Commercial facilities will need to provide a large number of parts to different customers and staff; the scope of the work of a commercial plumber goes far beyond domestic plumbing work.

The two main areas of Plumbing are Domestic and Commercial. Domestic meaning that you will be working on all aspects of water and drainage in buildings where people live. Commercial meaning shops and businesses as well as industrial sites and public water facilities.

Plumbers and the plumbing industry help us optimize our water usage through technology and water management. They work to ensure there's always enough water to go around. They also play an important role in taking actions such as harvesting rainwater, desalination, wastewater treatment, and water reuse.
