Sharing water resources over a wide region is an idea that goes hand-in-hand with the Growth Management Act’s strategy of concentrating population in urban areas while protecting rural areas.
Of course, the first level of action is water conservation. But the ability to take water from one aquifer with an adequate water supply while protecting an overtaxed aquifer somewhere else makes a lot of sense.
That’s the idea behind building new pipelines to connect numerous water systems across a good portion of Kitsap County, including Silverdale. I described the latest steps in this plan in a story published in Monday’s Kitsap Sun.
Thirty years ago — before the Growth Management Act was passed — I recall talking to folks at the Kitsap Public Utility District, who declared that they were not in the land-use business and had no intention of getting involved in land-use battles. It was the job of the Kitsap County commissioners to decide where to put the growth, they said. The PUD staff and commissioners believed their role was to provide water for the growing population, wherever it goes. Check out this Kitsap Sun story from Feb. 25, 2001.
The state’s Municipal Water Law of 2003 clarified that the KPUD could deliver water from one place to another throughout its service area — which is all of Kitsap County. That allows water to be brought to developed areas in North Kitsap, where annual rainfall is half of what we see in the forested areas of Southwest Kitsap, where the Seabeck aquifer is located. (See annual precipitation map on this page.)
Many environmentalists have objected to certain portions of the Municipal Water Law, especially sections that included developers as municipal water suppliers — a move they say opens the door for abuse by financial interests.
One of the big concerns in water management is that pumping too much from an aquifer — especially a shallow aquifer — could disrupt the subsurface flows and springs that maintain stream levels in the summer and early fall. Adequate streamflows are needed for many species, not the least of which are salmon.
With adequate monitoring, as needed for planning, experts can track groundwater levels and streamflows to avoid such problems. Pipelines allow aquifers to be “rested” when needed. And elected PUD commissioners can be held accountable for their decisions regarding the regional management of water.
Future water supplies and the right to use the water constitute one of the most complicated issues in environmental law. A 2003 paper by the Washington Department of Ecology, called “Mitigation Measures Used in Water Rights Permitting” outlines some of the methods being used to protect natural systems and competing water rights. Mitigation for use of the Seabeck aquifer, which is an important water supply in Kitsap County, is described briefly on pages 19 and 20.
