Murrumbidgee IVT

Operations update
Delivery of Murrumbidgee IVT to Commence in December
WaterNSW ABN 21 147 934 787

19 November 2020

WaterNSW is advising customers that delivery of water from the Murrumbidgee Inter Valley Trade
(IVT) account is now scheduled to commence at Balranald from first week of December 2020.
The Murray-Darling Basin Authority (MDBA) has requested that WaterNSW deliver a volume of up to
30 GL in the month of December. The Murrumbidgee IVT account has a current balance of about
102 GL.
WaterNSW is targeting a daily clearance rate of approximately 1,000 ML/day in December. The IVT
is a volume delivered in excess of the end of system flow requirement, which is about 254 ML/day
meaning the flow at Balranald will be around 1,300 ML/day while IVT delivery is occurring.
The IVT account will be adjusted based on the accumulated daily delivery volume, and the
account updated at 9 am each day as per the standard procedure. Allocation assignment
(temporary trade) out of the Murrumbidgee valley would reopen once the account reaches 85 GL.
The process for how the account is managed, including triggers for open and close of trade, can
be found at WaterNSW website.
MDBA may call IVT delivery to continue beyond end of December into the summer. WaterNSW will
provide advice to customers regarding additional call on IVT water delivery when requests are
made by MDBA.
