Privatization of water supply in the country is another method which can be used by the government to resolve the water supply problem. The government can transfer the process of water supply to private players. Private players are value driven, posses requisite skills and have the potential to transform unviable water treatment systems into feasible water systems. Privatization would bring in expertise, human capital and enhanced water treatment based technologies for water treatment and purification. Under this process, government would be transferring ownership rights to private players. The advantage of this method is scope for improvement in water supply through use of experience and technology of private players. However, imminent risk involved in this process is focus on profit generation rather than water supply in the country by private players. Operational and maintenance components used would be of higher quality (Hazelton, J., 2014). Under this process, periodical cleaning of water supply chain and pipes would take place for removing oily material and accumulated algae. Moreover, an effective waste management would be developed for removal of waste from the water. Proper drainage and disposal of waste materials would be developed under privatization method. Moreover, the government would push private players for setting up of preventive maintenance program. This would be primarily done for increasing effectiveness and efficiency of water treatment system and increasing their duration. Private players would ensure optimum utilization of available resources for water treatment and water distribution. In this method, the government runs the risk of biased allocation of safe water by private players to specific areas in the country. Privatization brings efficiency in the system through maximization of benefits, management of various resources and involvement of intellectual capital.
兼性泻湖一般采用水处理-泻湖技术进行水处理。这种水处理工艺是从稳定池发展而来的，使用机械或扩散空气系统。该方法不能用于高出水固体含量超过100 mg/l的水容器。为了防止水质退化，已经发展了水文控制性泻湖。在这一过程中，废水在河流禁止排放后聚集在泻湖中(Chalmers, K。戈弗雷,J。林奇,B。,2012)。这种方法最重要的优点是，如果需要，可以提供额外的水处理。人工湿地可以通过地表水和地下水两种不同的形式来利用。这些系统需要植物的根和养分来转移氧气。这些系统用于狭长流域的水处理，并作为水生植物的蓄水池。此外，在水处理过程中还可采用间歇式和循环式滤砂器。然而，这两种方法在水处理中的应用由于废水的应用而有所不同。循环过滤器可用于生物水处理(Huq, F。史蒂文森,M。Zorzini, M。,2014)。
They convert nutrients into different forms of scarce bio-mass. Mechanical water system uses combination of various processes including biological, physical and chemical for water treatment and purification. This method uses natural water treatment process in human constructed environment (Habiba, U., Abedin, Md., Shaw, R., (2014). The mechanical water treatment methodology uses various components including tanks, pumps, pipes, grinders and blowers. Flow of water in the system is controlled through various mechanical techniques for treatment of waste water. This method is highly effective where there is scarcity of land.
Facultative lagoons are generally used for water treatment through aquatic treatment-lagoon technology. This water treatment process evolved from stabilization ponds and uses mechanical or diffused air systems. This method cannot be used for water containment with high effluent solids exceeding 100 mg/l. Hydrograph controlled release (HCR) lagoons have been evolved for prevention of water quality degradation. In this process, waste water gets accumulated in a lagoon after stream prohibits discharge (Chalmers, K., Godfrey, J., Lynch, B., 2012). The most important advantage of this method is provision for additional water treatment, if required. Constructed wetlands can be utilized in two different forms either through use of surface water flow and subsurface flow. These systems require roots of plants and nutrients for transfer of oxygen. These systems are used in long, narrow basins for water treatment and serves as a water reservoir for aquatic plants. Moreover, sand filters including intermittent and recirculating sand filters can be used in water treatment process. However, application of both these methods in water treatment differs due to waste water application. Recirculating filters can be used for biological water treatment (Huq, F., Stevenson, M., Zorzini, M., 2014).
