TTW Public Company Limited (TTW) operates the business of production and distribution of tap water to the Provincial Waterworks Authority (PWA) in the vicinity of West Bangkok,
covering the areas of two provinces, namely, Nakhon Pathom Province in three districts, i.e., Amphoe Nakhon Chai Si, Amphoe Sam Phran, and Amphoe Phutthamonthon, and Samut Sakhon Province in two districts, i.e., Amphoe Krathum Baen and Amphoe Mueang Samut Sakhon. TTW has executed the Water Purchase Agreement with the Provincial Waterworks Authority (PWA) for a period of 30 years and TTW was granted a concession for the tap water business operation to use water from the Tha Chin River for producing tap water by the Ministry of Natural Resources and Environment. Moreover, TTW also invested in subsidiaries companies related to tap water management business for PWA, including the acquisition of rights in Industrial Estate.
The modern technology was used by TTW is the Supervisory Control and Data Acquisition (SCADA) which is a computerized system, used for the automatic control of tap water production and distribution process.
As a result, tap water produced by TTW always meets the TIS 257 Parts 1-2521, the standard prescribed by the PWA. In addition, TTW’s tap water supply system has been designed for efficient production with a view to attain a maximum saving on production costs. Said design is based on the “Gravity Flow” principle, in which raw water is pumped up to a water pumping station and then is released to flow downward by gravity through the rapid mixing tank, sedimentation, filtration, and chlorine mixture processes before being sent to the water storage process and, finally, to both water distribution stations. This process allows the Company to save on electricity used in production when compared to pumping water through each of the above steps as is normally done in the tap water production process.
