Request for Information: Chemical Treatment of Sewers

⁠⁠⁠Western Water wishes to undertake an internal review of chemicals used for the management of tree roots in sewers, to establish whether these chemicals are viable for Western Water, considering Western Water's downstream recycled water plants, recycled water users, and biosolids.

Interested Contractors are requested to review the attached spreadsheet and populate it for the chemicals that you deploy for chemical treatment for the management of tree roots in the sewerage system.

This information is being used to assess the use of this chemical in Western Water's system, but in no way suggests that any chemical will be used in Western Water's system.
