Council testing turns stream water in Sean Walsh Park green
By Mark Keane
A STREAM in Sean Walsh Park mysteriously turned green yesterday, much to the surprise and concern of park walkers.
However, The Echo has learned that the change in water colour is not some remnant from the recent St Patrick’s Day celebrations but down to testing of the storm water drainage system by South Dublin County Council.
On Monday, the local authority carried out dye testing of the drainage system in the vicinity of The Square to better understand drainage flows in an attempt to resolve reoccurring flooding problems being experienced in the area.

When contacted by The Echo, the council said: “South Dublin County Council carried out dye testing of the storm water drainage system in the vicinity of The Square Shopping Centre on the 26 March 2018.
“The purpose of the test was to understand drainage flows in the local area in an effort to resolve reoccurring flooding problems being experienced in the area.
“The drainage in the area is complicated and required the use of dye.”
Despite its eye-catching and suspicious-looking appearance, the dye is environmentally safe and routinely used for this purpose, according to South Dublin County Council.
The council added the deep greenish colour was due to the dye entering the stream in an “unusually quick manner”.
