The Sunshine Coast Regional District (SCRD) has retained MSR Solutions Inc. to design a system to replace the existing recirculating sand filter (RSF) due to apparent ineffectiveness of current performance. The system is located at the Woodcreek Park Wastewater Treatment Plant (WWTP) in the Woodcreek Park residential neighborhood of Electoral Area E, Sunshine Coast Regional District. The system serves 74 homes under Permit # PE-04183 issued under the Municipal Wastewater Regulation (MWR) by the Ministry of Environment (MoE). Under the permit, maximum daily discharge shall not exceed 75 m3/day, TSS shall not exceed 45 mg/L, and BOD5 shall not exceed 45 mg/L.
Investigations of available data and a site inspection note the recirculating filter is effectively plugged and in need of remediation or replacement. Other works were noted as either in need of improvement (headworks) or replacement (recirculation tank mixers/aerators), and site constraints leave little area available for replacement of a similar structure without removal of the filter.
MSR examined alternative systems included replacement of the filter with the same, and secondary treatment options previously reviewed by the SCRD. In addition to the treatment options prior to disposal, we have recommended improvements to the inlet piping to minimize solids plugging and to improve flow distribution.

MSR Solutions Inc. (MSRS) was hired by Three Point Properties Ltd. and its affiliated companies for developing a Community Wastewater Treatment System, henceforth called “the Lighthouse Wastewater Treatment System”, for the various developments within the area. Further to completion of the desktop study, MSRS has been retained by the Client to “Register” the Lighthouse Wastewater Treatment System with the BC Ministry of Environment and Climate Change Strategy (ENV) under the Municipal Wastewater Regulation (MWR), of the Environmental Management Act.
The development of the Lighthouse Wastewater Treatment System will be completed in two phases. Flow estimation for Phase 1 and 2 is estimated at around 133,00 and 311,000 (L/day), respectively.
The wastewater treatment plant consists of primary settling headworks, flow equalization, a membrane bioreactor (MBR) process, chemical and biological nutrient reductions, and effluent disinfection with ultraviolet (UV) light. The treatment system will provide a Class B effluent –i.e., BOD5 and TSS concentration of 10 (mg/L) or less and fecal coliform less than 400 [MPN/100(ml). The treated effluent will discharge into the wetland.
MSR Solutions upgraded the wastewater treatment and disposal system in the 2600 block of Queenswood Drive in Saanich. The 0.93-hectare property is now subdivided into two strata lots: Strata Lot A and B.
Strata Lot A covers 0.34 hectares of the divided property and has a five-bedroom house under construction. The house will require a wastewater treatment and disposal system.
Strata Lot B now has a four-bedroom house with a wastewater treatment and disposal system.
Registered Onsite Wastewater Practitioner (ROWP) Noel Nielson retained MSR Solutions Inc. (MSRS) on behalf of the developer Mark Williams. MSRS assisted with the Queenswood review and design of a wastewater treatment and disposal system. This was in compliance with the applicable regulatory requirements of the Island Health Authority (VIHA).
The BC Sewerage System Regulation (SSR) under the Public Health Act applies to the construction and maintenance of sewerage systems with a combined design daily domestic sewage flow of less than 22,700 L/day (5,000imp gal/day). The Queenswood Drive construction is complete and a Letter of Certification submitted to Island Health on March 29, 2021.
Cadboro Bay was the site of Sungayka, a village of the SongheesNation for some 8,000 years. Official relocated them to T Victoria’s Inner Harbour in the mid 1800s. The land between Gyro Park and Telegraph Bay is included in a Douglas Treaty. Cadboro Bay takes its name from Hudson’s Bay Company schooner to enter the bay, the Cabdoro.
Cadboro Bay also gives its name to the neighbourhood situated between the bay and the University of Victoria. The area is bounded by the Uplands to the south, Ten Mile Point to the east, and Queenswood to the north. At the heart of the neighbourhood is the local centre, Cadboro Bay Village.
MSR came in to create an onsite wastewater treatment and disposal system for a new project. The Root facilities are at 189 Beddis Road on Salt Spring Island.
A commercial kitchen and living residence will provide an estimated Daily Design Flow of 2560 L/d. The proposed treatment system consisted of extended primary treatment and secondary treatment with a package aerobic treatment system. This was followed by a tertiary treatment within a sub-surface engineered wetland. Moisture tolerant plants will cover the wetland disposal system which contains peat.
