South Pender Harbour Water Treatment Plant


Sunshine Coast Regional District

Completed Date


Project Description

This project involved the design and construction of a new water treatment plant on the Sunshine Coast in British Columbia to improve water quality in the area.

Tritech’s scope of work for this project included:
  • Improvements to the existing access road from Highway 101. Approximately 1.5 km of Forestry Service Road included road widening, ditch improvements, drainage culverts and re-grading.
  • New Water Treatment Plant and Waste Pond construction included clearing and site grading. Site improvements included Backwash Settling Ponds, Reservoir Earthworks, ditching, general grading and surfacing.
  • Provision of site overhead and underground power and communications from Highway 101. Works included approximately 1.1 km of overhead lines, complete transformer banks, and installation of underground Power and Communication service lines.
  • Construction of a pre-engineered building for the water treatment plant structure was completed over a 500,000 litre concrete clear well storage reservoir. The treatment system comprised a 2.6 MLD DAF / filter / UV treatment system complete with chemical systems.
Tritech proposed process design changes to reduce the project cost by $500,000. The project became a re-design-build project, with Tritech taking responsibility for the structural design, modifications to the building layout (architectural, mechanical, and electrical) and process design changes. Tritech worked to meet all environmental regulations with the B.C. Ministry of Forests, Lands and Natural Resources. Despite a few challenges caused by the natural terrain, the project was brought in on time and on budget.
