Refining solutions for water quality and quantity goals
Successfully collaborating with communities on your most important infrastructure projects.
Since its formation in 1966, GPI has been at the front lines helping communities design, build and manage water, wastewater, and stormwater infrastructure. Our team is driven by the belief that water and sanitation are human rights for everyone. We help communities provide essential water and wastewater services affordably and sustainably to all residents.
Our expertise in solving water challenges was expanded with the acquisition of Hill Engineering in 2016. GPI engineers work with communities to ensure that infrastructure investment is directed strategically. Our team brings more cost-effective solutions and helps our communities thrive and achieve equitable distribution of safe, clean drinking water and efficient, affordable sewage collection.
