Preliminary upgrades at the Willis Street Pump Station are nearing completion.
A number of minor works have already been finished as part of TasWater's contribution to the Tamary Estuary River Health Action Plan.
“This program of works, once complete, will help improve water quality within the Tamar and represents TasWater’s component of the overarching RHAP,” TasWater Capital Delivery Office Group Leader Planning and Investigation Andrew Truscott said.
Two further engineering packages will be issued for tender this month including the Margaret Street Sewerage Pump Station upgrades and the Margaret Street major sewer pipe diversion.
A consultant will be hired next month to help with the Tamar Estuary combined system upgrades.
“A number of local Tasmanian consultants have also been engaged to undertake flora and fauna, geotechnical, Aboriginal and European heritage surveys,” Mr Truscott said.
“These works will inform environmental approvals and the final design process.”
Construction work on the major projects are scheduled to commence towards the end of 2021.
