After the plan was put on public exhibition in June Orange City Council received four submissions backing the plan and two opposing it.

A staff recommendation to next week's council meeting is for the plan to be approved.

It would mean council would give the golf club $3500 for the work, waive fees of $670, gift the club with three large pipes and assist with the documentation for the project.

It is proposed stormwater would be diverted off Woodward Street into an existing dam which would be progressively expanded to hold more water for the golf club's use.

A submission from the club president John Cook said it contributed between $5 million and $8 million into the Orange economy through attracting players and tourists.

Mr Cook said more water was needed to maintain the area.

"Around the course there are some 12,000 trees and shrubs. It takes a lot of hard work and money to maintain this parkland," he said.

Golf NSW chairman Peter Mitchell said on average a travelling player spent more than $200 a day in the local economy.

Mr Mitchell said similar schemes had been adopted by other golf clubs in NSW.

"It's cost effective and keeps clubs financially healthy by not having to buy water which can be problematic in summer months," he said.

However the scheme was opposed by the Orange and Region Water Security Alliance.

President Cyril Smith said it could lead to a drain on the city's water resources.

"Approving this water diversion to Duntryleague may set a precedent for other worthy organisations (sporting fields and parks) to apply for a similar diversion which could significantly impact on Orange's stormwater harvesting scheme," he said.

Mr Smith said the DA did not explain how much water would be taken, whether the club would pay for it and whether the club needed a water extraction licence.

He said as trees might be removed to allow for the expansion of the dam it was not clear what replacements would be provided. Three councillors questioned approving the plan in June.
