Lake Forest Hydrant Flushing Starts: Run Cold Water From Your Basement, Garden Hoses

LAKE FOREST, IL - City of Lake Forest Water and Sewer crews started flushing local fire hydrants this week of accumulated sediment build-up.

This process is expected to improve water flow and quality throughout the water main system, according to a community alert.

"You may experience lower than normal water pressure and a short period of water discoloration during flushing and shortly thereafter," the notice to residents said. "Though the water may be discolored, it is safe to drink. However, until the water runs clear, it is advisable to avoid washing clothes, especially white fabrics."

Once the hydrants in residents' surrounding neighborhoods have been flushed, they're advised to run cold water from their basement utility sink or a hose outside.

"This will flush any rusty water out of your water service line," the alert said. "Never run warm or hot water immediately after a hydrant has been flushed, as this could lead to sediment getting into your hot water heater."

Should delays occur that require changes to the maintenance schedule included below, revised dates will be posted on the city’s website.

The current schedule is as follows:

• April 17 – April 21: East of Western Avenue from the north City limits to Westleigh Rd., including Villa Turicum.
• April 24 – April 28: Between Western Avenue (including Western Avenue) and Rt. 41 from the north City limits to Old Elm Rd.
• May 1 – May 5: West of Rt. 41 from the north City limits to Rt. 60
• May 8 – May 12: West of Rt. 41 from Rt. 60 to Everett Rd.
• May 15 – May 19: South of Everett Rd. to south City limits west of Rt. 41***

***In this area crew will conduct directional flushing in which sections of water main will be isolated to maximize results. Residents will be notified 24 hours in advance of any water outages in this area.
