New Measures To Improve Drinking Water Safety
20 December 2000 Media Statement
Health Minister Annette King says enhanced management measures to improve the safety of drinking-water supplies will be introduced over the next five years.
Mrs King said the Cabinet had approved drafting of an amendment to the Health Act to require drinking-water suppliers to monitor the quality of drinking-water and, when problems were detected, to take all practicable steps to remedy them.
"Depending on the size of the populations they serve, suppliers will have up to five years to introduce management measures to improve the safety of their drinking-water. Larger communities will be the first to be required to comply."
Mrs King said the significant public health initiative would include regular monitoring in line with the Drinking-Water Standards of New Zealand 2000, and the use of risk management plans to guide the quality assurance of the supplies.
"While almost 2.65 million people were supplied with water last year that was proven to meet the Drinking-Water Standards for New Zealand, about 478,000 people on community drinking-water supplies received water which had not been tested or which was tested using procedures that do not meet the standards.
"These 478,000, nearly all serviced by minor suppliers servicing fewer than 5000 people, and living in disadvantaged communities, will benefit most from the new legislation, as they face more risk of drinking water contaminated with waterborne disease-causing organisms such as Giardia and Cryptosporidium. About 119,000 cases of infectious intestinal disease are reported each year and a number of outbreaks of disease have been traced directly to contaminated drinking-water."
Mrs King said the enhanced measures recognised that "smaller drinking-water supplies and those in dispersed rural communities, where the major problems lie, will have most difficulty in complying with the new legislation.
"For this reason up to five years lead-in has been provided to give them time to work through the issues. During that period a working party of central and local government officials and supplier representatives will monitor and evaluate the effect of the legislation on local communities. The group will report annually to the Cabinet Social Policy and Health Committee on progress."
Background information
The Health Act 1956: Although the Health Act 1956 is the core statute governing drinking-water supplies, there are also numerous other pieces of legislation concerning drinking-water. These include regulations made under the Act such as the Water Supplies Protection Regulations which apply to water supplies in camping grounds, funeral parlours and hairdressing salons.
The amendment to the Health Act 1956
requires that drinking-water suppliers:
monitor
their supplies and make the information available to the
public
develop risk management plans
take all practicable steps to comply with the Drinking-Water
Standards for New Zealand 2000
audit for
compliance with the above requirements.
The Drinking-Water
Standards for New Zealand 2000 replace the earlier
Drinking-Water Standards for New Zealand 1995 and will take
effect from January 1 next year. The Standards detail how to
assess the quality and safety of drinking-water. They define
drinking-water as water intended to be used for human
consumption, food preparation, utensil washing, oral hygiene
or personal hygiene. They provide criteria applicable to all
drinking-water (except bottled water, which must comply with
the Food Act 1981). The Drinking-Water Standards for New
Zealand 2000:
set out requirements for
compliance with the Standards
facilitate
consistency of application throughout New
Zealand
protect public health while minimising
unnecessary monitoring
specify sampling methods
used to ensure water complies
take into account
advances in knowledge of pathogenic protozoa such as Giardia
and Cryptosporidium
include new material on
maximum acceptable values for cyanobacteria (blue-green
algae)
include six cyanotoxins and sixteen
pesticides not previously included in the old drinking-water
standards
raise the acceptable level of boron
from 0.3 milligrams per litre to 1.4 mg/L.

Terms of reference for working party:
1.
Monitor and evaluate the impact on local communities of the
legislation during the five-year lead-in period; and
annually review the extent to which individual
drinking-water supplies comply with the requirements of the
Health (Drinking-Water Supplies) Amendment Act 2001, taking
into account the timetable for compliance set down in the
Act.
2. For each drinking-water supply that fails to
comply, identify the reasons for non-compliance, and actions
taken to effect compliance.
3. Review the options for
improving the performance of drinking-water supplies in
general, including identifying national benefits and costs,
and those for specific supplies.
4. Consider economic,
environmental, social and cultural, and technological issues
associated with implementation of the drinking-water
legislative framework.
5. Where the need for either
increased operating or capital expenditure is identified in
order to comply with the requirements of the Act, the
working party with the drinking-water supplier is to carry
out a benefit cost analysis incorporating a public health
risk assessment.
6. Make recommendations as to the most
cost-effective course(s) of
action.
