Tonka Equipment Company
The Spanaway Water District, located near Tacoma, Washington, needed a solution to manganese problems at a 900 GPM well, and a filter design that would fit into their new treatment building layout. They also wanted to minimize the backwash waste set up for discharge into a small infiltration basin. The District had previous failures of off-the-shelf standardized skidmounted vertical pressure filter systems, so they contacted Tonka, looking for a fresh, more robust approach.
