Giru Full Service Area 2013-2020 Reticulation

The water supply for the Giru township is treated surface water sourced from the Haughton River.  Burdekin Shire Council considers that the source is unprotected. The Haughton River catchment is  approximately 220km² and similarly to the Burdekin catchment, land use is dominated by grazing with  85% coverage and cropping with almost 7%. At times of low flow in the Haughton River, flows are  supplemented with Burdekin River water via the Haughton Main Channel.
Townsville Water draws surface water from the Giru weir to treat at the Cungulla Water Treatment  Plant and provides drinking water to the Giru and Cungulla communities. The Cungulla treatment plant  is operated by Townsville Water under Townsville City Council’s DWQMP.
For the purposes of the DWQMP, the water supply that Burdekin Shire Council uses for the Giru
scheme is treated water from Townsville.
This scheme operates under an agreement with Townsville that includes a commitment to provide  safe water and identifies the typical chlorine levels that are delivered to Burdekin Shire Council  Infrastructure.

Townsville Water sources raw water from the Giru Weir on the Haughton River and provides treatment  at the Cungulla water treatment plant located at the northern end of the township. The Giru weir is  located on the Haughton River approximately 300 metres downstream of the Queensland Rail bridge  at Giru and is owned and operated by SunWater. A supply agreement exists between Townsville  Water and SunWater. The intake pumps for the Giru water treatment plant is located on the  Queensland Rail Bridge. The weir is supplied by runoff from the Haughton River catchment and is  supplemented by Burdekin River water via the SunWater operated Haughton Main Channel.
