Projects

were

undertaken

in

order

to

meet

obligations

under

the

Treaty

of

Accession

of

the

Slovak

Republic

to

the

European

Union,

not

only

by

increasing

the

so

the

and

also

the

According

Of

Vision


The East Slovak Water Company ,
a.s
. aims to improve the quality of life of the people is its
region of operation through supplying quality drinking water via water network , and
draining away waste water via sewage systems.
VVS,a.s
. is aware of the need for further
developing of its network s of drinking and waste water conduits, in order that more and
more people can get connected to these public systems.


VVS,
a.s
. protects the environment in its range of business operations in compliance with
the regulations concerning water quality and waste water treatment. The company builds
water treatment plants, or completes the construction of partly
-
built water treatment
plants in order to increase their effectiveness.


The company is governed by the aim of creating a viable business, with a profitability
similar to that of other businesses in this field, and to increase the shareholder value.


VVS,
a.s
. sales policy is to always establish the right price for water, so that it is both
acceptable to the population and profitable for the company.


Last but not least, corporate social responsibility compels the company to endeavour to
ensure stability for its workforce with good remuneration and benefits.

Enviroment

impacts


The legal framework for environmental protection in Slovakia is now being approximated
to that of the EU. Implementing EU directives for water management in Slovakia will cost
more than 186bn SKK. EU directives stipulate the requirements for water,
eg
.

for the
quality of surface water intended for human consumption as well as qualitative parameters
for water that requires protection to sustain life in water flows. Other directives stipulate
limits for releasing waste water and gives stricter criteria regarding waste water
monitoring. This touches on, to a great extent, the current environmental issues in the
Košice

and
Prešov

regions.


In terms of qualitative protection the key issue is tackling the sources of pollution whether
they be point sources (waste water released from factories, agricultural sites and residential
areas) or area sources. Whole basins require
revitalisation
. Thus, the occurrence and
intensity of flood flows will be reduced, soil erosion and subsequent sedimentation of
streams and lakes will be lessened.


VVS,
a.s
. aims at making water treatment plants highly effective, using modern technology.
It also aims at maintaining the reliability and performance of all system pipelines in order
to keep the risks of pollution to a minimum.


VVS,
a.s
. aims to achieve the highest possible quality of treated waste water to be released


into the environment,
ie

ensuring the maximum effectiveness of waste water treatment
plants by
utilising

modern technologies and process automation, as well as maintaining the
reliability and performance of all the system pipelines to keep risks of pollution at a
minimum.

Waste water treatment


Waste water treatment VVS,
a.s
. runs 70 waste water treatments, of which 44 are owned by the company,
and of these, 40 are mechanical
-
biological and 4 mechanical. There are contracts between our company
and municipalities, based on which
werun

mechanical
-
biological waste water
reatment

plants.


The total capacity of these is 3902 l/s. The effectiveness of the treatment, as shown in BOD5 is approx
50% for mechanical plants and approx 92
-

96 % for mechanical
-
biological plants. The total amount of
organic sludge is approx. 11 000 tons a year, and 10 000 tons of dried sludge is produced.


Mechanical

biological waste water treatment plants
utilise

an aerobic treatment process with bubble
aeration, and anaerobic or aerobic
stabilisation

of sludge. Mechanical treatment plants use tanks with
openings that stabilize sludge
anaerobically
. Methods for sludge
stabilisation

are as follows: in the bigger
plants anaerobic
stabilisation

(heated
mesophile

or cold) and in the small ones aerobic
stabilisation

(
slitted

tanks, sludge boxes, simultaneous). Sludge is mechanically
dehumified

on belt presses and
centrifuges. Sludge produced in small treatment plants is transported for further treatment to large waste
water treatment plants or else
dehumified

at sludge fields.


Old treatment plants built in the 70s are being phased out and replaced by modern technologies based on
low loaded activation with aerobic
stabilisation

of sludge, which are able to withstand substantial surges
in substance load and thus ensure stability and effectiveness of the process.


Because of stricter regulations on the quality of water released, especially in terms of limits for nitrogen
and
hosphorus
, refurbishments or intensifications were undertaken,
eg

on treatment plant
Košice
,
Humenné
,
Revúca
. Plants
Prešov
,
Sabinov

are being refurbished now and new treatment plants in
Vranov

and
Lipany

are being built.
