General description of the Project

The so called „black gold” of Latgale sapropel is an organic sediment in freshwater containers and is made from aquatic plants and animal residues, which are enriched by mineral particles. Sapropel contains many biologically active substances, such as vitamins, hormones, and it is applied in different sectors, for example, in agriculture, medicine, chemistry, construction material production, industry and elsewhere.

Perkonu lake depths were researched in the 80ies and it showed the amount and quality of sapropel, however such a study ought to be repeated. The provisions for the use of subterranean depths shall be determined by the Law on subterranean Depths in the municipality, and the binding regulations of the Cabinet.

Within the framework of the project it is planned to use the land area of 3.9 ha near the lake of Perkonu.

The lake is in the middle of a city which provides adequate infrastructure.
