Kaniva

Kaniva is the largest town in Victoria which does not have a drinking water supply. Upgrading the town’s supply is an investment in the town now and for generations to come. Construction of a new facility has started in preparation for the introduction of drinking water. The new facility will firstly provide improved pressure to the Industrial Estate and extend to the rest of the town when drinking water is introduced.

The Storage Manager has started a review of the Storage Management Rules for the for the Wimmera-Glenelg headworks system. The rules form the basis for how the system is operated day-to-day to support water security for the region.

The review aims to improve and refine the current Storage Management Rules and operation of the Wimmera-Glenelg system, taking into consideration any new data, information and operational experience, to better meet the needs of entitlement holders and improve efficiency. This could include both the storage and delivery of water.

Headworks refers to 10 Grampians reservoirs, the channels and waterways which connect them, as well as the infrastructure and equipment that controls water flow.

The Department for Environment, Land, Water & Planning (DELWP) and entitlement holders can trigger a review, which is required periodically. The current review was initiated in October 2018.

The review focuses on the daily management of the headworks system to optimise water security in the Wimmera-Glenelg system. It is not about changing water entitlements or water allocations or how water is shared within those entitlements.

The review is expected to be completed by early 2021.
