Introduction and contextOur water resources and systems are under increasing pressure from population growth and climate change. These dual pressures are reducing water availability, increasing flood risk and degrading wetland environments.

Local governments have a responsibility to manage water systems to meet these challenges in an environmentally responsible way while, at the same time, enhancing the livability and resilience of the City. This approach has been encapsulated in the term “Water Sensitive Cities” (CRC for Water Sensitive Cities, 2018). This concept encompasses water management in all parts of the water cycle as they are closely related and interconnected. A Water Sensitive City considers the following:

• Stormwater quality treatment,

• Reducing scheme and groundwater use,

• Reuse of alternative water sources such as wastewater,

• Protection of waterway health,

• Reducing urban heat, and

• Mitigating flood risk.

In doing this, a Water Sensitive City will also consider the many other objectives a local government has for public open space and infrastructure. In particular, providing useable and beautiful public areas and supporting local biodiversity. The CRC for Water Sensitive Cities has encapsulated this in seven goals which are;

• Ensure Good Water Sensitive Governance,

• Increase Community Capital,

• Improve Productivity and Resource Efficiency,

• Improve Ecological Health,

• Ensure Quality Urban Space,

• Achieve Equity of Essential Services, and

• Promote Adaptive Infrastructure. (CRC for Water Sensitive Cities, 2018).

In 2013 the City of Kwinana adopted a Sustainable Water Management Plan (City of Kwinana, 2013) to outline how the City would move towards becoming a Water Sensitive City.

In that time the City has gained experience in implementing water management projects and best practice has evolved. It is now appropriate to review the plan in light of this experience in order to continue to improve the City’s water management. The actions from the previous plan are listed in Appendix A along with notes explaining the City’s progress towards their implementation.

This review was completed over six months in the first half of 2018. It involved;

1. Collating and analysing the City’s most recent water data.

2. Reviewing current best practice.

3. Assessing the City’s performance against the previous plan.

4. Checking each of the measures originally proposed to determine if they had been completed or were no longer appropriate.

5. Determining new priorities and actions.

Rather than addressing the entire suite of issues addressed by the Water Sensitive Cities framework, issues were prioritised that were most relevant to the City and practical actions selected to address these issues. This was done as part of a review meeting held on 22 March 2018 with staff from across the City’s departments. Further input was sought from relevant staff who were unable to attend.

Why act on sustainable water management? The City has recognised its responsibility to act on sustainable water management. The latest review of the Strategic Community Plan (City of Kwinana, 2017) completed in 2017 includes the following objective.

Objective 3.4 Encourage and exercise best practice water management

The City also participates in the Waterwise Council Program run by the Water Corporation and the Department of Water and Environmental Regulation (Water Corporation, 2018). This program involves an annual re-accreditation process where the City must address a series of Waterwise criteria and report on our water management activities. This program is aligned with the Water Sensitive Cities approach and Councils must report on each of the seven goals. The City has

been accredited as a Waterwise Council under this program and has achieved the higher Gold Waterwise Council status for two years in a row. The criteria for the Waterwise Council program has been incorporated into this plan.

WATER ISSUES IN THE CITY OF KWINANA

When considering the best course of action it is important to assess what the major water issues and priorities for the City are. These are described below.

WATER AVAILABILITY

Rapid population growth and increasing groundwater extraction are depleting the quality and availability of our scheme and groundwater resources. Climate Change is likely to result in further decline in rainfall over the South West of Western Australia. (Department of Water, 2009). Figure 1 below illustrates the rapid reduction in run-off to dams in the south-west over the last 30 years.

The availability of groundwater is similarly declining. Many aquifers are now reaching their licensed abstraction limits and many new subdivisions are refused a new groundwater allocation by the Department of Water (Department of Water, 2009).

This reduction in both scheme and groundwater availability means we will no longer enjoy the easy access to cheap water for our pools, parks and gardens that has been enjoyed in the past. We must adapt and innovate if we are to maintain our community facilities to a level the community expects.

