It is proposed that the storage capacity of both tanks be incorporated into a single new tank of the same diameter as the existing Tank 4A. Replacing these tanks at this time prevents the need to revisit the site with new disturbing activities in a few years. The base of the new tank will be at the same elevation as the existing Tank 4A, and the new tank is anticipated to be approx. 40 feet high to match operating elevations from District's Tank 1 and 4 which is being removed. Tank 1 is on the same pressure gradient. The capacity of the new tank will be approx. 870,000 gallons.
