Wollondilly residents have been urged to share their thoughts on a proposal for water play parks to be built in the shire in future.
The council is considering the feasibility of providing water play facilities to allow for interactive play and cooling down during the warm summer months.
Similar water play parks have been hugely successful in Camden, at Curry Reserve in Elderslie and the new site in Oran Park.
A feasibility report has been prepared, detailing the pros and cons involved in constructing a water play park in the shire.
Wollondilly mayor urged locals to give the report a read and make a submission with their thoughts.
"Water play facilities are becoming increasingly popular," he said.
"The council recognises the value of these family-friendly spaces and the community's interest in having more local faciltieis.
"Throughout summer, water parks are a great place for cooling off and having fun.
"I encourage residents to have a look at the study and complete the survey to let us know their thoughts."
The extensive report highlights five potential sites which could house a small to medium scale water play facility: Emmett Park in Tahmoor, Memorial Park in Thirlmere, Barrallier Park at The Oaks, Wollondilly Leisure Centre in Picton and Warragamba Pool.
The council hopes to get community feedback on the locations, the use of potable or re-treated water, and residents' priorities in relation to water play facilities.
The report says the cost of a water park is highly dependent on a number of factors.
"A water park is a significant infrastructure investment that can carry significant benefits for the community," it states.
"The costs and benefits vary depending on the type of water park, site location and characteristics and co-location with other uses."
The report estimates a water park could cost $1.339 million to build and operate over a 30-year period, including a "plausible capital cost" of $500,000. Operating costs include power, chemicals, water supply, monitoring, quality testing and more.
"Including staff labour costs to monitor testing, undertake general maintenance and considering upkeep of ancillary infrastructure the total cost is estimated at $3.796 million over 30 years," the report goes on.
"Both these costs include a mid-cycle asset upgrade at the 15-year mark and two per cent escalation.
"These costs are benchmarked and generalised as it will be highly dependent on the location and final water park design."
