      I have ten acres of agricultural land in Limerick. It has good road frontage and I felt it was in reasonable condition. It currently used for dairy farming and I would have thought that I would have been able to get planning. It looks like a perfect area for a house to the untrained eye namely it is level and seems to be dry etc. I recently hired an expert to check the percolation. He examined a good number of different trial holes throughtout the land. Apparently all of the trial holes failed the precolation tests. Limerick County Council will not allow any planning application to proceed unless the percolation tests have passed. Is this the end of the road regarding planning? Can soil etc be imported into the site to improve percolation or is there any other methods to address this situation? Maybe someone has experience of a similar problem? Any help would be appreciated…Thanks

      Surly, the person that did the tests can advise you on an alternative solution. A percolation test is only one part of a site assesment, positions of local boreholes, groundwater protection zones need to be taken into consideration also.

      The main suppliers of treatment plants normally carry out a SA, with their fee being taken off the system if purchased.

      I would advise on arranging a pre planning meeting with your LA first, that way you can see if you meet the LA requirements, housing need, house type, site suitability etc. If they are in favour of the development then proceed with an SA, which can be included in the planning application.

      Thanks for the help folks. I am still waiting for my engineer to get back to me and just doing a little research on my own!! The key issue here is that Limerick County Council will not allow any domestic waste system to be used for a domestc dwelling (no matter how advanced!) if the site does not first pass the percolation test. They have a panel of testers who will carry out the test. You must use one of their approved testers. if your site fails the test, then you will not be allowed to proceed. It is a very rigid system considering how advanced some of the modern domestic waste treatments systems are. What I want to know is how do I go about preparing (if this is possible) the site so that it crosses the first hurdle namely passing the percolation test?.. Thanks for the help

      you cannot ‘prepare’ a site for testing… this has the insinuation that you want to cheat the system. i dont think anyone here will advise how to do this.

      The only real thing you can do is to do tests yourself (or pay a specialist) in different areas of the site to see where the best percolation is.

      Excuse me Henno, I was not insinuating anything of the sort. If you had read my original post you would have seen that I have indeed retained an expert to test the site. The results are on the post. If you had also looked at the link to “ask aboutmoney” above, you wouild have seen how soil can be imported onto the site. I am not an expert on this area, that is the reason I am doing some research myself. If you had taken thetime to follow the thread you would have seen where I was heading regarding site preparation.
