The operation and management of public wastewater infrastructure, including control of emissions, is a matter for the relevant water services authority. Appropriate capital works relating to the control of emissions are funded by my Department in the provision of new or upgraded infrastructure.

Methane is an odourless gas, which in the case of wastewater infrastructure, is most usually associated with the routine production of methane as a by-product for treating wastewater sludge.
