Drilling new and refurbishing existing bores remain a priority for Dubbo Regional Council as part of its preparations for "another water crisis".
In the depths of the drought and as Burrendong Dam water levels dropped dramatically, the council set about finding more groundwater with the help of $30 million provided by the state government.
Dubbo, Geurie and Wellington will benefit, with the latter having been dependent on the Macquarie River for water.
The bore work has continued despite dam inflows resulting from rain in the past few months.
On Thursday, the dam was at 20.9 per cent of capacity after falling below 1.5 per cent early this year.
A council spokesman has provided an update on the search for more groundwater and reiterated its importance.
"The new bores identified in the Water for the Future strategy will provide drinking water for their respective communities," he said.
"The urgency of establishing the new bores for drinking water has been alleviated by the rain that has fallen in the catchment in recent months.
"Dubbo Regional Council will proceed with work on the new and existing bores in the event of another water crisis."
The spokesman outlined work underway in the three communities.
"Work will continue at Devils Hole, Dubbo, testing at Bumblegumbie, Dubbo, and refurbishing Martin's Bore, Dubbo," he said.
"Work to replace infrastructure of Montefiores and Bicentennial Park bores in Wellington will also proceed along with two replacement bores in Geurie."
The spokesman said the $30 million would also cover the cost of "pipelines, pumps and electrical" needed to connect the bores in Geurie and Wellington to existing treatment plants.
The Water for the Future strategy also includes construction of Dubbo's cross-city pipeline which has drawn 19 tenders from across Australia.
