Divide the total soil treatment area into at least four <br />equal parts connected serially. <br /> <br /> f. Flood prone areas <br /> <br /> 1. No part of a system shall be installed in the floodway. <br /> <br /> 2. The soil absorption system shall be located on the <br />highest feasible area of the lot and shall have location <br />preferences over all other improvements except the <br />water supply well. The soil absorption system shall not <br />be installed in the floodway. <br /> <br /> 3. If a pumping station is used to move effluent from the <br />sewage tank to the drain field, provisions shall be <br />made to prevent the pump from operating when <br />inundated with flood waters. <br /> <br /> 4. The building sewer shall be designed to prevent back <br />flow of liquid into the building when the system is <br />inundated.
