Ep53 – Onsite wastewater treatment in Ireland

Connecting your sewage to the mains is not always an option when you’re building in the countryside. You might need to install an onsite wastewater treatment system instead, which is a mini sewage treatment plant. In ROI, if an onsite system is not feasible you will more than likely be denied planning permission.

Cathal Keane of Graf Environmental gives us a crash course and highlights what you need to know, including:

– Who needs an onsite wastewater treatment system.
– What’s a typical setup? Brief overview of primary, secondary and tertiary treatment.
– What are the requirements in NI and ROI and how they differ. Main Building Regulations requirements to be aware of.
– The process of choosing an onsite wastewater treatment system in NI and ROI.
– Maintenance and keeping the system working at its best to protect environmental and human health.
