Alamogordo Hydrant Testing: What Flow and Glow Means for You
Published 18 October 2026
The City of Alamogordo is launching Hydrant Flow & Glow, a citywide project to inspect, flow test, repair and repaint fire hydrants all over town. If you see crews at the hydrant on your street, water running down the gutter or a hydrant turning silver, this is why. The short version for homeowners: it is normal, it helps keep hydrants ready for a fire, and it can briefly make your tap water look cloudy.
What is Hydrant Flow & Glow?
It is a community-wide project to check how every hydrant is working and give each one a fresh coat of paint. According to the City of Alamogordo Hydrant Flow and Glow page, crews will inspect hydrants for leaks and damage, flow test them, flush and maintain them, record what they find and repaint them.
The “Flow” part is the flushing and testing. The “Glow” part is the paint job, which includes reflective glass bead so hydrants are easier to spot at night.
| What crews do | Why it matters |
|---|---|
| Inspect for leaks, damage and access problems | Finds problems before an emergency |
| Flow test pressure (PSI) and flow (GPM) | Shows how much water each hydrant can deliver |
| Flush and check caps, threads and drainage | Keeps hydrants working and clears sediment |
| Record results in the city's GIS mapping system | Helps the city plan repairs |
| Strip, prime and repaint in silver with reflective bead | Protects hydrants and improves night visibility |
Who will be working on the hydrants?
The city hired M.E. Simpson Co., Inc. for hydrant testing and maintenance and Giant Maintenance & Restoration, Inc. for preparation and painting. City Utility Department crews will also help, with Water Production handling repairs and Utility Maintenance replacing hydrants that cannot be fixed.
The city says field crews will work in teams of at least two, wear visible ID badges and drive vehicles with company and City of Alamogordo contractor signs. That is a good detail to remember if someone is working near your yard.
How does a flow test work?
The city explained it in three steps on its Facebook page this week. First, crews measure the pressure in the system before any water flows, called static pressure. Then they open a hydrant and measure the pressure that remains, called residual pressure, and finally they measure how many gallons per minute come out.
Together those numbers show how much water the system can deliver while holding pressure, which matters for fire protection.
Could hydrant testing affect my water?
It can, for a little while. The city says opening hydrants can stir up sediment in the pipes, which may make your water look discolored or cloudy and taste a little off.
The city's hydrant flushing tips say the water stays safe and meets federal and state standards. Here is what the city recommends:
- If you can, avoid using water while crews are flushing nearby.
- If your water looks discolored afterward, run the cold taps for 5 to 10 minutes or until it runs clear.
- Hold off on laundry until the water is clear, then wash a dark load first, since discolored water can stain fabric.
- If pressure seems low afterward, clean the screens on your faucets.
What does this mean for homeowners and buyers?
Working hydrants are part of what keeps a neighborhood safe, and good hydrant records help the fire department plan. For buyers, it is one more sign the city is investing in its water system, which I wrote about in my post on Alamogordo's 40 year water plan.

Frequently Asked Questions
What is Hydrant Flow & Glow in Alamogordo?
It is a citywide City of Alamogordo project to inspect, flow test, maintain and repaint fire hydrants. The goal is to find problems early and keep hydrants ready for emergencies.
Why are Alamogordo fire hydrants being painted silver?
Crews remove old paint and rust, then apply a primer and a silver finish coat. Reflective glass bead is added to make hydrants easier to see at night.
Is my water safe during hydrant testing?
The city says hydrant work can stir up sediment and make water look cloudy or discolored for a while. It says the water is still safe and meets federal and state drinking water standards.
What should I do if my water is discolored after hydrant flushing?
Run your cold water taps for 5 to 10 minutes or until the water runs clear. Wait to do laundry until the water clears, then wash a dark load first.
Who is doing the hydrant work in Alamogordo?
M.E. Simpson Co., Inc. is handling testing and maintenance, and Giant Maintenance & Restoration, Inc. is handling preparation and painting. City Utility Department crews are also doing repairs and replacing hydrants that cannot be fixed.
