Sewer Service Study

Formed as a County Water District in 1927 by a vote of the people, Monte Vista Water District is authorized to provide water, sewer, and other public services. MVWD currently provides retail and wholesale potable and non-potable water services. 

In early 2020, property owners and San Bernardino County requested that MVWD explore providing sewer service in unincorporated portions of its service area. MVWD is embarking on this exploratory process that includes:

  • Feasibility Study
  • Local Agency Formation Commission (LAFCO) Approval
  • Inland Empire Utilities Agency (IEUA) Approval

What are the benefits of sewer service?

  • Improved Wastewater Management - MVWD can provide access to sewer service in an area that currently relies on underground septic systems for disposal of domestic wastewater.  
  • Better for the Environment - Septic systems add contaminants into the local groundwater. Collection and treatment of wastewater through sewer service would improve groundwater quality in the Chino Basin. 
  • Increased Local Recycled Water Supply - Septic systems add contaminants into the local groundwater. Collection and treatment of wastewater through sewer service would improve groundwater quality in the Chino Basin.
