Case Study Thailand // How Chiang Mai’s Wastewater Utility is Building Capacity on Sustainable and Innovative Solutions to reduce its Carbon Footprint.

This case is part of a case study series, where the Water-Energy-Climate Nexus approach supports the transition towards a more sustainable and low-carbon urban management. In the city of Chiang Mai, the WaCCliM project supports the Wastewater Management Authority (WMA) in assessing opportunities to reduce its carbon footprint. A baseline study identified the leaks of untreated wastewater, caused by fractured pipes in the wastewater collection system, as the main source of greenhouse gas (GHG) emissions in Chiang Mai. A large amount of untreated wastewater is flowing directly into the public canal. Because of this, the city is producing significant amounts of methane (CH4) and nitrous oxide (N2O), both gases with a larger global warming potential than carbon dioxide (CO2). The emissions from direct discharge of untreated wastewater account for 579,900 kg CO2 per year in the city. The cooperation between WaCCliM and the WMA in Thailand has raised the local awareness for the challenges in the wastewater sector and the need for improvements in the urban water management in order to achieve resilient water utilities. Therefore, knowledge transfer and capacity building are necessary for long-term success and continuous progress.
