Flood retention basin to be expanded – Orosháza is also preparing to manage flash floods

The public procurement procedure has been finalised, and the works contract has been signed. Under this contract, the capacity of the stormwater retention basin in the Dr László Elek housing estate in Orosháza will be expanded, the open channels will be renovated, and the necessary backflow prevention elements will be installed.

Construction will take place at eight sites

The contract was awarded to the Békéscsaba-based „KOPP” Export-Import Kft.. The work will need to be carried out at several locations across the town; the areas affected by the works include:
Keleti-övárok, CS-2-0 (between Liliom and Székely streets) — Szulalaposi Canal, CS-1-0 (between Bajcsy and Makói streets) — Csengeri Street – the Dr László Elek housing estate stormwater retention basin and its catchment area, as well as the sections of Könd, Bajnok, Kórház and Csendes streets between Zombai and Oláh streets.

The aim is to retain the water on site

As part of the project, the rainwater drainage system will be upgraded along a total of 5,584 metres. On the earth-filled section of the Keleti-övárok between Liliom Street and Székely Street, the base and slopes will be reinforced using concrete elements and concrete elements with drainage holes. These solutions will simultaneously help to retain and drain rainwater on site, as well as to drain off excess water.

A section of sewer is being built along a new route

On the Szulalaposi Canal, in addition to the renovation of the existing open-channel watercourse, the route will also need to be re-routed. On the section between Bajcsy-Zsilinszky Street and Makói Road, the canal will be relocated from the area of the Orosháza–Mezőhegyes railway line, and the original route will be restored by backfilling.

The reservoir’s capacity is to be increased to 8,600 cubic metres

Significant work is also taking place in the area of the Dr László Elek housing estate. The capacity of the existing stormwater retention basin is being expanded: the basin will be deepened by 2 metres, and its planned volume will be 8,600 cubic metres. The aim of the development is to enable rainwater from a larger part of the housing estate and its catchment area to be channelled into the reservoir, thereby relieving the burden on the surrounding rainwater drainage systems.