189 Beddis Road is a 0.6 ha (1.5 acre) property located on Salt Spring Island. The property contains two primary buildings. One for food storage with a commercial kitchen for processing local produce. the other is a two-bedroom caretaker apartment.
“The Root is a local food facility that will include a licensed teaching and processing kitchen, and temperature-controlled storage for local food, and the Seed Bank.
This means more local food will be available all year round. The certified Food Safe kitchen will be available to farmers and food processors as well as individuals and community organizations. Training programs such as chef certification, youth programs on agriculture, as well as food preparation and preservation education for the whole community will be provided at The Root.”
MSR Solutions was ask to assist in a residential wastewater treatment project at 5010 Echo Drive in Saanich, BC. This 0.3 ha residential property sits on the east edge of Prospect Lakein Saanich, BC.
Development planned for 5010 Echo Drive increases the number of bedrooms on the property. This addition will increase the number of people living on the property.
The upgrade was to support up to 3,800 L/d of sewage flows generated by the additional occupants. This is a new residential wastewater treatment and disposal system design.
The new treatment system produces advanced Type 2 effluent using a Whitewater package treatment system and an Emperor UV system. Micro-dosing will be provided to an infiltration bed disposal system consisting of perforated laterals in a gravel bed over top of a sand layer and native soil.
Construction was completed and final site inspection was done on February 23.
Letter of Certification submitted to Island Health on March 10, 2021.
Fircrest RV Resortretained the services of MSR Solutions to provide recommendation for a water system leading to the design and construction of the facilities and to obtain a Temporary Use Permit or TUP.
Fircrest Lakeside RV Resort lies approximately7.5 Km northwest of Lac La Hache, BC on Highway 97 North in the Cariboo Regional District. The Resort now consists of a mix of RV sites and cabins for a total of 104 units.
MSR Solutions reviewed the well capacity testing Report by Golder Associates (2009), along with other research reports to support the basis for a design solution. They determined the anticipated average and maximum water demands for sizing of the water system. MSR Solutions reviewed the water quality results and considered treatment options based on past project experience with similar water quality issues.
Meeting Water Quality Guidelines
Fircrest RV Resortproposed to use the original campground as a single water user development for up to 60 seasonal recreational vehicle sites on the old water system. This system consists of 50 mm polyethylene pipe and an operating pressure of about 280 kPa (40 psi). This is different from the current land zoning so FirCrest required a (TUP). As a condition of the TUP, the new water system had to ensure the existing well can meet current Canadian Drinking Water Quality Guidelines.
MSR Solutions addressed treatment and distribution options at FirCrest in the past. They also received some approvals for a fee simple development with the CRD as owners of the water system. However, due to various constraints within the CRD, MSR Solutions had to delay upgrade plans.
MSR Solutions Inc. supplied Fircrest RV Resort suggestions for upgrades to the systems to meet the Canadian drinking water quality objectives and the current microbiological objectives for groundwater in BC. The design of the treatment facilities service an equivalent of 60 RV sites under a TUP.
Water comes from the existing well using the existing well pump. The raw water is then pumped into the treatment building and into the filter area. This area has a nanofiltration package skid mounted system for hardness and TDS reduction.
This is followed by two one-micron poly pleat cartridges in parallel. Two sets of two Viqua SV10 UV modules provide disinfection and cyst removal.
Water entering the storage tank get a chlorine injection provided with level floats. Based on CT calculation, the chlorine solution of 1 mg/L combined with the water must flow into the 3,000 US gal Norwesco vertical storage tank to provide the required contact time to obtain 4-log disinfection of the water.
After the water has achieved 4-log disinfection, an inline booster pump, in conjunction with a pneumatic tank, pressurizes the treated water to the resort. This provides a peak demand of 20 USgpm at 40 psi. The treated water exits the water treatment building connected to the water distribution system. The proposed system achieves or exceeds the current microbiological parameters.
Water Treatment Plant Now Complete
Fircrest RV reached substantial completion of its water treatment system under Construction Permit No. CP2020-100506. MSR Solutions has requested an Operating Permit.
The water treatment plant is complete and operational. The plant is suitable for winter mode (lower demand) operation. The smaller, indoor storage tank is installed and operational. The large tank has an installation date of April, for use during summer mode (larger demand).
Construction completed by October 22, 2020 and met all permit requirements including adequate horizontal and vertical separations. Water quality results show treated water meets the required guidelines. MSR Solutions will address the connection to the distribution system in the spring of 2021.
