Human development has caused damage to the 'Water
Environment' for centuries by using inappropriate methods of drainage.
At present, rain from roads, car parks and other
hard surfaces is collected in gulleys and pipes.
It can cause:
|
|
| Flooding because
rain is piped to watercourses before it has a chance to soak into the ground,
all water arrives in streams and rivers at the same time |
| Pollution because
silt, oils and other pollutants are carried straight to streams and rivers
before they can be trapped, removed and broken down naturally. Watercourses
are severely damaged. |
| The Environment Agency recognises the damage
conventional drainage is doing to the environment and now advocates a new
approach to managing rainfall that replicates natural systems. It is called
Sustainable Drainage or SUDS. |
