Regularly maintaining a properly sized septic system, using water moderately, and taking care about what you dispose can help protect water sources. Signs of a malfunctioning septic system include toilets, showers and sinks that take a long time to drain, occasional sewage odours, and grass over the system that is unusually green or spongy. If you notice these signs, contact a licensed contractor. Some examples of what should not be flushed or poured down the drain include:

1. Medications;
2. Diapers;
3. Feminine hygiene products;
4. Grease, and chemicals, such as paints, solvents, thinners and other household compounds not intended for down-the-drain use;
5. Kitty litter;
6. Coffee grounds;
7. Cigarette butts;
8. Photographic solutions;
9. Pesticides or herbicides.

If a product does not break down naturally, do not flush it into your septic tank. If you question whether the septic system can handle it, do not put it in the toilet or down the drain either, but dispose of it appropriately. Other tips:

1. Septic tanks accumulate solid material that must be pumped out. Have a licensed contractor inspect your septic system every two years, pumping out the solids when required.
2. Properly size your septic system. If you install additional water uses, such as toilets or showers, the septic system may need to be upgraded.
3. Keep a good cover of grass over the tile bed to take up excess nutrients and water.
4. Divert storm and drainage water away from the septic system.
5. Do not allow cars, trucks or any other equipment around the tile bed as the wheels may crush it and ruts may alter the drainage patterns.
