Research On The Assessment System For Water-Saving Residential District In Zhuhai

There are many population in China,our country has always been very thirsty.Amount of fresh water resources in our country of two trillion eight hundred billion cubic meters,accounting for six percent of global water resources,second only to Brazil,Russia and Canada,ranked fourth in the world.However,China's per capita water resources is only two thousand three hundred cubic meters,is only a quarter of the world average,is one of the poorest countries in the world per capita water resources.Water is the inseparable part of people's life,with the development of The Times,the urban life-water quantity presents the increasing trend year by year,the waste water in the life in the residential district also has become increasingly serious.Water supply system overpressure outflow,the phenomenon such as pipeline leakage,the unreasonable water apparatus,bad water habits will result in the waste of water resources.Aiming at these problem's put forward the concept of construction of water-saving buildings,water-saving technology has carried on the analysis and research to the article.This article main research aspects including water-saving appliances,reclaimed water technology,modern rainwater harvesting technology,building community water supply pipe network optimization and establishing water-saving construction evaluation index.Water-saving appliances is mainly introduced the water saving,water-saving toilet,water-saving shower,water-saving washing machines and other commonly used water appliances,daily life from using aspects,water control,to achieve the goal of water saving.Reclaimed water technology is the focus of the life of mixed water drainage,sewage recycling,such as through simple processing,make originally should the reclaimed water back flushing for village,green,etc.,the water is saved and also save on the economy.Rainwater utilization technology is fully utilized the rain this free resource,simple processing will rain,for building communities,flushing,or water use,not only beautify the community environment,and to save water.Water supply pipe network of water supply network optimization is through the rationalization and the optimization of water supply pipe and accessories to avoid the overpressure outflow,the phenomenon such as pipeline leakage,reduce the amount of waste water from the source.With the building area of water-saving measures,how to measure the effect of water saving measures are equally important,it is need to build a suitable evaluation system.Through the analysis of a series of existing evaluation system at home and abroad,the selected scheme is more suitable for China's national conditions to evaluate.This article recommended the “Green Building Evaluation Standard”,the construction of water-saving index for grading scores,ultimately for building community water saving effect is given a reasonable evaluation.
