Septic tanks need consistent care to keep them active and healthy. Although commercial septic tank activator can be purchased at the store, it's simple and inexpensive to make a homemade septic tank activator. The activator, which is made up of yeast, brown sugar and water, keeps the bacteria in the tank working to eliminate the waste.

  1. 1

    Pour two pouches of active dry yeast and a pound of brown sugar into a large mixing bowl. Use a potato masher to gently break up lumps and mix the two ingredients.

  2. 2

    Pour 4 cups of warm water into the mixing bowl and stir the mixture with a wooden spoon until the sugar has completely dissolved.

  3. 3

    Place the bowl in a warm place and let it sit for about 20 minutes. The mixture will become foamy and expand, so make sure it has ample room in the bowl.

  4. 4

    Pour the septic tank activator into the toilet and flush.

  5. 5

    Repeat treatment every three to six months, or more frequently if experiencing some blockages.
