$1 million capital saving by appropriate process selections.

Won CEBC Award of Merit for ATAD design.

In a competition in 1986, the Resort Municipality of Whistler chose Dayton & Knight Ltd. to design a new sewage treatment plant that provided the municipality with a $1 million saving in construction through the selection of a trickling filter – solids contact process over the RBC process proposed by others.

The addition of an ATAD facility following 1990 included belt filter press dewatering.

In 1996, construction initiated a Stage III expansion to capacity for 52,500 people and included a bioscrubber, odour control tower with an expanded system capacity to provide future addition of biological nutrient removal.

The high quality of effluent meets stringent phosphorus limits, and the pasteurized biosolids are in continuous demand by public, business ventures and the forestry service.

The Liquid Waste Management Plan requires the municipality to evaluate optional disposal solutions including infiltration and spray irrigation.
