Intro to the BMID

The Black Mountain Irrigation District (BMID) is an improvement district operating within the Central Okanagan Regional District. A large portion of our service area falls within the City of Kelowna boundaries. The Scotty Creek subdivision area that we service located north and east of the airport lies within the Regional District of Central Okanagan. Our primary water sources are the Mission Creek and Scotty Creek watersheds.

BMID is the largest improvement district in the Province. As of December 2021 we service a population of approximately 26,000. We serve approximately 6,000 Single Family Dwellings. We have nearly 10,000 total connections comprised of residential, agricultural, commercial, industrial and institutional properties.

Our agricultural connections irrigate lands in the the Belgo, McKenzie and Ellison areas of Kelowna.  We have three grades of agricutural land (residential lots under .5 acres are not included in this listing):

  • 4,947 acres of Grade A land. Grade A land has rights to water and uses it;
  • 1,055 acres of Grade C land. Grade C land has rights to water but is presently not using water;
  • 2,454 acres of Grade D land. Grade D land does not have rights to water;
  • If water availability is determined, a regrade charge can be paid to purchase watering rights.
With the combined water demands, our winter demands of 2,000,000 US gallons increases to 40,000,000 US gallons during the hottest days of summer. Our water is collected in high elevation reservoirs during the winter and spring runoff and is released to Mission Creek during the hotter summer months and captured at our intake.

Our upper level water storage reservoirs include Belgo Reservoir, James Lake, Graystoke Lake and Fishhawk Reservoir. Mission Creek is the largest tributary to Okanagan Lake and is a very strong source of water for the District. The annual flow past our intake gates is 135,000 ML.

Intro 2Conveyance Conduit
After we capture the water at Mission Creek, the water is treated, disinfected, and conveyed by large conduits to town. 

The conveyance conduit carries the water at a very flat grade along the Mission Creek canyon to a tunnel located on the shoulder of Black Knight Mountain. The 900 metre long tunnel carries the water into town maintaining the high elevation resulting in minimal pumping and very efficient distribution throughout our water system.
The tunnel emerges at our Surge Tower located above the Gallaghers Road subdivision. From here the water enters distribution mains and is carried into the agricultural and more populated areas of Rutland and north Rutland.

The entire water supply system consists of:

  • 600 square kilometers of watershed in Mission Creek and Scotty Creek basins;
  • 4 large storage reservoirs and dams in the watershed;
  • Two intakes on major creeks;
  • 105 ML/day water treatment plant;
  • Two large open holding reservoirs 200,000 m3 in size for balancing daily water demands;
  • A new Ultra Violet (UV) Treatment Facility; 
  • 3 chlorination stations;
  • 3 groundwater wells;
  • 13 major pressure zones;
  • 27 pressure reducing stations;
  • 6 water pumping (booster) stations;
  • 4 local storage reservoirs; and
  • 175 kilometers of water distribution main.

These facilities and our offices are maintained and operated by our 20 staff members.

Improvement District Responsibilities

As an improvement district, BMID is an autonomous local government body responsible for providing water services for the benefits of our ratepayers. Improvement Districts were brought into existence by the Province through a Cabinet Order approved by the Lieutenant Governor in Council. The Lieutenant Governor approved the Letters Patent which includes the name of the District, its boundary, and the services it provides. BMID’s Letters Patent was signed on November 20, 1920.

The affairs of BMID are directed by five elected Trustees with one Trustee elected as Chairman by the group. Each trustee is elected for a three-year term by the eligible landowners of the district. The powers that are exercised by the Trustees include the ability to enact and enforce the district bylaws. These bylaws provide BMID with the ability to assess and collect taxes, to charge tolls for water use, to acquire, hold and dispose of lands, to borrow money, and to expropriate lands required to carry out its objectives. All bylaws must be approved by the Trustees, and subsequently filed or registered by the Inspector of Municipalities.

Water Quality Advisory - starting September 27, 2022

Please be advised that the Black Mountain Irrigation District has issued a precautionary Water Quality Advisory for the entire BMID service area, due to a change in water treatment. 

This Advisory has been called due to preventative maintenance work being performed on BMID infrastructure.  In order to perform the work, water will have to bypass the Ultra-Violet Disinfection Facility, which provides treatment for protozoa such as Cryptosporidium and Giardia.  While water may not be treated with UV, the water will still be treated with the clarification process and disinfected with chlorine. 

The Advisory will begin on Tuesday, September 27 when the work begins. The UV facility will be operational by end of day on September 28, 2022.  However, the Advisory must continue until approximately October 5, 2022 when fully treated water (i.e. treated with both chlorination and ultra-violet disinfection) will have dispersed throughout the entire distribution system. BMID will rescind this Advisory once testing results have been reviewed by Interior Health.

Customers affected by the precautionary Water Quality Advisory (such as the elderly, those with young children or infants, those with weakened immune systems or anyone seeking a higher level of protection) may wish to boil their water for at least one minute when using it for purposes such as:

  • Drinking
  • Brushing Teeth
  • Washing fruits & vegetables to be eaten raw
  • Preparing any food
  • Mixing baby formula
  • Making beverages or ice

BMID requests that all customers reduce their water use, especially those using outdoor / agricultural irrigation on September 27 & 28th.  BMID apologizes for any inconvenience this Advisory may cause and appreciates your patience during this time.

If you have any questions, contact Black Mountain Irrigation District office at (250) 765-5169.
