The outdoor plan is part of the Horsham Rural City Council's 10 year masterplan.

This stage of the pool works involves upgrading the outdoor pool which is over 50 years old and predominantly of the original design.

The upgrade will include a new wet deck to the outdoor pool perimeter and the new pool concourse, including demolition of the existing concourse.

The initiative came into play after concerns were raised by Horsham Swimming Club, regarding the limitations of the previous 50 metres pool not qualifying to attract state level events.

Horsham Aquatic Centre manager Sam Winter said the new upgrade work started in March.

"We are practically putting in a new pool. We are putting in a shell which will change the depths of the pool. It will decrease the shallow end and increase the deeper end," she said.

Ms Winter said the new pool will introduce an access ramp, providing better inclusion for people with disabilities.

She said the community members could use two aquatic wheelchairs provided to access the pool.

"It will allow people with disability and older population who don't feel confident or safe walking the stairs, to walk down the ramp, and access the pool," she said.

Council project manager Madelein Van Heerden said the ongoing upgrade work is estimated to be completed by December.

She said the construction timelines were located along O'Callaghan's Parade and inside the Aquatic Centre for public viewing.

"As work is completed, images will be added to the signs so people can follow the construction and rehabilitation works," she said.

"People are encouraged to look through the fence and watch the works as the project progresses."

As part of the masterplan, amenities like spa and sauna, and new aquatic play space for children will be introduced at a later date.
