Two New Senior Professionals Join VEI and Vertex!

Vertex continues to expand our service offerings and to keep up with the ever-increasing demands of clients and projects we need to keep searching out and hiring qualified, new staff. This month sees two new senior professionals join the Vertex / VEI team!


Josh Douma, B.Eng., P.Eng.

Vertex is very excited to announce that Josh Douma has joined our team to lead our growing Construction Dewatering division (operating as VEI Dewatering) and will be working together with Mark Kassel and Chris Lesperance.

Josh has over 25 years of experience in the design, installation and management of construction dewatering and temporary groundwater control and treatment systems throughout Ontario and occasionally across Canada. He has completed hundreds of projects servicing heavy civil and infrastructure, commercial, industrial and residential developments in urban and remote settings. Josh obtained his Bachelors’ degree in Engineering (Water Resources) from the University of Guelph and spent a short time in the geotechnical engineering field before beginning his career in temporary groundwater control works. As a licensed Professional Engineer in the province of Ontario, Josh understands the value of practical field experience and intuition when dealing with more complex hydrogeological conditions that might be encountered during construction works, and the applicability of different pumping and system technologies in the construction dewatering industry.

“I am looking forward to participating in the development of a strong and knowledgeable construction dewatering division at VEI. It is well positioned for success as part of a complementary and multi-disciplinary team, surrounded by experienced and supportive colleagues. The willingness of VEI to invest in staff, equipment and resources and the continued collaboration with industry partners makes this a very exciting time.”

Josh can be reached at and (226) 989-6925.

Welcome to the team, Josh!
