5 WASTEWATER TREATMENT PLANT Conveyance System Conveyance System: 4 km of new pipe Four new lift stations: 1. First Dock 2. Main St 3. First St near Arnet Rd 4. Pacific Rim Highway near Gas n Go station 6

6 Outfall The new proposed outfall: will be 500m long will be made of 350mm HDPE DR17 will include a set of diffusers at a depth of 31.3m (relative to chart datum) The existing outfall at the end of First Street will be abandoned. 7

7 Residual solids Facility The facility will consist of a biosolids/wood waste blend. It will be 20m x 75m (65 ft x 240 ft) Current design consists of: Aerated bin Agitated bed composting Aerated Channel Composting Wood Waste storage Curing Process Pictured Here: Ladysmith solids handling facility. About twice the size proposed 8

8 Previous Cost Estimates Liquid Waste Management Plan November 2017 Project Component Base Cost TOTAL Wastewater Treatment Plant $ 12,700,000 $ 12,700,000 Conveyance including Outfall $ 5,700,000 $ 5,700,000 Solids Handling Facility $ 2,500,000 $ 2,500,000 Upgrades and Others $ 800,000 $ 800,000 $ 21,700,000 What changed? Population projection changed from 5,300 to 10,000 (yr 2038 to account for seasonal population Current market conditions are strong for Vancouver Island contractors and cost of materials are rising. Sample analysis on sewage revealed stronger than anticipated levels of BOD as high as 400mg/L. Typical residential strength is 200 mg/l Additional concrete required for Tofino seismic conditions Pre-Design Stage, Class 'C' Cost Estimate March 2018 Project Component Base Cost Contingency TOTAL Wastewater Treatment $ 23,300,000 $ 8,200,000 (35%) $ 31,500,000 Plant Conveyance $ 6,900,000 $ 2,400,000 (35%) $ 9,300,000 Outfall $ 603,000 $ 181,000 (30%) $ 784,000 Solids Handling Facility $ 1,770,000 $ 530,000 (30%) $ 2,300,000 $ 43,884,000 60% Design Stage, Draft Class 'B' Cost Estimate June 2018 What changed?

Compounded 6% 10% Design Allowance: For detail revisions between current pre-design drawings to final, tender-ready drawings. Compounded 12% 6% Escalation Allowance: For the rising costs of construction and remoteness anticipated between June 2018 and a tender date in Compounded 8% 10% Construction Allowance: For hidden conditions onsite and change orders.

11 Financial Implications Annual Operating Costs Operating Costs: Operating the wastewater treatment plant will significantly increase the sewer component of utility bills. Current information indicates that this will be as much as a 91% increase. Current Annual Sewer Charge Total New Charge (+91%) Average Residential Customer (216 m 3 ) Residential with B&B (274 m 3 ) Commercial Recreation (600 m 3 ) $290 $554 $417 $796 $984 $1,879 Commercial Hotel (15,170 m 3 ) $21,382 $40,840 12
