Agenda
Dungowan Dam wall construction 1954
On behalf of Water Infrastructure NSW
We would like to begin by acknowledging the traditional custodians of the lands on which we
meet today
We pay our respects to elders, past, present and emerging.
Acknowledgment of Country
Background: About the project Project drivers:
Increases in supply allocated to
Tamworth town water
Existing allocations for water
users maintained
New pipeline connecting the new
dam to Calala Water Treatment
Plant
Project Scope:
Project update
• Main line and pressure reducing valve stations design
100% complete
• Major orders placed for HDPE piping and valves
• Field investigations for EIS and Geotech are on hold
during lockdown
• Face-to-face engagement on hold during lockdown –
webinars continue
• All works that can be completed remotely continue
• Progress continues on the Final Business Case

Environmental Impact Statement
What is it?
Environmental Impact Statement The EIS will go on formal exhibition so you, the community, government agencies and the consent
authorities can make informed submissions on the project.
Before then, we want to talk to you about each draft technical report. This is so we can hear your feedback and answer your questions.
We will then consider your feedback and incorporate it where relevant before the EIS goes on public exhibition.
If you still have feedback when at this point, you can make a formal submission
Environmental Impact Statement
Land use
What we assessed
• In addition to general investigations and assessment, six individual impacted
properties were inspected, and the landowners were interviewed.
• The properties were chosen to represent a range of geographical locations,
potential project impacts, and types of agricultural operations.
• Inspections looked at things like agricultural uses, current or potential biosecurity
risks, crop types and locations, soil characteristics and vegetation.

Environmental Impact Statement
Land use
What we found
The impact of the project on agricultural productivity at a regional scale
will be small.
The land use assessment found that impacts to be managed will include:
• Individual landowner needs
• Land productivity
• Temporary or permanent changes on land
• Vehicles and machinery being on land
• Potential impacts on livestock
• Biosecurity hazards
• Rehabilitation of land
Environmental Impact Statement
Land use
How would land impacts be managed?
• Working closely with landowners and businesses to agree and arrange reasonable changes to
cause the least disturbance.
• Use existing roads and tracks
• Be aware and mindful of livestock on or around land
• Close management of biosecurity
• Rehabilitating private land
Environmental Impact Statement
Contamination and soils
What we assessed
The assessment identifies contaminants of
potential concern and affected areas and
where further assessments may be required.
This assessment involved project site
inspections as well as using available
historical and current records, aerial
photographs, topographic maps, and land title
information.
Environmental Impact Statement
Contamination and soilsWhat we found
• Low to medium risk of disturbance of
contamination from historical mine
exploration.
• Low to medium risk of effects from a
former sheep dip site.
• Low risk of naturally occurring asbestos.
• Low risk of naturally occurring potential or
actual acid sulphate soils.
• Low risk of acid rock drainage impacts.
• Very low risk of widespread use of
pesticides/herbicides and
contaminated fill material.
• Very low risk of demolition waste or
contaminated soil
• Very low risk of widespread or
significant asbestos contamination.
Environmental Impact Statement
Contamination and soils
How would contaminations be managed?
• Undertake further assessments to understand the extent of contamination.
• Assign a dedicated Environmental Management Team.
• Appoint an independent environmental auditor.
• Apply strict health, safety and environmental measures.
Measures could include:
• Specialised material storage and transport conditions.
• Materials tracking and records.
• Training and supervision.
• Decontamination processes.
• Management of surface water runoff.
Environmental Impact Statement
Waste
What we assessed
Waste was assessed by identifying:
• How the project will produce waste.
• What kind of waste will be produced.
• What impacts the waste could have.
• How the impacts could be reduced.
• Opportunities to reuse waste.
• Options for disposing of waste.
Our assessments help us predict waste sources, plan ways to reduce or reuse it and assess disposal
options that reduce environmental impacts.
Environmental Impact Statement
Waste
What we found
There will be four main types of waste produced
The project will manage
waste in six main ways.

Waste
How would waste be managed?
In addition to standard waste management strategies, initial investigations have identified ways the
project could reuse materials to reduce waste, including:
• Reusing excavated rock from the spillway in the new embankment.
• Reusing materials from the decommissioned embankment to rehabilitate part of the old reservoir.
• Reusing around 280 tonnes of vegetation toward wildlife habitats.
• Processing and recycling around 13,200 tonnes of vegetation into compost and mulch.
• Reusing water in water trucks to spray areas that could be dusty.
