Application of Composite Correction Program for improvement in efficiency of water treatment plants - A WHO paper
Safe drinking water, sanitation, water purification, secured supply, are all unchecked on goals' checklist; emphasizing on the need of intricate tools and plans and their implementation. Posted on 20 Apr, 2011 12:41 AM

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.
