More than a decade and a half after construction began on the 7,000-resident Issaquah Highlands community, renewed conflict has erupted over how to handle the stormwater it generates.
The state Department of Ecology is on track to allow treatment of the water by filtering it through sand and gravel above an aquifer that provides drinking water to tens of thousands of area residents.
Officials at Ecology and the city of Issaquah say the plan — envisioned for years — is a safe, proven way of replenishing the aquifer and removing potentially harmful bacteria.
But the area’s largest water provider, the Sammamish Plateau Water and Sewer District, wants contaminants including fecal coliform removed before the water goes into the ground.
