Alternatives to water supply and wastewater treatment to be discussed at DIT and An Roth - Engineers Ireland lecture



27 November 2013:With water and wastewater charges due to be collected in 2015, saving money and exploring alternative approaches to water supply and treatment is certainly a topical subject!

This will form part of the discussion at An Roth - Engineers Ireland and DIT’s bilingual public lecture taking place at Dublin Institute of Technology (DIT) Aungier Street on Thursday 5th December at 6.30pm.

The talk is on An Cuardach ar Infreastruchtúr Pobail-Bhainistithe Athléimneach in Éirinn - The Search for Resilient Community Managed Infrastructure in Ireland.

Lecturers Seán Ó hÓgáin and Liam McCarton from the School of Civil & Building Services Engineering, DIT, will address the infrastructural issues faced by communities in Ireland including water supply, wastewater treatment, energy supply and transport.

A series of case studies will be presented and these case studies will include communities from Ireland, Scotland, South America, Africa and Singapore. One such case study looks at research carried out in Ceathrú Chalaidh National School in Westport, County Mayo, where over half of the total non-drinkable water usage over a 21 month period in the school was provided by rainwater harvesting.

Reed and willow beds are a viable alternative for wastewater treatment also according to research carried out by DIT with Fingal and South Dublin County Councils and these case studies will be discussed at the lecture.

The technology and the community structures developed to oversee and administer the running of projects will be outlined. Over the past four years, the Scottish island Eigg has had 85 per cent renewable electricity – this case study will be highlighted at the lecture.

The applicability of technologies to Ireland will be discussed together with the advantages and disadvantages associated with each and the barriers to adoption of these technologies in Ireland. Finally suggested entry points for Ireland to develop a feasible community managed self-supply infrastructure strategy will be identified.

Through their own experiences and applied research with DIT’s ‘Development Technology in the Community’ (DTC) research group, Seán Ó hÓgáin and Liam McCarton have worked with communities, NGO’s and Governments in Sierra Leone, Niger, Nepal, Bolivia and Peru.

Their areas of expertise include water supply and wastewater treatment, sanitation, self-supply for small communities, reed and willow beds for wastewater treatment, rainwater harvesting to augment mains supply as well as post climate change technological design and post tsunami water and sanitation reconstruction projects.

The lecture is organised by An Roth – Engineers Ireland and DIT and will take place in DIT Aungier St., on Thursday 5th December with a welcome reception at 6.30 p.m. in Java City on the ground floor followed by the lecture in Room 2046 at 7p.m.

Everyone is welcome and rsvp to
