Tighes Hill - Gross Street Reserve stormwater work

City of Newcastle is working to improve the quality of the stormwater runoff that drains into Throsby Creek and the lower Hunter Estuary. As part of this work, we’re planning to install a gross pollutant trap (GPT) in the road reserve adjacent to 57-59 William Street in Tighes Hill.
 

Construction stages

Construction will be delivered in two stages starting in April/May 2019.

Stage 1 work involves trenching and replacing a portion of the sewer main in preparation for installation of the GPT.

Stage 2 includes installation of the GPT and construction of a new stormwater pit, upgraded pipelines, road resurface, footpaths and kerb and gutter.

These works are scheduled for completion by the end of June 2019, weather permitting. 
 

What to expect during construction

Construction will involve restricting access to a section of William Street between George Street and Rose Street, however through-traffic will be maintained. 

We will aim to minimise disruption and inconvenience to residents, pedestrians and motorists.
 

What is a GPT?

A GPT is a concrete box structure which will be buried in the road reserve and connected to the major drainage line in William Street to help trap sediment and litter from the stormwater before it fl ows into the estuary.
 

Ongoing maintenance

The City will continue to clean and maintain the GPT into the future to ensure optimum performance of the device and improved stormwater quality.
