Q. What is the difference between Monroe County Water Authority, Rochester Water Works and Pure Waters?

Monroe County Water Authority (MCWA) is an Authority created by New York State statute to supply clean water to residential, commercial and industrial customers outside of the City of Rochester.

City of Rochester Bureau of Water is a bureau of the City’s Department of Environmental Services, which supplies clean water within the City limits.

Pure Waters is a Division of Monroe County’s Department of Environmental Services. They treat the waste water collected in sanitary and storm sewers.

Q. Who is responsible for the water lines to my house?

MCWA maintains the water meter and the water service line from the water main to the outside shut-off valve. Homeowners are responsible for the service from the curb box to the house, including inside shut-off valves.

Q. Is it okay to plant near the curb box?

No. Plants, trees, shrubs or permanent fixtures can impede our ability to service your lines. It is recommended that you call Dig|Safely. New York at (800) 962-7962 before doing work at or near the right-of-way so that the utility companies can mark the location of their service lines.

Q. How long will my water be off during repairs?

It depends on the work being performed. About 50% of all breaks are fixed within four hours, and 90% are fixed within eight hours. Call (585) 442-7200 for information on your repair.

Q. Why are colored stakes, flags or paint marks on my lawn or sidewalk? They show the location of utilities in that area. We are required by law to mark our water lines any time a contractor will be excavating within 15′ of our mains. When these markers appear, it means excavation work has been scheduled or has recently been completed. Different colors are used to indicate the location of different utilities:

BLUE = water
RED = electric
YELLOW = gas
ORANGE = TV and cable
GREEN = Sewer

Q. Who do I call if I’m installing a swimming pool, fence or a sprinkler system in my yard?

Call Dig|Safely. New York at (800) 962-7962 to notify all utilities (including MCWA) to stake lines before you dig. If you are installing a lawn sprinkler system, contact our Backflow Department (585) 442-2000 to insure you are in compliance with NYS and County Health regulations.

Q. Where is my shut-off valve located?

It is about three feet off the floor near the meter, located on the wall facing the street where the water service pipe enters the building.

Q. What is water hardness?

Water hardness is a measure of the mineral content of water. MCWA water is considered moderately hard and contains between 5.6 and 7.6 grains per gallon of Total Hardness (100 to 125 milligrams per liter).

Q. Do I need a water softener?

No. A water softener isn’t necessary for water with moderate hardness.

Q. Why is my water fluoridated?

Water provided by the MCWA contains a controlled, low level of fluoride (about 0.7 parts per million) as recommended by the EPA to help prevent cavities.

Q. Is there lead in my water?

Lead is not in the public water supply when it leaves our treatment plants. However, lead might enter your water if it sits for long periods of time in private plumbing lines that have either lead solder or fixtures containing lead. Running the water for 15 to 30 seconds will clear out any lead that may be present in the water.

Although there is no detectable lead in the water that we deliver to your house, if you would like to have your drinking water tested to determine if your plumbing is contributing lead to your water, two state-certified laboratories that offer lead testing are listed below:
