ISSUE
The purpose of the project was the preliminary design of required works for the construction of small dams in the region of Municipality of Visaltia (torrent of Skapani) in order to meet the needs of water supply and irrigation of the broader region.

SOLUTION
The water supply and irrigation water needs were satisfied by water wells. However, many problems related to water efficiency and quality and aquifer depletion of demonstrate the need to find alternative water resources.

The construction of the small dams addressed these problems with an integrated water resources management approach by utilizing the winter surface waters runoff of Skapani torrent.

The selected locations and the required works were the following:

Location 1: The water flows into the reservoir with a partial diversion of the supply torrent through a gravity pipeline. The embankments of the reservoir have a total length of 370m and a height of 10m. The slopes of the banks were 1:2.5 (vertical – horizontal) for the downstream of the basin and 1:3 (vertical – horizontal) for the upstream of the basin. The volume of the reservoir was estimated at 200.000m³. In the reservoir embankment a spillway was constructed. The proposed works included the construction of a perimetric collection trench upstream of the river where the collected stormwater is gathered from the surrounding slopes and flows into the river.
Location 2: The water flows into the reservoir with a partial diversion of the supply torrent through a gravity pipeline. The embankments of the reservoir have a total length of 370m and a height of 10m. The slopes of the banks were 1:2.5 (vertical – horizontal) for the downstream of the basin and 1:3 (vertical – horizontal) for the upstream of the basin. The volume of the reservoir was estimated at 200.000m³. The proposed works included the construction of a perimetric collection trench upstream of the river where the collected stormwater is gathered from the surrounding slopes and flows into the river.
Location 3: The water flows to the reservoir with a partial diversion of the supply torrent through a gravity pipeline. The embankments of the reservoir have a total length of 370m and a height of 10m. The slopes of the banks were 1:2.5 (vertical – horizontal) for the downstream of the basin and 1:3 (vertical – horizontal) for the upstream of the basin. The volume of the reservoir was estimated at 200.000m³. In the reservoir embankment a spillway constructed. The proposed works included the construction of a perimetric collection trench upstream of the river where the collected stormwater is gathered from the surrounding slopes and flows into the river.
Location 4: The water flows to the reservoir with a partial diversion of the supply stream through a gravity pipeline. The embankments of the reservoir have a total length of 370m and a height of 10m. The slopes of the banks were 1:2.5 (vertical – horizontal) for the downstream of the basin and 1:3 (vertical – horizontal) for the upstream of the basin. The volume of the reservoir was estimated at 200.000m³. In the reservoir embankment a spillway constructed. The proposed works included the construction of a perimetric collection trench upstream of the river where the collected stormwater is gathered from the surrounding slopes and flows into the river.

BENEFIT
The design of the small dams was implemented in light of integrated water resources management and solved the water supply and irrigation problems in Municipality of Visaltia.
