Introduction There is a distinct difference between the meaning of the words sanitation and sewage. The word sanitation means the safe removal of human excrement in a way that protects the health of the user and the environment. To be safe and hygienic, a sanitation system must prevent people from touching the excreta, prevent flies from coming into contact with the excreta and also remove any smells or bad odours. The word sewage refers to human excrement and other waste from houses, buildings or factories which are carried away from the source in a stream of water, be it in a canal or closed conduit such as a pipe. This is the derivation of the word wastewater water transporting waste. Natural disasters such as floods, and man-made incidents, for example catchment chemical/sewerage spills and bacteriological contamination, can communication plans in place. Emergency protocols and communication plans needed during Waste water failures: Key stakeholders are kept fully informed; 1. Roles and responsibilities of individuals and organisations are clearly outlined to avoid miscommunication and duplication of effort; 2. Timeous interventions are taken to rectify the situation; and 3. Affected communities are properly informed and have alternative safe drinking water for the duration of the problem. 4. Emergency protocols and communication planning are therefore critical in minimising public health risks associated with drinking water failure. Basically actions and protocols should be developed in consultation with relevant regulatory authorities and other key agencies. It is vital that protocols are developed prior to the occurrence of any incident or emergency to enable efficient, effective and rapid response that will minimise the impacts on the community. Establishing procedures when emergencies occur is a recipe for disaster and the potential loss of public confidence. and emergency response protocols must be communicated to all relevant personnel and copies of documented procedures must be available. Refer to the below s procedure as stipulated by each alert level: 3

Conclusion Water is everywhere, in us and around us, in liquid, solid or gas form. Take a moment and consider how wonderful water truly is! A sparkling lake on a hot summer s day, ice cubes clinking in your glass of cool drink, a hot shower on tired muscles, gentle rain feeding our gardens and refreshing our souls. We rely on water each and every day for our very lives and wellbeing. But, the water we have on Earth is finite and the amount of water that is available for human consumption is actually reducing due to many wasteful or polluting practices. So it is highly important to ensure Water quantity and quality incidents should be addressed as soon as possible as stated to above incidents management protocols and it is responsibility of each and every official to ensure proactive mechanisms be implemented avoid reactive mechanisms.
