Description

Recently, a number of sites in the target area suffer from heavy local rainfall that cause threats to private and public properties. The aim of the project is to stabilize the water management in the target area and to prevent risks of floods by directing the rainwater and surface water. The objective is to increase the water retention in the countryside in the project area. Water retention measures which will be proposed and implemented within the project area have to meet and ensure the safety of the protected area and focus on the risk management of human settlements. Two project partners are involved in the implementation of the project, the village af Sirnik and the village of Hran.

Summary of project results

Due to the climate change, the territory in question suffers from a high intensity rainfall leading to local flash floods. The municipalities Borša and Viničky are protected from a high water level, caused by near river Bodrog, by dams. On the other hand, outlets collecting water from the protected landscape must be closed if the water level in the river is too high. This unables the water collected in the protected landscape to escape from the territory to the Bodrog river. The solution was to build stations where, if needed, mobile pumping stations can be established. It was also necessary to enforce the dam and to build a road for the trucks to be able to deliver the mobile aggregates. 6 pcs of mobile pumps are possible to establish on the spots of the original dam outlets. Outlets equipped by metal flaps. Kamenná Moľva and Ladislav pumping station transport the rain water caught in the landscape of Ondava left riverbank back to the river. This situation occurs in spring months or during intensive rainfall (territory of 8 250 ha-the gravitational outflow is not sufficient). Pumps are wearing out after 20 years; operation was not possible without manpower. For reliable function overall reconstruction was necessary. The technology reconstruction of K. Moľva pumping station consists mainly of: 4 main pumps replaced, 3 additional pumps replaced, 4 pcs of outlet flaps replaced at the end of the pipelines, electrification and renovation of the flaps (DN 1200), electricity network reconstruction, new automation, signalization and measurement system. The technology reconstruction of Ladislav pumping station consists mainly of: 3 main pumps replaced (DN 1000 Q= 1300 dm3/s), 2 additional pumps replaced (DN 700 q= 500 dm3/s) and 2 additional (supporting) pumps replaced (DN 700 q= 300 dm3/s), reconstruction of the building and air-conditioning, pumping station surrounding area treatment and new automation, signalization and measurement system. The municipality of Sirník – construction of 2 water retention reservoirs was done in order to increase the landscape water retention capacity (increase of 16 020 m3). 3 new canals were build (197,2 m), surrounding area treatment (trees planted) and road for reservoirs maintenance was build. The municipality of Hraň – rainwater from the populated area is taken by gravity to the landscape lowest point from where it can be pumped into the Trnávka river. New canals were build, automated pumping station including 2 pumps (2x 60m3/hour), power inlet, outlet pipeline (DN 300 mm) build through the dam into Trnávka river.
