Pictured above is one of our latest septic system installs in Norton, MA. This system consisted of two septic tanks instead of the just one. The second tank acts as the pump chamber that pumps the effluent up hill to the leaching field. The pump chamber is needed when there is a high water table and the leaching field has to be installed higher than the plumbing that exists the house. This configuration is common in Norton and the surrounding towns.
