•Over a period with substantial investment it is possible
to rationalise the number of water supply sources/

in operational efficiency.

Water Services Pricing Policy
‘marginal capital costs’ generally means the cost
associated with increasing the capacity of domestic only
infrastructure to (i) provide capacity for existing nondomestic 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.
Donegal County Council – Presentation to Oireachtas Joint Committee on Environment
Transport Culture and Gaeltacht
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

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.
