Greenfield drinking water, where it comes from and how it gets to your homes

In the context of the global health crisis, water, along with soap, is the
the most important ally in the fight against covid19, has once again become one of the topics
Preferred discussion topics of our neighborhood residents.

Water is the absolutely indispensable substance for life, regardless of its form
add. Therefore, ensuring a very good quality drinking water supply for
Greenfield residents have been, are, and will remain one of the most
important concerns for Impact. And to provide more substance
to this declaration, within this article we will explain in detail why
drinking water quality Greenfield is at this moment one of the most
from Bucharest, being in fact equivalent to bottled drinking water,
in the magazine.

Origin

The water for household consumption in Greenfield Residence is drawn from
a depth of 225 – 240 meters through four boreholes (F1, F2, F3, F4)
organized into two water management areas (GA1, GA2). A borehole well has on average
An exploitable optimal flow rate of approximately 3.7 – 4.7 liters per second. Water
taken from underground is used for hygienic and sanitary purposes as well
and for ensuring the fire reserve.

Treatment process

After extraction from wells, the water undergoes physicochemical treatment.
to meet the required standards for consumption, both for drinking or cooking,
as well as for personal hygiene. Water purification is done at the stations
appropriate treatment for each water utility, located underground in areas
sanitary protection.

Each treatment station consists of:

–
Chlorination unit (pump)
sodium hypochlorite dispenser

–
Storage tank
(also acting as a reaction basin)

–
Pumping group

–
sediment filter
(screen filter with self-cleaning function),

–
activated charcoal filter

–
UV sterilization filter.

The water extracted from drilling on the supply pipeline is first treated with
sodium hypochlorite for the removal of harmful elements such as hydrogen
sulfate or ammonia, but also for increasing the speed of iron oxidation,
manganese and oxidizable organic matter. This is followed by the stage of
oxidation, which takes place in 250 cubic meter storage tanks, duration
with this stage taking approximately 5 hours.

Water storage tanks intended for current consumption (potable,
(technical and sanitary) as well as the intangible fire reserve are
made of reinforced concrete with specific waterproofing. Tank volumes
are 200 cubic meters for the GA1 water household and 2×250 meters
water utility cubicles GA2.

The water is then pumped by the pumping unit into the filter
sediments where suspended matter up to 50 microns is retained.

The next stage of filtration is Granular Activated Carbon filtration,
used for correcting taste, smell, and color parameters, but also
to remove any traces of free chlorine, trihalomethanes (THM's), chloroform,
insecticides, herbicides, polycyclic aromatic hydrocarbons, biphenols
polychlorinated, volatile organic compounds, and hundreds of other potential
Organic contaminants that can be present in water.

The final disinfection that eliminates bacteria or viruses is carried out with
UV radiation installation assistance. After this stage, the water has parameters

potable, as evidenced by all tests (both internal and those conducted by the Public Health Directorate)
achieved to date.

Water Testing Procedure

Who are you for
residents of Greenfield Residence neighborhood is permanently subjected to analyses of
laboratory by the National Institute for Research - Development for
Industrial Ecology. The parameters analyzed are in
number 17, namely: residual chlorine, ammonium, aluminum, conductivity,
chlorides, color, hardness, iron, manganese, nitrates, nitrites, oxidability, pH,
sodium, sulfur, and hydrogen sulfide, sulfates, and turbidity. 

These analyses
Check that the analyzed parameters fall within the maximum concentrations
admitted by Law 458/2002 on the quality of drinking water.

Test program
and water quality verification is required by the Public Health Directorate
municipality of Bucharest (D.S.P. Bucharest) and involves complex analyses (totaling
57 mandatory tests throughout the year, according to the attached procedure.

Outside of testing
required by the test program, Impact performs tests
periodic supplements, for parameters not included in the measurement lists
required, as well as to use multiple laboratories for testing
problems.

Analysis bulletins
are made available to AIH, which in turn makes them available (to
to all interested parties.

Also, starting in May, the analysis reports
will be available within the Helpdesk. To benefit
account on the platform, we remind you that you must be the owner of the apartment
and have a validated account. Each apartment can have only one account
Help Desk.

Measurements
So far, the tests confirm permanently that the drinking water from Greenfield
Are the quality parameters at least equal to bottled still water, which can be

We hope all the information presented above is useful to you and will
build your confidence in the quality of services made available
Greenfield residents.
