Water pollution is a major environmental concern in Thailand. One of the main reasons is the unmanaged discharge of untreated domestic wastewater directly into water bodies resulting in the deterioration of water sources and significant GHG emissions. A growing population along with urbanization, industrial and agricultural expansion lead to an increased demand for water and wastewater services. At the same time climate change resulting in more frequent floods and droughts exacerbate the management of urban water services.
WaCCliM in Thailand
Recognising the importance of climate change mitigation in the wastewater sector beyond the municipal level, the WaCCliM project is working with the Ministry of Natural Resources and Environment (MNRE) and the Wastewater Management Authority (WMA) to improve the carbon balance of the pilot utility of Chiang Mai.
Three follower utilities in Hat Yai, Sansuk and Krabi municipalities, have started their journey towards climate mitigation in 2017.
The water sector is increasingly being impacted by climate change. It also contributes more than 5 percent of global carbon emissions from its energy consumption, direct emissions of greenhouse gases such as methane and nitrous oxide from wastewater systems, and water heating from end users. Water loss in distribution networks and higher than necessary energy consumption are contributing factors.
