Shamrock Civil worked with the client and SPEL to improve the design proposed and change it for the SPEL systems to provide a cost saving to the client as well as a better efficiency. The previous units were too large for the area. The project was environmentally sensitive and PFAS material was treated and dealt with locally to ensure the most efficient and least risk involved with how it was handled. This included burying it onsite and capping it to avoid exposure.
