1 SECHELT WATER RESOURCE CENTRE March 19, 2015 Councillor Karen Skadsheim I visited the plant with Sechelt Councillors, Alice Lutes and Darren Inkster. The tour was led by Project Co-ordinator Paul Nash who will be giving a workshop on Wastewater Treatment & Resource Recovery Advances at the upcoming AVICC in Courtenay April Sechelt began their LWMP process in 1997, one year before Powell River, and completed it in Timeline: LWMP Dec 2011 Gas Tax Funding Jan 2012 Request for Expressions of Interest Mar 2012 Project Steering Committee TENDER FORMAT: DESIGN-BUILD Request for Proposals Sep 2012 RFP issued Dec 2012 Evaluation & decision Mar 2014 Referendum on GMF Funding Nov 2014 In-service date Funding Sources (see also Funding Options comparison slide): Building Canada Fund (2010) $3.2MM Gas Tax Innovations Fund (2012) $8.0MM GMF Grant (2014) $1.0MM GMF Loan (2014) $7.4MM Sechelt Indian Government District $1.7MM District of Sechelt Sewer Reserves $3.6MM TOTAL: $24.9MM The GMF loan is 10-year low interest (2.25%) and the $1MM grant more than covers the interest on the loan.

2 Sechelt went with Design-Build which allowed proponents to bring various technology options so long as they fulfilled the system evaluation criteria: MANDATORY REQUISITES (pass/fail) Effluent quality, LEED Gold standard, noise, odour QUALITATIVE FACTORS Weighted technical criteria (quality assurance, safety, etc) 59% Innovation 11% Business Opportunity (what could come out of this to create economic opportunity for the community) 8% Aesthetics 3% O&M Costs 30 year NPV 11%* Capital Cost 9% (this is unusually low) * In this case, the builder is tied to financial penalties if the O&M costs exceed 15% of what was planned at the proposal stage and so is tied into the ongoing success of the project. In the end, they had 5 proposals that met the criteria and interestingly enough, the top 2 proposals were apparently extremely different from each other. A guiding philosophy behind the project is that water is a resource, hence the name of the facility is the Sechelt Water Resource Facility. The facility meets new federal standards, creates re-use opportunities for biosolids and water, and is a showcase with educational opportunities to connect community members and show that there is no away for waste.

3 Sechelt had two possible sites and allowed the proponents to choose which one was most suitable for their proposal. Both had residential properties on 3 sides so the project required a facility that would not devalue neighbouring properties. The project also required keeping the existing plants operational during construction, which I think will be the case for ours as well. The successful proponent was Urban Systems who brought forward the Organica Fed Batch Reactor (FBR) system. This was developed in Hungary and is relatively new to North America, but has been in successful operation in Europe and Asia for over ten years. The FBR system adds air and microbes digest the waste in water. The advantage is that you have roots that hang down in the wastewater and as the microbes digest the waste in the water, they float around and in addition to the biomass, you get a fixed film: different organisms that attach to the root systems and can further help digest the wastewater. The effect is that it actually shrinks the footprint of the facility; however, there are other ways to accomplish this. Technical performance standards: The Sechelt Water Resource Centre is the first plant built to meet the new Indirect Potable Reuse standard of treatment the highest level of treatment in BC. Sechelt is also working on a Biochar Project from wastewater biosolids and then use the resulting biochar (a form of charcoal) to filter the treated wastewater effluent. The expected oucome is that the charcoaling process will destroy the contaminants in the biosolids and the resulting biochar will remove the contaminants from the water. There is a possibility that biochar could be an economic opportunity also.

4 The Water Resource Centre brings Sechelt: an end to the noise and odour from the Ebbtide plant a cleaner offshore environment with ten times less waste solids discharged into Trail Bay double our existing treatment capacity to meet projected needs for the next 20 years a treatment system that is more cost efficient to operate an active use park on the site consistent with the adjacent recreation and residential areas reuse of resources (biosolids, heat, reclaimed water) that were once wasted. Water Resource Centre Fast Facts: Treatment Capacity Average day flow: 4000 cubic metres per day (Current system: 2200 cubic metres per day) Peak flow: 6000 cubic metres per day Peak hourly flow: 500 cubic metres per hour (12,000 cubic metres per day) Population Capacity: 14,000 people (Current system connected population: 6,000 people) Future Expansion Capability: to 8000 cubic metres per day or population of 28,000 people Tankage Capacity Influent Holding: 907 cubic metres Batch Reactors: 4 X 1000 cubic metres Secondary Equalization: 400 cubic metres Sludge Holding: 400 cubic metres Treatment Primary: 6mm Fine Screens, cyclonic grit separation Secondary: Organica Fed Batch Reactor Tertiary: Membrane Filtration to 20nm ( mm) Disinfection: Ultra Violet Biosolids Treatment: Dewatering by centrifuge to 20% solids and composting to Class A compost (by Salish Soils) Effluent Quality BC Indirect Potable Reuse standard Suspended Solids > 5 mg/l Biochemical Oxygen Demand >5mg/L Turbidity < 1 NTU/L Coliforms median <1 CFU/100mL Effluent Disposal Using of existing ocean outfall in Trail Bay when not reused. Effluent is suitable for reuse for industry, park irrigation and agriculture.

6 TOUR PHOTOS:

7 Three of the FBR bays at SWRC. Only two are active at the moment, and the plants are still very young.

8 An active FBR. The water level is raised to fill the bay up to the level of the plant roots, then the aeration is shut off and slowly drained. The odour was minimal.

9 This FBR bay is not yet commissioned. On the floor, you see the aeration pads which contain thousands of tiny holes. Essentially, these are pinprick holes and are only open so long as air is forced through them. Once the air is shut off, they close up so there is no danger of clogging. At the top of the photo you can see the homes, literally right across the street. This is a residential crescent.

10 If there weren t labels on the jars, you would not be able to tell which was which.
