Water
quality - perfection at any price?
New Zealand's public health officials will look upon last week's
introduction of the Health (Drinking Water) Amendment Bill as a
great leap forward in the quest for enhanced health safety management
of New Zealand's drinking water.
As objectives go ensuring that our communities have access to adequate
supplies of quality drinking water seems an inherently unassailable
one. That's certainly the view of the officials who expect us to
regard as a good thing the shift in the application of approved
water standards further along the path from voluntarism to compulsion.
A bit like Mom and apple-pie, it's not something that is susceptible
to criticism.
In isolation that might well be the case. As currently written
the Bill seems rational enough. Requiring drinking-water suppliers
to take all practicable steps to provide an adequate supply of standards-compliant
water and introduce public health risk management plans, it's fairly
standard and, on its face anyway, worthy stuff.
The Ministry of Health will like it too for the open door that
it provides for the introduction or revocation of drinking-water
standards, including specifications as to composition, transportation
and aesthetic effects. Officials are also likely to welcome the
Bill's provision of an escalating series of penalties to be introduced
for non-compliance for the simple reason that it will mean they
will get to call more of the shots.
It's here that the first objection to this Bill lies. Wellington-based
bureaucracies are not noted for their grasp on the practicability
of what they demand for the rest of us. There may be nothing wrong
with the principles involved - in the immediate case clean is necessarily
good. However, the trouble lies in the fleeting regard that has
been given to the implications of putting theory into practice.
Significant among these is cost. As many communities around the
country are finding, just the maintenance of existing water infrastructure
is an expensive business. Enhancements of the nature contemplated
by health officials will only be more so, giving rise to some real-world
questions about who is going to pay for it all.
To its credit the Government has anticipated this, providing $136.9
million for two assistance programmes: the laboriously entitled
the Technical Assistance Programme (TAP) and the Capital Assistance
Programme (CAP). These are intended to fund, in the case of the
former, the development of the Public Health Risk Management Plans
that will be required under the Bill and, in the case of the latter,
infrastructure improvements.
To smaller communities with limited fiscal options this might sound
like a good deal. But as the very few suppliers who meet the 2005
Draft Guidelines for drinking-water management will attest, the
cost of coming up to the Ministry's standard will quickly outstrip
the available funding, particularly in light of the fact that government's
largesse will not come in one useful lump, but instead be spread
over 10 years. Even according to the Health Ministry's own best
guess the level of expenditure required for infrastructure improvements
may be as high as $250 million - and that in over just six years.
This leaves something of a fiscal and chronological gap that someone
or something is going to have to fill.
This underscores two other problems, although they are less problems
with the Bill than they are with the policy analysis underlying
it.
The first is the Health Ministry's apparent disregard of the many
other infrastructural demands placed either by circumstance or by
policy on local communities. The funding of local transport infrastructure
is an obvious case in point and one that threatens to overwhelm
local body funding capacity all by itself. Add to this the now untrammelled
power of local government to extend its reach into non-core services
and it's not hard to see a large and growing fiscal hole. It is
no small irony in the case of the Auckland Regional Council that
extra charging for drinking-water is seen as a means of funding
public transportation, rather than necessary improvements to the
city's stormwater system. Peter wants to rob Paul, leaving open
the question what Paul will do when the need to address necessary
improvements to water infrastructure arises.
But in the face of unsafe drinking-water, isn't that all academic
and isn't cost a secondary consideration? Maybe. But the working
assumption upon which the Health Ministry seems to be proceeding
is that current drinking-water supplies are in fact unsafe and,
further, that any cost is justified in remedying the defect.
This is the other weakness in the Ministry's analysis. Although
quick to invoke the spectre of Walkerton, Canada, or Milwaukee,
Wisconsin, where outbreaks of E.coli and cryptosporidiosis claimed
some 100 lives, the Ministry is unable to quantify the actual risk
in the local context. As it notes itself "being potentially
waterborne, does not imply that a high proportion of [notifiable
disease] is actually waterborne." Person to person contact,
or contaminated food account for the majority of New Zealand cases,
a fact that blurs not only the question of causation, but also the
Ministry's intervention rationale.
That said, it would be too much to claim that there isn't a problem,
or risk of a problem, with New Zealand's drinking-water supplies.
Nor could one reasonably assert that improvements to some local
drinking water infrastructure is unnecessary. But 49 cases of (possibly)
waterborne disease at a school camp in 2003, or contamination of
the Masterton town water supply with unspecified consequences, are
insufficient justification for a blanket policy of 'perfection at
any price' such as the Ministry seems to be advancing.
Apologists for the proposed regime will quickly point to the "all
practicable steps" provision of the proposed Bill as the answer
to this concern. But it must be remembered that this qualification
is just that - a qualification. It is not an escape clause. Suppliers
will still have to act and the threshold of what constitutes acceptable
action will inevitably be a high one.
In the end, some improvements are both necessary and desirable.
But they will have to be paid for and many communities - not only
small ones - will either be unable to come up with the cash, or
will simply be forced to make another raid on the pockets of exasperated
home-owners. The Ministry could have taken the approach of 'safety
at reasonable cost', but it hasn't. It has instead remained focused
on the worthy public health aim of high quality drinking-water for
all, but in isolation of the larger questions about how its demands
and the many other demands faced by local communities will be funded.
The resolution of this should have been be a prior step. It is an
essential one if the aim of ensuring enhanced health safety management
of New Zealand's drinking-water is to be achieved in reality rather
than intent.
