In November 2018, the Pattaya City Council approved 188 million baht for the repair of its six wastewater treatment plants. Installed in 2000, the plants can accommodate 65,000 m3 of wastewater per day. More than a third of plant equipment was found to be 40–50 percent worn out. The system treats waste from a 36 km2 portion of Pattaya, or 68 percent of its urban area. Earlier plans to increase treatment capacity to 135,000 m3 were never implemented and existing plants were allowed to fall into disrepair. Pattaya uses more than 200,000 m3 of water a day, but claims to only discharge about 70,000 m3 a day. The discrepancy is unexplained. Once treated, there are no tests to measure water quality before it is dumped back into the sea, which may account for foul water discharges.
