On Site Construction

Our on site construction team will ensure design and operational specifications are met, from start to finish.

Some treatment systems are simply too large to pre-construct and transport. In these large-scale projects Seneca also has the capabilities to construct the entire treatment system onsite including installation of underground piping, extractions wells, burying power and communication lines. Our team of welders, plumbers, programmers, electricians and project managers will ensure the project is safety constructed to specifications and operates as designed.
