Over 46km of the sewer network is being cleaned and surveyed for defects to allow for repairs

Irish Water working in partnership with Fingal City Council have commenced works to upgrade the sewer network in Blanchardstown and surrounding areas. Over 46km of the sewer network is being cleaned and surveyed for defects to allow any repairs to take place. 

To date, 90% of the sewer cleaning and surveying work has been completed across the Carpenterstown, Clonsilla, Clonee, Mulhuddart, Blanchardstown Village, Corduff and Damastown areas. The survey work enables us to pinpoint where there are cracked, broken or obstructed sewers that need to be repaired.

82 repairs completed to date in Castleknock area

In the last two months the sewer repair works have commenced in the Castleknock area with over 82 repairs completed to date. Irish Water will continue to carry out repairs across the sewer network and it is expected that work will continue into early 2019

The existing sewer network serving Blanchardstown, like all sewers, needs to be maintained. Defects in sewers include the build-up of debris and foreign objects such as stones, bottles, baby wipes, accumulating fats and greases and intruding tree roots. If these are not removed they will ultimately cause the sewer to block and overflow, causing localised sewer flooding. A number of structural defects will also be repaired such as cracked, fractured and broken pipelines and defective connections. These works are required to protect the sewer network against failure and sewer flooding.

Minimising the impact on the local community

Once defects have been identified they are assessed so that the optimum design solution is determined. The majority of the sewers repairs will be carried out by trenchless technology to minimise the impact of the works on the local community. 

These works involve the installation of liners within the existing sewer network in order to protect the normal operation of the sewer network. The majority of works will be carried out between normal working hours however there are some small areas where night work will be required to mitigate disruption to traffic, pedestrians, local businesses and local services.

Think Before You Flush

To help prevent blockages in the sewer network we are asking the public to refrain from putting items into the sewer and to follow the advice in the Think Before You Flush section. Items such as baby wipes, face wipes, cleaning wipes, nappies and sanitary products should never be flushed down the toilet. Fats, oils and grease should never be poured down the sink as they all cause blockages in our sewer network. These types of blockages can cause sewer overflows and sewer repairs and cleaning to be carried out.
