Village of Alden Stormwater

• Pictorial view

2
Here is a view of rainfall and notice how the
water carrys away from the center of the road to
the sides
3
Here is another view where the "crown" or center
of the road has pitched the water towards the
curbs.
4
In this view you can see how the water has
collected in the gutter away from the road crown.
5
Here you can see water flowing to you in the
gutter
6
In this street there is no gutters or curbing so
water flows down the shoulders.
7
At certain points water falls into collection
points which we call DI's.
8
DI's are also found in low points of yards
9
On some streets water runs from the DI to a main
trunk line that runs along the street. This
manhole cover is directly over the main and is
opened for inspection and cleanout.
10
This is a view of DI's that has not been
installed as of yet. These units are precast
concrete and come in different sizes. The indents
on the sides allow for piping to be installed.
11
This is a view of the inside of a DI.
12
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.
13
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.
14
Some of the piping is made from galvanized steel.
15
The more modern piping is ADS pipe, which is
rigid and non corrosive.
16
This ADS pipe is more flexible and is used for
under drainage.
17
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.
18
You can see the flow of water from upper left to
the lower right in the early stages of this
retention pond.
19
This retention pond has collected water to keep
away from these apartment buildings.
20
This is another view of the same pond.
21
Here we see a main line emptying into a creek.
22
Here you see two outfalls dumping into the creek.
They are flowing over rip rap stone to prevent
erosion of the creek bank.
23
This outfall is coming through the side of a
bridge abutment.
24
This is a creek flowing under a sidewalk and road
bridge.
25
This shows a ditch joining a creek.
26
Under drainage flowing into drainage ditch.
27
Two ditches joining together before entering a
roadway culvert.
28
Drainage ditch from Willow Woods, Meadow, and
Homecourt subdivisions heading towards Ellicott
Creek.
29
Ellicott Creek just below flood stage.
30
Ellicott Creek behind WW treatment plant.
31
Brush and yard waste should not be placed in
gutters, along curbs, or in the streets.
32
The brush and yard wastes should be placed on
the yard side of the gutters, curbs and streets.
33
Notice the ponding behind this pile of yard waste.
34
The yard waste placed in this gutter has backed
up the water to flow into this yard and also is
causing partial blockage of the DI grate.
35
The arrows point out the water blocked up behind
this yard waste pile.
36
Water blocked behind this yard waste pile.
37
This is a wad of roots pulled out of a outfall
into a retention pond. The roots came from a tree
that a homeowner planted near the drainage system.
38
This gives you perspective on how large the root
blockage was.
39
This was a blockage in Ellicott creek caused by a
tree falling over.
40
The tree blockage caught any debris flowing down
the creek and created a huge dam. There is
approximately an 18" difference of the height of
the water on both sides of this dam.
41
This is the same area after DPW workers cleared
out the dam that was on village property.
42
This is some of the debris that was cut up and
hauled out of the creek from the dam.
43
More debris removed from the dam.
44
Drainage ditch that was cleared out of overgrowth
along side of Willowwoods park.
