PERC Water Corporation (originally Pacific Environmental Resources Corp.) was founded in January 1998 by Johan Perslow, a licensed civil engineer and general contractor with more than 40 years of experience in the water sector. Familiar with the challenges associated with the traditional contracting method of design-bid-build (where each phase of the project exists as an independent transaction), Mr. Perslow sought to create a single-source entity that could be relied upon from the initial design phases through long-term operations. His philosophy transfers the inherent client risks of capital cost, operating costs, delivery schedule and performance directly to PERC Water. PERC Water has successfully designed, constructed and operated water recycling facilities across the United States. The company has designed more than 55 facilities – 20 of which have been designed, built and operated by PERC Water. We have commissioned and operated all of the completed facilities following construction and continue to offer support services to clients that have assumed the operations of our facilities.
