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

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
