This powerpoint presentation outlines energy efficiency for ultraviolet (UV) treatment facilities in British Columbia. Water treatment objectives include: tightening water quality standards (Interior Health Authority) to 4 log viruses inactivation, 3 log Giardia/Cryptosporidium inactivation, dual treatment, turbidity to GCDWQ (< 1.0 NTU), and zero total and fecal coliform; treatment approach involves microbial protection using UV disinfection (validated at 40mJ/cm²), maintaining residual disinfection and providing and planning for future filtration. Vernon Mission Hill WTP is presented, along with Naramata WTP, and Kelowna - Poplar Point. Topics covered include: Water Demand Reduction; UV Equipment Procurement Strategies; UV Equipment Procurement Annual Maintenance Items; Life Cycle Cost Results; Improving UV Operational Efficiencies; Lake Source Heat Recovery; HVAC Operator Interface Graphic for Vernon; Vernon Heat Pump Performance; and, Other Sustainable Design Initiatives. Includes tables, figures.