This is particularly relevant to the irrigation of the City’s parks and gardens which rely on groundwater for irrigation. The City also owns a large number of buildings and facilities that use scheme water including the Recquatic and Kwinana Adventure Park. There is the opportunity to reduce water use in these facilities through retrofits and leak detection.

STORMWATER MANAGEMENT

Wetlands and other natural environments are affected when the quality of water flowing into them changes. Water flowing into a wetland may come from stormwater and groundwater from a large surrounding area encompassing suburbs, roads and industry. Anything that falls on the ground in those areas (fertilisers, sediment, heavy metals, oil, petrol, herbicides etc) is transported by the stormwater and, if it is not treated, can end up in groundwater, wetlands, the ocean and in some areas of Kwinana the Peel Main Drain, which feeds the Peel Harvey estuary (Department of Water 2004).

These pollutants can cause a range of problems. For example;.

• Sediment can smother vegetation, transport toxic pollutants and block stormwater infrastructure.

• Fertilisers can build up in water bodies causing algal blooms (Department of Water 2004).

The City has an opportunity to address these problems by installing treatment measures in our existing stormwater infrastructure and by implementing Water Sensitive Urban Design in our new developments. This approach uses urban planning and design to attenuate stormwater high in the landscape, stopping it from picking up pollutants and reaching our waterways (Melbourne Water, 2018).

This can be achieved by reducing the amount of piped stormwater infrastructure and infiltrating and treating rain high in the catchment with swales, raingardens, rainwater tanks, gross pollutant traps, street trees and sediment ponds. It also involves restoring wetland habitats to improve their ability to filter stormwater.

Water Sensitive Urban Design in new developments is informed by Better Urban Water Management (WAPC and Department of Planning and Infrastructure 2008). This document provides guidance on the implementation of State Planning Policy 2.9 Water Resources (Government of WA, 2006). It is also supported by Liveable Neighbourhoods under Objective 6 – Ensure that water is protected and managed to maximise efficiency by incorporation of urban water management techniques into the urban design (Department of Planning, 2015).

LITTER

Litter was identified specifically as a priority water issue. Illegal dumping, litter from building sites and general public place litter all make their way into reserves and wetlands and eventually into local waterways and the ocean. Plastic litter in particular never biodegrades which makes it easier for it to be washed into waterways where animals mistake it for food or become entangled (Australian Marine Conservation Society, 2018). The City has the opportunity to address illegal dumping and building site management through our local laws and compliance as well as adapting stormwater infrastructure to collect litter.

Water consumption dataBaseline data on both water consumption and water quality within the City has been collected and is presented below. This data allows the City to identify the highest priority areas for action.

Figure 2 above indicates the City’s total scheme water consumption over the past seven years. During this time consumption has varied from between 30,000KL to over 45,000KL per annum. Water use varies naturally due to weather conditions, user behavior and leaks. Calculating a trend line (to account for these variables) indicates that consumption has decreased by approximately 15% over this time.

The dip in consumption around 2014/15 and 2015/16 may have been partially due to the Recquatic closing for refurbishment and the increase in 2016/17 due to the re-opening of the Recquatic and the opening of the Kwinana Adventure Park which includes a Splash Pad.

It could be expected that consumption could rise again next year as the Adventure Park only opened part way through the 2016/17 financial year. Water efficiency measures have been implemented but the majority of these took effect in 2015/16 and 2016/17. These measures may have mitigated potential increases over this time. The cost of water has also increased over this time with the City now spending nearly $90,000 on water each year. The cost per KL has increased from $1.33 to $2.18 in that time.

Figure 3 below is per capita scheme water consumption (by City operations) per resident.

Figure 5 above shows this data broken down further into the top 10 consuming accounts. The high consuming sites listed above will be targeted for water conservation measures.

PROGRESS TO DATE

The City has undertaken a range of actions and policies in the area of sustainable water management over the past five years as part of the Sustainable Water Management Plan (2013-2018).

Scheme water efficiency measures include:

• Water monitoring and leak detection – 10 buildings have been fitted with water data loggers and a real time monitoring system has been installed at the Recquatic. These have picked up several large leaks saving approximately 12 million litres of water.

