The global water and wastewater treatment market estimated to be valued US $ 19.89 Bn in 2020 and poised to grow at significant CAGR nearly 6.8% over 2021-2027. Due to the increase in the population, urbanization and manufacturing industries in developing and developed regions rising in use of water for various purpose. Additionally, depleting of ground water level, requirement of the new water resources and technological advancement for new innovations and techniques for water treatment for reuse will boosts the growth of the water and wastewater treatment market. However, high charges of investments, lack of trained professional to operate and lack of awareness on appropriate usage of water treatment techniques are the major factors that hinder the growth of the market. The global impact of COVID-19 is expected to stifle investment in the water sector. Due to the high cost of downtime, operational reliability has become even more important. Many significant water users have scaled back or decreased their operations, resulting in lower industrial demand. Water utilities are projected to lose a considerable amount of money due to a drop in demand from large industrial and commercial customers as a result of lockdowns and travel restrictions. According to a survey conducted by the Global Water Leaders Group, COVID-19 will reduce industrial water usage by an average of 27%.
