Our core business is the installation and maintenance of water and waste water treatment technologies including pump stations. These installations include but are not limited to chemical systems, raw water, treated water, supernatant, backwash, and Ultra Filtration and Reverse Osmosis systems.

These systems include installation of pipe work ranging from 15mm to 750mm in PVC, stainless steel, Ductile Iron, HDPE, ABS etc. We also install all mechanical equipment including valves, pumps, air compressors and blowers.

G&M Plumbing has all the necessary tools to carry out these works and while we have the workforce with the necessary tickets to drive/operate the various excavators and other machinery we do hire the machines as required.

To accompany this suite of works we supply, fabricate and install various steel works such as dosing system cabinets, pipe stands and other welding and fabrication services as required. We have fully ticketed trades people for welding. See attached some photos of previous works.