• Public Toilet Retrofit - Inefficient toilets and urinals were replaced at Sloan’s Reserve, Rhodes Park, Medina Oval and Challenger Beach.

• Administration Building and Depot water efficiency retrofit – Water efficient toilets, flow restrictors, sub-meters and low flow showerheads were installed at the Depot and the Administration Building. This saves approximately 900,000 litres of water per year.

• Green Building Policy (new and renovated buildings) - adopted by Council in January 2018. This policy includes water efficiency requirements for new and renovated buildings.

Figure 6 Groundwater abstraction

Figure 6 above displays the City’s groundwater data for the previous 8 years. The trendline indicates that groundwater consumption has decreased by approximately 15% or 90 million litres over that time.

Figure 7 below indicates groundwater consumption per hectare. This demonstrates that despite the City’s growth there has been significant reductions in consumption of over 40% per hectare.

Figure 7 Groundwater abstraction per irrigated hectare

This has been due to work undertaken as part of the City’s Groundwater Strategy (2014-2019). The majority of this work has now been done and it is likely that the rate of improvement in water efficiency may now slow down unless there are further advances in best practice.

Groundwater efficiency measures include:

• Centralised Irrigation Control which allows for detailed water budgeting based on the quality of turf or garden required and seasonal conditions. 63% of the City’s bores are now attached to this central controller.

• Reviewed the Irrigation Development Guidelines (City of Kwinana, 2014) for new developments to ensure irrigation systems which are handed over to the City are water efficient and compatible with the City’s systems.

• Replacement of particularly poorly performing irrigation systems at Calista Oval and the Administration Centre.

Water quality dataA simple and cost effective method for identifying priority water quality actions is to collate a map of water quality “hotspots” in the area. It also allows a visual summary of water quality issues specifically relevant to the City. The information has been taken from the City’s Intramaps database (stormwater infrastructure), Groundwater Operating Strategy (monitoring bores) and Department of Water Spatial Services for the Peel Main Drain and catchment boundary. The map is provided in Figure 8 on the following page.

The map notes the location of the Peel Harvey Catchment Boundary and the Peel Main Drain. The area within the catchment and adjacent to the main drain should be targeted for water quality interventions as they are in the catchment for the Peel Harvey Estuary, an important environment which suffers many water quality issues. Particular care should be taken with development in this area to minimise nutrient export in accordance with State Planning Policy 2.1 Peel Harvey Coastal Plain Catchment (WAPC,2003).

The City’s wetlands are also indicated to demonstrate the role they play in treating stormwater and attenuating floods. These wetlands should be protected and rehabilitated to enhance this function.

The map also identifies pollutant sources such as sites where litter is generated (such as shopping centres, new developments and train stations) and stormwater infrastructure in reserves with no water quality treatment. This identifies several sites where gross pollutant traps or similar litter and sediment attenuation devices should be installed to prevent litter and sediment entering natural environments. Building sites can also be targeted for verge permit compliance campaigns and education.

The City has undertaken a range of actions and policies in the area of water quality over the past five years including;

• Water Sensitive Urban Design at the Kwinana Adventure Park - The Kwinana Adventure Park project included the installation of four raingardens (gardens which filter stormwater).

• Local Planning Policy No 1 Landscape Feature and Tree Retention – this planning policy aims to retain vegetation in new development sites which assists with stormwater attenuation and treatment.

• Builders litter and illegal dumping project - Keep Australia Beautiful funding was sourced to tackle illegal dumping and builders litter in Millar Wellard reserve. This project included the installation of two covert cameras, two litter cleanups, signage and a letter drop to neighbours encouraging them to report littering.

• Participation in Clean Up Australia Day.

• An ongoing program to tackle illegal dumping including covert cameras, restricting access to known hotspots and enforcement.

• Encouraging developers to include Water Sensitive Urban Design in new developments. This has been particularly important in areas with multiple water related constraints in the Peel Harvey Catchment.

• Ongoing restoration of the City’s wetlands through weed control and planting with appropriate endemic species.

