County Donegal – Proposed Water Infrastructure
•Over a period with substantial investment it is possible to rationalise the number of water supply sources/ schemes to less than 20 with considerable improvements in operational efficiency.

‘
marginal capital costs
’ generally means the cost associated with increasing the capacity of domestic only infrastructure to (i) provide capacity for existing non domestic users, and (ii) provide spare capacity for future non-domestic and future domestic users.
In practice the marginal capital cost of doubling the capacity of a treatment plant will in general be less than double the capital cost cost of a domestic only plant.

Water Services Pricing Policy
•the non-domestic marginal capital costs to be recovered from the existing normal non-domestic sector by spreading the cost over a suitable period (through borrowings) and recovering the cost as an element of the overall water service charges for non-domestic users. •the spare capacity marginal capital costs (future domestic and future non-domestic) to be recovered from development contributions Donegal County Council – Presentation to Oireachtas Joint Committee on Environment Transport Culture and Gaeltacht
Water Services Pricing Policy
Anomalies •Core operational costs have also been rising steadily due to –increased provision of infrastructure and services, and –new and higher environmental and performance standards. (EPA Wastewater Licensing) • Therefore the Counties with the greatest requirements for standalone infrastructure, lower population densities, and greatest environmental sensitivity will incur the highest unit operating costs and water services core operational charges.
