Subdivided Strata: Queenswood Wastewater Treatment

by MSR Solutions | Apr 2, 2021 | Wastewater Treatment

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.

History of Queenswood and Cadboro Bay

Queenswood is a street, as well as a neighbourhood in Cadboro Bay in Saanich

Cadboro Bay was the site of Sungayka, a village of the Songhees Nation 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.

by MSR Solutions | Mar 20, 2021 | Civil Engineering, Land Development, Uncategorized, Wastewater Treatment, Water Treatment

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.

Construction completed March 20, 2021.

The Salt Spring Island Farmland Trust is raising funds to build, The Root – Centre for Food Security, at 189 Beddis Road.

“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.”

Prospect Lake: Upgrade to residential wastewater treatment

by MSR Solutions | Feb 23, 2021 | Wastewater Treatment

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 Lake in 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 Water Treatment System

by MSR Solutions | Jan 18, 2021 | Wastewater Treatment, Water Treatment

Fircrest RV Resort retained 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 approximately 7.5 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 Resort proposed 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.

Fircrest Upgrades

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.

Onsite Wastewater System Upgrade: Nanaimo Regional Airport

by MSR Solutions | Oct 13, 2020 | Operations and Maintenance, Wastewater Treatment

The Nanaimo Airport Commission (NAC) operates the Nanaimo Regional Airport. They have their own wastewater treatment and disposal on-site. NAC determined the wastewater system was in need of improvements. Odour concerns and increasing operational demands could impact regulatory compliance. A rapid increase in passenger demand in recent years also warranted an analysis of the capacity of the system. MSR Solutions reviewed the existing treatment system. We proposed upgrades to resolve the current issues and also improve capacity to meet future demands.

Wastewater Issues and Improvements

The existing wastewater treatment system at the Nanaimo Regional Airport had solids loading and equipment issues. These contributed to excessive maintenance costs and nuisance odours. In addition, increased passenger demands created a need for modifications to the wastewater system. These improvements increased capacity and reliability. MSR Solutions proposed the following improvements:

Reroute all collection piping directly into the existing lift station
Extend the gravity main from the new terminal building to the existing lift station
Replace the solids handling pumps in the existing lift station with grinder pumps
Install a 5,100 imp gal (23,100 L) Dan’s Precast equalization tank
Relocate the MicroFAST media to a new treatment location. In addition, we proposed installation of timer controlled pumps inside the new tanks to transfer sludge to an aerobic digestion tank.
Install a 3,560 gal (16,100 L) Dan’s Precast septic tank with air pumps and diffusers for aerobic sludge digestion.
Decommission the existing septic and MicroFAST tanks

Operation Complete

Information about the repairs and improved capacity of the current system went to The Ministry of the Environment. The wastewater system upgrade allows the airport to handle peak flow until 2028 without exceeding the maximum allowable discharge under the Registration. It also allows airport operations under its current Registration until flows become too great and they require additional capacity. The Ministry of the Environment received the filing in August. Construction was subsequently completed this fall with MSR provided field inspection. In February, MSR provided operator training and review of the O&M manual.

Grey Water Treatment: Croftonbrook Phase 2

by MSR Solutions | Oct 9, 2020 | Operations and Maintenance, Wastewater Treatment, Water Treatment

Phase 2 of the Croftonbook project is now underway. MSR Solutions Inc. is currently providing a review of the proposed grey water treatment and reuse system for Phase 2 of the Croftonbrook facilities on Salt Spring Island. They are also looking at capturing rainwater as an alternative water supply.

Grey Water and Water Conservation

Potable water comes from an onsite well. In order to conserve water, it has been proposed to use recycled grey water and captured rainwater to supply toilets in the new living units.

About Croftonbrook

Island Women Against Violence (IWAV) owns and operates Croftonbrook. It provides 20 units of subsidized rental housing for seniors and people with disabilities. In response to the serious housing shortage in the community, IWAV proposed a 2-phase development to add 54 new rental units.

This is mixed model housing, so rentals will be available to individuals, couples and small families with low to moderate incomes. Some of the units will be provided for people who are experiencing homelessness.

Croftonbrook provides independent supportive living for seniors and people with disabilities. The Phase 2 development involves the construction of a new two-story building. It will have twenty-two, one bedroom living units, with laundry facilities on each floor.

The Croftonbrook development has received capital funding through the CRD Regional Housing First Program. This is a partnership with CRD, BC Housing and Island Health. The Salt Spring Island Foundation has also provided a grant to support the water system design.
