"You can't just come in and take a city's pool off them."

This is the defiant message one Sydney mayor has for the state government over its plans to demolish a public swimming pool to make way for a new sports stadium.

The development of a $300 million stadium on the site of the existing Pirtek Stadium in Parramatta is set to wipe out the long-standing pool on the edge of the city and there are no firm plans to build a replacement one.

Parramatta's lord mayor Paul Garrard is demanding the government compensate the council for the pool, which is the only one in the city centre and underwent an $8 million upgrade in 2007.
