Annual Hydrant Flushing & Testing
Each spring and summer, you may notice crews from the North Ridgeville Fire Department and Public Works Department working on fire hydrants throughout the city. This process often involves releasing large amounts of water into the streets. While it may seem like water is being wasted, hydrant flushing and testing are essential maintenance activities that provide several benefits, including:
- Ensuring Proper Operation – Verifies that hydrants are functioning correctly.
- Assessing Water Flow – Evaluates the available water pressure for firefighting.
- Enhancing Water Quality – Removes mineral and sediment buildup from water mains.
- Meeting EPA Requirements – The Ohio EPA mandates flushing 25% of hydrants annually for water quality assurance.
Why Hydrant Flushing Matters
The Public Works Department aims to flush 25% of the city’s hydrants each year as part of routine maintenance. This practice is vital for public drinking water systems because it helps identify malfunctioning hydrants and valves, ensuring they work at maximum efficiency.
Additionally, the Fire Department conducts pressure tests on 20% of the city’s fire hydrants annually, meaning every hydrant is tested at least once every five years. These tests confirm that hydrants are in working order and can provide the necessary water pressure for firefighting operations.
Over time, water can stagnate and develop biofilm (a thin layer of microorganisms) inside distribution pipes. This can impact water taste, odor and quality. Flushing helps refresh the system, ensuring clean, safe drinking water. Some residents may notice a temporary chlorine smell, which is normal and will dissipate throughout the day.
Understanding Water Discoloration
Hydrant flushing can stir up natural sediment in the pipes, leading to temporary water discoloration. While this may affect the water’s appearance, it remains safe to drink. Running cold water for a few minutes usually clears up any discoloration. If needed, repeat the process. Avoid using hot water, as it can draw sediment into your water heater.
For laundry concerns, refrain from washing clothes until the water clears. If staining occurs, do not dry the clothes—rewash them with detergent and a rust-removing agent. Free rust remover cleaning packs are available from the Fire Department by contacting Michelle Smith at (440) 490-2040 (Monday-Friday).
Frequently Asked Questions
How does hydrant flushing work?
Hydrant flushing increases water flow, stirring up and removing minerals and deposits from the pipes.
When does hydrant flushing occur?
Hydrant flushing and pressure testing take place throughout the spring and summer months.
Will flushing affect my water service?
Your water service will not be interrupted, but you may notice a temporary drop in pressure. If pressure remains low after flushing, check your faucet for trapped particles.
Why is my water discolored, but my neighbor’s isn’t?
If you used water while hydrant flushing was underway, discolored water may have entered your plumbing. A neighbor who did not use water at that time may not experience the same issue.
Why is my water discolored if flushing is happening in another part of the city?
Sometimes, hydrant flushing can cause water to flow in the opposite direction, affecting areas beyond the immediate flushing zone. The Public Works Department takes steps to minimize these impacts.
Does the Public Works Department coordinate with the Fire Department?
Yes, both departments work together to avoid flushing hydrants that have recently been tested.