Community Education and EngagementThe City can also play a role in educating the community about water conservation and quality issues by delivering education and engagement programs. Existing initiatives include;

• Adopt a Verge Program - This program encourages residents to plant a local native waterwise garden on their verge. This involves free mulch, subsidised local native seedlings through the existing seedling subsidy scheme, a verge gardening tips document, advice and a Verge Gardening Workshop (in 2017 only) where free soil conditioner and soil wetter was handed out to participants.

• Living Smart Sustainable Living Courses – a seven week sustainable living course for residents has been delivered annually for the past 3 years. This course includes modules on home water efficiency and water efficient gardening.

• Switch Your Thinking – The City recently joined Switch Your Thinking, a regional organisation of Councils that delivers sustainability programs to the public. As part of this the City receives public education workshops, access to the Rewards for Residents and Rewards for Businesses program, recognition programs like Switched on Schools and Switched on Businesses, Competitions such as the Young Reinventor of the Year program as well as other grant funded projects.

• Participation in Clean Up Australia Day.

An environmental education strategy will be completed by the City in the 2018/19 financial year. This will incorporate broader sustainability issues, not just water. These existing water education initiatives may be included and expanded on in this strategy.

Water management goalsWithin the Water Sensitive Cities Index further detailed SMART (specific, measurable, achievable, results oriented and timebound) goals are required in some cases.

For the Improve Productivity and Resource Efficiency objective, quantifiable water conservation goals are able to be set. The following water goals were discussed at a meeting held on 22 March 2018 attended by representatives from Engineering, Environment, Assets, Recreational Services and Parks.

The base year of 2016/17 was chosen as the most recent financial year with a full set of data. The target year, 2023, aligns with the expiry of this plan. The percentage reductions were chosen because they were believed to be achievable based on the actions chosen. It should be noted that these goals are intended to be something to strive for and there will be no penalties if the City fails to achieve them.

SCHEME WATER GOAL

To reduce scheme water consumption by 5% on 2016/17 levels by 2023.

To achieve this goal the City would need to save approximately 2,000KL each year. The major actions proposed in this plan which will directly save scheme water are leak detection and retrofits at the Recquatic as part of the Waterwise Aquatic Centre program. The savings from leak detection vary greatly from year to year but based on past experience expanding the current leak detection system alone is likely to achieve this goal.

GROUNDWATER GOAL

Maintain groundwater abstraction at 2016/17 levels until 2023.

The City has been progressively improving water budgeting over several years as well as transferring bores to the centralised controller. This work will be completed over the coming years. The rate of improvement in efficiency of groundwater abstraction is therefore likely to plateau. At the same time the City will take over management of a large number of parks situated in new subdivisions. Climate change will put further pressure on the City to increase irrigation over the summer months. Given all of the above trends this will be an ambitious but achievable goal.

For the following remaining Water Sensitive Cities Index goals it is more difficult to set quantifiable SMART goals;

• Ensure Good Water Sensitive Governance,

• Increase Community Capital,

• Improve Ecological Health,

• Ensure Quality Urban Space,

• Achieve Equity of Essential Services,

• Promote Adaptive Infrastructure. (CRC for Water Sensitive Cities, 2018).

For the above goals this action plan lists a series of actions against each. The objective of this plan is therefore to achieve each of the listed actions.

Implementation planThe actions and priorities in this list may vary as circumstances and technologies change and funding opportunities become available. Actions that relate to the Waterwise Councils accreditation are noted under the relevant action. Each action is identified as new or existing to identify actions that have been carried forward from the previous plan. The actions are categorised according to the Water Sensitive City Index Goals.

Monitoring and reviewThe City’s Sustainable Water Management Plan is intended to be reviewed and adapted to ensure it remains current and relevant. It is intended that this plan be reviewed midway through the plan cycle in the 2020/2021 financial year.

The review process will be coordinated by the Environment Department with input from relevant staff. Ongoing reviews will ensure the plan stays up to date with changes in policy and new technology. This process will also help to review priority areas, monitor progress towards goals and assess the effectiveness of implemented actions. It will also assist in the preparation of annual reports, budgets and the City’s Corporate Business Plan.
