Since its formation in 1966, GPI has prided itself with growth in municipal work that involved water distribution systems and reclaimed water projects. In 2016, we initiated an expansion of our services in water and wastewater engineering with the acquisition of Hill Engineering, Inc. As a result, we have increased our capabilities in design development and construction/rehabilitation of wastewater treatment facilities. Combining the new strength of wastewater treatment design with the traditional strength of our construction management has many people excited about our future in Water/Wastewater Management.
