1. Background information 2. Department of Primary Industries (DPI) Water and

• ur programs

3. Historical and recent issues affecting water security 4. The Future

Background

• 92 Local Water Utilities

(LWUs) in Regional NSW

• Providing Water &

Wastewater Services to 1.83 million people

• Water and Sewerage asset

replacement cost is approximately $26 billion

Background

Infrastructure in regional NSW

• 350 water supply systems
• 306 water treatment works
• 395 sewerage treatment works
• 3,900 sewer pump stations
• 116 dams/weirs
• 38,000 + km water mains
• 19,000 + km sewer mains

Background

LWUs are required to

• Plan
• Price
• Construct
• Manage
• Operate and maintain

their water supply & sewerage systems

DPI Water

Department of Primary Industries Water

• DPI Water is responsible for surface and groundwater

management and planning to ensure water security for NSW,

• DPI Water ensures the available surface and ground water

resources are shared equitably, and that water entitlements and allocations are secure and tradable.

• DPI Water is responsible for the management of NSW’s water

resources which is achieved through planning, policy and regulation.

• Best-Practice Management Framework
• Regulation under the Local Government Act of 1993

DPI Water

Department of Primary Industries Water

• Short-term and Long-term Water Security Improvement

Projects for Regional Communities

• Improve Water Quality and Supply to Regional Communities

through

• Technical advice and assistance to regional Local Water

Utilities in order to deliver appropriate, affordable, cost- effective & sustainable water supply and sewerage services

• Country Towns Water Supply and Sewerage (CTWSS)

Program

• Regional Water & Wastewater Backlog (RWWB) Program

Programs

Country Towns Water Supply & Sewerage Program (CTWSSP)

• Between 1996 and 2016, the

NSW Government provided approximately $1.23 billion in funding for regional water & wastewater infrastructure

• Up to 50 % subsidy for projects
• More than 450 projects

delivered in 20 years

• This program ends on 30 June

2017

Effectiveness of the CTWSS program & BPM Framework

• The Country Town Water Supply & Sewerage (CTWSS) program has been

highly effective in servicing regional NSW communities.

• The program together with the NSW Government’s Best-Practice

Management Framework (BPM) has delivered key outcomes: – coverage for water supply - 98.0%, 1.81 million population. – coverage for sewerage – 95.6% (increased from 92.3% in 1996), 1.69 million population. – achieved efficient water use and limited the real increase in the water supply Typical Residential Bill (TRB) to 12% over the last 18 years.

Programs

Regional Water & Wastewater Backlog Program (RWWBP)

• This is a new capital works program

announced in October 2016

• $110 million committed to clear “backlog” of

projects in country towns

• 32 Backlog projects have been approved

Challenges

The challenges we have are:

• Ensuring that our water drinking quality remains at a high

standard,

• Capacity to meet water demand for growing populations,
• Drought security,
• Dam safety
• Wastewater treatment.
• Ageing assets
• Skills in regional areas

Long-term Water Security Improvement Projects for Regional Communities

Key threats to water security

• Climate variability / drought
• Growth in demand due to increase in population, industry
• Environmental flow requirements

Possible Projects

• Additional infrastructure such as new dams, enlargement of existing dams,

bores, desalination plants

• Additional infrastructure to link major bulk water dams to major regional

towns and piping of inefficient channels

Direct Outcome/Benefits Achieved

• Maintain continuity of water supply to regional towns
• Enhance regional development and decentralisation

Improve Water Quality to Regional Communities

Key threats to water quality

• Addressing of risks outlined in the national drinking water guidelines
• Protect waterways & quality of life with modern standards
• Potential blue-green algal blooms and associated toxins

Possible Projects

• Provision of reticulated water supply & sewerage to high risk towns
• Additional infrastructure to manage risk to drinking water quality
• Modern critical infrastructure assets for remote communities & LWU’s

facing financial hardship Direct Outcome/Benefits Achieved

• Protection of public health
• Minimised environmental risk

Infrastructure Planning and Delivery

Typical Project Cycle:

• Feasibility investigations,
• Consultation,
• Environmental studies,
• Yield modelling,
• Integrated Water Cycle

Management,

• Financial modelling,
• Funds identification,
• Project management
• Concept design
• Environmental assessment,
• Detailed design,
• Tendering phase,
• Construction
• Commissioning,
• Post completion….

Typical timeframes for small infrastructure projects can be between 2-5 years. Most major infrastructure projects can take up to 10 years from conception to completion

• Water is a finite resource with extensive competing

demands

• Robust strategic planning is vital
• Collaboration, not just consultation, is required as early

as possible for any proposed project

• The NSW Government recognises the needs in regional

NSW and is here to help

The bottom line………
