WASTE WATER IS A VALUABLE RESOURCE
At CRESS WATER SOLUTIONS we are keen to promote the notion that the cleaned effluent from a reed-bed system is a resource of secondary quality water that can be recycled for a variety of purposes.
Our reed-bed and wetland systems can be designed to produce a very high quality effluent which can be used to fill a large pond or small lake forming the centrepiece of an ecologically balanced ornamental water garden, or a small wildlife sanctuary on the farm. Such a pond or lake can be used as a reservoir in which large volumes of water can be stored for recycling.
Since the water in the pond is constantly being replenished from the reed-bed system excess water will have to flow away to a stream or some form of soakaway. The top water level will always be maintained. Provided demand is matched by supply the chances of the pond being pumped dry are remote.
Rainwater drained directly off roofs, or overflowing from the rainwater harvesting tank, and storm water run-off from other hard surfaces can be redirected into these ponds. Not only will they help to keep the ponds topped up but they could add to the volume of water stored and available for re-cycling.
As mentioned above, secondary quality water can be used in the irrigation of orchards or flower gardens, recycling into the home to flush toilets or for washing the car. In fact, if the appropriate additional treatment is carried out, this water could be used for almost any purpose.
In agricultural or industrial applications, the potential for re-use (for instance cooling) is excellent and is a viable economic alternative to the many wasteful throw-away methods currently in use.
Treated wastewater from a reed-bed is not only a resource of water it is also nutrient rich containing nitrites, nitrates and phosphates. Where the space is available this water can be used to promote the growth of willow plantations, which can be coppiced for firewood, amongst other uses. In the process the nutrient levels are reduced further and near river quality water can be produced.
