the expected lifespan of a septic system? We hear this question often. After all, a septic system is not only a big financial investment, but it’s something that causes much disruption when it’s not working properly.
So, what can you expect? For a conventional septic system which is properly designed, well-built, maintained as advised, and not overworked, you can expect it to last for 20 – 30 years. The next logical question is, how do you tick all of those boxes?
The first two are simple. When you purchase a septic tank from Ri-Industries, you are purchasing a properly designed and well-built tank. With over 70 years of experience in the septic tank business in Adelaide, South Australia, Ri-Industries has developed efficient manufacturing techniques to produce concrete septic tanks and septic tank lids of the highest quality that are built to last.
Our article “Common Septic Tank Mistakes to Avoid to Keep Your System Running Well” addresses proper maintenance you should follow. Fortunately, maintenance is not required often, but it should be done on a regular basis. What does that mean? The answer will be determined based upon the size and the system and amount of use it gets. Typically, pumping every 3 – 5 years is recommended.
Don’t forget about the drain field. Proper care for it will help keep the system working properly. When the drain field is not properly cared for, the wastewater cannot filter correctly, which can cause it to flow into the groundwater, or back through your pipes and into your home. Don’t build structures or park vehicles on the drain field.
Address warning signs of problems promptly. Slow draining sinks/bath, spots of healthy, green grass over the drain field, or bad odours coming from the tank or drain field are common signs of problems. Taking care of the problems early can save you money on the repairs and help extend the life of the system.
How do you avoid overworking the septic system?
- Space out laundry loads. Running numerous loads of laundry in a day can flood the field and overfill the tank, forcing untreated wastewater (with solids) into the leach field, clogging the field.
- Turn off taps when washing up, brushing your teeth, or doing dishes, to avoid running more water than necessary.
- Don’t put your drain field in a low area that collects water. Excess water seeping into the ground has the same effect as excess water from the house – a saturated drain field that functions poorly and may fail early.
- Consider low-flow shower heads and water conserving toilets to reduce the amount of water flowing through the system.
- Be careful what you flush. Our article “Can I Flush This Waste?” has important tips.
