As per the International Labour Organization, retrofitting outdated systems to accommodate advanced chemicals requires substantial investments, with municipalities spending up to EUR 100 billion annually on infrastructure upgrades. These financial and logistical barriers slow the adoption of innovative solutions. Furthermore, the delays in modernizing infrastructure exacerbate water scarcity concerns, particularly in Southern Europe is additionally to hinder the growth rate of the market in the coming years.
Public resistance to chemical usage in water treatment presents another major challenge. According to the European Environment Agency, over 15% of municipal water projects face opposition due to misconceptions about the safety of chemicals like chlorine and alum. As per Eurostat, public campaigns against synthetic additives have led to a 10% decline in their adoption since 2020, despite their proven efficacy. According to the International Labour Organization, misinformation about chemical by-products, such as trihalomethanes, has fueled skepticism is delaying regulatory approvals and project implementations. This lack of awareness complicates efforts to implement effective solutions is hindering progress toward sustainable water management goals across Europe.
