Drainage involves the natural or artificial removal of any sub-surface water from a space. Water supply, on the other hand, involves ensuring that residential, commercial and public spaces have a clean, safe and regular supply of water, usually via pipes and pumps.

Functional, safe and reliable Drainage and Water Supply systems are essential elements in any environment including hotels, residential and commercial properties, schools, shops, and gyms.
