Fire Hydrant Flushing

About Hydrant Flushing & Testing

Maintaining Water Quality & Emergency Readiness in De Soto

Fire hydrant flushing is a proactive maintenance process used nationwide to clean water mains and ensure fire hydrants are in top working order. In De Soto, the City’s Water Division works alongside the Northwest Consolidated Fire District to regularly test and flush hydrants across the community.

It’s not just about safety—it’s also about quality. Over time, natural minerals like iron and manganese can build up in water mains. Flushing helps clear these out, improving clarity and taste while keeping the system healthy.

Why We Flush

Ensure hydrants are operational in case of emergencies
Maintain clean, clear water by removing sediment
Prevent buildup from causing discoloration after main breaks, construction, or firefighting activity

What to Expect

During flushing, you might notice:

Aesthetic issues such as temporary discoloration of drinking water (usually yellow or brown) caused by harmless mineral deposits
Slight pressure drops in nearby areas
Water pooling along curbs or storm drains

These effects are temporary and normal. If you notice ongoing discoloration or pressure issues, contact our team (info below).

To help check your water after flushing:

Run cold water from a tap (preferably from a bathtub or outdoor spigot) for 2–3 minutes
If water stays discolored, wait an hour and try again
Avoid using dishwashers or washing machines until your water runs clear

How You Can Help

Keep a 3-foot radius clear around fire hydrants—no fences, shrubs, or obstructions
Drive cautiously around active crews
Don’t report hydrants discharging during known flushing windows unless you notice unusual activity

Questions or Concerns?

Discolored water lasting more than a few hours?
