Drinking Water-Irrigation
Client: Community of Thirasia
Year: 1997
Budget: 1.000.000€ (1998 prices)
ISSUE
The purpose of the project was the 
final design of the external water supply network and the water distribution network for the village Manola within the community of Thirasia.
SOLUTION
The island’s communities had neither water distribution networks nor storage facilities (water tanks). The island’s water was supplied by rain storage tanks with a capacity of 5m3, located on the roofs of the houses. Furthermore, water was being transported by ferry boat from the island of Thira. The main problem was the lack of an adequate water storage tank, and the construction of a suitable distribution network.
The table below shows the total peak population for the village of Manola, for each design phase.
| Peak Population of Served Communities | ||||
| Community | Population 1981 | Projected Population in 1994 | Projected Population in 10 years | Projected Population in 20 years |
| Thirasia (village Manola) | 245 | 250 | 253 | 255 |
| TOTAL | 245 | 250 | 253 | 255 |
The design of the project was pursuant to the Greek Presidential Decree 696/74. The design of the pipelines and the water tank was based on a 20-year horizon. Specifically, the project included:
- two (2) water tanks with capacities of 1.000m3 and 300m3 and dimensions of 26m x 11m και 3m x 13m respectively. The tanks were constructed of reinforced concrete with circular and rectangular sections
- supply pipelines for the tanks, with a total length of 4.500m and diameters of 100mm and 250mm
- water distribution pipelines made of galvanized iron, with a total length of 1.100m, and diameters of 63mm
The design of the water supply and distribution network solved the problem of drinking water supply in the community of Thirasia.
