A leading local expert on water resources has waded into the recently announced water plan for the City of Kelowna, and while he says the plan appears to have identified a potentially cost-effective way to provide an integrated water distribution system for the city, a number of issues still need to be addressed to make the plan.
John Jammaat, associate professor of economics and the RIC chair of water resources and ecosystem sustainability economics at UBC Okanagan’s I.K. Barber School of Arts and Sciences, says the capacity of Mission Creek to provide the required amount of water to satisfy all domestic needs—as called for in the plan—must be addressed in light of climate change, a way has to be found to bring in the three holdout irrigation districts to make the city-wide aspect of the plan work and a practical way of ensuring agricultural users manage their water properly must be found.
“Hopefully, we (are) not being rushed to the chapel for a shotgun wedding before really figuring out the practicalities of living together,” writes Jammaat in piece published on the UBC Okanagan Watershed blog.
Earlier this week, the new plan was unveiled, but without the participation or support of three of the four water provider in the city. Kelowna is currently served by five main water providers—the city, the South-East Kelowna Irrigation District, Rutland Water Works, the Black Mountain Irrigation District and the Glenmore-Ellison Improvement District.
Consultant Don Stafford told city council during his presentation of the plan that it is a technical document and does not address the controversial issue of governance.
At this point, only the city and South East Kelowna Irrigation District SEKID are part of the plan.
After announcing in November that they had agreed to be participate in the value planning study that lead to the plan, the three holdout—Rutland Water Works, BMID and GEID walked away rather than agree to become part of the city’s water system should the city successfully apply for provincial infrastructure grants on their behalf in the future. The requirement is a condition of province approving grants for irrigation districts, according to the city.
The province also supports the new Kelowna water plan.
Here is Jammaat’s blog posting:
In November 2016 it was announced that the five main water providers in Kelowna had agreed on a statement of principles and terms of reference for a value planning process that will allow for an independent third-party to review all relevant documents and information that would inform the development of a new, integrated water system for the region over time (news.gov.bc.ca).
A consultant was hired, stakeholders and experts recruited, and a value planning workshop was held January 9-13. The value planning exercise started from the 2012 Kelowna Joint Water Committee integration plan, and looked for ways that water services could be enhanced and/or costs reduced. The report on the value planning exercise was released on the 27th of February.
The analysis recognizes one of the things that I pointed out in an earlier posting, that the cost of delivering water around Kelowna might offset the advantages of centralized treatment. They identified a solution that takes advantage of the scale economies of centralized treatment, and the opportunities to avoid some treatment costs if high quality source water is used, while using gravity to move water some of the time. That solution is to use Mission Creek as much as possible. Mission Creek water is, for much of the year, of sufficient quality to require minimal treatment (i.e. no costly filtration), and when Mission Creek water is not of that quality, the plan sees the lake intakes being used. Therefore, by integrating the system and taking advantage of these two sources – Mission Creek and Okanagan Lake – the cost of pumping water can be kept down, and the cost of treatment kept down as well.
The first phase of the project will be to build infrastructure to bring Mission Creek water to the residential areas presently supplied by South East Kelowna Irrigation District (SEKID), avoiding installing the wells that were originally seen as a solution to water quality issues faced by SEKID. It is acknowledge that this will be more costly than the wells, but in the long run as Mission Creek becomes an important source for the entire city, would be an appropriate investment.
Good job to the value planning consultant for identifying this option. However, on my first reading of the report, I am left with some questions. Here are a few of them and my thoughts.
1) The Missing Water Providers
The value planning exercise includes only SEKID and the city. The remaining three opted out, even after agreeing to the original guiding principles mentioned in the press release. Something happened to the goodwill that was in place in 2012, when all were working together. How will the lack of full involvement by all the water providers impact on the ability to implement the plan. Part of the proposed plan sees using Black Mountain Irrigation District (BMID) infrastructure to manage withdrawals from Mission Creek (Alternative 4, page 3-27). How can this be implemented if BMID is not involved? Will additional infrastructure need to be built to operate things in the mean time until BMID is brought on side? How much will that cost? Or, without BMID, might it be cheaper to avoid using Mission Creek for now and install the wells originally envisioned to deal with water issues in SEKID?
