Water quality and frost depths
The City of Whitehorse, as part of its Permit to Operate a Large Public Drinking Water System, collects weekly water samples for residual chlorine and temperature from 28 stations across the water distribution system, as well as samples for independent bacteriological analysis. In addition, water samples are collected two times per year at the Selkirk Pumphouse (after chlorination), for general chemistry and metals. The following table presents the latest results:

Danger of frost has passed and all frost protection devices should be turned off.
Your frost protection devices include bleeders, heat trace tapes, transformers and aqua flows. Please note, for those residences with the temperature control bleeders (TCB’s) nothing is required.
Questions relating to these devices can be directed to the City of Whitehorse, Water and Waste Services, 668-8350 from 8 a.m. to 5 p.m., Monday to Friday.

This is the interior of a newly constructed water reservoir. The coloured arrows represent the level of the reservoir if it was full of clean potable water and the amount for each of the identified uses.

This is the lift station where waste is pumped to the treatment lagoons.
