The production of water impermeable surfaces in
Construction is inevitable. This includes roof areas on
buildings, car parks, loading bays and road pavements. The
provision of these surfaces interrupts the natural drainage
process creating increased stormwater runoff in respect of
both volume and flowrate. |
|
Benefits |
|
System can be designed to suit the application. |
|
Speedy construction using a standard joint. |
|
No need to fabricate on site - no need for
external specialist contractors. |
|
Straight forward installation using known techniques
- no need to retrain. |
|
Can be installed under roads. |
|
Long term solution. |
| |

|
| Design |
| The design of the system can be tailored to suit most
structural and hydraulic criteria. |
| |
|
| |
|
| Structural |
| The inherent structural strength of the concrete pipe is
well documented and can be designed to meet the severest
of loading criteria. Easi-Storm can also be tailored to suit
low load situations when the tank is to be situated below
verges or gardens. |
| |
|
| |
|
| Hydraulic |
| The graph below can be used to determine the appropriate
unit size by its nominal storage capacity. |
1. |
Take a horizontal line from the storage volume
required. |
2. |
Take a vertical line from the pipe length allowed. |
3. |
At the intersection read off the pipe required. |

In many cases this increase in stormwater flow and volume
is not a problem as the local sewer or watercourse has
sufficient capacity to cope. However in many situations
the local network is running full and the local watercourse
would be adversely effected by any increase in flow or
volume. |
|
|
| |
|
|
|
|
| |
These problems could be alleviated by an increase in
the size of the stormwater sewer or watercourse, thus
providing enough capacity within the drainage system to
cope with the increase in surface water. This however may
be expensive, cause major infrastructure disruption and
may be completely unfeasible. |
|
|
| |
|
|
|
|
| |
The type of systems which can be employed to overcome
these problems are well documented varied and in some
cases very technical in their operation, maintenance and
construction. The selection of a system will depend upon
site constraints, position, nature of the problem and
inevitably cost.
The Easi-Storm system offers a complete solution to the
stormwater attenuation problem and utilises a tried,
tested and accepted method of stormwater storage. FP
