C.3 POTABLE WATER QUANTITY AND SUPPLY OBJECTIVES AND POLICIES 
 
Background Note:  The  objectives  and  policies  in  this  Section  pertain  to  water  quantity  only.  
Objectives and Policies about water quality are in Part A. 
 
 
C.3.1.1 GENERAL OBJECTIVE 
 
C.3.1.1.1 To apply  the precautionary principle  in ensuring that the density  and  intensity  of land use is  not 
increased in areas which are known to have concerns with the supply of potable water. 
 
C.3.1.1.2 To acknowledge that the surface water supply sources on the island are finite and remain under 
Provincial  control  and  that  more  effective  use,  management  and  sharing  of  the  resource  should 
be encouraged to support present commitments and future desired land use decisions. 
 
C.3.1.2 GENERAL POLICIES 
 
C.3.1.2.1 The Local Trust Committee will continue to support and participate in the Salt Spring Island Water 
Council. 
 
C.3.2 Community Water Systems 
 
Background Note:   Map  6  shows  the  boundaries  of  the  island's  community  water  systems  and 
their water sources. 
 
 
C.3.2.1 OBJECTIVES 
 
C.3.2.1.1 To ensure that the potential water demand of development within community water systems does 
not exceed the licensed capacity, or the amount of water that can be safely withdrawn from each 
system's water source. 
 
C.3.2.1.2 To reduce, delay or avoid the impacts of withdrawing additional water from surface water bodies. 
 
C.3.2.1.3 To ensure that zoning changes in the North Salt Spring Waterworks District do not result in such 
a level of development that water  cannot be supplied to needed  public facilities or  would not  be 
available  for firefighting  purposes.    In  particular,  to  ensure  that  water remains  available  for 
hospital and school expansion, and affordable housing. 
 
C.3.2.1.4 To encourage a variety of conservation methods in all community water systems 
 
C.3.2.1.5 To  ensure  that  zoning  changes  within  the  boundaries  of  water  systems  do  not  result  in  such  a 
level of demand on island water sources that agricultural activities cannot obtain water.
