Hunter Water announced Monday that it had begun construction on a 100-metre sand container sea wall to protect its site at Stockton from coastal erosion.
More than 10,000 tonnes of sand will be excavated and installed in 17 Mega Geotextile Sand Containers along the face of the site.
Hunter Water’s chief investment officer Darren Cleary said the seawall would help protect the land in the medium term.
“The seawall is designed to be a medium term solution for the site. It’s expected to last between five and seven years, while a long term strategy for coastal erosion is developed by the NSW Government and Newcastle City Council,” Mr Cleary said.
The construction, which has been undertaken by a specialist contractor, is expected to take around 12 weeks to complete during which time beach access will be restricted, Mr Cleary said.
In January 2018, a storm event caused significant erosion of Hunter Water’s land and exposed part of a former landfill, which was operated by Newcastle City Council between June 1964 and December 1971.
Hunter Water funded around $3 million to clean up the site, and has estimated funding a further $2.24 million for construction of the sea wall.
