The proposed operation comprises two sub-projects (supplies). The 1st sub-project “Replacement of vehicles with new energy, efficient and low emissions” concerns the replacement of existing vehicles with new, better efficiency and lower fuel consumption which can achieve a significant reduction in fuel consumption and operating costs. DEYAE intends to replace vehicles that are approaching the end of life and/or older vehicles, with energy-efficient vehicles. It is proposed to replace a total of fifteen (15) vehicles of the fleet of DEYAE with more modern models.The 2nd sub-project “ENERGIA RESERVATION Pumping Pumping Pumps OF D.E.A.E.A. EGOMENICHAS” concerns the energy upgrade of pumping installations (boilings and propelling pumps) of the water supply network managed by D.E.Y.E.E.E., the replacement of the power plants of the energy efficiency of the thermometers and the use of the supercharged energy, with the high speed of the energy, with the high speed of the energy.
