THE Tweed shire might not need more or larger dams if water-saving options are explored, according to a councillor.
Katie Milne said the debate on the Byrrill Creek and Clarrie Hall dams was clouding the issue on what was the best option to secure the Tweed's water supply.
Cr Milne said the council should wait until the Integrated Water Cycle Management Strategy was completed and look at more options for water conservation.
"When the council did the future planning in the 70s and 80s and the Byrrill Creek and Clarrie Hall sites were identified, then that might have been appropriate in those days," Cr Milne said.
"But they didn't have the water-saving technology that we do have today."
Cr Milne said dual reticulation needed to be considered.
"The relative cost comparison for dual reticulation it seems to be about the same as building the new dam," she said.
Cr Milne said using wastewater for gardens and toilets would save about 40% of water per household.
She said rainwater tanks were another option.
"We are asking people to put in 5000L tanks but it's their choice. If we offered a subsidy for 10,000L tanks then more people would take it up," she said.
The council stalled on securing the Tweed's water future after a 20-year moratorium was placed on any dam project at Byrrill Creek and an amendment to reinstate the rising of the Clarrie Hall Dam failed.
Although Cr Milne was an opponent of a dam at Byrrill Creek, she did not support the amendment to put raising Clarrie Hall Dam back on the agenda.
