IntroductionThe Integrated Water Cycle Management (IWCM) Strategy is a local water utility’s (LWU’s) resourcing1 strategy for the provision of appropriate, affordable, cost-effective and sustainable urban water services that meet community needs and protect public health and the environment.

A LWU’s IWCM Strategy:

sets the objectives, performance standards and associated performance indicators for the water and sewer business

identifies the needs and issues based on evidence and sound analysis ensures infrastructure matches needs determines the investment priority in consultation with the community and stakeholders identifies the ‘best value 30-year’ IWCM scenario on a social, environmental and financial

(triple bottom line) basis.

The key outcomes of a LWU’s IWCM Strategy are:

30-year total asset management plan (TAMP) 30-year financial plan drought and emergency response contingency plan (DERCP).

A LWU’s IWCM Strategy addresses three elements of the Best-Practice Management of Water Supply and Sewerage Framework2 (IWCM, Water Conservation and Drought Management Plan) and six of the nineteen requirements of the NSW Government’s Best-Practice Management of Water Supply and Sewerage Guidelines, 2007.

The IWCM Strategy and the strategic business plan (SBP) need to be prepared in accordance with this checklist and the SBP checklist respectively.

A LWU’s peak planning documents for its water supply and sewerage businesses are its current IWCM Strategy and its current SBP. The IWCM Strategy and SBP need to be prepared every eight years on a rotation of every four years, as shown in Figure 1. As noted in Figure 2, the final IWCM Strategy needs to include a sound financial plan (topic 17 on page 35) for the adopted 30-year IWCM scenario. A SBP document would then need to be completed four years after completion of the LWU’s IWCM Strategy, as shown in Figure 1. The LWU’s water and sewer development servicing plan (DSP) need to be reviewed and updated following the completion of the IWCM Strategy.

This checklist is essentially a road map and has been prepared to help a LWU and its community:

identify the urban water services issues3 assess the options develop and evaluate IWCM scenarios adopt a sound IWCM scenario, strategy and financial plan in a transparent manner to

address the identified issues.

This checklist and the IWCM Information Sheets are based on and supersede Appendices A, C, D and F of the NSW Government’s Best-Practice Management of Water Supply and Sewerage

1 Refer to page 20 of the Integrated Planning and Reporting Manual for local government in NSW, March 2013 (https://www.olg.nsw.gov.au/sites/default/files/Intergrated-Planning-and-Reporting-Manual-March-2013.pdf ).2 The NSW Government’s Best-Practice Management of Water Supply and Sewerage Framework was introduced in 2004 and updated in 2007, 2011, and 2014 (www.water.nsw.gov.au). The framework, through the 19 requirements, addresses the key recommendations of the Productivity Commission’s Report No. 55 on Australia’s Urban Water Sector, August 2011 (www.pc.gov.au) and the nine National urban water requirements.3 An issue is defined as an unacceptable risk of failure to meet statutory requirements or the adopted levels of service now or within the 30-year planning horizon and needs to be supported by evidence-based data/analysis.

Guidelines, 2007, and has drawn on the IWCM Guidelines for NSW Local Water Utilities, 2004 (www.water.nsw.gov.au).

A current IWCM Strategy is one that has been prepared every eight years and reviewed4 every four years as part of a LWU’s strategic business plan.5

This checklist and the IWCM Information Sheets simplify and clarify the extent of the tasks that need to be completed for an IWCM Strategy, including the issues that need to be addressed for:

levels of service (LOS) regulatory or contractual requirements (Item 1 of Figure 2) the use of ‘approximate typical residential bills (TRBs).

TRBs are suitable for comparing IWCM scenarios, without the expense of undertaking detailed financial modelling for each IWCM scenario.

Furthermore, we have simplified the planning process (as shown in Figure 2) so that once the IWCM Issues Paper (topic 8 on page 21) has been prepared by the LWU and reviewed by the Department of Planning, Industry and Environment, the LWU can proceed to prepare a new IWCM Strategy (topic 15 on page 34). Such a strategy is required every eight years as noted above. This checklist, together with the SBP checklist, is suitable for defining the scope of work6 for engaging a consultant to prepare a 30-year IWCM Strategy.

See the References* section on page 48 for those used in the checklist. It is envisaged that LWU’s would fill in the checklist (Table 1) with support from the department’s Regional Engineers where required. Include the completed checklist in any request for quotation to help consultants fully understand the scope of works and supporting data available from LWU.

