Anti-seepage means for protective embankment of Kariotiškes sewage sludge dump

Abstract

The seepage through the protective embankment of the Kariotiskes sewage sludge dump and anti-seepage means for the stopping of seepage are analysed in the article. It was determined that during the closure works of the dump of Kariotiskes it is necessary to ensure (due to the environmental protection requirements) that sludge filtrate should not filtrate through the protective embankment and should not gain access into the surroundings. Having viewed all possible anti-seepage means (drainage, changing of permeable soils into impermeable ones, etc.) as well as the geological situation we came to the conclusion that one of the most effective, economic and simplest ways was the arrangement of hermetic sheet piling
