Water Usage and Demand

Unless compulsory water metering is installed it is doubtful that the water savings target figures used  in calculation for future demand will be achieved. 

There is a high risk that the data  provided by local councils in their Housing Plans will lead to under estimation of water usage. The housing plans neglect the dramatic increase in local infill housing over the last few years, and exclude the number of houses built under these small housing developments to date, and in the future. The actual population increase since the last census in 2011  is not known.

Due to leaving the EU there is the likely hood of increased manufacturing and farming in UK, and especially farming in the the South, due to favourable weather conditions. As a result there will be additional demand for water which should be included in the Plan.

Changes to reduce the use and disposal of plastics will increase the use and manufacture of reusable containers such as glass and metal, all requiring cleaning and serialisation eg milk bottles etc
This together with increase manufacture and recycling processes of cardboard for containers will increase water demand

Loss of Water Resources 

There is an increase threat to borehole water resources in the South Downs area due to pollution from fracking and farming etc
The zones of protect around these borehole should be reviewed with contingency plans in the event of loss of the resource and included in the supply and resources risk register.
The reduction of abstraction licences and  unknown future water quality changes may result in large reduction or total loss of a source .

Increase in Water Quality Requirements

Due to the unknown future changes in chemical and microbiological requirements some allowance should be allowed in the Plan to cover likely predicated requirements e.g. removal of pesticides etc
and the limitation on the supply.
