Water debate bogged down
A WATER shortfall of between 1100 to 3000ml/yr on the Tweed by 2036 is anything but moderate, according to Tweed Shire Council (TSC).
A debate between engineers at Tweed Shire Council and environmental management consultancy group GeoLINK is continuing over figures contained in the council's Water Supply Augmentation Options Study (WSAOS).
GeoLINK provided an unsolicited peer review of the study, which the council rejected as inaccurate, hastily prepared and risky.
In response to the council's criticism, Duncan Thomson, a GeoLINK engineer, admitted implementing larger rainwater tanks or dual reticulation would only meet the lower end of the shortfall range, and further measures would be needed.
But he claimed the approach wasn't risky, because a shortfall of up to 3000ml a year was moderate. Council officers disagree.
“Given Tweed has 13,750ml/yr available in total, and currently uses some 10,000ml/yr, the ‘moderate shortfall' represents as much as a 30% reduction of the entire Shire's current water use,” a council spokeswoman said.
The council has also denied GeoLINK's claim it botched future water consumption figures, saying it used future per capita data, rather than historical figures.
