"I just wanted to say thank you for sending the very informative pamphlet on septic maintenance, as well as accommodating us this last weekend with emptying our septic tank on a SATURDAY.  My husband and I really appreciated your service... I only wish I knew of your company earlier.  However, now I do, and will call on you for future services.  If anyone asks me for a septic company, Mother Lode is who I will refer."

When you have a septic system, you are the owner of the sewer treatment plant on your property. It is very important that you know where it is and develop a maintenance plan.

The #1 thing to know about your septic system is "Where is it?" The septic tank is the heart of the septic system. Tanks should be opened, checked, and pumped at least every 3-5 years to ensure that roots are not gaining a foothold and that the inlet/outlet lines are functioning properly.

Did you know that as solids build up, they filter through from the solid side into the effluent side of the septic tank? They then fill the tank with sludgy solids which will eventually filter through into the leach lines. When this occurs, the system will continue to work for a period of time; however when large amounts of sludge solids are passed out to the field, they will cause pre-mature system failure.

Q: How often should my septic tank be pumped?
A: On average, a septic tank should be pumped every 3-5 years, depending on the condition of the septic system and the volume of usage.

Q: I have a running toilet in my house, does this affect my septic system?
A: YES! Running toilets are notorious culprits for causing septic system problems. Check your toilet(s) regularly for leaks.
