Belmont Terrace Mutual Water Company Has Levels of Manganese
Above the Secondary Maximum Contaminant Level

Our water system recently violated the Secondary Maximum Contaminant Level (MCL). A secondary standard affects the color and taste of the water delivered to customers. Although this is not an emergency, as our customers, you have a right to know what you should do, what happened, and what we are doing to correct this situation.

We routinely monitor for the presence of drinking water contaminants. Water sample results received on 12/10/2025 showed manganese levels of 0.072 milligrams per liter (mg/L). This is above the secondary MCL of 0.05 milligrams per liter (mg/L).

You do not need to use an alternative water supply (e.g., bottled water).

What happened? What is being done?

Well testing is being done quarterly and reported to the State Water Board. Belmont Terrace Mutual Water Company (BTMWC) is working closely with the State Water Board’s Division of Drinking Water and other consultants to determine measures that will bring us into compliance with state requirements.  In 2024 we increased chlorination levels to reduce manganese entering the distribution system which was effective.  We now must implement a system to remove manganese from the well before it enters the system. We anticipate resolving the problem within the next 12-15 months.  Updates will be shared with customers as progress continues.
For questions, contact us at Board@BelmontTerrace.org.

Please share this information with all the other people who drink this water, especially those who may not have received this notice directly (for example, people renting rooms or ADU’s.)

Pulling well pump out of the well

Old pump is out of the well

Yesterday, April 21st we installed a sensor in the storage tank to notify us if the water gets too low. Here is the sensor prior to putting it in the tank.

Conserve Water 4/22 – 4/23, 2025

To do this we will need everyone to practice conservation for at least two days.

We ask that you do NO OUTSIDE watering or laundry starting at Tuesday, April 22, 2025 at 3:00 am . (This will allow the tank to reach it’s maximum capacity before pulling the pump out of the well.)

If you have started your landscaping timers, please make sure that they are off.

It is OK to store water in barrels to use in the garden as long as you do it before 3:00 am on Tuesday, April 22, 2025 .

This conservation notice is required until we give the “All Clear” by taking down conservation signs. An email will also be sent out when normal consumption can resume.

We are working with the State and our contractor, Weeks Plumbing, to incur the least amount of down time for the well and inconvenience for our members.

We MAY have to issue a boil water notice. You will be notified if needed.

Friday morning, April 12th at 10am to about Friday, April 26th

As many of you may know, the water tank roof over our community water supply is about 70 years old. The board has been working hard on plans to replace it and we are finally nearing the point of the new installation. This new roof will ensure a safe and sanitary water supply for all of us here in the Belmont Terrace, and will last for many many years to come.

We have had to coordinate with four contractors for the final installation and it has become a very involved process which requires we all pitch in to make it go smoothly.

During the construction, we will be on a backup tank that only holds 5,000 gallons, compared to our main tank that holds 38,000 gallons. Obviously, this impacts the availability of water for all of us. The demo of the old roof and the installation of the new roof should take between a week and two weeks. During that time we ask that everyone in the Terrace restrict their water usage to inside the house only. NO outside watering should occur during the demo and installation and ALL outside automatic systems should be turned off as well. No one wants to turn on the tap have have nothing come out, and this conservation will help prevent that.

The installation is set up to start on Friday, the 12th of April.

Please be prepared. Some ideas for water saving that can be used both indoors and for outside watering (only if needed):

Fill garbage cans or other containers with water now and hand water new plants with that.
Fill bathtub when the final date is set and use for toilet flushing. We did this during the worst of the drought and it works great.
Use 5 gal bucket to collect water while shower is heating up and use to flush toilets or outside for watering of new plants.

If anyone has any other ideas on how to collect water now before conservation measures are needed, please let us know and we will share them with your neighbors!

We are all owners of the Belmont Terrace Water System and its maintenance allows us to remain in control of our water. Remember, this is for the benefit of our entire community and your help is greatly appreciated.
