Septic tank maintenance when performed on a regular basis can reduce and even eliminate septic tank odors, septic smells and the buildup of solids leading out into the drain field potentially clogging the drain field.
Septic tank odors, especially in the winter months can be caused from a buildup of fats oils and greases collecting in low areas of the drain lines. Low areas develop over time due the settling of soil or pipes that may be improperly installed.
Dispose of fats oils and greases in garbage cans. Never use your sinks and drains as a garbage drain. Food particles will clog your system, causing septic odors, eventually make their way out to the drain field where they will convert into a bio mat restricting the leaching ability of your system.
