Water Sampling
Water samples taken from tanks shall be sent to a SAC-SINGLAS (Singapore Accreditation Council-Singapore Laboratory Accreditation Scheme) accredited laboratory for physical & chemical analysis and bacteriological examinations. Parameters are well within the Guidelines for Drinking-Water Quality set by the World Health Organisation (WHO). A test report from the accredited laboratory will be provided upon satisfactory results.
