Greater Winnipeg Water District Aqueduct

563:. Over its length the aqueduct crosses eight rivers. The conduit was built using the "cut and cover" method with an unreinforced concrete arch resting on a cast in place base invert. Sections at road and rail crossings had reinforcing steel. Siphon crossings of rivers were made as reinforced round concrete tubes. The interior dimensions of the aqueduct were selected so that no internal pressure was developed by the water flow; nineteen different interior sections were required. For inspection and maintenance, manholes were provided at approximately 1 mile intervals, which allow insertion of a small boat for inspections. Vent pipes in the manholes allowed controlled entry of air. 743: 250: 503:
flow to the City of Winnipeg from 30 to 42 million gallons per day. The station was equipped with three 20 million gallons per day pumping units with electrically controlled switchgear and electrically operated discharge valves. This was the first major addition to the District's aqueduct since the original works were completed in 1919.

provided that interest and sinking fund charges should be levied on land only. The GWWD Act was amended in 1927 to allow a maximum price of five cents per thousand gallons to be charged, which became effective on 1 January 1938.

Initially the aqueduct terminated at a reservoir built on McPhillips Street, which had been the center of the city's original water system. The design of the project included provisions for an additional reservoir approximately 13-mile (21 km) east of the McPhillips reservoir. This would allow

As a result of steadily increasing demand for water, construction of a booster pumping station adjacent to the Greater Winnipeg Water District's surge tank in St. Boniface was completed in 1950. This station allowed the District to fully develop the capacity of the existing works and to increase the

The project was carried out as outlined in the engineering report with the addition of a 250 million gallon reservoir at Deacon (about eight miles east of St. Boniface), a second 5-foot 6-inch pressure pipe from Deacon to the Red River, and a booster pumping station on the east bank of the Red River

On 7 April 1913, the Winnipeg City Council appointed a Board of Consulting Engineers to estimate the cost and general plan of the project to supply the Greater Winnipeg Water District with water from Shoal Lake. This report was submitted on 20 August 1913 and contained the following recommendations:

The engineering report was adopted by the Administration Board of the Greater Winnipeg Water District on 6 September 1913. A by-law was passed to raise the sum of $ 13,500,000 for the project by the issue and sale of debentures. The plan was put to Winnipeg voters on 1 October 1913 and was approved

Since the Falcon River entering Shoal Lake drains a considerable area of muskeg, a dike was built in the lake to prevent brown, organics-laden water from being drawn into the aqueduct. The intake structure included dual intake chambers to allow for maintenance of one while the other was in use.

Surveying along the route of the aqueduct began in 1913 and construction commenced on 1 March 1914. The first work to be undertaken was the building of a 110-mile (180 km) railway, including siding and spurs, a telephone line, clearing and fencing of the right-of-way, and completion of the

Between 1900 and 1908, a group of seven wells were dug. These averaged about 5.5 metres (18 ft) in diameter and varied in depth from 14 to 31 metres (46 to 102 ft). In some years, their yield was not consistent and it was evident that a more adequate supply was needed for the rapidly

The first water supply system in Winnipeg was installed and operated by the private Winnipeg Water Works Company, which obtained its charter on 30 December 1880. The charter was for a 20-year period and the works were put into operation in 1882. The source of supply was the

Structural design was complicated by the widely varying ground conditions, ranging from rock to soft peat soil. In some places, gravel fill was brought in to replace unsuitable material excavated. The depth of backfill was intended to protect the aqueduct from freezing.

In 1954, the District completed a direct 41-centimetre (16 in) diameter pipe connection between the aqueduct and the Municipality of St. Vital, the cost being borne between the District and St. Vital. A pumping station was paid for and operated by St. Vital.
570:
To allow surface water to drain freely across the path of the aqueduct, inverted siphons were installed at fifty-six locations. Freezing was prevented by ensuring the outlet level was always below water level, preventing cold air from entering the siphon.
