Landfill waste (Roscommon Landfill, closed)
Urban Run-off
Combined sewer overflows
The main pathway in the urban environment will be pipes in the form of primary or secondary discharges from WwTp, Combined Sewer overflows, pumping stations and misconnections.

An Taisce Report
The Mutton Island Waste Water Treatment Plant (D0050) was opened in 2004 with a claimed capacity of 90,000 people equivalents.
In 2014 it was upgraded to have a claimed capacity of 170,000 people equivalents (reduced by Galway City Council to 145,000 people equivalent to allow for Summer tourists). Local papers carried of stories in 2004 (and again in 2014) of how the Mutton Island Waste Water Treatment Plant would guarantee the beaches in Galway City would now be safe to swim in.
The reality however is that is not true.

River Urban Run Off Pressures
Significant pressures have been identified for waterbodies that are At Risk of not meeting their water quality objectives under the Water Framework Directive. While there are a multitude of pressures in every waterbody, the significant pressures are those pressures which need to be addressed in order to improve water quality.
Many of our waterbodies have multiple significant pressures.
A robust scientific assessment process has been carried out to determine which pressures are the significant pressures. This has incorporated over 140 datasets, a suite of modelling tools, and local knowledge from field and enforcement staff from the Local Authorities, Inland Fisheries Ireland and EPA.
Urban run-off or diffuse urban pressures are mainly caused by misconnections, leaking sewers and runoff from paved and unpaved areas. Impacts from diffuse urban pressures include nutrient, organic and sediment pollution.
Irish Water Trade Effluent Licence Register
Trade effluent is any liquid waste that is discharged from business premises to public sewers
Trade effluent discharges to sewer are regulated by Irish Water or the EPA. You must have a trade effluent licence or an EPA licence to discharge trade effluent to the sewer. The type and scale of activity will determine the regulatory authority responsible for licensing the trade effluent discharged to the sewer.
A trade effluent licence sets out conditions that businesses must comply with. These may include:
- The nature, composition and volume of the trade effluent discharge
- The method of treatment, the location of discharge and the periods during which discharge may be made
- The taking and analysis of trade effluent samples and the trade effluent records that must be kept
- Applicable charges for discharging trade effluent, as approved by the Commission for Regulation of Utilities (CRU)
Irish Water maintain a database of all trade effluent licences
Note 1.
Irish Water will provide an up to date Register on request, email dischargetosewer@water.ie
Note 2.
A trade effluent discharge to sewer licence is a legal requirement if a business discharges trade effluent to a public sewer. If a business is discharging to surface water infrastructure, they need to contact the relevant Local Authority for a licence.
Note 3.
Unclear what happens with licensing in sewer systems without a treatment plant, eg Arklow, Wicklow
