Interior Health regulates the potable water supply in BC under authority of the Drinking Water Protection Act. The potable water quality parameters described in the Guidelines for Canadian Drinking Water Quality are used to set the water quality standard.

The minimum criteria set by Interior Health are:

  • 4 log inactivation of viruses
  • 3 log removal or inactivation of Giardia Lamblia and Cryptosporidium
  • 2 refers to two treatment processes for all surface drinking water systems
  • 1 for less than 1 NTU of turbidity with a target of 0.1 NTU
  •  0 total and fecal coliforms and E. Coli

Interior Health provides written Conditions on Permit that require water system operators to achieve a number of outcomes including trained operators, source protection plans and water treatment. By implementing a multiple barrier approach to potable water supply, the public health risk is reduced. SEKID meets these criteria, including employment of certified operators, a cross connection control program and a comprehensive city-wide groundwater source protection program.

The existing groundwater supply has been approved for potable water consumption since 1980, without treatment. The WQIP will provide primary treatment, adding another layer to the multi-barrier approach to public health protection. SEKID's existing groundwater supply satisfies the total volume of the district's current demand and only a slight increase of additional capacity will be required by new licensing in future.

SEKID complies with all conditions related to public health except Condition 7.  The requirements of condition 7 are as follows:

Provide long-term plans for source, treatment and distribution system improvements taking into account the goal of the Drinking Water Treatment Objectives (Microbiological) for Surface and Ground Water Supplies in BC.

We have received written confirmation from Interior Health that the groundwater supply proposed for the WQIP meets with the potable water requirements of Condition 7, with the exception of timing, and therefore compliance is a work "In Progress." Without grant funding the program will not service the entire district until 2035, when the last of the rural domestic distribution system will be complete. IH would prefer the completion date to be considerably sooner, which would be possible with grant funding. When the WQIP is completed, SEKID will be in full compliance with public health standards:
