“…However, the capacity of rainwater tanks to reduce discharge rates from connected roofs is generally not fully utilized in practice, as they are commonly not empty during storm events [22]. This limitation can be overcome with the aid of smart technologies, which enable rainwater tanks to be emptied based on knowledge of impending rainfall events, thereby maximizing available retention storage [14,[23][24][25]. For example, South East Water (Melbourne, Australia) use controlled outlets to empty rainwater tanks before a forecasted storm event, which can maximize retention capacity to reduce peak flows [26,27].…”

Urban water systems are being stressed due to the effects of urbanization and climate change. Although household rainwater tanks are primarily used for water supply purposes, they also have the potential to provide flood benefits. However, this potential is limited for critical storms, as they become ineffective once their capacity is exceeded. This limitation can be overcome by controlling tanks as systems during rainfall events, as this can offset the timing of outflow peaks from different tanks. In this paper, the effectiveness of such systems is tested for two tank sizes under a wide range of design rainfall conditions for three Australian cities with different climates. Results show that a generic relationship exists between the ratio of tank:runoff volume and percentage peak flow reduction, irrespective of location and storm characteristics. Smart tank systems are able to reduce peak system outflows by between 35% and 85% for corresponding ranges in tank:runoff volumes of 0.15–0.8. This corresponds to a relative performance improvement on the order of 35% to 50% compared with smart tanks that are not operated in real-time. These results highlight the potential for using household rainwater tanks for mitigating urban flooding, even for extreme events.

Water conservation is critical because it is one of the most significant factors for all species' survival. According to the Central Ground Water Board's estimates, underground water will be scarce in 15 Indian states by 2025 [1]. However, as per the report from Ministry of Environment and Forest, only 10 to 20% rainwater is harvested. In urban areas, it is seen that nowadays concrete structures are constructed everywhere, so it is not possible to recharge the water table by natural process of raining. All the rainwater which is one of the sources for fresh water goes to drain. This causes the depletion of groundwater level which may be fatal in the future. Therefore, a rainwater harvesting system is required in Indian household to conserve water. On the other hand, the urban cities are having high pollutant levels which in turn affecting the quality of water. The government has defined certain parameters for quality checking of water. With the aid of the suitable sensors and IoT boards, quality checking, monitoring and water segregation can be easily achieved. In this work, an efficient and cost effective technique of rainwater harvesting has been presented. Some real case studies have been done at Indian houses in order to validate the effectiveness of system in terms of its implementation and cost analysis. As a result, the proposed system becomes one of the smart solutions to address the modern problem of rainwater harvesting with water quality management in low cost.

“…The water sensor decides the operation of the signals that are sent to the Arduino, servo engine is launched by the Arduino and the end goal is to make water accumulation open, this also triggers an electronic mail to indicate its status to the user. Martin Oberascher et al, [10] Smart rain barrels are made to be used for temporary storage and control of storm water. They can also be used for harvesting rainwater.…”

Rainwater harvesting is one of the oldest practices used to conserve and optimize water resources. Nowadays, there are a lot of public and private facilities which have well-constructed Rainwater Harvesting systems. Still, they usually can't test the quality of the water preserved and has no mechanism to purify the impure content to make them consumable. Many known techniques are primitive and conventional for today's standards. The existing systems don't provide connective features, water treatment or contingency measures to counteract any problem. Usually, these systems are integrated onto blockchains, AI, and some other domains to innovate a new paradigm. Still, the results are generally considered a gimmick and are not helpful for general usage. This lack of compatibility and features with no effective solution needs to be rectified, and a real-world upgrade is required to construct a connected, safe and effortless system is imminent. Therefore, an integrative domain approach is necessary to facilitate the process to tackle these problems, where one of the major domains in technology, such as IoT, is used. The proposed model addresses the issues native to the conventional method and provides a connective environment with water treatment capabilities to establish an effortless and connected Rainwater Harvesting system through IoT with precise results and scopes that help the said challenges.
