Who we are

Welcome to IWTA

The Irish Water Treatment Association was established as an extension of DETA (the Domestic Effluent Treatment Association) to encompass the growing need to safeguard and conserve the country’s precious water supply.

Irish Water’s primary goal is to promote the conservation and reuse of clean water both at a domestic level and within industry. It also aims to promote the treatment and satisfactory disposal of domestic wastewater thus ensuring the entire water cycle is managed effectively and efficiently.

Our Primary Objectives

Its primary objectives are:

    of the appropriate regulations for domestic on-site water and wastewater treatment
  • To be Ireland’s leading voice for domestic water
    conservation reuse and recycling
  • To highlight the importance of water as a
    precious resource and to promote its conservation reuse and recycling on the island of Ireland
