The tank should have an <br />end-screen or valve flap to <br />prevent insects, birds or other <br />wildlife from entering the tank. <br />The existing screen was damaged <br />and should be replaced. The <br />overflow pipe did have an air <br />break to eliminate the possibility <br />of storm water backing up into <br />the tank in an extreme flood. The <br />tank vent was properly screened. <br /> <br /> <br />Elevated Water Storage Tank <br />City of Arden Hills South Tank <br /> <br />12 <br /> <br />Photograph 20 - Overflow Pipe <br />Outlet <br />
