Funded by the City of Ballarat and the State Government Regional Development Infrastructure Fund, the new pipeline will assist in the on-going irrigation of three sporting grounds.

Morshead Park, Trekardo Park and Western Oval along with the sporting clubs and local residents who use the parks, will gain long-term benefits from the extra water supplied by the pipeline.

City of Ballarat portfolio councillor for growth and development, Craig Fletcher, said the project was an important step in council's commitment to refilling Lake Wendouree.

"We are committed to restoring Lake Wendouree to its former glory and the pipeline is an integral part of this process," Mr Fletcher said.

He added that the project had been fast-tracked and was expected to take three months to complete.

City of Ballarat engineering development team leader Phil Kennedy said although it was a big project, due to the long length of pipe, it was pretty straight forward.

"It will be four kilometres of PVC pipeline which is 225mm in diameter," Mr Kennedy said.

"The route of the underground pipe and pump station will take in Talbot St, Ripon St, Pleasant St, and cross through Leith St and Bell St."

The pump station is capable of pumping between 200 and 400 megalitres of stormwater per year.
