Lake lots
What should Chickamauga Lake homeowners know?
Many Harrison and Ooltewah lake lots slope down to the water, with the drain field uphill and a pump moving effluent to it. Near the shoreline the water table can be high. That makes pump and alarm checks, and careful planning for any repair, especially important. See Harrison septic service.
