Study proposed to investigate impact of septic fields in Okanagan Lake is the headline in the Kelowna Capital News on February 24. This was Item 6.2  at the Feb 24 RDCO Board Meeting you can listen to the Audio of the Staff Presentation and Board discussion on the Grant application.

At the request of RDCO, Larratt Aquatic is pleased to present this proposal for a study designed to determine the impact of septic fields on the foreshore of Okanagan Lake in the Killiney Beach and Westshore Estates area.
The study will include periphyton analysis and water chemistry with sampling occurring from June to October 2020. At the completion of the study period, LAC will prepare a final report that will be supplied in draft to RDCO in December 2020.
The project is designed to be cost scalable with a summer only and a summer + fall option for more rigorous statistical results. The expected cost of the full project is $16,020 for the field work and reporting phase with lab costs of $4,109 while the summer-only option has a price estimate of $11,650 for field work and reporting with lab costs of $2,054.52.

This Study RDCO – Killiney Periphyton Proposal Feb 19 will occur to collect data in advance of proposed upgrades to the water intakes from Okanagan Lake for both the Westshore and Killiney water systems.
