Eagle Lake, a drinking water source owned and operated by the District
of West Vancouver, supplies about 30% of the District's drinking water
requirements.
The District plans to boost this to 50%.
Water from the lake is piped approximately 1 km to a service reservoir
located about 150 m vertically below it.
In 2003, a Pelton wheel turbine was installed at the reservoir and is
now capable of producing approximately 1.1 gigawatt-hours of electricity
per year.
This power, representing about 20% of the power consumed by the
District's own operations, is sold to BC Hydro.
As a result, energy, formerly lost at a pressure reducing station, is
harnessed, transformed, and put to beneficial use.
The project is believed to be the first micro-generation power plant
installed in a drinking water system by a Canadian municipality.
Dayton & Knight Ltd. was associated with the project
from the outset.
They developed the original concept, reviewed all
engineering documents and provided project management services. |

Work commenced following the signing of an agreement between the
District of West Vancouver and Pacific Cascade Hydro Inc., who were responsible
for construction and installation. Dylan Roberts Construction was the
contractor.
Dayton and Knight Ltd. was closely involved during start-up and
troubleshooting of the equipment and its control system.
This scheme, which could probably be replicated at many locations in B.C., has
clearly demonstrated that, under the right conditions, power generation within a
drinking water distribution system is not only feasible, but also
environmentally and economically sound.
