It is characterized by The total management of wastewater can be separated into four categories: • wastewater collection, • wastewater treatment, • treated wastewater disposal and, • sludge management. It is simply that we have now placed effective barriers - our wastewater control infrastructures - between these activities of society and the surrounding environment. wastewater management must be an integral part of rural and urban economic development, jobs and consequently poverty reduction. Optimizing agricultural practices including irrigation techniques, And just as there would be a concern for the long-term reliability of a dam structure for a water reservoir, so there must now be an increasing concern for the reliability of our wastewater control infrastructures. Its disadvantages however include odour problems and it requires a, large area of land to function properly. Such concern is generic: transient perturbations about an equilibrium are as relevant to agricultural and silvicultural control infrastructures as they are to our systems of urban sewerage and wastewater treatment. reflects the amount of all forms of phosphorous in a sample.
