White Rock residents will soon start to see financial impact of plans to upgrade the city's water system. To the average homeowner, it's a boost of $5.77 per month, to $25.29. But if Epcor's rate apllication to the B.C. comptroller of water rights is approved, the bills will increase by about the same rate every year through 2017. That means the average homeowner will be paying more than double what they were last year by the end of the term.
