Water Meter/Meter Pit | Backflow & Cross Connections| Water Pressure

Water Meter/Meter Pit
You will be billed monthly for water use, as measured through your water meter. You can make sure your meter is read accurately each month, and help our meter reader by:

• Confining your dog while the meter is being read, or advising us that there is a dog. (Remember that a playful animal that romps harmlessly with your children is going to react quite differently when a stranger walks into its yard.)

• Keeping shrubbery growth and other obstructions away from meters.

• Keeping gates in good repair so that the meter reader has easy access in and out of your yard if necessary.

The District must have easy access to your meter pit at all times. It is your responsibility to plan and maintain landscaping so that it will not interfere with either maintenance or meter reading. The District has the right to remove and/or trim all restrictions within a 3-foot radius of the meter pit.Access to the meter pit and metering equipment is normally limited to District personnel. The District may, in certain limited circumstances, give permission to the customer for temporary access. Access to the pit by the customer to shut off the water will be allowed as needed. No connections shall be made to the meter yoke within the meter pit.

If the street or ground is not to final grade at the time of installation of the meter or if the grade is changed at any time, the owner is responsible for the cost of raising or lowering the meter pit when final grade is established.

Backflow & Cross Connections
When water flows backward through the water supply system, it is called backsiphonage or backflow. As you can see this can be very hazardous to your health!

The danger comes when the hose — any hose — is connected to a harmful substance. If the pressure in a water main drops while your hose is submerged in polluted or contaminated water, then the water (and whatever is in it) could be sucked back into your pipes and the drinking water supply. Water pressure drops are not uncommon. They can happen when firefighters battle a nearby blaze or before a District crew repairs a broken water main.

Some harmful substances you should be wary of are chemicals used to kill weeds or fertilize your lawn. The cleanser used on your kitchen sink could be hazardous if swallowed, as could the bacteria in the water from your wading pool or waterbed. Fortunately, keeping your water safe from these contaminants is easy. The following policies will help protect your drinking water:

• Never submerge hoses in buckets, pools, tubs, or sinks. Keep the end of the hose clear of possible contaminants.

• Don't use spray attachments without a backflow prevention device. The chemicals used on your lawn are toxic and can be fatal if ingested.

• Buy and install inexpensive backflow prevention devices for all threaded faucets around your home. They are available at hardware stores and home-improvement centers.

• State law requires a backflow device on all sprinkler systems. District policy recommends that all residential users install an approved backflow prevention device within their private water system.

Water Pressure
Water pressure in most District mains ranges from around 40 psi to 100 psi. Pressures outside this range do occur, however. Variations are based on a number of factors, including line size and elevation. Line pressure will also fluctuate throughout the day as water usage varies. Summer pressures are generally lower than winter pressures, due to the added demand of lawn irrigation. In addition, average main line pressures in an area may, over time, increase or decrease through the normal course of development of the water distribution system.

The District recommends that all customers install an adequate pressure-regulating device in their home to protect their household plumbing from high pressure. The District also recommends that irrigation sprinkler systems be designed to operate off the regulated household system, so they will not be affected by existing or future variations in main line pressure. The customer’s private service line, from the meter pit to the house, should be capable of withstanding mainline pressures of up to 200 psi.

Meter pits installed prior to June, 1992 may have a pressure regulator in the pit. The District will remove the regulator if requested in writing by the tap owner.
