The Pattaya Water Authority has warned residents to exercise caution and frugality when using tap water as the city’s reservoirs dip below the minimum retention level.
The request was posted on the Facebook page of the Pattaya Provincial Waterworks on Thursday, asking people to use tap water sparsely.
According to the PWA, the combined water available has dropped to 8 million cubic meters, around 20 percent of the total capacity.
Water used in Pattaya comes from five separate reservoirs. The water from the pools is fed into a single water treatment plant before being dispersed around the city.
At present, the supply from the reservoirs is at a minimum capacity for retention to avoid damage to the system, according to PWA Pattaya Chief, Chaithas Eedsaeng.
In response to the water shortage, the authority has reduced the amount of tap water distributed across the city. Rather than the usual 170,000 million cubic meters of water, the PWA will distribute only 150,000 million cubic meters.
The reduction is designed to maintain the minimum water levels in reservoirs and avoid damage to the water system.
Further measures, including supplying water to some households on alternative days, are also in place. However, customers have already complained that they are not receiving water on the correct days.
The PWA is also taking other measures to supply water to Pattaya, including working with the Royal Irrigation Department to channel water from Bang Phra and Nong Pla Lai reservoirs into the city.
The authority has also purchased raw water from the East Water Group to prevent further shortages.
When asked if the situation will improve shortly, Mr. Eedsaeng said that rain is forecast for the second half of this month in the eastern region and could help fill the reservoirs.
However, according to the Meteorological Department, rainfall in the Pattaya region is forecast to be slightly below average in July.
