User Care and Maintenance Tips and Information

1. Check the water level in your cistern. If you are not getting water, it could be because your cistern pump or pressure tank has failed.  Feed a tape measure down your cistern’s stand pipe and check the water level (see diagram). If there is more than a foot of water, the problem is probably with your plumbing hardware. MMWC customers are responsible for servicing their own plumbing system.  In that case, call a plumber to check the system.

If your cistern is empty, your cistern or the service line feeding it could have a leak or the line could be frozen. Call the MMWC Offce to discuss the problem or leave a message with a complete description of the problem.

2. If your cistern is dry, shut off your cistern pump to prevent it from overheating or burning out.  It is best to turn off the circuit breaker that serves the pump; if it is not served by a circuit breaker, disconnect the power to the pump by some other means.

3. Understand MMWC’s practices on water delivery by truck. When water service is interrupted due to a freeze or break in a MMWC main, it has long been MMWC’s practice to truck a reasonable amount of water to MMWC’s affected customer without charge.  If a customer's service line (i.e. customer side of the meter) is frozen or inoperable and MMWC needs to deliver water, delivery fees apply.  Understand MMWC’s limits on the timing and frequency of such deliveries.  See MMWC’s Resolution Regarding Water Delivered by Truck.

You should inspect your cistern annually. Over time, dirt collects on the bottom of the cistern, and microbes grow on the cistern walls. Periodically, a proper cleaning is necessary.

You can view a guide from the Centers for Disease Control that provides useful information on disinfecting and sanitizing your cistern.

The property owner is responsible for any repairs from the connection with the water main. This includes cisterns and service lines, which can crack; valves, which can corrode (photo at left); and your pump and pressure tank, which can fail. The float valve (figure at right) is the most critical component. If it fails or gets stuck in an open position, your cistern will overflow. It should be replaced at least every 10 years. Your cistern’s float valve is above the water level in your cistern, and can freeze shut during the winter. Install a heater in the cistern ring during the winter to prevent such an incident.

Check your water usage and periodically look at your cistern and the area around it. Make sure there is no water and that the ground does not “look wet”. If you notice dampness or water, call the MMWC Office.

You should have a tight-fitting inner lid to your cistern box. If yours is broken, or if you don't have one, get one! Your concrete riser (manhole) should be properly sealed to the cistern box, to prevent heavy rains from seeping through the joint into your cistern. The top of your cistern’s concrete riser (manhole) should have at least 6-8” of ground clearance and surrounding ground should also be sloped away from the cistern riser to keep rainwater runoff out.

Although not under the responsibilities of MMWC, use and care of their septic system is of interest to our members. Here is a guide that provides useful information on septic system use, care, and maintenance that should be helpful.
