Why Sewage Treatment Plants Are Important in Sri Lanka
Sri Lanka faces mounting water pollution challenges due to rapid urban development and industrial growth. With over 21 million people and a thriving tourism industry, the island nation generates substantial amounts of wastewater that requires proper treatment. The discharge of untreated sewage into rivers, lakes, and coastal waters has led to severe environmental degradation, impacting marine ecosystems and public health.
The government has implemented strict environmental regulations requiring industries, hotels, and large residential complexes to install a wastewater treatment plant in Sri Lanka. The Central Environmental Authority (CEA) mandates that all establishments generating more than 25 cubic meters of wastewater per day must have proper treatment facilities.
Tourism, being a major economic driver, has further emphasised the need for sewage treatment solutions Sri Lanka. Hotels and resorts must maintain international environmental standards to attract eco-conscious travellers, making STP installations essential for business sustainability.
