We just finished up the last round of winterizing hydrants. Do those of you who are in hydranted areas (dry hydrant), winterize your hydrants yearly? We have a lot of hydrants we have to manually pump because they hold water. It is a great way for new guys to learn the streets and the hydrant locations.

We have dry hydrants that hold water but they are burried under ground so we have never done anything to winterize them and never had a problem. I was just wondering if you have a shutoff in your hydrany or how that works? I am not trying to be a smarta$$ or anything I just know the way our hydrants are set up you can't pump them dry unless you pump the pond or river dry. I am just not getting a visual of how one goes about pumping the water out of a hydrant without more water comming in to refill it.

Here is how ours are set up so you can see my confusion.

I believe he was referring to dry barrel hydrants, not to be confused with dry hydrants, like you've ilustrated above.

In my town, the water department takes care of the hydrants, although I'm not sure if they winterize them or not. Probably not a bad idea seeing the winters here in Chicagoland are brutal!
What... why... winterize hydrants??? No i am just kidding! Thanks!

This will be our first winter with hydrants - the water system was completed late last winter. So we will be out shoveling them for the first time too.

I hadn't thought about winterization, but our assumption is that being newly installed the hydrants will drain properly. Good idea to inspect them, though before the snow flies.
Yes I am referring to dry barrel hydrants. We use an electric pump to drain the water out of the hydrant that is holding water. The hydrant is also painted accordingly. This is not a lake fed system this is a city pressurized water system. We do just over 1000 hydrants every year (fall). Sorry for the confusion.
Hey Joe,

I hope the snow plow drivers are nice to 'em. TCSS
Hay thanks now it all makes since. If you hadn’t guessed I am on a volunteer rural department and we don’t have dry barrel hydrants. I always thought the city hydrants had some type of bleed off that would allow the water above the shutoff to drain.
Dry barrel hydrants have a self-draining feature that allows the water to drain into the surrounding soil. When installed, hydrants should be set in a bed of gravel or crushed stone to facilitate draining.

If a hydrant is not thus installed, or is quite old, it may not be able to drain. Thus, it's prudent to inspect them and pump them out if required before the cold weather sets in.
thanks Joe
Yes are water department took care of them but we have maps on there locations and color systum for them like red is a 6 in main green is 4in and blue is 12in and black is the end of main so when we do train the new guys we ask ? on locations and main size this helps out a lot when there is a worker we know what size main is on that block and after the call we let water co know to rewinteriz
I do believe all of our hydrants have been taken care of in Washington Twp.
Yep we're all set for snow! :)
