Site work for a water / sewer project in Lethbridge, Alberta. Completed plans call for site work for a water / sewer project.

The proposed project consists of a potable water transmission main to service large agri-food users within Lethbridge County between the Town of Coaldale (Town) and the Hamlet of Chin (Chin). The transmission main will provide water to the proposed service area by connecting to the Lethbridge Regional Water Services Commission's (LRWSC) existing infrastructure on the west side of the Town. The transmission main will also provide potable water to the Town's proposed pump station and reservoir. The alignment of the transmission main will be located within Range Road 203, Township Road 94, and private lands adjacent to the Canadian Pacific Rail to the east of Township Road 192; an overview of the alignment is shown on Figure 1. Due to the presence of shallow utilities within the road allowances, the transmission main will be located within the road structure, below frost depths, to mitigate conflicts. This will require restoration of the gravel road and ditches at entrance/exit pit and appurtenance locations. Major work items for this project will include, but not be limited to, the following: a) Connection to the LRWSC's existing 500mm PVC transmission main, b) Supply and installation of 18km of 450mm HDPE pipe by horizontal direction drill (HDD), c) Supply and installation of associated transmission main appurtenances (air release valves, isolation valves, flushing hydrants, and drain assemblies), d) Eight (8) County Road Crossings, e) Highway 845 Crossing, f) Two (2) St. Mary River Irrigation District Canal Crossings, g) St. Mary River Irrigation District Pipeline Crossings, h) Canadian Pacific Railway Crossing, i) High Pressure Gas/Oil Pipeline Crossings, j) Overhead power and shallow utility coordination/crossings, k) Gravel Road, Ditch, Cultivated Field, and/or Pasture Restoration at open excavations/drill pits, l) Construction coordination with the Town's pump station and reservoir contractor, m) Pressure Testing, Flushing, and Disinfection of the transmission main.
