Why does the City perform hydrant flushing? 

Hydrant flushing is the quick release of water from fire hydrants. It’s a controlled procedure that is vital to the general maintenance of the City’s water distribution system. It ensures adequate water flow is available to fire fighters, residents and businesses. It also helps maintain the City’s water clarity and quality by clearing iron and mineral deposits from the water mains (distribution pipes). 

What are the effects of hydrant flushing? 

Hydrant flushing helps ensure water quality and helps avoid random bouts of rusty water if there is a high demand for water, such as a major firefighting effort or high usage during a sustained drought. 

Why is my water rust/tea-colored from the hydrant flushing? Is the water safe? 

Sometimes, hydrant flushing can make the water temporarily appear rust-colored because the iron and mineral deposits in the water get stirred up. Water is safe to use and consume during hydrant flushing, however it may stain laundry. 

The main component of the discoloration of the water during hydrant flushing is caused by iron deposits from inside the water mains. 

Does the City test the water regularly? Is the testing done at various sites? 

The City of Country Club Hills is required by the U.S. Environmental Protection Agency and the Illinois Environmental Protection Agency to test the water in the system at various times throughout the year according to mandated parameters. The results of these tests are outlined in the annual Water Quality Report available on the City website. (The report is sometimes called the Consumer Confidence Report.) The 2023 report shows the City is in compliance with all the required testing parameters. 

Although the water is discolored during hydrant flushing and may look unclear or tinted, the water is not harmful or contaminated. To ensure the highest possible quality of water and in accordance with regulations, the City’s Department of Public Works/Water Division collects samples from 15 separate collection points every month, from areas all over the water system. This sampling takes place even during hydrant flushing operations. These samples are then analyzed for bacteriological contamination. Historically, the City of Country Club Hills has been in compliance with these samples, which means there are no bacteria in the water. 

How come my water is discolored, but my neighbor didn’t notice any discoloration? 

If you were home when the flushing was going on and you turned on your water, your water may be discolored because you are drawing in the water as the city’s system is flushing it and stirring up the iron and mineral deposits. 

If your neighbors were not home all day and returned home in the evening and turned on their tap when no flushing was occurring, they most likely will not notice any discoloration. 

My water is discolored. What should I do? 

Run the cold water tap until the water runs clear. If you have a water softener and are experiencing discolored water, place the unit into regeneration or cleaning mode for one cycle. Remember, rust colored water is safe, but it may stain laundry. If this happens, keep clothes wet and treat them with stain remover. The City offers free stain remover at no cost and is available for pick up at the following facilities: 

• Public Works, 18300 Marycrest Drive 

• City Hall, 4200 183rd Street
