Meaning of “cluster”

Common water infrastructure: water supply network,

reservoirs, pumps, wells or water abstraction are used

by more then one locality.

Common organization of water services: one Apa Canal

or municipalities hire one company to provide

maintenance services.

Water services are organized separately, but PIU (project

implementation unit) prepares larger investment projects

and provides some services for municipal water

providers; this could be also a transitional solution

before joint organization of water services.

Methodology used to prioritize clusters in

Riscani Rayon The cluster proposal is based on the technical options

for development of water supply infrastructure which will

be presented later.

The development of wastewater infrastructure was not

used for cluster proposal because the lack of water of

good quality is the major problem.

Most of the localities in Moldova (except urban area) are

small, located far from one another and with hilly

topography. Thus, the development of a larger

wastewater network would be too costly. Yet, there is no

other option than for a larger water supply network.

Methodology used to prioritize clusters in

Riscani Rayon For localities where the technical option was not

prepared, the cluster proposal was based on other

similarities (localities with access to water, close

location or others).

For each technical option, the DGC (Dynamic Generation

Cost) indicator was calculated in order to determine

which option is more cost effective.

Cluster 2

Cluster 3


Cluster 2

Cluster 2 covers 4 localities (Reteni-

Vasileuti, Reteni, Braniste, Avrameni)

which are rich of good water sources, thus

were not included in the water network

covering other localities in the rayon;

Population living in the cluster: 1,448;

Cluster 3

Cluster 3 comprises remaining localities

not included in Cluster 2;

Population to be connected: same as for

cluster 1;

Population living in the cluster: 69,971

Cluster 4

Cluster 5


Clusters 4 and 5

Based on division of Rayon into two water

networks supplied from different sources

(Prut River for the west part and Soroca-

Balti transition pipe for the east part);

Technical option was not prepared

because investment and operating costs

are much higher then for one water source

(cluster 1 or 3);

Thus such a division is not recommended;

Cluster 6

Cluster 7

Cluster 8


Clusters 6,7,8

This is a variation of the division for cluster 4

and 5 but 4 localities which are reach of water

constitute a separate cluster;

This division into clusters 6, 7, 8 is also not

recommended for the same reasons as clusters

4 and 5;
