Showers | Multiply the number of daily showers by the number of minutes each shower takes. Now multiply that number by 3 gallons per minute used. Enter that number in the box. | |

Baths | Multiply the number of daily baths by 36 (gallons in a full bath) or 18 (gallons in half full tub). Enter that number in the box. | |

Toilets | Multiply the number of persons in the home by the number of daily flushers. (The average is four per person.) Multiply that figure by 3, the number of gallons used per flush. Enter that number in the box. | |

Brushing Teeth | Multiply the number of persons in the home by the number of daily tooth brushings. Multiply that figure by 3 (the number of gallons used while the faucet runs for one minute). Enter that number in the box. | |

Hand Washing | Multiply the number of times per day dishes are washed by the number of minutes the water is running. Multiply that by 3. Enter that number in the box. | |

Dishwasher | Add the number of times a week you run the dishwasher and divide by 7 to obtain the average daily usage. Multiply that figure by 12 (the number of gallons used by each wash). Enter that number in the box. | |

Laundry | Add the number of loads of laundry done weekly and divide by 7. Multiply that figure by 44 (the number of gallons used per load). Enter that number in the box. | |

Other Indoor Use | The people in your household use water in other ways. Multiply the number of persons in the household by 10 gallons. Enter that number in the box. | |

Outside Watering | You also use water outside (watering plants, washing cars, filling pools, etc.). Multiply the number of minutes you have a hose turned on by 6 and enter that number in the box. | |

Next, calculate your monthly use by multiplying the amount used daily by 30. Enter in the box. This is your estimated monthly usage. |

**CROSS CONNECTIONS**

Cross connections can cause the water system to be come contaminated. A cross connection is a link with the public water supply and a possible source of contamination. An example of a cross connection would be a garden hose submerged in a source of contamination such as a swimming pool, car radiator or other liquid. If a water main break should occur or if a fire pumper used a fire hydrant while the hose was submerged in a source of contamination, the contaminant could be pulled back into the public water supply. This occurrence, known as backflow, can be prevented.

One simple way to stop backflow is by using an air gap. An air gap can be created by arranging your house

hose to that the end is at least six inches above the top rim of the container it is being used to fill. This air gap

will prevent the contaminant from being siphoned into the water supply.

Another method of preventing backflow with a garden hose is using a device known as a vacuum breaker.

Vacuum breakers are inexpensive devices that can be screwed onto your outside faucet. These devices

will prevent contaminants from being siphoned back into your plumbing and the public water system.

More hazardous cross connections or cross connections created with permanently installed plumbing may require more sophisticated

devices known as reduced pressure backflow preventers. These devices are much more complicated and must be tested annually by

certified testers.

For more information on preventing cross connections and protecting our water supply, contact the Fall River Road Utility District at

** REMEMBER: Never submerge your garden hose in anything you would not want to drink!**
