The Northwest Municipal Joint Action Water Agency ( NSMJAWA ) has informed the Village of a possible leak on their 90 - in transmission main that delivers Lake Michigan water to the Village of Mount Prospect and surrounding member communities including the Village of Elk Grove Village , Village of Hanover Park , Village of Hoffman Estates , City of Rolling Meadows , Village of Schaumburg , and the Village of Streamwood .
Later this Spring , NSMJAWA will perform an exploratory excavation to determine the exact location of the leak and to ascertain what materials will be needed for the repair . The excavation will likely take several days to complete , and all NSMJAWA members will have to rely on a backup water supply while the exploratory excavation is being performed .
The Village will provide additional details once the date of the exploratory excavation has been decided .
If deemed appropriate , the agency may begin repairs immediately following the discovery of the leak , resulting in a shut - down of supply water to the Village . It is estimated that the repairs will take three ( 3 ) to seven ( 7 ) days to complete . During that time , the Village will utilize various interconnects with other suppliers and/or utilize the existing potable water deep well systems . All the other NSMJAWA members will also have to use alternate water sources .
The Village will initially utilize existing interconnections with the Village of Arlington Heights , the City of Des Plaines , and the Illinois American Water Company . These water purveyors all source Lake Michigan water from a different supplier and , therefore , are not affected by the shut - down . There should be no discernable difference between the water you normally consume and the water received from Arlington Heights , Des Plaines , or Illinois American .
However , some customers may initially notice a drop in water pressure . To receive water from Arlington Heights , Des Plaines , and Illinois American , the Village - owned water system must operate at a relatively lower pressure . If the pressure drops too low , or the emergency interconnections with Arlington Heights , Des Plaines , and Illinois American cannot convey enough water to meet demand , the Village will produce water from artesian deep wells .
These wells are each over 1 , 000 feet deep . The water is safe to drink though some may notice that it tastes , smells , and may even appear different than the Lake Michigan water that normally flows from Mount Prospect faucets . Public Works will disinfect the water with chlorine prior to distribution .
Please note , the Village began using Lake Michigan water purchased through NSMJAWA in 1988 . Prior to that time , the Village utilized these deep wells as its only source of drinking water for decades .
Should the Village need to use an alternate water source , we ask customers to limit water usage until the Village returns to its primary water source . Limiting water use includes:
Waiting to run the dishwasher or washing machine
Minimizing shower and bath use
Flushing less frequently
Avoiding all outdoor water uses
