Officials at Lake Mead National Recreation Area have received a proposal from the Clark County Water Reclamation District (CCWRD) to expand the existing sewer system in the lower Moapa Valley, which includes the townships of Overton and Logandale, Nevada. The existing collection system and treatment plant serves approximately 3,200 residences of the 6,000 that comprise Moapa Valley. The area is experiencing unprecedented growth and the CCWRD is proposing to expand the existing collection system to accommodate the immediate and future needs of the community. The proposed improvements include:
* 75,560 linear feet of gravity pipeline split on either side of the Muddy River
* Pipeline crossings on two existing bridges
* A 29-million-gallon-per-day (MGD) sewer lift station on a 3-acre site
* 29,100 linear feet of sewer force main
* Four parallel buried crossings of the Muddy River on Lewis Avenue
* 9,700 linear feet of access road between the lift station and the treatment facility
The proposed project would occur mainly on private land; however, the force main at the southern end of the project area would cross National Park Service (NPS) and Bureau of Land Management Land (BLM) land immediately north of the Overton Wildlife Management Area.
The CCWRD has an existing 40-foot right-of-way from the NPS in which an access road and sewage force main are located immediately north of the Overton Wildlife Management Area. The CCWRD is requesting a 100-foot right-of-way from the NPS which would be used to construct a water line, additional force mains, and a conduit bank necessary to operate and maintain the treatment facility.
An environmental assessment will be prepared to identify and evaluate potential alternatives, including no action, for the wastewater improvements. Officials at Lake Mead National Recreation Area are seeking public input on alternatives and on potential issues and impacts to be addressed in the environmental assessment. Written comments, which must be received by Nov. 2, 2006, should be sent to: Superintendent, Lake Mead National Recreation Area, Attention: Compliance Office, 601 Nevada Way, Boulder City, Nevada 89005.
