Scottsdale Irrigation Scheme project manager Andy Corbould said the workshop would offer potential irrigators a chance to hear from farmers who had bought water allocations in other schemes.

"There will also be consultants talking about on-farm irrigation," he said.

"The idea is to give Scottsdale farmers a chance to ask others about the pros and cons of on-farm irrigation."

Mr Corboult and Tasmanian Irrigation staff on Tuesday followed up last week's water sale launch at Scottsdale with a presence at Scottsdale's LINK Centre.

Tasmanian Irrigation staff will be at the Scottsdale LINK every Tuesday until water sales close on Wednesday, November 26, and at other times by appointment.

The team will also be at the Scottsdale Show on November 14 and 15.

"We were kept busy all day with inquiries about the scheme, the cost of water and the area it would cover," a delighted Mr Corboult said.

"It's unusual to get so much interest so soon after the launch."

Tasmanian Irrigation hopes to secure commitment for 6450 megalitres of water in the scheme by the November 26 sale closure date.

Mr Corboult said that this represented about 75 per cent of the scheme's proposed 8600-megalitre capacity .

"Farmers have been waiting 15 years for this, and I am confident they will more than meet the target," he said.

"Back in 2011, we had expressions of interest for 11,650ML from 90 farmers, so the demand is definitely there."

The state government last month approved the business case for the Scottsdale scheme, which requires $12 million of private investment in order to attract $34 million from the state and federal governments.

The Scottsdale water will cost $1400 a megalitre, with 10 megalitres being the minimum allocation.

Entitlements include an irrigation right, a zone flow delivery right and a connection agreement.

It is understood that outside investors may be able to buy allocations if local landowners do not reach the 6450-megalitre target.

The scheme will use water from the Camden Rivulet, on the Sidling Range, that would be pumped to land that is involved in dairying, livestock, potatoes, poppies and vegetables as far away as Bridport and Waterhouse.

Buyers must complete an application form and pay a 2 per cent deposit for their entitlement before that date.

Construction is scheduled to start next year.
