The PBI team brings a wealth of planning and design expertise and experience to its clients. PBI employees are experienced in all facets of planning and design for water and wastewater treatment plants, wastewater reuse facilities, and raw water supply facilities. Team members have completed many new, renovation, and expansion designs of water and wastewater treatment plants, some of which are listed below in Selected Projects.

Identifying and maintaining adequate and sustainable water supplies is perhaps the largest challenge faced by mankind in the 21st century. Overtaxed systems will face the added obstacle of global climate change. PBI staff have led major water supply and integrated resources planning efforts for clients in California, and are currently developing methodologies to address climate change in ongoing studies.
