雨水貯留の世界市場規模：貯留方法別、用途別、地域範囲別、予測

雨水貯留の市場規模と予測

雨水貯留市場の市場規模は、2024年に10億3,793万米ドルと評価され、2026～2032年にかけてCAGR 5.89%で成長し、2032年には15億7,360万米ドルに達すると予測されます。

雨水貯留とは、屋上や空き地などに降った雨水を集め、貯留し、利用する簡単なプロセスです。降った雨をそのまま流出させるのではなく、再利用するために雨水を集め、その場所に貯留します。集められた雨水はタンクや貯水槽に貯められ、景観の灌漑、飲料水や非飲料水の屋内利用、雨水管理など、さまざまな用途に利用されます。

雨水貯留は、代替の水源がない場合や、現在の水源が不足している場合、あるいは水質が低い場合に特に有効です。雨水貯留は、水を節約するための最も効果的な技術の1つと考えられており、掃除、洗濯、入浴、料理、その他の必需品など、家庭内のさまざまな機能に利用することができます。

世界の雨水貯留市場力学

雨水貯留市場を形成している主要市場力学には以下が含まれます。

主要市場促進要因

水不足とストレスの増大：水不足とストレスの増大：水不足の深刻化に伴い、雨水貯留装置の人気が高まっています。国連世界水開発報告書2023によると、世界の水需要は2050年までに20～30％増加すると予想されています。同報告書によると、水不足は世界で20億人以上に影響を及ぼしており、この数字は2025年までに30億人に上ると予測されています。このような水不足の深刻化により、雨水貯留などの代替水源に対する需要が高まっています。

節水を促進する政府の取り組みと規制：多くの政府が雨水貯留を促進する施策を打ち出しています。例えば、インド政府のジャル・シャクティ省は2023年、全国的な節水プログラムの結果、都市部における雨水貯留システムが過去2年間で35％増加したと発表しました。同様に、オーストラリア気象局は、政府による雨水タンクへの払い戻しにより、2021～2023年にかけて家庭用雨水貯留システムが40％増加したと報告しています。

サステイナブル水管理に対する意識の高まり：環境問題への関心が高まるにつれ、雨水貯留システムの人気は高まっています。世界資源ラボによると、2020～2023年にかけて、雨水貯留など水効率の高い技術への世界の投資は年率28％増加しました。また、国際水協会が実施した調査によると、富裕国の都市計画担当者の65％が、新規開発プロジェクトに雨水貯留システムを組み込んでおり、2020年の45％から増加しています。

Rainwater Harvesting Market Size And Forecast

Rainwater Harvesting Market size was valued at USD 1037.93 Million in 2024 and is projected to reach USD 1573.6 Million by 2032, growing at a CAGR of 5.89% from 2026 to 2032.

Rainwater harvesting is the straightforward process of collecting, storing, and utilizing rainwater that falls on rooftops, open spaces, and other surfaces. Instead of allowing rainfall to flow off, it is collected and deposited on-site for reuse. The collected rainwater can be kept in tanks or cisterns for a variety of purposes, including landscape irrigation, potable and non-potable indoor use, and stormwater management.

Rainwater harvesting is especially beneficial when there is no alternative source of water supply, or when the present supply is insufficient or of low quality. It is regarded as one of the most effective techniques to conserve water and may be used for a variety of domestic functions, including cleaning, washing, bathing, cooking, and other necessities.

Global Rainwater Harvesting Market Dynamics

The key market dynamics that are shaping the rainwater harvesting market include:

Key Market Drivers

Growing Water Scarcity and Stress: Rainwater collection devices are becoming increasingly popular as water scarcity grows. According to the United Nations World Water Development Report 2023, worldwide water demand is expected to rise by 20-30% by 2050. According to the report, water stress affects more than 2 billion people worldwide, with the figure anticipated to climb to 3 billion by 2025. This increasing water scarcity is driving demand for alternative water sources such as rainwater collection.

Government Initiatives and Regulations Promoting Water Conservation: Many governments are establishing policies to promote rainwater gathering. For example, in 2023, the Indian government's Jal Shakti Ministry announced that their national water conservation program resulted in a 35% increase in rainwater harvesting systems in urban areas over the previous two years. Similarly, the Australian Bureau of Meteorology reported that government reimbursements for rainwater tanks resulted in a 40% rise in household rainwater harvesting systems between 2021 and 2023.

Rising Awareness of Sustainable Water Management Practices: Rainwater harvesting systems are becoming increasingly popular as people become more environmentally concerned. According to the World Resources Institute, global investment in water-efficient technology, such as rainwater collection, increased by 28% per year from 2020 to 2023. Also, a survey conducted by the International Water Association discovered that 65% of urban planners in wealthy nations now incorporate rainwater collecting systems into new development projects, up from 45% in 2020.

Key Challenges:

High Installation and Maintenance Costs: The initial cost necessary to install a rainwater harvesting system is high, particularly for large-scale projects. This is a hurdle for certain people and organizations, especially those with low resources. Also, regular upkeep is required to guarantee the system runs properly, which increases the ongoing costs.

Lack of Awareness and Education: Many places still lack awareness of the benefits and significance of rainwater gathering. Without sufficient teaching and promotion, the adoption of these systems is gradual. Governments and organizations should invest in awareness efforts to highlight the benefits of rainwater gathering and encourage widespread adoption.

Key Trends:

Increasing Adoption of Green Building Practices: Rainwater harvesting systems are becoming more popular as the emphasis on sustainable construction and smart city development grows. Green construction programs and government regulations encourage the use of rainwater harvesting as a water-saving measure in both residential and non-residential settings.

Technological Advancements and Product Innovation: Manufacturers are constantly innovating and creating improved rainwater collecting systems to meet the different needs of clients. These include sophisticated monitoring systems, self-cleaning filters, and modular designs that allow for flexible installation. The availability of a diverse range of products, from simple to complicated systems, is drawing a larger client base.

Rising Demand from the Commercial and Industrial Sectors: The nonresidential market, which includes commercial and industrial uses, is likely to increase significantly in the future years. Rainwater harvesting systems are becoming more common in commercial buildings as water conservation laws and the need for alternate water sources grow. Industrial sectors are also implementing these systems to lessen their reliance on municipal water sources while meeting their water needs.

Global Rainwater Harvesting Market Regional Analysis
