Dug wells that are 21 feet or less in depth shall be sealed with grout from land surface to within three feet of the bottom of the well. Dug wells greater than 21 feet in depth shall be sealed with grout from land surface to a depth of at least 18 feet below land surface. In all cases a watertight surface curbing shall extend from a minimum of 12 inches above land surface and continue the entire length of the sealed interval. Open wells, sometimes called sumps, which exceed ten feet in average diameter and are dug to a depth of ten feet or less are exempt from these construction requirements, but are subject to all the requirements covering the use of ground water (water right application). (See Figure 210-13).
