Perimeter footing drains are required. A 4 inch perforated PVC drain line at footing elevation shall be
installed and tightlined to daylight. Free draining backfill, such as pea gravel or drain rock, shall envelope
the PVC drain line and be placed adjacent to the tank to ground surface elevation

adjacent to the pump well. A valve or other suitable device for opening the gravity drain shall be located as
to be accessible from ground elevation.
10. All inlets, vents, and drains shall be screened, trapped, or otherwise protected to preclude introduction of
contaminants into the cistern. The hatch shall be made watertight, to prevent entry of contaminants and
locking to prevent entry by children. A raised lip around the hatch is highly recommended for exclusion of
contaminants.
