Environmental Drainage

Today the use of Sustainable Drainage Systems and Rainwater Harvesting are environmentally friendly ways of dealing with surface water run off.

Sustainable Urban Drainage Systems (SUDS).

There are many different Sustainable Urban Drainage Systems and their design and application mean they can be applied from hard surface areas though to soft landscape. The variety of design options available allow designers and planners to consider the land use and address flood control, storm water management and pollution whilst working with the environment.

Infiltration and attenuation systems gradually return collected surface water to the environment, they may include a storage element that allows storm water to be captured and the released over an extended period, acting on the same principles as a soak away. These can be used on both domestic and commercial properties as alternatives to piped to sewer solutions.

Rainwater Harvesting.

Water supply and storm-water management has become a greater problem in recent years and the issues raised need to be addressed on many new developments. Rainwater is often considered a problem because it needs to be drained and disposed of as quickly as possible. Rainwater harvesting Addresses this problem by retaining the water for future use. The retained water cannot be used as drinking water but can substitute mains water for many other purposes, such as cleaning , irrigation, fire fighting and toilet use.

Rainwater Harvesting systems work on the concept that water is first collected and filtered and than stored. The water can then be pumped to the point of use or to an internal break tank. If the system runs low on rainwater, the supply is maintained by a mains water back up unit. When rainwater is once more available the system automatically changes back to using the rainwater.

In order to calculate the size of system required the volume of water that can be collected needs to be compared against the water needed.
