Water and Sanitation Engineering

Lidwala provides clients with specialist solutions from planning, design, implementation management and commissioning of water and waste water projects; ensuring effective, equitable and efficient water-use.

Fresh water is recognised as a key national supply resource as it is an indispensable finite resource that must be protected and carefully managed for current and future generations to come. Population increase is associated with the decline in water quality and per person availability. This realisation has enormous social, economic and environmental implications and provides a driving force to develop innovating and equitable ways of adapting to the inevitable scarcity. Our water and sanitation team provides our clients with a full range of water-related infrastructure solutions.
