The reuse of rainwater is an important part of water saving. The recycling of rainwater is bound to become the development trend of urban economy, which has played a positive role in promoting the modernization of the city. Of course, rainwater reuse is a huge and long-term system project. It not only requires joint research by various scientific teams, but also the strong support of local government departments and residents. The country also actively advocates the construction of a "sponge city" to allow cities to store rainwater. Alleviating and solving urban water shortages and developing rainwater collection systems are projects that benefit the country and the people. The abandonment device plays an important role in the entire rainwater collection system. The selection of the abandonment method has an impact on the size of the initial rainwater abandonment flow, the control method of the abandonment equipment, and construction and maintenance and engineering cost. Abandonment devices are generally set in rainwater collection

The function of plastic septic tank (1) is not leaking. The product is formed with high-strength acid- and alkali-resistant materials such as high-density polyethylene at one time, and has good sealing performance. It does not cause fracture and breakage caused by ground settlement and scum layer formation in the pool, which solves the groundwater pollution caused by brick septic tanks. Problem, with functions of reliable operation and anaerobic dung. (2) High compressive strength. The product structure design is reasonable, and the pressure is uniform. After more than 200 cycles of testing, the truck will not settle and deform without rolling. (3) Small footprint. The product occupies an area of about 45% of the traditional septic tank, which saves land resources and has the characteristics of flexible site selection. (4) Easy installation and construction. It can be freely combined and installed according to the needs of the site.

Walking on the street, if you observe carefully, the surface of the manhole cover is full of patterns, there are crosses, herringbone, and other patterns, so why must these patterns be printed on the surface of the manhole cover? Let me introduce you: the surface of the manhole cover has a unique non-slip pattern, mainly to increase friction and prevent pedestrians from slipping due to rain, snow and ice cover. Imagine that on a smooth iron plate, when it rains or it snows in winter, it is easy for pedestrians to slip a big heel on it. If the elderly people walk on it, the consequences will be even more disastrous, and it is likely to cause serious consequences and even death. Therefore, the manhole covers manufactured by domestic manhole cover factories now have various patterns on the surface for the purpose of safety and non-slip.

Frequent waterlogging in cities has become more and more serious in recent years, and many cities are even more unrecognizable during the rainy season. For example, several days of heavy rain in Hubei in the past few years have finally caused the road surface of a community to collapse and fall into South Lake. There are also heavy rains in most parts of China at around 8:00 from July 21 to 22, 2012. Among them, Beijing and its surrounding areas suffered the strongest rainstorm and flood disaster in 61 years. As of August 6, 79 people have died in Beijing due to the heavy rain. According to data from the Beijing Municipal Government's disaster briefing, the storm caused 10,660 houses to collapse, affecting 1.602 million people and causing economic losses of 11.64 billion yuan. Since the rainstorm flooded in 2013, many cities have been hit by heavy rain.

Announcement No. 659 of the Ministry of Housing and Urban-Rural Development of the People's Republic of China and Decree No. 109 of the Ministry of Construction clearly stipulate that the use of clay solid brick inspection wells is prohibited and the use of plastic inspection wells is promoted.
