Extending Budapest’s sewer system to unconnected districts
The extension of Budapest’s sewer system to some previously unconnected districts leads to better health and quality-of-life for thousands of residents.
Some of Budapest’s districts are unconnected to the city’s main sewer system. An EU-funded project extends wastewater services to these districts by connecting up to 20 522 households – covering 43 500 residents – to the public sewage system. It ensures that their wastewater is collected and treated, improving life and the environment in the Hungarian capital.
In Budaörs, part of Budapest’s metropolitan area, the old wastewater treatment plant serving the municipality is being closed. Budaörs’ sewers will be connected to Budapest's system. No new wastewater treatment plant will be constructed. Budapest’s north, south and central wastewater treatment plants have enough spare capacity to treat the additional loads from the newly connected districts of Budapest and from Budaörs.
The project creates 300 jobs during the implementation phase and 10 in its operational phase. The project is partially self-financing: it will generate net revenue from sewer fees.
By the end of the project, a total 258 km of sewers will have been constructed. The work includes two new main collectors from Budaörs and South Buda, river crossings under the Danube, and 237.5 km of small diameter pipes. Altogether, 19 pumping stations, up to 450 domestic pumping stations, and 9 individual facilities or pits are being constructed or refurbished.
Implementation has been divided into two phases, both of which are technically interconnected. The second phase is due to be completed by the end of 2016.
Of the 231.6 km of sewer connections to be built in the first phase, 375 m concern water-flow regulation elements and 13.9 km involve main network sections. The remaining 217.3 km of sewers correspond to 14 049 domestic connections and will be implemented in districts 2, 3, 4, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 22 and 23.
The most significant network development, amounting to almost 80 % of the total length of the first phase, will be carried out in district 18, where 88 726 m of sewers will be constructed; in district 22 (34 364 m of sewers); district 3 (18 855 m of sewers); district 16 (16 064 m of sewers); and district 17 (15 053 m of sewers). In the first phase, 14 pumping stations will be reconstructed, 4 new pumping stations will be built and an additional 450 small domestic pumping stations will be implemented.
During this phase, flow regulation elements will be constructed to transfer the wastewater between treatment plants. The diverting structures are being constructed at Éles sarok (district 10). The 375 m sewer section connected to these structures will transfer wastewater from the catchment area of the Central Wastewater Treatment Plant to the North Pest Wastewater Treatment Plant.
In the second phase, 1 100 additional connections will be made and 26.5 km of sewers will be built in various districts of Budapest. One more new pumping station for Budaörs main collector will be constructed. Phase two also involves the construction of a 4 573 m long main collector for Budaörs and a 1 790 m stretch finishing part of the South Buda main collector.
Main collectors, river crossings
The project implements two main collectors and river crossings under the Danube. The first phase covers the construction of 13 223 m from the South Buda main collector and 640 m of river crossings. In the second phase, construction will involve a small part of South Buda’s main collector, the 1 790 m section at Váza street’s pumping station, as well as 4 573 m of Budaörs’ other main collector.
