The Core Area Wastewater Treatment Project will begin to gather additional information about the subsurface conditions at McLoughlin Point for the Wastewater Treatment Plant.
This geotechnical information is used to locate the top of the bedrock, understand the soils and rock that will be encountered during construction, and to design supporting foundations which will withstand the settlement and seismic forces that may be present.
As the Project has sufficient information about the subsurface conditions and suitability of McLoughlin Point to host the Wastewater Treatment Plant, the geotechnical work does not impact the plans provided in support of the development permit application but will assist in finalizing the designs. Construction of the Wastewater Treatment Plant will not commence until the Township of Esquimalt issues a development permit.
The McLoughlin Point Wastewater Treatment Plant will provide tertiary treatment to the Core Area’s wastewater. The facility consists of three major components, the treatment facility at McLoughlin Point, a forcemain under Victoria Harbour, and an outfall pipe from the facility to a discharge point off shore.
The geology at McLoughlin Point varies from exposed bedrock to natural and artificial fill. A series of boreholes will be used to determine soil characteristics at key points at McLoughlin Point, along the harbour crossing alignment, and along the outfall pipe alignment. This work builds upon previous geotechnical investigations at McLoughlin Point by locating boreholes in different locations and by conducting different laboratory tests of the core samples.
The geotechnical investigation will take place in three phases. The first phase will be the land based drilling at McLoughlin Point. This phase will begin January 10 and is expected to take approximately five days to complete. The following phase will take place along the harbour crossing of the forcemain and is scheduled to take place in the first two weeks of February. The second phase of work will take approximately 10 days to compete. The final phase will be scheduled in the spring of 2017 and will provide more information regarding the outfall pipe alignment route. This phase is expect to take 12 days to complete.
