Cesspools are constructed from cylinder block. Cesspools drain the liquids and septic tanks catch the solids.
We recommend cleaning your cesspool every 5 years. If a septic tank is not cleaned out every 2 years, it allows solids to flow into the cesspool or leach field, which causes damage that costs from $30,000 and $50,000 to repair.
This tank holds all the left over water from your washing machine. Grey tanks are strictly used for washing machines. Because the soap in the tank kills the beneficial bacteria it should be cleaned out every 1 to 2 years depending on usage.
