5 Drinking Water System

6 Water System Background CRD Service since 1980 Service area is about 390 Hectares Includes 1,206 Parcels (in 2015) of which 1,012 are serviced Water Supply from Buck Lake and Magic Lake Treatment plant includes pre-treatment, DAF, filtration, chlorine and UV Two steel storage tanks (340 and 750 m3) 27 km distribution mains primarily 150mm dia. 135 fire hydrants/standpipes, 6 PRV s, and 217 valves

7 Drinking Water Production and Demand Magic Lake Estates Monthly Water Production Volume (m 3 ) Total water produced in 2015 was 164,409 m3 (19% lower than 2014) Noticeable drop after conservation notice issued in July

8 Drinking Water Production and Demand Magic Lake Estates Annual Water Production and Demand Water Production Volume (m 3 ) 250, , , , , , , , , , , ,330 Water Demand 164, ,940 50, In 2015 a total of 164,409 m3 raw water was extracted from Buck and Magic Lakes (80% Buck / 20% Magic) Total customer usage (demand) was 113,940 m3

9 Drinking Water Production and Demand Water Production decreased by 19% from 2014 and 14% reduction from 5-year average Water Demand decreased by 7% from 2014 and 9% reduction from 5-year average Possible Reasons for downward trend on demand: Consumption-based billing initiated in 2013 Conservation notices Increased public awareness

10 Drinking Water Production and Demand Water Loss / Non-Revenue Water Production in 2015 was about 31% (down from 43% in 2014) Operational Use: Automatic flushing units Manual flushing Frigate tank commissioning (filling/draining) Fire Protection Use: Hydrant maintenance and exercising Fire department use as needed System Losses: Pipe network leakage (fitting, joints, etc.) Water main breaks Water service leakage

11 Drinking Water Quality

12 Drinking Water Quality Raw Water Buck and Magic Lakes exhibited low concentrations of total coliform and E.coli bacteria. Both lakes exhibit elevated iron and manganese concentrations, which spiked in the summer for Magic Lake and in the fall for Buck Lake. Treated Water Treated water was bacteriologically safe to drink. Treated water turbidity was well below the guidelines limits.

13 Drinking Water Quality Total organic carbon (TOC) was lower than historical levels but at 4.4 mg/l still a strong precursor for disinfection by-product formation. Disinfection by-products (THM and HAA) did not exceed the guideline limits. All metals were below maximum acceptable concentration limits. Water sources were subject to algal blooms that periodically affected taste and odour of the drinking water.

14 Drinking Water Quality Water quality data is posted on the CRD website:

15 Drinking Water Operations 2015 Significant Events and Activities Water treatment plant optimisation Commissioning of potassium permanganate system Annual intake inspection on Buck and Magic Lakes More extensive watermain flushing Fire hydrant and water leak repairs Air valve replacement Installed three new water connections

16 Water System Capital Improvements

17 Water System Capital Improvements New water treatment plant, raw water pump stations, Frigate storage tank, and watermains commissioned in

18 Grand Opening Event - May 23, 2015 Public tours of the water treatment plant

19 2015 Water System Capital Improvements Spillway log boom installed on Magic Lake - Complete Air valve replacement on distribution system - Complete Signal Hill PRV Upgrade - Design Commenced Buck Lake building alterations - Complete All projects were completed within the overall approved budget

20 Future Capital Improvements ( ) Year Improvement Budget 2016 Eyewash Station $8, Buck Lake East Dam Detailed Design $120, Schooner PRV Upgrade $100, Electrical Power to Storage Building $8, Buck Lake Intake Line Assessment $5, Capstan Way PRV Upgrade $100, Public Engagement/Referendum on Future Projects $20, Buck Lake East Dam Remediation $1,000, Watermain Replacement Program Phase 2 $425, Watermain Replacement Program Phase 3 $400, Watermain Replacement Program Phase 4 $400, projects to be considered at the MLE Committee Pre- Budget Meeting (Fall 2016)

21 Sewer System

22 Sewer System Background CRD Service since 1980 Service area is about 210 Hectares Includes 714 Parcels (in 2015) of which 623 are serviced 6 pump stations and 316 manholes 16km of sewer pipe mm dia. (about 45% AC) Treatment plants: extended aeration, UV disinfection Outfalls: 150mm dia.; 200m long; m below ocean surface in Swanson Channel

23 Schooner and Cannon Treatment Plant Flows MLE Annual Wastewater Discharge 100,000 90,000 80,000 70,000 17,249 17,504 14,831 16,003 15,119 volume (m 3 ) 60,000 50,000 40,000 30,000 72,001 72,363 67,069 78,868 74,459 20,000 10, Schooner Cannon Total 2015 discharge was 89,578 m 3 (6% lower than 2014) Annual flows are influenced by precipitation

24 Schooner and Cannon Permit Compliance Schooner & Cannon WWTP Flow Exceedances Flow Exceedances per year Annual Precipitation (mm) Schooner WWTP (2008 permit 350 cu.m/d) Cannon WWTP (permit 68.2 cu.m/d) Annual Precipitation (mm) Both plants operate over their permitted/operational capacities during wet weather flow Measured effluent quality limits did not exceed permit values, but likely out of compliance during peak flow

25 Outfall/Surface Water Monitoring Locations Sampling required every 4 years, unless 3 consecutive day flow exceedance in winter or 1 day in summer Flow exceedances from Feb 6-10, 2016 triggered sampling Results were within acceptable limits Next sampling scheduled for 2020

26 Sewer System Operations 2015 Significant Events and Activities Temporary hauling of septage from Chart Drive Annual flushing of sewers around Buck Lake. Cutlass pump station electrical upgrades. Multiple callouts to pump station electrical trip-outs caused by clogging rags. Installed two new service connections

27 Wastewater System Capital Improvements June 2015 referendum to borrow $6.05M for wastewater improvements was not approved. CRD and Committee worked to develop phased approach. Phase 1 is $1.56M and includes: Chart Drive Replacement 325 m Pipe Replacement along Buck Lake 117 m Pipe Replacement on Privateers Rd Inflow & Infiltration Reduction Program Schooner WWTP Steel Tank Condition Assessment

28 Sewer System Infrastructure Public Open House on Feb. 27, 2016 AAP closed on March 31, 2016 and was approved Chart Drive design completed, tender issued, construction started in June 2016 On time and within budget Other Phase 1 projects will commence in 2016 and be complete in 2017
