The global water desalination equipment market size was valued at USD 8.68 billion in 2021 and is projected to grow from USD 9.36 billion in 2022 to USD 16.81 billion by 2029, exhibiting a CAGR of 8.7% during the forecast period. The market is surging due to rising water scarcity, technological advancements, government initiatives, and increasing demand for clean water. These factors contributing to the growth of market globally.

The global COVID-19 pandemic has been unprecedented and staggering, with water desalination equipment experiencing lower-than-anticipated demand across all the regions compared to pre-pandemic. Based on our analysis, the global market exhibited a decline of -25.9% in 2020 as compared to 2019.

Water desalination uses seawater, brackish water, river water, and others to produce freshwater. It is an incremental open-source technology to realize the utilization of water resources. It is required to process and produce freshwater, which includes various configurations of Reverse Osmosis (RO) and multi-effect evaporators for treating sea or other water sources. The demand depends on the new plant construction and existing plant development or service. Globally, there is a continuous increase in the desalination installed capacity, which drives the market.


Decline Investment in the Water Sector amid COVID-19 Pandemic to Hamper Market Growth

The outbreak of COVID-19 is likely to slow investment in the water sector worldwide. The importance of operational reliability has also increased due to the cost of disruptions. These operational needs arise from shifts in demand patterns, supply disruptions, and governments' various contingency measures to deal with the pandemic. The world's poorest received the COVID-19 shock on top of large urban water and sanitation deficits, all of which point to a potentially overwhelming burden to contain the virus. Poor access, reliability, and the quality of Water, Sanitation, and Hygiene (WASH) pose risks in developing countries. Large cities also face risks stemming from population densities and informal settlements. A recent World Bank tool for identifying pandemic “hotspots” pointed to cramped urban living conditions and inadequate public services, particularly poor waste management and sanitation, as significant sources of risk of contagion in large emerging markets such as Cairo and Mumbai.

In addition, various construction sites and manufacturing companies were closed during the COVID-19 pandemic in 2020, hampering the demand for water desalination equipment. However, as the world returned to normal since the beginning of 2021, the demand for water desalination plants is expected to increase as governments of different countries plan to invest in water treatment solutions to meet water shortage problems.

Desalination Sector Shifting toward Renewable for Sustainable Production is Growing the Demand for Water Desalination Equipment

The whole world is focusing on the adoption of renewables across every sector to reduce the intensity of greenhouse gas emissions. The water desalination market is also not behind in renewable energy adoption. In a desalination plant, the energy required per kiloliter is about 3 kWh typically these days. Fossil fuel-based energy dominates the global desalination market. According to the World Bank statistics, in 2021, energy prices increased by over 80% compared to 2020, and the scenario continues. The primary reason behind the upsurge in energy prices is an uptick in commodity prices for coal and natural gas. On the other side, as per the International Renewable Energy Agency (IRENA) report, 62% of the renewable energy added in 2020 had lower costs than cheapest fossil fuel alternatives. Currently, solar and wind energy sources are anticipating high growth in terms of consumption due to low cost and meeting net-zero emission targets. 

The trend of producing water sustainably encourages water desalination companies across the globe to utilize renewable power. Many Seawater Reverse Osmosis (SRWO) desalination projects are coming or already in operation using photovoltaic solar as a primary energy source. For instance, Yanbu-4, a desalination project in Saudi Arabia with a 450,000 m3/day capacity, will utilize photovoltaic solar for its SWRO plant, and the plant will come into operation by 2023. With the growing utilization of renewable energy, the requirement for renewable (solar, wind power, geothermal) based desalination systems is also increasing steadily.


Depletion of Freshwater Leads to an Increase in Requirement for Desalinated Water

Freshwater, or drinking water, has become scarce over the years, making people more dependent on its accessibility. Even in countries with adequate water resources, water scarcity is not uncommon due to poor management of water resources, conflicts, and climate change, among other factors. According to UNICEF, at least one month each year, almost two-thirds of the global population experiences severe water scarcity. Still, over two billion people across the globe lack access to safely managed drinking water at home.

Moreover, only 3% of water on the earth is freshwater, and among that about two-thirds is unavailable for use or frozen. People still suffer from waterborne diseases due to less availability of freshwater in several areas globally. It has also been observed in the past half-decade that the death counts due to unsafe drinking water have increased. Several countries' governments are setting up water desalination plants to overcome the scarcity of freshwater. Currently, there are over 18,000 water desalination plants across the globe. The water desalination capacity is also increasing at a steady pace due to the growing demand for freshwater. With increase in water desalination capacity, the demand for desalination equipment is also growing substantially.

Increase in Saltwater Intrusion Globally Surges the Demand for Water Desalination Equipment

Several areas across the globe are largely affected by saltwater intrusion, which can lead to groundwater quality degradation, including drinking water resources. Saltwater intrusion is increasing in many coastal areas due to groundwater pumping from coastal freshwater wells. In some coastal areas, saltwater intrusion is caused naturally due to increase in sea water level and decrease in groundwater level. Increased melting of glaciers due to global warming and ocean thermal expansion are the reasons behind the global sea-level rise. The sea level has risen 21-24 centimeters since 1880, and in 2020, global sea level set a new record high of 91.3 mm.

Saltwater intrusion can't be stopped as there is a continuous increase in greenhouse emissions globally, but it can be minimized. Over the long run, there should be a feasible solution to fulfill the demand for freshwater as saltwater intrusion is taking place to a great extent. Desalination is one of the convenient solutions to fill the freshwater white space.  


Growing Environmental Impact due to Desalination Plant Operation Hampering the Demand for Water Desalination Equipment

Most desalination forms use a lot of energy to process freshwater. Most fossil fuel-based sources fulfill the energy requirement, which amplifies climate change and increases greenhouse gas emissions. Marine life is largely affected due to huge utilization of seawater intake for desalination. Larvae, mature fish, and other sea creatures die when sucked or trapped into the intake pipes. According to the estimate of the State Water Resources Control Board, California, on an annual basis, about 70 billion marine life and fish larvae are killed by California's coastal power plants.

To produce one gallon of freshwater, approximately two gallons of ocean water are required, and a single desalination facility can't fulfill the need for a region's freshwater supply. There will be more desalination plants and more chances of greenhouse gas emissions and threats to marine life. Unless and until there are convenient energy solutions to run desalination plants, there will be continuous emissions of greenhouse gasses. To overcome the impact of desalination on the environment, several initiatives such as recycled water expansion, stormwater capture and reuse, water conservation, and so on have been taken, which, in turn, decrease the number of year-on-year growth in desalination plant count, thereby hampering the market growth.
