About Us

Ian Heffernan & Associates was formed in March 2012. Ian Heffernan is a fully qualified Civil Engineer based in Glenealy, Co.Wicklow. Ian is a site suitability assessor, M.I.E.I, specializing in site suitability assessments, septic tank inspections, full installations, percolation testing, project management, map certification & building energy ratings (B.E.R.’S). We also carry out applications for discharge licenses , either to groundwater or surface water.

The main aim of Ian Heffernan & Associates is to assist the general public in relation to the new septic tank legislation and to provide all the necessary expertise required for the home owner/commercial business. We offer a one stop system, whereby we can call to your site and examine your existing septic tank and form an opinion as to whether the system is compliant with the current EPA Code of Practice. At this point we can offer solutions going forward from remedial works to a complete new system if required. We have ten years of experience in all aspects of site assessments. We have worked on designs for one off houses up to commercial developments.

Our overriding focus is on performance, we take our quality, safety and environmental responsibilities extremely seriously and pride ourselves on our standards.

Teamwork lies at the heart of our culture. We work together with our customers, professional teams and our supply chain to develop innovative and value adding solutions for our clients.

Relationships have been the key to our past success and will be more important than ever in the future.  Our team is committed to working closely with you to deliver total satisfaction on your projects.
