Kispiox Band Standpipe Water Storage Reservoir
 

Due to population growth in Kispiox, additional water storage was required to enable the water supply system to meet the community’s current and projected peak hour demands and to provide adequate storage for fire fighting purposes.

Dayton & Knight Ltd. completed a feasibility study investigating various options for providing the required storage. The options considered included standpipe reservoirs at various locations and conventional reservoirs located on elevated locations outside the village. A second standpipe reservoir located in the village above the new subdivision area was determined to be the most cost effective solution to meet the community’s current and future needs.

Dayton & Knight Ltd. completed the design and construction administration for the second standpipe reservoir. The project included construction of a 30m tall bolted steel standpipe tank, a control valve chamber, watermain connecting to the distribution system, an access road and miscellaneous site works. Modifications were made to the piping in the existing reservoir to enable
mixing of the stored water and a control valve chamber was installed to enable control over the filling of both reservoirs.

The water treatment plant operation is controlled based on the water levels in the reservoirs. The water level in both reservoirs is measured using ultrasonic sensors and the information sent via radio link to the water treatment plant. An uninterruptible power supply (UPS) was installed at the existing reservoir to power the level sensor and radio equipment to ensure level information is available in the event of a power outage. With the water treatment plant having auxiliary power, the water supply system is fully functional during a power outage.



Mount Shannon Reservoir, City of Chilliwack, BC
 

Dayton & Knight Ltd. designed and administered a contract for the construction of a 20 million litre water reservoir. 

Construction occurred in two phases: 

a) Removal of existing lining and construction of new lining, columns and walls. 

b) Roof construction.

Between the two phases, the reservoir was used by the City to provide water for the summer peak draws.  Excavation costs were minimized by constructing the walls to approximately follow the contours of the original reservoir basin.  The reservoir has a central wall which will allow cleaning of one half with the other half in service.

Promontory Zone 3 Reservoir Design Build Project, City of Chilliwack, BC

The project consisted of a supply main and storm sewer and two 2.7 ML (0.6 MG) reinforced concrete reservoirs on a steep site.  The tight design and construction schedule requirements were met and the unique design was less than the next bid received by the City.

Establishment of High Zone Pressure Zone, District of 100 Mile House, BC

A second and higher distribution pressure zone was established by the District to complement the lower pressure zone.  The work included the construction of a 450 cubic metre water storage reservoir (pictured), a booster pumping station, a pressure reducing valve station, and 1,300 m of 200 mm diameter watermain and appurtenances between the booster pumping station and the reservoir. 

The partially buried reservoir is 12 m in diameter by 3.8 m deep, and is constructed of reinforced cast-in-place concrete. The booster pumping station has two forty horsepower split case pumps and surge control equipment to supply 1.80 cubic metres per second.  Provision is made for the future addition of a third pump and an increase in the pump impeller diameters to bring the pumping capacity to 3.10 cubic metres per second.

Duncan Avenue Reservoir Expansion, City of Penticton, BC

Dayton & Knight designed the upgrading and expansion to the existing Duncan Avenue reservoir in the City of Penticton.  The old reservoir was constructed circa 1911/1912 with a capacity of approximately 3,200 cubic metres (0.7 mg).  The reservoir was open to atmosphere and had a water depth of 3.5 m. By the early 1980's the reservoir was surrounded by residential development and was falling short of meeting the City's water distribution balancing needs. 

The expansion included the addition of perimeter walls 2 m in height, resurfacing the entire concrete liner with new concrete, constructing a column supported roof and installing miscellaneous mechanical piping.  The work increased the reservoir capacity to 5,500 cubic metres (1.2 mg).  Construction required 850 cubic metres of reinforced concrete.

Eagle Lake Water Storage Reservoir, District of West Vancouver, BC

 

The Eagle Lake water storage reservoir serves the west end of West Vancouver.  

The two dams in the lake were raised 4.0 to 5.0 metres and a new concrete spillway and outlet works were constructed. 

Raising the dams increased the usable storage in the lake to 280 million gallons and increased the dam heights to approximately 10 metres.  Dayton & Knight Ltd. designed and supervised construction of the modifications.
