“…The barrel, once filled, does little to further store rainwater, and thus, it needs to get frequently emptied [24]. The barrel cannot reset automatically [25]. Similarly, a traditional rainwater tank is a bigger unit storing rainwater for non-portable water usage [26].…”

Urban flooding has become a serious but not well-resolved problem during the last decades. Traditional mainstream facilities, such as vegetated roofs, permeable pavements, and others, are effective to eliminate urban flooding only in case of small rains because the water-retaining and detaining capacities of these traditional facilities are limited. Here, we propose a new buffer tank buried in soil to deal with rainwater onsite as peak-flow control for urban flooding mitigation. Experiments showed that the buffer tank intercepts the surface runoff and discharges the intercepted water through a designed outlet orifice. By properly setting the cross-sectional area of the orifice, the tank extends the drainage duration several times longer than that of the rainfall duration. It is found that the buffer tank attenuates the peak flow greater at heavier rain. At small rain (<2.5 mm), the tank is always unfilled, preserving storage spaces for detaining rainwater in case of heavy rain. The buffer tank is thus greatly helpful to mitigate the flooding problem, avoiding being saturated by small long-lasting rain.

“…The use of rain barrel is thus challenged not only by barrel size but also homeowner participations [118]. For instance, Guo et al [119] found that people who are aware of rainwater conservation are more willing to adopt rain barrels. Figure 5.…”

Urbanization has replaced natural permeable surfaces with roofs, roads, and other sealed surfaces, which convert rainfall into runoff that finally is carried away by the local sewage system. High intensity rainfall can cause flooding when the city sewer system fails to carry the amounts of runoff offsite. Although projects, such as low-impact development and water-sensitive urban design, have been proposed to retain, detain, infiltrate, harvest, evaporate, transpire, or re-use rainwater on-site, urban flooding is still a serious, unresolved problem. This review sequentially discusses runoff reduction facilities installed above the ground, at the ground surface, and underground. Mainstream techniques include green roofs, non-vegetated roofs, permeable pavements, water-retaining pavements, infiltration trenches, trees, rainwater harvest, rain garden, vegetated filter strip, swale, and soakaways. While these techniques function differently, they share a common characteristic; that is, they can effectively reduce runoff for small rainfalls but lead to overflow in the case of heavy rainfalls. In addition, most of these techniques require sizable land areas for construction. The end of this review highlights the necessity of developing novel, discharge-controllable facilities that can attenuate the peak flow of urban runoff by extending the duration of the runoff discharge.

“…In urban planning, green infrastructure also encompasses urban parks, urban forest reserves, squares, plazas, and street trees, among other urban public vegetated surfaces. This "green movement" grew on the insufficiency of conventional flooding-control solutions based on combined sewage systems and "grey" features such as dikes and levees, and the needs of adaptive management, since they do not solve contemporary environmental problems, tending to cause social and economic harms (Gao et al 2016).…”

Stormwater management (SWM) focuses on reducing runoff volumes and improving water quality. Stormwater is all rainwater or melted snow and hail that runs off pavements, streets, lawns, and other land surfaces and did not infiltrate into the soils or other permeable surfaces. Stormwater is of special concern because of its potential to cause floods and natural disasters. Also, it is a major cause of water pollution in urban areas and a source for water-disease transmission. Excess overland flow is due to intense storms and other severe weather phenomena combined with favorable hydrological conditions and land use issues of the built environment, which ultimately exposes gaps in SWM (McGrane 2016). Storms may also cause landslides. These mass movements eventually flow into streams, rivers, and coastal zones, causing riverbank erosion and potentially worse floods, as all these solid materials and debris reduce or block river flow sections and interfere with estuarine areas. Stormwater is characterized by high turbidity and may carry pollutants that can eventually compromise surface water quality, ecosystems, and human health (UN 2018a). Like other water issues, stormwater is also impacted by people's attitude and behavior towards waste disposal and other interactions with the natural and the built environment. Eventually, these will cause stormwater impacts upon ecosystems and societies.The importance of SWM is recognized in several ways within the UN 2030 Agenda for Sustainable Development and in the 17 Sustainable Development Goals (SDGs). SWM is within SDG 11 (Sustainable cities and communities). However, it directly relates to goals 6 (Clean water and sanitation), 15 (Life on land), and 13 (Climate action), and correlates mainly with goals 3 (good health and well-being), 9 (industry, innovation and infrastructure), and 14 (life below water). Sustainable SWM has an important impact on reducing poverty and ending hunger (UN 2018a). Nonetheless, the goals are broad-based and interdependent. To make SDGs successful, it is of central importance that the data regarding the 17 goals be available and understandable.
