The treated water supplied by PPWSA complies with the drinking water standards of the WHO and national drinking water standards. PPWSA tests the quality of the water which has been treated, three times a day at the WTPS and tests 80water samples per week at other points in the networks. Besides, the annual report on water quality of PPWSA issued by the laboratories in Singapore and Shanghai could confirm the quality of the portable water.

Sample of the potable water produced by PPWSA are tested at laboratories in Singapore and Shanghai annually. The data from those laboratories indicates that water produced PPWSA is potable. The number of parameters tested by the two laboratories between 2006 and 2016 is as follows:
•In 2006, 94 parameters
•In 2007, 102 parameters
•In 2008, 209 parameters
•In 2009, 215 parameters
•In 2010, 215 parameters
•In 2011, 213 parameters
•In 2012, 213 parameters
•In 2013, 213 parameters
•In 2014, 213 parameters
•In 2015, 213 parameters
•In 2016, 213 parameters
The analysis of the quality of potable water produced by PPWSA, conducted by the Singapore and Shanghai laboratories is shown in Appendix 6 to this Disclosure Document:

      The maintenance of the water treatment system is conducted by PPWSA's employees, because the outcome in terms of economic and technical efficiency is superior to outsourcing the maintenance function. PPWSA's employees have the requisite skills to conduct the maintenance. In addition, PPWSA has created Standard Operation Procedures for the maintenance of mechanical and electrical systems of the water treatment system. These Standard Operating Procedures were implemented in 2006. Most repairs to the treatment system are made by PPWSA's employees, except those which are beyond their expertise.

The table below shows quality of the water produced by PPWSA in 2016:
