SOME Edmondson Park residents are bitterly disappointed with the sewerage plan prepared for their area by the state government.

In the past, they have argued that their area has not developed, despite being gazetted for residential growth four years ago, because it lacks infrastructure including a sewerage system.

As published in last week's Advertiser, NSW Water Minister Phil Costa has announced that the area's connection to the sewerage system will be brought forward to 2012.

But some residents say that because only half of the area will be connected, the other half will be no better off.

The sewerage pipeline will start from the Tree Valley Golf Course to Croatia and Dalmatia avenues and will connect 2000 to 3000 blocks to the system.

Joe Zullo, of the Edmondson Park Landowners and Residents Action Group, said he was happy that the government had committed to doing something, but what it has promised is not enough.

``They're only doing half the job. If they're going to connect the area, they might as well do the whole lot, so the whole suburb can develop,'' Mr Zullo said.

``This is only going to help one group of residents.''

Another resident who did not wish to be named said he was pleased with what the government had committed to.

``This will provide sewerage to more than half of Edmondson Park,'' he said. ``This is great news for everyone here.''

Mr Zullo and fellow residents met Liberal planning spokesman Brad Hazzard last week to ask him what the Liberal party would do to help Edmondson Park develop, if he was elected.

``He took everything on board and it seems like he understands our plight,'' Mr Zullo said.

``He didn't make a commitment one way or another but he's said that he will organise to meet with us on the site and discuss the issues.''

Mr Zullo said the the lack of a sewerage system was not the only factor stopping developing in Edmondson Park. The government infrastructure levies were also proving to be a deterrent to development.

Macquarie Fields MP Andrew McDonald said that the whole northern side of the suburb would be connected to the sewerage system, two years earlier than planned, thanks to the Mr Costa helping speed up the project.

``This is great news for the area and I'm very happy that this has happened,'' Dr McDonald said.

``All of the residents I've spoken to are very pleased.

``This will definitely get development going there.''
