How to do the daily maintenance of septic system?
How a septic tank works
In cities near Boston, the municipality usually builds a unified sewage treatment system, but in some good school districts (such as Carlisle, Concord, Wayland) that are far away, due to the scattered housing, the municipality generally does not do this. The deep sewage well is the septic tank. At the top of the pool about 20 cm from the ground, underground pipes leading to the grass in all directions are laid. There are many small holes on the pipes. Special fermentation bacteria are placed in the pool. All excrement and waste water are fermented in the pool, the solid part is greatly reduced, and the treated liquid becomes a liquid close to clear water. In this way, it not only "digests" the sewage, but also plays the role of irrigating the grassland.
Routine maintenance of a septic tank includes:
1. Know the specific location of the septic tank in the house, and it is best to prepare a schematic diagram. Some clients have moved to Massachusetts from a foreign country or other state without understanding the situation. It is recommended to find out before the transfer of the property. Former homeowners who don't have a schematic can also ask when the last cleanup was done and which company was used, as companies usually keep information about customers.
2. Ask a professional company to clean the septic tank every one/two years, or depending on your own situation.
3. Keep all records of maintenance, cleaning and inspection.
4. Develop a good habit of saving water and repair leaking faucets and toilets in time, because excessive water flowing into the pool in a short time will destroy the function of the septic tank to purify sewage.
Things to avoid on a daily basis include:
1. Except for grass, do not plant any trees near septic tanks and pipes, as tree roots can damage the pipe system.
2. Do not pour the broth of the boiled meat directly into the sewer, to avoid the solidified solid oil remaining on the pipe wall, which will affect the normal operation of the sewage system.
3. The water softener uses salt to remove hard water with excessive hardness, but some studies have shown that too much salt entering the septic tank will affect the fermentation function of the bacteria in the tank.
4. When shopping, do not buy toilet paper that is not marked with the words "septic tank safe use", and do not throw small-sized domestic waste into the toilet. In addition, cleaning products also try to avoid using products containing antibiotics to prevent the destruction of active bacteria.
