4.1 Vision
The vision for this strategy is for the City of Moreland to become a Water
Sensitive City in which Council leads by example and supports community
actions to manage water resources in an environmentally, socially and
financially responsible manner.
4.2 Goals Key goals fall within the
following two themes
Council leading Council supporting
by example community action
» Reduce Council’s total water consumption » To reduce potable water consumption
to the minimum amount required in order to with the community through water saving
maintain Council’s services to the community measures and displacement with fit for
purpose water use
» Displace the use of potable water consumption
with fit for purpose alternate water sources » To reduce stormwater pollution originating
from residential lots
» Reduce the pollution carried by stormwater
originating from within the Moreland
municipality
» Implement and encourage the uptake of
water sensitive urban design across the
City of Moreland
» Advocate for the efficient use of water
resources and implementation of integrated
water cycle management to the community and

wholesalers on behalf of the community
» Reduce potable water consumption, increase
water reuse and recycling and reduce

Implementation PlanMoreland Watermap 2020 | Appendix A – Implementation Plan 33
Overview
The purpose of Appendix A is to define the approach to implementation
of the actions set out in Watermap 2020.
Projects and costs are defined including the project’s contribution towards delivering the targets
and vision for Watermap 2020. The implementation plan will be reviewed annually to ensure the
actions and strategies, and their priority for delivery remain correct. The prioritisation of actions
will be measured against the criteria outlined below.
Timeframe for implementation
The schedule below provides an overview of the timing for implementation of the key actions
and will be updated annually based upon the outcomes from the annual review process.
