Pattaya Council members inspect new wastewater treatment system on Koh Larn, designed to support growing residents and tourists. PATTAYA, Thailand – At the Koh Larn community, members of the Pattaya City Council  inspected the construction project of the third community wastewater treatment system (Phase 1) at Tha Rai and followed up on the comprehensive waste incinerator project on Koh Larn aimed at solving the island’s waste problem sustainably. The construction of the third community wastewater treatment system (Phase 1) at Tha Na Ban area is necessary because Koh Larn currently has only two treatment ponds located at Ta Waen Beach and Samae Beach, but the Tha Na Ban area, which has a dense residential population, does not have a wastewater treatment pond. Additionally, the natural treatment system currently in use cannot support the increasing number of residents and tourists on Koh Larn. The project is now complete, and the contractor has begun testing the wastewater treatment system. The Tha Na Ban treatment plant can process up to 1,600 cubic meters of wastewater per day. The wastewater treatment process involves sewage passing through a grit chamber, sedimentation tank, balancing tank, biological tank, treatment system, and then into a clean water holding pond. The treated water must have a Biochemical Oxygen Demand (BOD) value of no more than 20 milligrams per liter before it is used for watering plants, street cleaning, and potentially for use with the waste incinerator system in the future. Koh Larn’s third wastewater treatment plant can process 1,600 cubic meters of sewage daily to protect island waters. Regarding the comprehensive waste incinerator project on Koh Larn, the Pattaya City Council members were informed by the contractor that the initial trial to ignite the incinerator and test the heat system will begin on June 26. Once fully operational, the incinerator will be able to destroy both new and accumulated municipal waste on Koh Larn — over 50,000 tons in total — at a rate of 50 tons per day. The machinery will also be capable of sorting 100 tons of waste daily, helping to manage both old and new waste simultaneously to sustainably solve Koh Larn’s waste problem going forward. During long weekends and holiday periods, Koh Larn experiences a significant surge in visitors, with over 20,000 tourists arriving on the island. This sudden increase puts considerable pressure on the island’s infrastructure, especially its waste management and wastewater systems. The new wastewater treatment and waste incineration projects are therefore crucial to sustainably handle the environmental impact caused by these large crowds and to maintain Koh Larn’s natural beauty and cleanliness for both residents and visitors alike. Initial heat tests for Koh Larn’s new waste incinerator begin June 26, aiming to burn 50 tons of waste per day.   Advanced waste sorting and incineration machinery will handle up to 100 tons of trash daily, tackling both old and new waste. Sustainable waste solutions come to Koh Larn as Pattaya City pushes forward with eco-friendly infrastructure projects.
