In urban areas, the population may be entirely reliant on the public water supply system for their drinking water. Modern water treatment works (WTWs) rely on inputs of chemicals, electricity and skilled operators as well as the constructed plant and machinery. Clean water then needs to be delivered but piped systems can be prone to leaks, intermittent operation and contamination. Managing a water supply system is a complicated task and it is strongly recommended that a suitably qualified engineer is responsible for the rehabilitation of any system.
