There are about 130 filter wells by means of a suspension of lignite filter ash and water (about 1 400 m 3 ) to keep. The fountain sites are, if not recognizable locally, staked. Preparatory logging and clearing work totaling 12 ha. At the same time, the surrounding areas are cleared of mining-typical facilities (including dismantling of overhead line installations, mast shoes, condensers, pipeline residues, e-cabinets of filter wells).

- On approx. 12 ha preparatory wood cutting / clearing,

- to approx. 3,500 m dismantling / disposal of the discharge systems (pipelines) of the former filter well bolts,

- approx. 33 t disposal of iron hydroxide sludge (from the pipelines),

- approx. 3,700 m depth of the exploratory offset drill holes,

- deliver approx. 2 500 t lignite filter bag,

- about 1 600 m 3 Introduce offsetting suspension,

- About 1 100 m 2 Lay geogrids to secure well locations.

Dismantling of overhead lines:

- about 140 m 3 Underfloor demolition reinforced concrete former mast foundations,

- Approx. 2,000 t of demolition / disposal shaft construction concrete and masonry.
