Test water quality from the tap

Testing is done to comply with Philippine National Standards for Drinking Water (PNSDW) as mandated by the Sanitation Code.

Certificate of potability is issued based on PNSDW as required by the Sanitation Code

Traditional approach

Notification comes too late E.g Walkerton, Canada, 7 dead and 2,500 ill (Year 2000)

Water was being tested for bacteriological, physico-chemical parameters; fake results on contamination

Test results - too late to respond

Jailed 2 staff of water utility for “common nuisance”

Testing/standards are narrow E.g. Milwaukee, USA, 400,000 ill of Cryptosporidiosis with

104 deaths (1993)

Water complied with US standards

No testing/standards for Cryptosporidium (chlorine-resistant parasite)

Problems with the traditional approach

• Why testing from the tap is not enough?

• Reactive – problem has already occurred

• Sampling takes time for some parameters

• Response delayed if found positive

Water becomes contaminated

Water consumedWater tested

Test results

Not only relying on water quality from the tap as basis for interventions

More emphasis on monitoring control measures at different parts of the water systems (source, treatment, storage, pipelines)

Water quality from the tap is used to verify if the water system is working

WHO GDWQ 3rd Edition - New approach on drinking water safety

A new approach: Water Safety Plan

- a management tool

- uses a comprehensive risk assessment and risk management approach encompassing all steps in water supply

- from water source to consumer (household).

Risk management approach to water quality management thru water safety planning

WaterSource

Risk assessment: Formation of water safety plan team, system

description, identification of hazards, assessment of risks,

evaluation of existing control measures

Risk management: Improvement of control measures,

Operational Monitoring, Preparation of SOPs, Verification,

Support Programs, Review and revision of Water Safety Plan

Remove or eliminate the risks

Reduce the risks to a tolerable level

Can improve day-to-day risk management

Can develop skills and capacities of water supply service providers

Can improve cooperation and coordination with experts and stakeholders

Can reduce a fraction of the burden of diseases related to poor water quality

Can influence sanitation behavior change
