Rainwater Harvesting Market Size

Rainwater Harvesting Market size surpassed USD 6 billion in 2020 and will grow at a CAGR of 4% between 2021 and 2027. Rising water scarcity coupled with growing population across the globe will drive the market demand.
 

The surging consumption of water in the agriculture sector is also likely to propel the rainwater harvesting market expansion. Moreover, factors, such as expansion of business activities, urbanization, and global climate change, are stressing the water supply across the globe. Rainwater harvesting is a vital technique, which helps to mitigate this impending water scarcity.
 

Governments in several countries have started to implement RWH policies to encourage water conservation. Some of the states in countries including the U.S., Australia, Singapore, Thailand, India, and Germany have mandated the installation of rainwater harvesting systems in new construction buildings.
 

Rainwater Harvesting Market Analysis

The rooftop rainwater harvesting segment will dominate the market share through 2027, owing to its low product price and simple technique. Additionally, it offers various advantages such as high-quality water, easy to construct, operate, and maintain. Besides these, rooftop rainwater harvesting also reduces the cost of pumping groundwater.
 

The surface runoff segment is projected to grow significantly at a CAGR of 3.7%, in terms of revenue during the forecast period. This growth is majorly attributed to its advantage that it can collect large quantities of rainwater.
 

The residential sector in the rainwater harvesting market is projected to exceed USD 3.4 billion revenue by 2027, attributed to growing usage of water and rising acceptance of the product in residential applications across the globe. Additionally, the commercial applications of these systems are projected to grow significantly mainly due to the rising awareness regarding great benefits and cost effectiveness of these systems for commercial buildings including schools, resorts, restaurants, hotels, office buildings, and hospitals.
 

The dry systems segment will hold a rainwater harvesting market share of over 35% by 2027, led by the rising application of these systems in residential and commercial sectors. Generally, the installation of a dry system is quicker and cheaper than a wet system. Additionally, it is a very simple system to install. Dry systems require low maintenance as the pipes automatically dry out between rain events and stop the build-up of contaminants.
 

The wet systems segment is likely to witness a decent growth rate till 2027, credited to high product cost and frequent maintenance. The wet system produces high-quality drinking water and offers aesthetic looks than a dry system. This is because there are minimal pipes visible, usually only the gutters and downspouts.
 

The direct pumped system held close to 45% rainwater harvesting market share in 2020. This system is generally the easiest to install and is the most common type of more professional rainwater harvesting systems, particularly for domestic applications.
 

The installation of an indirect pumped system will observe strong growth of more than 3.8% from 2021 to 2027, due to its great flexibility as the booster pump can be adjusted to meet the building's flow and pressure requirements.
 

Asia Pacific rainwater harvesting market accounted for around 40% revenue share in 2020, on account of growing population especially in India and China along with rising need for water in agricultural and residential sectors. The growing awareness regarding the benefits of rainwater harvesting systems and a surging need for water conservation due to the rising water scarcity in many Asian countries are further driving the regional industry growth.
 

Germany dominated the European rainwater harvesting market share in the coming years, owing to rising interest in promoting household rainwater collection mainly at the local government level. Additionally, there are grants and subsidies in several towns & cities in Germany to allow householders to create rainwater tanks and water wells.
