On Friday 16-06-2023, DEYAP presented the study for the new WWTP (Wastewater treatment plant) of Aggeria to the public and citizens. It is a project that, together with the corresponding sewerage network, was designed to solve the problem of wastewater treatment in the wider area of Aliki and Aggeria. The project brings together the following characteristics:

1) It was designed within the municipal area of 628.7 stremata, on the hill of Tripiti.
2) The location of the site, on the hill of Tripiti, was chosen in order to cause the least
possible visual disturbance, as it will not be visible to most people, except from the sea. At the same time,
is far from the settlement, while the use of modern machinery will not cause noise or disturbance
from odors.
3) It will be a state-of-the-art WWTP that will provide recycled water of 3rd level treatment, suitable for
unlimited irrigation and peri-urban use.
4) It will treat wastewater using MBR membranes, which is considered the most modern and efficient
method for the production of water for reuse.
5) It is designed in such a way that it can process 300m³/day, which is expected to
is the supply in winter, up to at least 1870 m³/day in the summer months.
6) The location of the new WWTP under design allows for future extension of the network to Dryo.
7) The modern design of biological purification plants, using state-of-the-art equipment,
allows for the construction of facilities with very little land cover, compared to older
technology that required large open tanks. The specific processing facility
will cover an area of 7.2 hectares, i.e. just 1.1% of the total available area.
8) Next to the new WWTP, a small environmental park was designed, accessible to the public, which will have
playground, lawn, gardens, small pond and will aim to highlight the environmental value of the
project, as well as to raise awareness of environmental issues among society and children and to
water saving. Its area will be approximately 9.1 stremata (1.5% of the area)
9) The produced water will not be discharged into the sea and no underwater pipeline will be built, but will be used as follows:
a. The entire forest area of Trypiti will be irrigated
b. The old landfill and the adjacent forest area in Faranga will be irrigated.
c. It will be used for irrigation in the neighbouring environmental park.
d. The excess will be directed to adjacent recharge wells to create an underground check dam.
10) Finally, next to the above facilities, a 1MW PV Park of approximately 20 hectares (3.2% of the area) will be designed to cover the energy needs of the project. This means that the project will have a zero carbon footprint during its operation and will cover all energy needs, including the pumping stations that will be required to transport wastewater from the settlements to the WWTP.
11) The budget of the project is 8.380.000 €. This includes the cost of the construction of the park (approximately 390.000€)

In general, after much study and research in recent years, DEYAP has concluded that this point is the optimal solution, for the following reasons:
1) It is far from settlements and will cause zero nuisance from odours, noise pollution, visual disturbance and traffic.
2) It is far away from beaches that can be visited.
3) It is at a point where the treated water can be disposed of in many alternative useful ways rather than dumping it into the sea. In general, we in Paros should use recycled water for irrigation in the coming years, with the aim of saving the same amount of drinking water to meet the ever-increasing needs for water supply.
4) It will enable the utilization of the produced treated water.
5) It gives the opportunity to use renewable energy sources to meet energy needs.
6) It is on municipal land and therefore there is no land acquisition cost.
7) The total land coverage, including complementary projects (PV plant and environmental park), is only 5.8% of the total available area
