The establishment of Siriraj Hospital has transformed the area into a hub for interdisciplinary medical studies and quality medical services. It has also generated substantial income for traders in surrounding communities, especially the community of Wang Lang. Despite the constant additional expansion, public interest has always been taken into consideration, as evidenced the construction of, for example, Chaloem Phrakiat Park, waterfront walkways and piers. To protect community environment, wastewater from the hospital is subjected to standardized treatment before being drained into Chao Phraya River. Moreover, wastewater testing service is provided to neighbouring communities in an effort to ensure their well-being and safeguard the environment.
