When you enable consumption threshold alerts, you will be notified if the water consumption at your property exceeds daily and/or monthly consumption thresholds you set based on your average daily and/or monthly consumption.

If you receive a consumption threshold alert, login to the Customer Portal and select Consumption from the menu on the left.  Use the Monthly, Daily, and Hourly views to review the usage at your property.  The information on this page will help you determine if there is abnormal consumption at your property and identify potential causes.

There are often explanations for exceeding the consumption thresholds you set that are not related to leaks (e.g., a house full of guests or a hot tub refill).  If this is the case, you can monitor your water consumption over the coming days to verify that it returns to normal.  If your water consumption has increased due to the start of irrigation season, please adjust your consumption thresholds accordingly.

If you cannot identify an explanation for the abnormal consumption, please take the following steps:

• If you are not currently at your Mammoth Property, contact your property manager or a local contact to help you identify the source of the abnormal consumption.
• Walk the inside and outside of the property and listen for running water at each fixture. 
  • Common sources of leaks in the home include toilets, faucets, showerheads, hose bibs and landscape irrigation. 
  • Less obvious sources of leaks include water heaters, ice makers, dishwashers, water softeners, and filtration systems.
• If you suspect that there is a running toilet, drop a dye tablet (available at the District at no cost) or a few drops of food coloring into the toilet tank.  Wait at least 30 minutes.  If the dye has run into the bowl, the toilet has a leak.
• Check the crawl space for running water.
• Turn off the shut-off valve at the home.  Leave the water off for a few hours to help identify if the potential leak is at the home or at the main water line.
• If the origin of the abnormal consumption cannot be identified, contact the property manager or a plumber for assistance.  If a water shut off at the meter is needed in order to complete a repair, please contact the District at support@mcwd.dst.ca.us or 760-934-2596 during regular business hours.  Please do not call the after-hours phone line unless you are experiencing an emergency.
