Short Description:
The Town of Oliver completed a multi-year water-safety project, while achieving significant efficiency improvements and innovative financing through development cost charges. In 1989, the Province of BC dissolved the Southern Okanagan Lands Irrigation District and transferred the open canal, pumps and rural water distribution mains to the Town. Unfortunately, this water received minimal treatment with simple chlorination, creating several concerns:
• Taste and odour 
• Inadequate chlorine contact time 
• Chlorine-resistant parasites 
• High chlorine demands 
• Trihalomethane risks 
• Pesticide over-spray, agricultural runoff, and fecal contamination risks in open canal Separate mains were installed for domestic water.

All new connections in the improvement area were metered. Additional conservation measures included use of reclaimed water. These conservation measures have reduced chlorine requirements by 49 tonnes per year and domestic water demands by 25%.  In recognition of these savings, Oliver collects development cost. Oliver is the only jurisdiction in BC with Provincial approval for this funding approach.
