In developing the Little Creek Casino and Resort in Kamilche Valley, WA, the Squaxin Island Tribe initiated a multifaceted
water reclamation and reuse system. As part of the scope, an irrigation reservoir, with a capacity of 3.25 million gallons, was constructed to store the Class A reuse water. The reservoir not only serves the resort, it is a harvest point for rainwater coming from an area of about 1,000 acres.
The tribe needed the reservoir completed in-line with the wastewater reclamation plant in order to service the resorts facilities. So, installation took place during cold, wet weather. The construction team specified Firestone fPP-R Geomembrane,
a reinforced polypropylene membrane because the heatwelded seams were ideal for the difficult weather conditions. Additional determining factors were the puncture resistance and minimal elongation properties of the membrane.
