Centralised wastewater systems are the most widely applied in well-developed urban environments and the oldest approach to the solution of the problems associated with wastewater. They collect wastewater in large and bulk pipeline networks (also referred to as\u00a0sewerage) which then transports it at long distances to one or several treatment plants. The size of the centralised network allows for applications of different conveyance methods, in addition to the well-known gravity sewers, such as pressurised sewers and\u00a0vacuum sewers.\u00a0\u00a0Storm water\u00a0can be collected in either\u00a0combined sewers\u00a0or in a separate storm water drains. The latter consists of two separate pipeline systems, one for the wastewater and one for the storm water. The treated effluent is disposed in different ways, most often discharged into natural water bodies. The treated effluent may also be used for beneficial purposes and is referred to as\u00a0reclaimed water [1].<\/p>\n\n\n\n

The main difference between decentralised and centralised systems is in the conveyance structure. In decentralised systems, the treatment and disposal or reuse of the effluent is close to the source of generation. This results in a small conveyance network and in some cases is limited only to one pipeline in comparison to a full network for a centralised system.<\/p>\n\n\n\n

These sewage systems offer users an efficient and exceedingly hygienic sanitation solution at literally the press of a button (flush). The faecal water is screened and treated away from the site before being put back into its initial or other water source. This connection of all households and buildings ,along with the treatment process connected by a sewerage system, means that the users rarely have to consider the problem of sanitation [2].\u00a0<\/p>\n\n\n\n
