About the Water System Master Plan and the availability of connections to MWSD’s water system.

Background — In 2003 MWSD acquired the privately-owned water system serving the Montara-Moss Beach area in the County of San Mateo.

In the 1980s, the company that owned the system was ordered by the California Public Utilities Commission to establish a moratorium upon new water connections to the system due to its substandard condition and lack of water resources. Upon purchasing the system with funds from a bond issue approved by over 80% of the voters within MWSD’s territory, the system came under MWSD’s local regulatory and operational control, but the moratorium was necessarily continued by MWSD due to the condition of the system.

MWSD has made substantial infrastructure improvements, implemented operational efficiencies and initiated conservation measures, all of which have contributed to the increased availability of water as documented in the Water System Master Plan recently updated and approved by MWSD’s governing Board. Accordingly, the Board has repealed the moratorium. Consequently, the availability of water is now directly related to data and projections included in the Master Plan.

MWSD’S Role — MWSD is a special district that provides water and sewerage service. It does not issue building permits or control development. Except for water service that may be provided to property that has already been developed and is served by on-site wells, new connections may only be made for property approved for development by the County of San Mateo, subject to the County’s building, planning and zoning regulations and the County’s Local Coastal Program

More About How We Continue Improving Water Quality

Since the community acquired the water system in 2003, we have made significant improvements, which have resulted in water quality improvements in turbidity, iron, nitrates, and color. To ensure future water quality and system reliability, the District is actively implementing a comprehensive program of system improvements, including the design and construction of additional storage facilities and a centralized water treatment facility. The District is committed to the responsible management of local water resources and has designed these projects to maximize system reliability while minimizing costs and environmental impacts.

    Clean Water Act 

    The link below provides interesting information about the Federal Clean Water Act. The Clean Water Act prevents direct discharges of pollutants into the waters of the United States through a program known as the National Pollutant Discharge Elimination System ("NPDES"). The NPDES program has very strict requirements, but it only applies to certain types of water pollution. The program regulates only "point sources" of pollution, which means that pollutants must be carried to the water body by an individual and direct conveyance, such as a pipe or storm drain -- such as from a wastewater treatment plant.
