Monroeville water contains approximately one part per million of Fluoride.

Residential and commercial meters are read every month.

Residential customers are responsible for the section of sewer line starting at the tap on the main line and extending upstream to the home. This is most commonly referred to as the sewer lateral. The lateral may extend across roadways to reach the MMA owned main sewer line. In this case it is still the responsibility of the resident.

Residential customers are responsible for section of waterline from the shut off valve located near the edge of the street (curb stop) up to the water meter. Also all plumbing after the meter is the customer's responsibility.

Checking for leaks at your meter.
First you need to turn off all water using appliances and fixtures. Then observe the small leak detection triangle that is located on the dial of your water meter. If this triangle is rotating (even very slightly), there is water leaking.

Checking for toilet leaks
Toilet leaks can be detected by adding a few drops of food coloring to the water in the toilet tank. Leave the food coloring in the tank for at least ten minutes. If colored water appears in the bowl, the toilet is leaking.

The hardness for 2013 has ranged from 79 - 101 mg/l

The property owner is liable to pay the tenant unpaid bill for service rendered to the tenant by the Authority. 

Pollution of the water supply does not constitute an actual health hazard, although the quality of the water is impaired with respect to taste, odor or utility. Contamination of the water supply, however, does constitute an actual health hazard; the consumer being subjected to potentially lethal water borne disease or illness.

In order to ensure that the water coming from your tap is suitable to drink, the EPA and the Pennsylvania Department of Environmental Protection (PADEP) have established regulations that limit the amount of certain chemicals in water provided for public water systems. Refer to the attached charts detailing our water quality test results for a complete listing of detected contaminants.

Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. The presence of these contaminants does not necessarily indicate that the water poses a health risk. To obtain more information about chemicals and potential health effects, call the EPA's Safe Drinking Water Hotline (1-800-426-4791) or visit their web site:

State and federal regulations require the disinfection of all public water supplies. The EPA and other health agencies recognize that using chlorine is one of the most effective ways to protect public health from disease causing organisms that can be found in surface waters. Because chlorine used alone can react with natural materials in the river water to chemically form disinfection by-products such as Total Trihalomethanes (TTHMs), the Authority has been evaluating chlorination procedures to reduce the formation of TTHMs. However, we will continue to ensure that the water distributed to your home has a sufficient "chlorine residual" to prohibit the growth of bacteria and other organisms, to not increase TTHMs, and to not have an offensive chlorine smell and/or taste.

The MMA receives its primary supply of finished water for resale from the Wilkinsburg – Penn Joint Water Authority (WPJWA) system. Like the majority of water utilities in the U.S., the WPJWA uses a multi-step treatment process at their water treatment plant. River water is pumped from the Allegheny River to the treatment plant and chlorinated. The water is then coagulated (which means the smaller particles in the river water join together by adding chemicals, which encourage this attraction). The water is mixed to ensure that the added chemicals are well blended and reacting with all of the smaller particles. The water is allowed to settle so that the newly joined particles sink by gravity to the bottom of the sedimentation tanks. The sediment is then removed and sent to the Allegheny County Sanitation Authority (ALCOSAN) for treatment. The settled water is then filtered to remove any remaining particles. Chlorine is then again added to prevent the growth of bacteria during transport and storage.

The finished water enters the MMA system through two separate metered connections. By agreement with WPJWA, the  MMA is permitted to withdraw 6.0 million gallons per day (mgd) of monthly average flow and 7.5 mgd of peak daily flow from the above connections. In addition to the primary source of supply, the MMA maintains two emergency interconnections with the Municipal Authority of Westmoreland County (MAWC) system. The MMA maintains four storage tanks to serve as a reserve for fire protection and to maintain adequate water pressure. These tanks have a combined capacity of 13.5 million gallons. The water is then delivered to your home or business through a network of over 165 miles of waterlines varying in size from 4 to 24 inches in diameter. If you desire more information about the quality of the water provided by the MMA, please call the MMA Manager, Joseph Storey or log on to our web site at http:// The MMA Board of Directors meets at 7:00 p.m. on the fourth Monday of the month at 219 Speelman Ln., Monroeville, PA 15146, and these meetings are open to the public. The MMA water system identification number is 5020027.

Microbiological contaminants (bacteria, viruses, protozoan, etc.) can come from sewage treatment plants, septic systems, agricultural live stock operations, and wildlife.

Inorganic chemical contaminants, such as salts and metals, which can be naturally occurring or result from urban stormwater run off, industrial and/or domestic wastewater discharges, oil and gas production, mining, or farming.

Pesticides and herbicides which may occur from a variety of sources such as agriculture, urban stormwater runoff, and residential uses.

Organic chemical contaminants, including synthetic and volatile organic chemicals, which are byproducts of industrial processes and petroleum production, and can also come from gasoline stations, urban stormwater runoff, and septic systems.

Radioactive contaminants, which can be naturally occurring or be the result of oil and gas production, or mining activities.
