1. 1 Sechelt Water Resource Centre Operational Report 26 August 2015

2. 2 Milestones  First Water 7 January  Full flow 20 January  First Ultra Filtration water 7 March  First dewatered biosolids 19 March  Performance Test start 27 March  Performance Test completion 9 May  Fully commissioned 25 May

3. 3 Public Concerns About Flow and Capacity RFP Sep 2012 – five year average flow 2100cu.m/day Design capacity of 4000 cu.m/day Vancouver Sun, 18 April 2013 “the retired engineering professor believes that within a few years of the new plant's scheduled completion in September 2014, Sechelt will need capacity for treating 5,500 cubic metres of sewage each day.” "My major concern is that I think they have done a lousy job of measuring the flow of grey water (the sewage that goes into the plant). To me, the flow number is blatantly and absolutely incorrect."

4. 4 Flow  Average daily flow Jan- March 2330 cu.m/day  Apr- June 2130 cu.m/day  July 2150 cu.m/day  August 2020 cu.m/day  Highest recorded flow 2663 10 Feb 2015  Lowest recorded 1889 Sun 23 August

9. 9 Biosolids  Centrifuge dewatering to 20% solids  Average production 2 tons per day  1.5 to 2 truckloads per week  meeting all the metals requirements for Class A compost

10. 10

11. 11 Biosolids Composting by Salish Soils  Trials at Dusty Rd since March  Good pile heating  Approx 2:1 ratio woodchips to biosolids  Moving offsite end of September  Expect first Class A Product in October  Available for sale in 2016

24. 24 Dusty Rd Septage  New septage station working well, mostly  Lots of gravel and rocks in septage  Volumes down from 2014  Lagoon sludge pumping by Sylvis from April to Sept  Geotube dewatering to start in September

25. 25 Labour  More operator time required than Ebbtide and dusty  More lab work  Lots of after hours callouts  = overtime  Causes of callouts being analysed and gradually resolved.

26. 26 Odour and Noise  Meets all noise requirements  Odour performance generally very good.  Odour control unit down from Friday 21 Aug to 26 Aug – some odours outside of building

27. 27 Summary  Effluent quality outstanding  Biosolids production less than expected  Operating costs stabilising  Still finding and resolving “bugs”  More challenging and rewarding to operate than the old plants
