Chestermere’s sanitary system is currently operating beyond its designed capacity.

LS 13 (completed mid-2016) was designed to serve as Chestermere’s primary lift station, pumping Chestermere’s wastewater to Calgary. In addition to providing capacity required to relieve the existing system constraints, it has been designed to accommodate the growth expected over the next 25 years.

The Rainbow Road Sanitary Trunk Phase 1 project is the construction of 0.7 km of 1050 mm gravity main between Rainbow Falls Gate (connection of LS 4 FM) and LS 13. It is required to create relief at LS 10 by diverting flows from LS 4 and LS 12 (including LS 5, once diverted to LS 12) to LS 13. The necessary system relief will only be achieved once both LS 13 FM and RRST are tied into LS 13 and are operational.

Once completed, RRST will receive a total flow of 450 L/s; 92 L/s is required to relieve current system constraints with the remaining 358 L/s available to serve future development.

Project construction will commence in Fall 2017 after further design work has been completed.