2) Mission Creek
Mission Creek is a ‘Fully Recorded’ water source, which means that the province will not issue new licences on the creek. This is because the reliable supply on the creek is not seen as sufficient to supply extra licences. The city has three relatively small irrigation licences on the creek. BMID has by far the largest licence volume on the creek, and they are not part of the plan. The city would need to have new waterworks licences on Mission Creek to be able to withdraw water from the creek, and as presently classified, the province will not issue new licences. The value planning exercise did not address these issues. It was not part of the mandate. From the report:
The VP Study was to specifically focus on the technical solution without regard to
system Governance. Further, the technical solutions were not limited based on any
ownership or rights to existing systems (page 1-3).
This means that there are important legal and governance issues that need to be resolved before this plan can be implemented. Or, there may be legal and governance issues that mean this plan cannot be implemented.
3) Climate Change
Climate change is widely recognized as the single greatest unknown for future water supply planning. Potential impacts include, increased growing seasons in the shoulder months, precipitation falling more as rain rather than snow in the uplands, increased irrigation requirements (both domestic and agriculture), increase in extreme events (both drought and flooding), and possible reductions in mean streamflow (page 3-41).
The projections for the Okanagan are for an earlier freshet, a longer low flow period, and a lengthened season when plants need water. There are kokanee that spawn in Mission Creek during that low flow period, and they need water. It would seem that before moving forward with construction that anticipates relying on Mission Creek, it would be important to develop some forecasts of how much water Mission Creek can reliably supply into the future. There has been some work done related to this issue by people at the Pacific Agricultural Research Center and by the Okanagan Basin Water Board. Such work was not mentioned in the report. What information is available for Mission Creek needs to be consulted, and the risk that Mission Creek cannot be relied upon needs to be fully quantified. If the risk is large, then the projected cost savings are a gamble, rather than a sure thing. Since the up front costs of starting down this path are high, if the dice do not fall in our favor, we will have spent money that we cannot recover.
4) Agriculture
Protecting the interests of agriculture was recognized as an important part of the value planning exercise, and the suggestion of separating agricultural supply from domestic supply makes sense. How will this be governed? The present governance has some challenges, and there is potential to improve things. Based on information in the 2012 integration plan, the three irrigation districts presently supply more water to domestic customers than their licence volume permits. They have agricultural and domestic licences, and while their supplied water is below the sum total of their licence volume, the amount going to domestic uses exceeds that licenced for domestic purposes. This presents a challenge for agricultural water users, as water is ‘seeping’ out of agriculture into domestic water uses. If agricultural water licences are vested in a body that is independent of the city, managing a separate delivery system and/or contracting with/to the city for the types of resilience issues mentioned in the report, then the result may be good for agriculture. However, if this amounts to a capture of almost all the water rights in the Kelowna area by the city, then agricultural users are likely to be a lower priority to the city. Agriculture is an important use of the land and a valuable contributor to the quality of life here in Kelowna. However, it is a relatively small economic contributor, relative to those activities related to the continued growth of the city (construction, real estate, etc., see this post). Integrating the water providers in the city makes it easier for development, as all major infrastructure decisions related to development are made by one local government. This is a benefit for some that is independent of doing anything to address water quality issues. However, that comes at the cost of removing a structure which gives agriculture a larger voice relative to the other interests trying to get the ear of local government.
5) Governance
A theme that runs through the points I raise above is governance. Negotiations between nations, between business partners, and between domestic partners take time, and are successful when all parties feel that they are better off by being part of the deal than not. Deals that are rushed often do not work. This process was entered into and the timeline set by the opportunity to access infrastructure money available from the federal and pr
