  • Karl has maintained our Puraflow system for over 10 years and has always provided a prompt and thorough service when we need it.
    From replacement pumps, reinstalling filter modules and general advice, I’d have no hesitation recommending him – he definitely knows his s#!t.

  • I had a problem with my septic tank and employed Dolan’s Environmental and Plant Hire to install a new treatment system eight years ago. They have also maintained this for me since then. The installation was done in an efficient and economical manner and their after-sales service since then has been excellent.

  • We have been using Dolan’s Environmental& Plant Hire to maintain our group waste water treatment system for the last year or so, after having several issues with pumps and the system overflowing and not working for a long period, we couldn’t get anyone whom could come in and assess the problem and put in place a solution to our problem. We contacted Dolan’s Environmental & Plant Hire and I was in contact with Karl who was very helpful and knowledgeable about what he was talking about and he said he would come visit our site and assess the problem.  The next day he was on site and diagnosed the problem and put together a detailed list of what was required and did a quote for the intended works.  We got all paperwork sorted very promptly and he took it from there.

    There was a major issue with the electrical control panels with the system and the pumps he had all sorted and redesigned and working in one day and everything has been working great since.  His entire time are a pleasure to work with and are very helpful in explaining the working of the system in a way that anyone can understand.  They provide a complete professional service and I would have no problem in recommending them to anyone whom has a septic tank or treatment tank at their house.  It Has been such a relief to have them on board and since the works have been completed they have been back on site carrying out and inspection to ensure all operating correctly as per our initial agreement.  They really are a one stop shop for sewage system repairs and maintenance.
