City Of Highwood Hydrant Flushing
The City is currently fire hydrant flushing. This flushing will take place over the next few weeks and will be usually noted by signs indicating flushing in the area. A hydrant flushing program is very important to water quality. Over time, various materials such as corrosion products and organic materials, build up in the mains of municipal water distribution systems. This buildup can cause water quality issues such as unusual tastes and odors and discoloration of the water. Hydrant flushing programs are instituted by municipalities to flush the buildup out of the mains. In a traditional hydrant flushing program, hydrants are opened one at a time in a general area, which increases the velocity of water in the mains. The increased velocity picks up sediment that has settled in the bottom of the main and lightly scours the walls of the pipe to remove residue, which is then carried out the open hydrant(s).
The hydrants are left open until the water runs clear.
You may experience lower than normal water pressure and a short period of water discoloration during flushing and shortly thereafter. 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. If any rust stains appear on your wet laundry, do not dry your clothes. Simply run the cold water in your house or at a hose until it is clear and then wash clothing again. This will flush any rusty water out of your water service line. Never run warm or hot water immediately after a hydrant has been flushed, as this could lead to sediment getting into your water heater. Normally rusty water events dissipate in 8-10 hours but could last longer depending on water usage in the area. If your water pressure or volume seems low after the flushing, please check/clean your faucet and washer screens for debris. Our plan is to exercise the hydrants between the hours of 8:00 am to 3:00 pm. These times may vary. If you have any concerns, please contact city hall.