As noted on page 1, a LWU’s peak planning documents are its current IWCM Strategy and its current SBP. The section ‘IWCMS and SBP differences’ below summarises the key difference between an IWCM Strategy and SBP.

IWCMS and SBP differencesIWCM Strategy

Based on evidence and sound analysis ensures projects are appropriately resourced any projects and identifies the best-value 30-year IWCM scenario and strategy on a triple bottom line basis (items 13 and 15 on pages 33–34)

Identifies the lowest uniform level of stable typical residential bills (TRBs) to meet the levels of service negotiated with the community and price-path for the next four years in current dollars (Item 17 on page 35)

The adopted 30-year IWCM scenario includes an update of the existing 30-year renewals plan, with only proven evidence-based renewals included for the first five years. The

4 The four-year mid-term review of the IWCM Strategy needs to cover the principal assumptions and risks underpinning the IWCM Strategy, outlined in Items 6.5B to 6.5J on page 9 of the Strategic Business Planning (SBP) checklist.5 In accordance with page 19 of the Integrated Planning and Reporting Manual for local government in NSW 2013, water supply and

sewerage strategic business plans or IWCM Strategies prepared by a county council must also give due regard to the community strategic plans of the constituent councils and must be developed in consultation with the constituent councils. In addition, Clause 219 (2) of the Local Government (General) Regulation 2005 indicates:

‘Following an ordinary election of councillors of the constituent councils of a county council, the county council must review the business activity strategic plan before 30 June following the election. The council may endorse the existing plan, endorse amendments to the existing plan or develop and endorse a new business activity strategic plan, as appropriate to ensure that the council has a business activity strategic plan covering at least the next 10 years.’

The water supply and/or sewerage county council’s business activity strategic plan with respect to Clause 219 (2) are its current IWCM Strategy or current SBP, whichever is the more recent.6 The LWU, in consultation with the department’s regional water utilities representative, needs to review the applicability of each item in this checklist to their LWU’s context before requesting quotes from consultants as the checklist items define the scope of the work. In addition, the LWU may elect to undertake specified items in the checklist in-house.

renewals plan takes account of any avoided, re-sized, abandoned and re-prioritised works (item 11 on page 31)

An IWCM Strategy is prepared every eight years (Figure 1 on page 4) Department concurrence is needed for the IWCM Issues Paper (item 8 on page 21), final

IWCM Strategy and scenario and the financial plan (items 15 and 17 on pages 34–35) before LWU implementation of the scenario

The key outcomes of an IWCM Strategy are the 30-year total asset management plan (TAMP7), supporting financial plan8 and drought and emergency response contingency plan (DERCP9) (Item 17 on page 34)

SBP Reviews and updates the LWU’s existing 30-year TAMP, identifies any opportunities to

downsize or defer significant projects and includes a financial plan Analyses the renewals component of the TAMP to develop a sound 30-year renewals

plan, the first five years of which include only proven, evidence-based renewals that provide value for money

Identifies the lowest uniform level of stable TRBs to meet the levels of service negotiated with the community and the price path for the next four years in current dollars

A SBP is prepared every eight years, that is four years after preparing the IWCM Strategy (Figure 1 below)

Final SBP and financial plan is submitted to the department for registration

The IWCM Strategy and SBP need to be prepared every eight years on a rotation of every four years, as shown below. This involves preparing a TAMP and financial plan every four years, updating these plans annually, and including any necessary corrective action in your annual Action Plan to council.

7 The total asset management plan includes the new infrastructure required for growth and to meet service objectives, renewals infrastructure to meet service objectives, non-build solutions such as efficiency measures and resourcing requirements to meet service objectives.8 The financial plan establishes the total revenue requirements, the borrowings that may be required and the lowest uniform level of stable price path to support the asset management plan.9 The drought and emergency response contingency plan sets out the tactical response measures to ensure the continuity of the water and sewer services under all emergencies that may be encountered by the LWU.

12 Note that the key results for each LWU are reported in Tables 5 to 18 of the annual NSW Benchmarking Report (www.water.nsw.gov.au). From August 2014, a Water Supply and Sewerage Planning Data Set of the key results in these tables for each LWU since and including 2002/03 will be made available from the department. This will provide the bulk of the required data on a ‘whole LWU basis’ and will need to be supplemented with about two to five years of data compiled by the utility on a ‘scheme basis’. However, it should be noted that collecting and maintaining data/information on your system and its performance is mandatory, immaterial of the LWU size to comply with the State Records Act 1998 and for future planning and operational improvements. It is noted that a proposed Best-Practice Information Sheet will provide guidance on undertaking planning using the performance indicators reported in References 16 and 18 on page 21, rather than the traditional indicators such as ‘tenement’, ‘occupied tenement’ and ‘lot’.The IWCM Strategy and SBP need to be prepared every eight years on a rotation of every four years, as shown in Figure 1 on page 3. This involves preparing a TAMP and financial plan every four years, updating these plans annually, and including any necessary corrective action in your annual Action Plan to Council (page 3).

