Hornsby Shire Council – Trashrack Design

Optimal Stormwater was selected to do the design on 2 new trashracks very close to each other at Flametree Reserve at Cherrybrook, removing litter and debris from Nyrippin Creek.
The site was hydraulically challenging in regards to both access, and potential volume of flow coming down the creeks.

A previous solution had been trialled and failed at the site, so to minimise any extra expenditure, they selected a company that had experience with this type of solution.

An offline graduated trashrack was agreed to be appropriate to meet both the removal objectives, hydraulic constraints, and each would provide a solution that was easy for Council to access and maintain.

The devices were constructed by Council, and are apparently working very well.
