The Sammamish Plateau Water and Sewer District has budgeted to raise its water and sewer rates in 2016.

The district’s board of commissioners will hold a public hearing on the rates Dec. 14, immediately prior to a vote on their adoption.

According to an announcement made Friday, water rates are proposed to be raised 4.8 percent overall — the combined result of a 5.5 percent increase to customers’ base water charge and a 4 percent increased cost for water used. The district estimated that would raise the median single family’s monthly bill by $1.66-to-$1.98.

The increases follow a red-letter year for water use. Water revenue is expected to be more than $1 million above the nearly $12 million anticipated at the beginning of 2015, according to a presentation given in early November. Moreover, staff surmised that more water may have been consumed in 2015 than any other year in the district’s history.

The additional revenue for 2016 would be set to fund a major water meter replacement project, as well as improvements to water facilities to improve their stability in earthquake activity. The district his eyeing $11.2 million in water capital projects in the coming year.

Meanwhile, sewer revenue is set to increase 3 percent, which could translate to single-family customers paying anywhere from $0.97 to $33.16 more per month.

The Dec. 14 public hearing will be held at 6 p.m. in the district office at 1510 228th Ave. S.E. in Sammamish.
