From 2013 to 2023, the production of water collection, treatment, and supply in Greece experienced significant fluctuations. The sector saw a substantial decline from 2014 to 2015, followed by minor variations until a dramatic drop in 2020 due to COVID-19 impacts. A recovery phase began in 2021, but growth stalled, resulting in minor year-on-year declines in 2022 and 2023. In 2023, the value stood at 1.07 Billion Euros. The CAGR over the last five years was -0.5%, indicating a slight downward trend.

Forecasts from 2024 to 2028 predict a steady, albeit slight, decline with a five-year CAGR of -0.55% and a forecasted overall growth rate of -2.7% by 2028. This suggests a continued modest decrease forecasted in production volume.

Future trends to watch for:

The impact of climate change on water resources and the necessity for advanced treatment technologies
Government policies and investment in sustainable water infrastructure
Potential advancements in water recycling and desalination processes
Economic factors and population growth affecting water demand and production capabilities
