Beechworth Sewer Project Background

• The

The Problem? Infiltration results in sewer overflow and spill into Beechworth Historic Park.

• Wh

What are we doing? g? Increasing capacity of the sewer system to address environmental risks and provide for growth of the town.

• How?

w? › Increasing the size of the sewer main (pipeline) that transfers sewage to the WWTP; and › Upgrading the WWTP to treat the increased flows and load.

Pipeline

Pipeline background

• Beechworth’s sewer main runs through the Historic

Park (constructed 1967)

• Heavy rain events in 2016 led to a number of sewer

spills at the Church Street inlet

• EPA issued a Pollution Abatement Notice to North

East Water, requiring capital works solution

• Two preliminary options were identified – a large tank

at top of the Park or a new, larger pipeline

• North East Water commenced discussions with

stakeholders in late 2016

What have we done since we last met?

Since March 2018, we have:

• Consulted with regulatory stakeholders – Indigo Shire Council, DELWP

, Parks Vic, EPA

• Completed preliminary designs
• Gained Board endorsement for final alignment
• Engaged external consultant to provide detailed design of pump station and pipeline
• Internal review of detailed design
• Commenced discussions with WWTP neighbours

10 10

Detailed Design

• Difficulties overlaying an aerial photograph on to a flat map – pipeline alignment on crown land not

not private property

• Churc

rch Stre reet – new pump station within existing site, open trench

• Last Street – open trench and backfill along road reserve
• Sydne

dney y Road – under bore

• Old Chilt

ltern n Road: › Under bore › Follow utilities corridor and power lines

• Pine Trac

ack: › Under bore › Follow Parks Vic Management track › Avoid sharp bends

11 11

Next Steps

• Liaise with approval authorities (EPA, DELWP

, Parks Vic, Council)

• Submit Planning Permit to Council
• Construction of Church St pump station February

2020

• Commence pipeline construction mid 2020
• Continue to inform the community and residents as

project progresses

Wastewater Treatment Plant Upgrade

Background

• Built in 1960s
• Located on McFeeters Road, 3.5km north-

west of Beechworth

• Consists of 3-step treatment process:

– primary anaerobic treatment lagoon – series of secondary lagoons – Final polishing prior to discharge

15 15

Purpose of Upgrade

• Increase capacity:

– Additional flows due to new sewer main capturing stormwater infiltration – Accommodate town growth

• Reduce risk of odours
• Minimise noise
• Maximise effluent reuse

16 16

Upgrade design process

• Design addresses environmental and growth needs of community
• Informed by regular meetings and discussions with neighbours for past 12 months
• 2 independent consultant peer reviews of design
• Will include:

– New inlet structure – New treatment process – new lagoons and aerators – Wet weather buffering

17 17

18 18

Next Steps

• Consultant has been engaged to develop a preliminary design
• EPA Works Approval application November 2019
• Upgrades expected to commence in 2020
• Will continue to meet with neighbours on-site
