      I am trying to find out what a developer is required to do under Irish Planning in respect to making connections during construction into existing foul and sewer lines in estabished housing estates.

      My parents property is in south dublin, our neighbour sold a plot in their rear garden to a third party developer who sought and obtained planning permission from DLRCOCO for a ‘one off’ infill detached property set back from the original building line in this 40 year old housing estate. The original sewer line runs across all rear gardens and meets the public sewer to the rear of our property. The developer was granted permission by our neighbour to connect to their sewer line in their rear garden, this additional infill development was not envisaged when the existing 40yr old sewer line was installed by the estate developers Abbey Homesteads and our concern is that this additional connection will result in over excessive pressure on the piping.

      The deveopers architect has advised that such direct connections into the original sewer line is in keeping with good practice and is not in breach of planning permission granted. There is no clear reference to an independent sewer line connection referred to in the grant of planning consent. Any information on precedent for newly established connections for one-off infill developments such as this would be of great interest as I must contest this on my parents behalf.

      Why must you contest this?

      If there is single additional unit being constructed in what sounds like a decent size estate how have you reached the conclusion that this additional unit will put undue strain on the waste water capacity of the area?

      A family of 6 in one of the existing houses would use more waste water capacity than two households with no children.

      yeh this doesn’t sound like an issue whatsoever. The construction of infill housing in over-sized side gardens and in badly designed open spaces is a positive trend in older suburbs and there’s no reason to contest it on any grounds other than loss of residential amenity by overlooking etc. I’d be more concerned about new estates being built on bogs and marshes in the countryside than this…

      As PVC King said, if an empty nester in yer estate sells up to a fmaily with 6 kids it would have more impact than a new house with a childless couple for example

      And as far as I know, connecting to the main sewer is standard. What’s the other option? A septic tank? in the city? hardly….

      I think you need the advice of a reputable drainage engineer before you consider “contesting” this (do you mean an appeal to the board?). There can be drainage issues in certain parts of DLR e.g. around Glenageary/Killiney that can scupper plans for infill housing but I would doubt if you could base a planning objection on what you have outlined. I am sure the local authority would dispute the facts from their waterworks Dept. with any advice you may get from elsewhere. If this is an already granted PP, go to the local authority office and read the full file of the application to see if there is a report from the drainage dept. included in the file.

      I would suggest your parents attempt to create a constructive dialogue with their neighbours and the builders though before you set off on a confrontational path.

      Did you object to the development before permission was granted? I don’t think you can appeal the decision if you had not done this.

      I see no reason why an extra house would but extra pressure on the drainage line, or the sewer.
      The drain could never be design to hold just enough for each house on the line. That would be silly. Pipes come in standard sizes, if extra houses to be added in the future was taken into account when the original pipes were sized, they would probably be the same size

      If it were an issue, im sure enviromental services would of picked up on it.

      Half-Time during an Ireland Match would put more pressure on the system than an extra house.
