Presentation on theme: "Village of Alden Stormwater Pictorial view. Here is a view of rainfall and notice how the water carry’s away from the center of the road to the sides."— Presentation transcript:
This is a look of a DI that has the grate open. Note the water pouring in the top. The two smaller pipes on the sides is bringing in water from under drainage under the streets. The bigger pipe is taking water away to the main.
This DI is made from block and bricks. The pipes are set so that any debris that comes in will settle to the bottom of the DI allowing the water to flow out.
Some of the piping is made from galvanized steel.
The more modern piping is ADS pipe, which is rigid and non corrosive.
This ADS pipe is more flexible and is used for under drainage.
The main line has dumped into this area we call a retention pond. The purpose is to collect runoff and release slowly to control flooding.
You can see the flow of water from upper left to the lower right in the early stages of this retention pond.
This retention pond has collected water to keep away from these apartment buildings.
