Mr. Robinson’s over 30 years of environmental engineering experience has focused exclusively on water reclamation, wastewater engineering, and wastewater master plan projects for municipalities in California and Arizona. He has been the Principal-in-Charge or Project Manager for infrastructure projects that include feasibility/master studies and planning, preliminary and final designs, bidding, construction management, and commissioning. His project experience includes 15 new water reclamation and wastewater facilities, 4 groundwater treatment projects, 300 miles of sewer, potable water, and recycled water pipeline designs, 15 pump stations, 12 groundwater wells and 10 reservoirs and 45 master plans for water, sewer, and recycled water. During his career he has completed over 550 recycled water customer conversions (i.e., water through the meter) as well as completed an additional 2,000 recycled water customer conversion assessments. He specializes in assisting clients with identifying and assessing customers, evaluating potential non- potable reuse system components as well as managing the customer development for all customer conversions; developing recycled water conversion plans, working with customers, and developing conversion construction costs. Mr. Robinson has developed and conducted training seminars for both client staff as well as end use customers. He is particularly adept at working closely with SWRCB DDW and OCHCA for coordination of site issues and approvals and understands how to make the regulatory approval process go smoothly.
