Outside the District's sewer areas, a home in Lake Country runs on a septic system, and some acreage draws its water from a well. These are the records to ask for and the rules that apply.
In short
- Outside the District's sewer service areas a home has its own septic system, which Interior Health regulates.
- Interior Health searches a septic system's records for a $50 fee.
- A household well needs no licence, but one drilled or altered after 29 February 2016 must be registered.
- Test well water for bacteria at least once a year.

Which parts of Lake Country have municipal sewer?
The District runs a central wastewater treatment plant and three satellite systems: one in Oyama and two in the Carr's Landing area.
A property outside those service areas has its own septic system. The District neither regulates nor maintains private septic systems; Interior Health does.
A listing's Sewer line here says which it is when the feed supplies it.1
How do I get the records of a septic system before I buy?
Send Interior Health a Sewerage File Information Request; there is a $50 search fee.
A system built or changed since 2005 should have two filings: a Record of Sewerage System and a Letter of Certification from the person who installed it.
The installer also gives the owner an as-constructed drawing and a maintenance plan. Ask the seller for both.2
Who can inspect, repair or replace a septic system in BC?
Only an Authorized Person: a Registered Onsite Wastewater Practitioner or a professional engineer.
That is who a buyer hires for a pre-purchase inspection, and who files the paperwork on a new or repaired system.2
Does a well need a licence?
Not for household use. Groundwater for a private home, its garden of up to 1,000 square metres and its pets or household animals is domestic use and needs no licence.
A well drilled, altered or decommissioned after 29 February 2016 must be registered in the province's well database, and the province asks every domestic well owner to register.
Water for irrigation, a business or a farm operation is not domestic use and needs a licence.3
How often should well water be tested?
For bacteria, at least once a year, and at once if the water changes in clarity, colour or taste.
For chemistry, when the well is finished and then on a regular schedule.
The owner is responsible for the water being safe to drink. Interior Health accepts samples through its water quality program.4