Topic Outcome Achieved In Scope? If no, why not? Supporting data

17. A. A sound financial plan and report in accordance with items 10 to 20 on pages 13 to 15 of the SBP checklist for your LWU’s adopted IWCM Scenario.



30 A separate water conservation plan with the department’s concurrence will not be needed in the future, provided all available water conservation and water cycle management measures and programs have been evaluated within the IWCM Strategy and a suitable water conservation and management program adopted as part of the adopted IWCM Scenario. The implementation of the program and its effectiveness should be monitored and reported within the SBP (refer to items 6.4D to 6.4L on pages 8 and 9 of the Strategic Business Planning Checklist).

31 Refer to the Bureau of Meteorology for definition relating to dry, wet and average years (www.bom.gov.au).32 A LWU must develop a 30-year renewals plan for its existing assets, but only ‘proven’ renewals should be included in the first 5 years of the TAMP. These should be based on documented

evidence and ‘value for money’ (triple bottom line) analysis, which should be reported in an appendix to the IWCM Strategy. The evidence basis and ‘value for money’ analysis should be supported by information collected from preventative maintenance monitoring programs, performance monitoring data, your complaints register, site audits, etc., together with levels of service compliance data and business risks and costs.

While it is important to renew existing assets when they have demonstrably exceeded their economic service life, prematurely replacing assets such as water mains, simply because they are over 80 years old would be wasteful ‘gold plating’, which would unnecessarily increase your TRBs.

33 The approximate TRB established using the normal financial planning process is expected to be within about 10% of the figure calculated in your Financial Plan and Report for the adopted IWCM Scenario (Item 17A on page 38).

34 Such a scenario will provide the best-value for money on the basis of social, environmental and economic considerations. Give the department your LWU’s adopted 30-year IWCM scenario

including the meeting minutes, TAMP and financial plan.

Comment: Any LWU undertaking significant capital works projects needs a robust total asset management plan (TAMP) to ensure its projects are ‘right sized’ and its TAMP provides value for money

on the basis of social, environmental and economic considerations. Refer also to item 1 on page 2.

Sound planning for urban water security requires analysis of climate variability in accordance with the draft guidelines (reference 17) and development of suitable adaption measures as part of the

LWU’s 30-year IWCM strategy.

C. The implementation of your LWU’s IWCM strategy and financial plan is monitored through your LWU’s annual action plan to council where it is mandatory to report the actual annual TRB against the projection in your financial plan, along with the reasons for variance and any warranted corrective actions (refer to Appendix G of Reference 1). This action would effectively ‘close the planning loop’ with your IWCM Strategy and financial plan.

☐ Yes

☐ No



D. The adopted LOS is also monitored by your LWU through the Annual triple bottom line performance report and annual action plan to council which needs to include your LWU’s corrective actions to meet the LOS targets.

☐ Yes

☐ No






E. Note that the adopted IWCM Scenario will continue to undergo the normal refinement during the project implementation stages as concept and detailed designs are developed for key components in response to environmental assessment, local geology, land matters, design and constructability considerations. Experience suggests that such refinement rarely alters the relative ranking35 of IWCM scenarios developed on the basis of sound planning principles. Furthermore, the four-year mid-term review of the IWCM Strategy as part of your SBP preparation will provide a valuable cross-check of the validity/currency of the underpinning assumptions.

☐ Yes

☐ No



19.

Publication of IWCM Strategy and financial plan

A. LWU should publish the final IWCM Strategy, financial plan, TAMP and DERCP on its website, including the key projects in the TAMP.

☐ Yes

☐ No



35 However, projects need to be considered on a case-by-case basis. For instance, if there is a large increase in the capital cost of a project (e.g., a 25% increase, it may be warranted to re-examine the next best IWCM Scenario in order to assess whether it may provide better value for money (on a triple bottom line basis). However, an increase of approximately 10% would not warrant such a re-examination as it is covered by the contingency amount adopted for preliminary cost estimates, which need to be prepared prior to determining the detailed site conditions, project designs, the detailed survey and positioning of structures.
