1 Design-build of packaged water treatment for small communities Mike Beeney, Technical Sales BI Pure Water, Inc. Surrey, BC, Canada

2 Potable Water Health Problems A number of issues exist with FN drinking water: Many treatment plants are outdated or are undersized for growing communities. Hundreds of Boil Water Notices exist for the main treatment plants across Canada. Boiling doesn t remove dangerous items like Arsenic or Manganese. Residents need to resort to expensive and inconvenient bottled water. Small groups of residences are beyond the distribution pipeline and not served.

3 Challenges Additional challenges that add to the problems: Many of the treatment plants are located in remote areas so it is difficult to bring in supplies. Often the community wasn t consulted as to their primary water needs. Some plants are difficult to operate and cause water outages or downtime. Operator training is often difficult to fund. Many plants don t have remote monitoring.

4 Challenges Some are daily: Waiting for the school busses to cross

5 Potable Water Solutions New solutions are being developed: Community Circle approach to gathering information and defining the needs of the residents. Cost and time savings by delivering standardized treatment systems. Modern communications and remote monitoring allows operator to watch the plant on a cell phone. Design-Build approach to supplying the treatment systems vs the old Design-Tender-Build method.

6 Design-build vs traditional project bidding

7 Examples of First Nations & Remote Water Treatment Plants Design-Build Examples 1. Cambridge Bay, NU 2. Kugaaruk, NU 3. Kugluktuk, NU 4. Iqaluit, NU 5. Gilford Island, BC 6. Lytton, BC 7. Ymir, BC (Small community) 8. Laketown, BC 9. Little Saskatchewan, MB

8 Laketown, BC Saik uz FN Custom system designed & manufactured to remove radon from well water $200,000 in 2005 / 20 USGPM Radon removal tank

9 Gilford Island, BC Kwicksutaineuk First Nation Water Treatment Plant Difficult combination of lack of water, excessive hardness, total dissolved solids, iron/ manganese and microbiological contaminants in wells Tested 4 different RO units Final package plant barged then skidded to location

10 Gilford Island, BC Very remote with no road access Package Water Treatment Plant

11 Nickeyeah #25, Lytton, BC Long standing boil water advisory/river turbidity addressed with filtration, UV and minimum of chlorination *Community Circles approach

12 Ymir, BC LEED-certified Green Package Water Treatment Plant Designed for community desires to reduce the carbon footprint and environmental impact, conserve energy, use local resources to build, and serve over the long-term growth of the community.

13 Little Saskatchewan First Nation, Manitoba Very difficult water requiring Reverse Osmosis water treatment unit on a skid to go into existing building Cost $76,000 in 2014

14 Cambridge Bay, Nunavut Home of new Canadian High Arctic Research Station Package Water Treatment Plant travelled approx 5000 km by road, Mackenzie River barge, and icebreaker to Northwest Passage community Delivering 20 Litres per second (317 USGPM) to community & services Silt in the raw water is a problem during the melting season and into summer. Other challenges include the need to minimize consumables in high arctic environment where nothing decomposes

15 Kugaaruk, Nunavut Truckfill water treatment plant Two identical treatment trains, delivering 1,134 L/min lake water to the two truckfill stations. Cartridge filters, UV radiation and chlorination treatment

16 Kugluktuk, Nunavut Water treatment system on skids To augment existing plant and address turbidity in the Coppermine River supply which is above the allowable limit GPM, CFS then Slow sand filters

17 Iqaluit, Nunavut Package Fire Pumphouse Diesel pump with backup battery Delivers up to 1500 psi Fully tested then delivered. Inside method of testing flow all year

18 Design Your Water Treatment System Vernon, BC 1. Meet with Elders and Council to assess community needs 2. Determine Operator needs 3. Engineering 4. Design (exterior) 5. Design low maintenance system 6. Programming 7. Remote monitoring 8. Commissioning, training, servicing 9. Package sewage treatment plants 10.Potable water regulations

19 Potable Water Requirements Water suppliers are required to provide long term plans to reach the goals of: 99.99% inactivation of viruses - Bugs 99.9% removal or inactivation of Giardia Lamlia and Cryptosporidium - Cysts Two treatment processes for all surface drinking water systems 0.1 NTU Turbidity - Water clarity Zero tolerance for total and fecal coliforms and E.Coli Worst bugs

20 Designing your plant: Study the community need & water source TL'AZT'EN NATION council, elders, band members, design engineers, researchers RESEAU-Water NET and INAC were involved in the design of Middle River, BC s new water treatment plant. Pilot Test the water source Ask for community concerns/feedback: Community Circle approach RES EAU Pilot test van at Middle River

21 Designing your plant: Understand the operator s needs Middle River Operator Gammale

22 Designing your plant: Engineering plan Involves treatment plant operators, design engineers, INAC

23 Designing your plant: Building fabrication at the factory Custom building/csa building Container Skid mounted for existing building Or modified container?

24 Designing your plant: Easy to use, low maintenance equipment Blue Filters and UV unit on the right *Separate chlorine room from control room, with safety shower/eyewash Lytton Operator Warren Brown says at first he thought the equipment looked complex but once he started to use it found the plant to be very easy to run

25 Designing your plant: Programming The entire water treatment system can be run & monitored by computer Optional remote monitoring/ support with addition of a modem Operators help design the interface Screens can be changed to better display info Client becomes part of design

26 Designing your plant: New advancements in technology allow remote monitoring & plant control by cell phone or tablet Operator can see plant operations

27 Designing your plant: Shipping, Commissioning, Operator Training, Servicing

28 Package sewage treatment systems MBBR and MBRs allow water reuse of sewage treatment Treat sewage and recover bacteria and pathogen free water for community fire stations, as well as irrigation. About $320,000 for the first 100 dwellings. Serve additional persons by adding more package buildings

29 Treatment Plant Servicing and Replacement Parts Design-builders in general should have ability to service plants over long term and provide correct replacement parts Design-builders can remotely support the operator with proper electronics.
