About This Project

The Soboba Band of Luiseño Indians are a sovereign nation located in the northeast corner of the San Jacinto Valley. The Tribe owns and operates the growing Soboba Casino and looked to expand their casino operations to be adjacent to their existing country club area. As a part of the casino design, it was determined that existing EMWD water and sewer lines would be destroyed by casino grading operations and increased capacity was required to allow increased flow.


ERSC was retained by the Tribe and Eastern Municipal Water District to facilitate the relocation of the 12” CML&C water line and the reconstruction of the 10” sewer line to a 15” gravity sewer line located on the site. The design was created in accordance to EMWD’s standards regarding size, materials, as the maintenance of the line is not to be assumed by the Tribe. The relocation of the waterline will connect to the existing tie-in points at the north and south sides of the site. The sewer line will connect to an existing lift station offsite and be pumped via force main to EMWD facilities.


ERSC was also responsible for the preparation of easement documents of the establishment of a 40’ utility easement. This utility easement will be used to not only relocate the 12” waterline, but also to construct a 15” sewer main that is also designed by ERSC.
