Preventing Pollution
By preventing pollutants from entering surface water and groundwater, our rivers, lakes, reservoirs and aquifers will continue to provide freshwater. Chemical and oil spills, and leachates from ground contamination are the major threats to freshwater. Bunding potential liquid pollutants, monitoring effluent, reducing discharges, using cleaner production techniques and ensuring proper waste disposal are some of the measures to prevent pollution.
Choice of water
Grey water recycling consists of harvesting rainwater from the roof, filtering and storing it for later use and recycling water that has already been used.
Grey water suffers from images of filthy waste from washing machines. Yet, correctly treated grey water is as clean and clear as the water you would find in a swimming pool - something most people have no qualms about jumping into. This is more than adequate to flush the toilet. More from Water Dynamics
Conserving Water
The Water Supply Regulations in England and Wales put in place some very simple and practical solutions for conserving water. These are reduction measures and include limiting all newly installed WC's to a 6 litre maximum.
A simple audit identifying where and how water is used will give ideas for conserving water. These could include auto shut-off devises on hoses & taps, mending leaks, reducing quantities, preventing over-flows. WaterNet Toolkit provides all sorts of ideas and case studies for all sectors
Managing flow
Both drought and flooding are becoming common occurrences. Managing flow helps to alleviate these by ensuring supply to drought areas and preventing flooding. Consider your surroundings, potential flash floods can be reduced by trees and underplanting. Water storage systems and leak control in the supply infrastructure can help reduce the affects of drought. SWEL
