Technical Infrastructure


A new double very-high-voltage supply line 2 x 110 kV from Výškov distribution plant was built in 2007. It will be completed with a single supply line 1 x 110 kV from Žatec distribution plant. The construction of a new transformer station 110/22 kV was completed in 2018 and it ough to cover increasing consumption of the industrial zone in the future.


Connection charge due to reserved electricity power and realization connection of the electricity in standard tension level 22 kV is 800.000 CZK/MW. This charge must be covered by an investor. The possessor and the operator of electrical network is the ČEZ Distribuce, a.s. Company.

Drinking Water

Connection to the existing water main DN 300 running along the western border of the site, balancing water tower with storage capacity of 400 m3, actual total capacity is 10 l/sec (864 m3/day) with opportunity to increase up to 25 l/sec (2 160 m3/day) based on real needs of the zone. Maximal daily capacity is 57 l/sec.


Service Water

Service water supply is connected to the existing service water main DN 500 at the northern part of the energy centre, balancing reservoirs with storage capacity of 2 x 1 500 m3 serves for satisfying consumption fluctuation and as a reserve capacity for firefighting needs.



A branch from the existing high-pressure pipeline DN 200 running along the south-eastern border of the site to the Triangle zone, reduction station and two branches of medium-pressure pipeline along the periphery of the central part of the zone have been built. The Strategic Industrial Zone Triangle has total capacity 15 000 m3/hour (from the existing south branch is available 5 000 m3/hour, from the existing north branch is available maximally up to 10 000 m3/hour).


Rainwater Sewerage

The rain sewerage is leading from northern half site through two reservoirs into the river Chomutovka, from southern half site via three rainwater reservoirs into the river Ohře.The rain sewerage capacity in the Triangle is cca 8,6 l/s from 1 hectar.


Wastewater Sewerage

Gravitation sewerage with delivery to Staňkovice pumping station and further to wastewater treatment plant at Žatec with daily capacity 800 m3 served up to the end 2018. Maximal daily capacity is 17 l/s. In the frame of development conception of the Strategic Industrial Zone Triangle a new water treatment plant was built up with capacity 1 800 m3/day. The operation started in January 2019. Required values of pollution indicators are available here, please click [PDF 242 KB].


Technological Sewerage

The Ústí Region constructed treatment plant for cleaning technological wastewaters including public infractructure in June 2018. The operation started in half of the year 2019.

Telecommunication Connection

Connection of the industrial zone was be ensured from the southeast part of the zone from existing cables laid along II/250 road and from the western part from the route running along the western edge of the central part of the Zone. The distribution frame as such was built by providers of telecommunication services on their own expenses as part of their telecommunication network (currently one provider is involved Česká telekomunikační infrastruktura a.s.).

Furthermore in the zone are available telecommunication and data connections of providers O2 Czech Republic a.s., T-Mobile Czech Republic a.s. and Vodafone Czech Republic a.s.


Connection of new investors will be negotiated individually with telephone network operator to arrange for separate  subscriber lines. Existing cable lines are owned by the providers. The Ústí Region is not involved in negotiations in respect of telephone connection.
