The permeability of the Upper Pannonian reservoir, in case of highly permeable sand layers, in the Hodmezovasarhely region can reach 2000 mD; this corresponds to a hydraulic conductivity of 5-10 m/day .
Hodmezovasarhely, located in the Southern Great Plain of Hungary, has one of the oldest operating geothermal systems in Central Europe (the first well was drilled in 1957), where the cascade system is supplying domestic hot water and heat to 3000 flats and several large communal buildings (city hall, schools, high schools, libraries, swimming pools and sport halls, etc.).
In our research, two independent reinjection systems were studied as the part of the low temperature geothermal system in the city of Hodmezovasarhely. The surface elements of the reinjection system clogged much faster in case of the reinjection system number 2.

I was pleasantly surprised at how adequately the announcer pronounces the names of such Hungarian cities as Hodmezovasarhely
or Nyiregyhaza in Bookshelf '93, and it is impressive that Microsoft hired native speakers to record a few greetings and proverbs for many of the country entries in Encarta.
