Treatment and Purification

The goal of safe and affordable drinking water and sanitation has not yet been achieved. The current practices of water purification are inadequate to produce secured water supply. Maintaining health protection at water supply systems has become more challenging with resistance of some pathogens to disinfection using chlorination and an increase in the immuno-compromised population (e.g., people with HIV, organ transplant patients, the elderly).

In this context, it has become essential to develop various tools such as Composite Correction Programme (CCP) and Water Safety Plans (WSP) to improve water purification and distribution systems, to achieve the goal of providing safe drinking water.

The quality of drinking water is a vital element of public health and well-being. The most effective means of consistently ensuring the safety of a drinking-water supply is through the use of a comprehensive risk assessment and risk management approach that encompasses all steps in water supply from catchment to consumer.

WHO guidelines on water quality term these approaches as water safety plans (WSPs), developed to organize, systematize and apply management practices in drinking-water quality.
