Filter Refurbishment

AMT Systems carries out refurbishment of both the internal and external underdrain and pipework systems of filters.

This work includes design and installation of air headers, laterals, and nozzles, weir plates and backwash channels. Where necessary we have
removed, cleaned and reinstalled laterals, pipes and nozzles.
