For the water to reach our customers' taps in good drinking state, Apa Nova Bucureşti works daily throughout the water treatment and supply cycle.
Until it reaches your glass, the drinking water supplied by Apa Nova Bucureşti comes a long way, starting from the river water stage to that of just good to drink water. Checks are carried out upstream from the water entering the treatment plant in order to detect any possible accidental pollution of water. Allert stations permanently supervise the river water quality (24 hours a day). Should any problem be detected, the treatment sequence is adjusted or the water admission is immediately stopped.
Water Catching: The water to be used for consumption is of subsurface origin or superficial water. It is pumped by boring (up to 100 m deep) or taken on the surface. The water is first filtered by a simple grid to stop the big waste (leaves, insects, particles bigger than one millimeter). Then, it passes through finer grids which retain smaller waste.
Coagulation, Flocculation and Decantation of Water: Very fine particles, suspended in the water, gather in the shape of flakes under the action of a coagulation agent. Such flakes, heavier than air, settle on the bottom of the tank and thus 90% of the suspended matters are removed.
First Filtration: The water passes over a sand filter by means of which the still visible and not yet settled matters are removed.
Ozonization: Water is treated with ozone which has an antibacterial and antivirus action.
At the same time, this gas, mixed with water, acts upon the organic matters by decomposing them. The ozone improves the water colour and taste.
Second Filtration: Water passes over an active coal filter which retains micropollutants and part of the organic matter decomposed by the ozone.
Water Chlorination: Chlorine is added on exit from the treatment plant and at various points of the distribution network in order to destroy bacteria and avoid their growth, and to maintain the water quality on its entire route through the network.
Water Storage and Distribution: Once become drinkable, water is conveyed through pipes or aqueducts towards the reservoirs. Such pipes and aqueducts are specifically designed for conveying the drinking water in maximum safety conditions. Drinking water storage is done in closed reservoirs (underground reservoirs or surface constructions). Drinking water is brought up
