Why SPI?

Since 1980, SPI has become an internationally recognized consulting engineering firm focused on the application of membrane technology and other advanced processes for water and wastewater treatment.

Our engineering services span the entire lifecycle of a project, including planning, pilot testing, design, construction and full-scale operations support. SPI has developed an intimate knowledge of membrane processes through the coupling of our operations support and design services. The result is a feedback loop that continuously improves both our system designs as well as support offered to our clients operating membrane facilities.
