MHCSD uses the latest technology to treat and deliver fresh, clean water for its residents. The MHCSD has taken extra measures to ensure water conservation. For example, irrigation computers will detect rainfall and will water landscaping accordingly in order to conserve water. Mountain House’s water comes from the Clifton Court Forebay along the Delta and is delivered by the Byron-Bethany Irrigation District (BBID). Water is treated by using various processes, filtered and pumped into the community for distribution. At present the state of the art Water Treatment Plant has a capacity of 12.5 MGD. The full build out capacity will be 20 MGD. The facility includes flocculation basin, sedimentation basin, filtration, clear well, UV disinfection, booster pumps and concrete sludge drying beds. There are a variety of regulations that pertain to water conservation. A few are listed below:

  • Irrigation in non-public areas is prohibited between the hours of 11:00 a.m. and 6:00 p.m. during the period between May 1st and October 1st
  • Escape of water through leaks, breaks, or malfunctions within a customer’s plumbing or distribution systems must be corrected within 24 hours after a customer discovers the leak.
  • Shut-off nozzles must be used on hoses when washing vehicles, boats or cleaning buildings or mobile home exteriors.

There are a variety of regulations that pertain to the method of water distribution which protect public health and maximize the life of the infrastructure that treats and distributes the water.

  • Property owners are responsible for maintenance and repair of the water line on private property from the point of connection to the public line.
  • No permanent structure may be built on top of utility lines within easements.
  • All water service connections shall have water meters.

Chloramine Notice


MHCSD provides wastewater collection, treatment and disposal systems to serve the entire community. Approximately 80% of the service area will drain by gravity to the treatment plant through a backbone collection system. The remaining 20% will be pumped to the treatment plant through lift stations and force mains.

The tertiary treatment facilities will include aerated lagoons, activated sludge, filtration, disinfection, effluent storage, and if necessary, interim farmland or permanent golf course irrigation.

The design capacity of the treatment facility and all related components will be 5.4 MGD (average annual flow) at build out. The treatment processes and facilities will be built in stages to appropriately serve one or more neighborhoods, as well as industrial/commercial and public uses.

Storm Water

MHCSD employs a variety of storm water drainage concepts intended to improve water quality. These measures enhance aesthetic, hydrologic, and biological functions of the water resources to minimize construction and maintenance costs, as well as protect the environment. Storm water main pipelines are designed to withhold a 100-year storm event, which is an event that has a 1% chance of happening in any given year. Within each Mountain House neighborhood, runoff will be collected in underground storm water pipes. These local conduits will connect to larger trunk lines in each neighborhood. For neighborhoods near Mountain House Creek or golf courses, local storm water pipes will connect directly to BMP (Best Management Practices) storm water basins located in the creek corridor or golf courses.

Water Pollution

The primary purpose of storm drains is to carry rainwater away from development to prevent flooding. Storm drains are not connected to sanitary sewer systems and water treatment plants. Many people don't realize that untreated storm water and the pollutants it carries flow into the streams, creeks, rivers and oceans where wildlife live and children play. Storm water pollution occurs when water rinses off streets, housing, parking lots and businesses into our gutters and storm drains, taking with it yard waste, litter, trash, grease, household cleaners and solvents, animal and human waste, lawn and garden fertilizers and soil erosion. Every year, streams, creeks, rivers and lakes are degraded by pollution.

Four Ways to Prevent Water Pollution

  • Dispose of yard waste more frequently. By disposing of leaf, grass, shrubs and other organic matter in your yard more frequently, less will wash into storm drains. Yard waste can be placed in the Brown Cart and is collected weekly during leaf pick up season.
  • Reduce reliance on landscape chemical products. Decrease the use of lawn and garden care products such as pesticides, insecticides, weed killers, fertilizers, herbicides and other chemical-based soil amendments and avoid over-irrigation when you do use them. Over-irrigation carries the garden chemicals into the gutter, down the storm drain and into our local lakes, rivers and bays. When possible, use non-toxic gardening methods.
  • Use a broom. Conserve water and prevent debris from flowing into gutters and down our storm drains by using a broom instead of a hose to clean sidewalks and parking areas. Sweep up debris and dump it into your trash can, and rake up yard waste and put into your Brown Cart.
  • Buy Non-toxic products. When possible, use non-toxic products for cleaning. If you must use a product that is toxic, buy it in small quantities, use it sparingly and be sure to properly dispose of unused portions.
