Maintenance and Operating Implications
We intend to retain the ownership of all public water supply
assets on behalf of the communities that these facilities serve.
Asset management, basic design work, contract documentation,
tendering, record keeping, operation and routine repair and
maintenance are to be carried out by our staff. Larger budget
capital works are likely to be let as contracts. Larger repairs,
work across state highways or arterial roads and some
emergency works may also be contracted to preferred or
available contractors. External consultants will be engaged only
for specialised tasks, where we do not have those skills in-house.
Information relating to the overall condition and performance of
the assets that make up the water supply networks in the district
are in our Asset Management Plans. Age and condition have an
influence on the maintenance of assets, but do not necessarily
impact on output and/or outcome performance. Breakages can
occur due to nearby earthworks, natural emergency events,
pressure waves (from pumps) or illegal connections that can
influence demand for water. Low performance can also arise
from an increase in demand from high growth, changes in
technology and materials, and changing expectations from the
community. The Water Asset Management Plan will be reviewed
and updated through 2013.
The Demand Management Strategy will look at significant
ways to improve forecasting, planning and upgrading of water
infrastructure into the future, thus addressing the national issue
of increasing competition for access to water. The challenges
of future growth, development and land-use changes (both
domestic and industrial) within the district and the subsequent
need to replace or renew supply infrastructure to meet these
needs, will drive us to reassess how we currently do our business
and to start thinking smarter and wiser. Water supply efficiency
is a core directive to ensuring that we use what we currently
have more effectively, before expensive upgrade works are
considered. We have a responsibility to help educate the public

to reduce water consumption and encourage other methods
to conserve water (such as grey water systems in new homes).
Most of the network reticulation is in good repair and operating
under a policy of renewal when necessary, thus reticulation should
remain serviceable indefinitely. Pumps, controls, telemetry (data
sent back to the office by radio) and water treatment devices
are repaired as the need arises and are replaced as the benefits
of repair are outweighed by replacement – usually every 12 – 20
years. Reservoirs, weirs, bores, and ponds are maintained on an
on-going basis. The asset ages of on-demand water networks is
quite recent, with the earliest network installations dating back
to 1955 (in Amberley).
Assumptions and Risks
Upgrading of water systems, new treatment plants and filtration
systems to meet Drinking-Water Standards New Zealand, have
all assumed financial subsidies from Central Government in
the past in order for the work to affordably proceed. However,
reduced national subsidy funding (less money available for all)
and the ever-increasing limiting eligibility criteria (specifically
the deprivation index to address more financially needy
communities) have put council in a position that requires
reconsideration of this hopeful approach. We will have to
fund the full cost from their perceived deep pockets, placing
more financial burden upon our communities to meet these
legislatively imposed standards.
