Sometimes there doesn't seem to be enough rain. Other times there is too much. Maybe there isn't a lot we can do to control the rain, but there is a lot we can do to reduce problems caused by different rainfall patterns.

A new development at the London Wetland Centre in Barnes solves the problems of managing water with a “Rain Garden". We are likely to be hearing about it a lot more often over the next few years. The idea is that the garden owner can store rainwater and use it in dry periods. They can reduce the problems caused by extra rain this way.

One of the key problems that the rain garden tries to deal with is the problem caused by too much water in the street. In a natural environment, a lot of rainwater is sent back into the air by plants. Much is also absorbed deep into the ground, and flows into streams and rivers. What happens in city environments can be completely different —— a large, amount of rainwater flows straight off the hard surfaces of roofs and roads. The harder the rain, the less likely it will be absorbed into the ground — floods are the result. Rainwater running off roads is often polluted.

The rain garden deals with living plants rather than hard surfaces. Plants are designed to hold water and release it slowly, either into the ground, to be absorbed by plant roots (and so eventually back up into the atmosphere) or to go down into the water table. Not only does the rain garden reduce the amount of water that flows onto the street, but it helps to clean it plants are very good at breaking down pollutants(虧染物).
