Eastern Sierra Community Service District CY2022 Disaster Water Grants Program

The proposed project would include the following components: rehabilitation of approximately 32,411 feet of existing sewer main pipeline using a new flexible cured-in-place pipe (CIPP) lining to significantly reduce groundwater infiltration and extend the life of the aging infrastructure (see Table 1); installation of new seals using spray or epoxy coating cured by an air-dry system for 94 manholes to prevent stormwater inflow and further protect the system during future flood events, steam or ultraviolet light may be used as alternative curing methods on an as-needed basis, but use of these methods is generally not anticipated; and development of temporary groundwater dewatering wells as needed in areas where high groundwater table exists and could impede construction activities.
