Why Energy Efficiency?

WU use old and energy intensive equipment
Electricity consumption reaches over 28-35% of
WU’s Operational Costs
Moldova is a Net Importer of energy from
unstable markets

Flow measurements at all water sources, all
water and sewage pumping stations.
Outflow measurements of individual water
and sewage pumps
Energy consumption of individual pumps and
air blower
Team used pressure measurements
equipment in order to evaluate actual
performance of pumps and pressure piping
Acoustic leak detection using correlator has
been performed

Payback period
3,7 years;
Other benefits:
Industrial productivity and competitiveness
Poverty alleviation: Water affordability and access
Reduced GHG emissions
Sustainable Natural resource management
Development goals

Complications:
14
WUs are still using energy intensive equipment, and obsolete
distribution system
Given limited human, and technical capacity WUs are not able
without foreign assistance to replicate Energy Efficiency
Political instability, and multiple elections (two local elections;
three parliamentary elections; one referendum)
Socially oriented tariffs inhibit development
Limited borrowing capacity of WUs and local municipalities
Next steps:
15
Further extension of energy efficiency programs
Continuous building of institutional capacity
Regional development in the water sector
