Eastern Irrigation District
The following is a complete list of all projects included in the Eastern Irrigation District (EID) under the modernization program. There are seven pipeline projects and one reservoir expansion project.
This rehabilitation project is located approximately seven kilometres north of Brooks. The proposed rehabilitation is to install a closed gravity pipeline system that starts at Rock Lake Reservoir and continues east across the Duchess highway. At Rock Lake Reservoir, there will be a shared stilling pond and gabion wall with the 01-C Springhill system. The system will tie into a few existing pipelines, one being the Long Pump. The pumps on this system will still be necessary for priming pressure to the landowners. The start of the pipeline is 60” pipe, and the new system will supply 6224 acres, 97 per cent of which are sprinkler and will be 10 kilometres in length. The major benefit of the project is the maintenance of spill water within Rock Lake Reservoir.
The estimated cost of the project is $11,385,000.
The 01C Springhill project will replace the 30-year-old Springhill pump station with a new pump station located at Rock Lake Reservoir, providing the opportunity to capture all spill water. This new pump station will supply 1757 acres with full operating pressure, negating the need for irrigators to operate their own pumping systems. The starting pipe size will be 30” and the pipeline will be six kilometres long.
The estimated cost of the project is $5,112,000.
9H West Bantry
The 9H West Bantry pipeline project will finish converting the 9H West Bantry system into a closed pipeline. The project is located approximately 2.4 kilometres north of the intersection of HWYs 875 and 535. The new pipeline will be 1.8 kilometres long and currently serves 541 acres. Fifty-three acres will be added to the pipeline to eliminate a delivery in the H West Bantry canal, which currently accepts spill water from flood water in NE8 17-13W4M. As such, only the first half mile of the ditch can be pushed in, with the remainder maintained as drainage works.
The estimated cost of the project is $957,000.
10H West Bantry
The 10H West Bantry pipeline project will convert the 10H West Bantry system into a closed pipeline. The primary benefit of this project will be a reduction in spill. The project is located at the intersection of HWYs 875 and 535. The new pipeline will be 5.5 kilometres long and serve 1117 acres. The pipeline will require two road bores under paved highways and include a screen cleaner at the inlet structure.
The estimated cost of the project is $2,892,000.
16H West Bantry
The 16H West Bantry pipeline project will convert the 16H West Bantry system into a closed pipeline. The primary benefit of this project will be a reduction in spill. The project is located 3.2 kilometres south of the intersection of HWY’s 875 and 535. The new pipeline will be 3.3 kilometres long and will serve 1112 acres. The new pipeline will require one bore under highway 875 and will include a screen cleaner on the inlet structure.
The estimated cost of the project is $2,266,000.
08B Springhill Extension
08B Springhill pipeline extension will serve 429 acres through a pipeline length of three kilometres. This closed gravity pipeline will meet the delivery points of three existing pivots that currently pump out of a drain that sees a reduced amount of water every year. This new pipeline will move them from that drain and onto a closed gravity system.
The estimated cost of the project is $1,250,000.
The 12 Springhill pipeline involves replacing the remainder of the open channel ditch with a closed gravity pipeline completing the system. This pipeline will serve 5118 acres with a starting pipe size of 54”. The start of the pipeline will be relocated upstream of an existing reservoir, providing the opportunity to capture spill water.
The estimated cost of the project is $910,000.
The proposed Snake Lake Reservoir expansion plan will increase the reservoir live storage by approximately 53000 acre-feet to 67000 acre-feet*.
Currently, 140000 irrigated acres are either unsupported by a reservoir or receive limited reservoir support. Approximately 50000 of these acres are downstream of the Snake Lake Reservoir. The Snake Lake Reservoir expansion will reduce the unsupported acres in the District by 35 per cent.
The remaining 90000 acres will continue to be unsupported by a reservoir, but will see increased indirect support due to the increase of acres being supported from the Snake Lake Reservoir Expansion.
Environmental and engineering investigations are underway, meetings with affected landowners are ongoing, and discussions with government officials on the regulatory approval process are occurring.
