Project Completion: Stormwater Trash Trap for Northern Beaches Council

TOBCO is excited to announce the completion of an important local project in Newport, NSW for Northern Beaches Council. This involved the installation of a new Stormwater Trash Trap, as part of the Civil Infrastructure Works Panel.

The project comprised construction a new trash trap to better manage stormwater debris at the base of McMahons Creek, which currently flows through the Crown of Newport Reserve.

The new trash rack system will allow for more efficient future servicing of debris with an offline driveway system to access the site, which decreases the frequency of future maintenance visits for Council, and reduces the likelihood of blockage and subsequent localised flooding to the local reserve, and houses.

The scope of works included partial demolition of the existing trash rack structure, sandstone walls, fences and existing trees, installation of a new trash rack structure including concrete, fabricated hot-dipped galvanised structural steel inclusive of exclusion bars, letter box grates, debris control accessible fencing, bollards, erection of 2m high sandstone walls, and construction of a new 2m x 2m stormwater gulley pit over an existing 1350mm Stormwater Main. Additionally, the scope included landscaping of the immediate area and reserve involving reconfiguration of a grass swale, returfing 1300m2 of the reserve, tree transplantation, planting of almost 3000 shrubs and trees and new formalised access pathway for council maintenance vehicles. Re-grading of the creek entrance approach to the trash rack with rip rap as scour protection.

The new trash rack improves the amenities for the creek, local residents who utilise the reserve for leisure, reduce risk of flood for immediately surrounding properties and improves maintenance of the stormwater infrastructure.

Considering the difficult access requirements of the project location, through a winding 2.5m wide access track from Howell Close, Newport, TOBCO utilised the full capability of our unique and diverse fleet of plant and machinery. Both of our Crane Trucks and posi track machines were utilised in combination to transport and off-load approximately 170 large sandstone blocks direct from the quarry to facilitate the sandstone wall construction.
