Stormwater Harvesting Systems Describe U.S. Water Conservation Efforts

The stormwater harvesting system industry is rapidly emerging in the area of ​​sustainability. The world today receives an annual precipitation of about 100 cm, or about 39 inches. However, this is distributed very unevenly. This means that parts of Southeast Asia or the equatorial zone experience the highest rainfall, while some countries and places in Africa receive as little as 2 inches of precipitation per year.

It would be surprising to note that despite these numbers, a huge amount of rainwater is wasted around the world due to lack of rainwater management and awareness of the ongoing water crisis, which adds to the statistics of water scarcity. In 2017, nearly 884 million people did not have access to drinking water.

In fact, the United Nations has estimated that by 2025, two-thirds of the world’s population will face a severe scarcity of fresh water. These figures have raised alarming concerns among various states as well as among central governing bodies, allowing them to come up with the idea and concept of rainwater harvesting. A recent breakthrough in this concept was made in the United States, by Texas A&M AgriLife Extension Service.

According to an Agrilife Today article, the Healthy Lawns and Healthy Waters program run by the educational agency is expected to host a rainwater harvesting and turf organization program for residents of Gillespie, Kerr and Kendall counties at the start. of May. The online event is offered in alliance with the Upper Cibolo Creek Watershed Partnership.

It has been estimated that the global market for rainwater collection system would represent an annual compensation of $ 7.9 billion by 2027. Developed and emerging economies are expected to experience a sustained pace of technology adoption.

What are the advantages of rainwater harvesting?

But why opt for rainwater harvesting? “Sustainability is the need of the hour”; an important fact that implies that the common practice of collecting rainwater can help residents store water for future use. It can be used to invigorate water at ground level and improve its quality. Even more, rainwater harvesting controls surface water runoff, while reducing soil erosion.

Speaking of surface runoff collection, this potential type of rainwater harvesting is the collection, accumulation, treatment and storage of stormwater for eventual reuse. The water thus obtained is an exceptional alternative to the use of main drinking water for various purposes.

Industry professionals say that if properly designed, surface runoff catchment systems can boast the ability to collect large amounts of rainwater. That said, the surface runoff harvesting market share is expected to register a substantial CAGR of 3.7% between 2021 and 2027.

Stormwater management grows in the United States with stormwater harvesting systems

Recently, the Arlington County Department of Environmental Services, in response to increasing storms, flooding and ongoing development, announced overhaul of its stormwater management regulations for single-family home construction projects. . It has been suggested that the team would require developers to use tools like water storage tanks to ensure new homes can hold at least 3 inches of rain, which could potentially affect claims submitted afterwards. September 13, 2021.

Climate change, a buzzword in today’s era of global warming and globalization, has been shown to cause extreme rainfall in recent years. The effects of these adverse weather events have indeed resulted in massive costs incurred in the affected areas in terms of destroyed infrastructure, casualties and economic damage.

In fact, since 1980, each of the hurricanes that have hit parts of the United States has resulted in a cumulative cost of $ 870.2 billion. In view of these discouraging statistics, a variety of stormwater management strategies and initiatives, based on stormwater harvesting systems, have been developed to reduce the severe impact of urban runoff as a result of these conditions.

Apart from this, a number of national stormwater management strategies, including water-sensitive urban design and sustainable drainage system (SuDS), were also seen as beneficial tools. Smart urban cities can use them to reduce the pressure from extreme storms on their drainage systems.

In April 2021, the city of Wausau, Wisconsin announced a rain barrel system program. Homeowners connect the roof spout to the rain barrel to collect precipitation and establish a natural water supply cycle, rather than letting rainwater flow into wastewater. This water is considered better for plants and other similar uses compared to municipal treated tap water. The city will charge $ 50 for barrels for residents and $ 75 for non-residents.

Many cities across the country are adopting rainwater harvesting programs to encourage people to adopt affordable and practical solutions. The barrel system gains an advantage over a few other harvesting systems due to the low initial cost.

Germany – At the forefront of rainwater harvesting

The average annual rainfall in Germany ranges from 563 mm to 855 mm. This has allowed the authorities to focus strongly on promoting household rainwater harvesting, particularly at the local government level. It is predicted that the country will occupy a leading position in the industry of rainwater harvesting systems in Europe until 2027.

One of the main benefits associated with the development of stormwater harvesting systems is that many German cities charge homeowners a stormwater drainage fee, which is usually waived if the runoff is retained in the ground, which allows significant savings. In fact, the country is a plethora of government-level rainwater harvesting projects and developments. One of them is the rainwater harvesting at Frankfurt Airport.

Frankfurt Airport in Germany has one of the largest rainwater harvesting systems in the country. According to official sources, the system helps the country save around 100,000 cubic meters of water per year. The cost of building the system was approximately US $ 63,000 in 1993.

The world is currently facing a critical need to tackle the problems of climate change and water scarcity with sustainable water conservation strategies and solutions. The idea of ​​rainwater harvesting is expected to become a lucrative opportunity for environmentalists and various governing bodies in 2021 and beyond.
