Irish Water says it's hopeful it will get approval for a major new waste water scheme for Dublin that's expected to cost over €500m.
A planning application for the Greater Dublin Drainage Scheme is being lodged with An Bord Pleanala today.
The scheme includes a new treatment facility in Clonshaugh, and a storage facility at Newtown near Kilshane Cross.
Project manager Jane Chambers from Irish Water says the project shouldn't have a major impact on local communities.
"We have insured that all of the issues in terms of traffic, odour, dust - they are all captured in our environmental studies.
"And we have medication measures that have been built in to construction".
She says it's a huge scheme.
"It involves the construction of a new orbital sewer which will stretch from Blanchardstown across to Clonshaugh, where the new waste water treatment plant will be constructed.
"And then from Clonshaugh out into the Irish Sea there will be an outfall which will terminate six kilometres from the coast road of Baldoye Bay".
