The long run, can learn from the advanced experience in the field, to encourage social and private capital investment in water pipeline construction, it is recommended that a qualified enterprise units use precision filter in water reuse system, the unit of work is done on water utilization, given certain subsidies or reward. Water, also known as reclaimed water, recycled water, urban sewage and industrial waste water purification treatment compliance, non-potable water can be used within a certain range. The city s severe water shortage, water reuse or Sunshine City "thirst" can become another way. Water reuse by the degree of attention is not enough, Oura only sewage treatment plant up to 10 million tons of daily waste water treatment, the water quality has reached the national secondary effluent standards, water can be used for landscaping, sanitation. But in addition to a small amount of the precision filter processing by the sewage treatment plant own use, the rest were discharged directly into Oura River and flow into the sea.

In addition, in recent years, the city s green coverage continue to improve, as of the end of last year, the city urban green space area of 3910 ha, Greenland has reached 37.3% in built-up areas, so much green ma terial, only a small part of the river watering; same time, due to no specialized pipes and equipment, urban sanitation water almost all use of tap water. Currently, the city daily amount of irrigation water and sanitation, clean water for urban green space over tons. The utilization rate is only about 10% water, schools, residential areas and other reuse water also few.non woven fabric

Water reuse is a general trend, the Urban and Rural Construction departments have "three simultaneous" review into the approval process for construction projects, water-saving appliances, water-saving facilities supporting the provisions of errant allowed to start construction; pair up to not to water-saving standards require the rectification period; rectification is still not standard, the water sector is not a water supply, and in accordance with the provisions to be some punishment. For w ater reuse, currently available in the form of the "water of cars", took the lead in the promotion of landscaping, sanitation, construction and other fields, Line pipe to provide water services for the enterprise.

In recent years, the city of urban and rural construction and water conservancy departments has been advocating the filter in water recycling and the construction of a number of demonstration projects, but the actual use of the situation, and not really to promote open. Point City water shortage, the per capita possession of water resources is only 390 cubic meters, far lower than the national per capita consumption, how to maximize water conservation, has been one of the hot topics. Water reuse in the trend of the times, the relevant departments actively promote water reuse money and the environment, why is it difficult to promote, According to City Jieshui Ban staff, mainly because of water reuse large upfront investment, residential construc tion set water reuse systems, precision filter needs tens of thousands, plus one of the filter device requires a minimum investment of several million dollars, profit-maximizing developers generally unwilling to invest.
