Abstract
Kaliningrad is a large industrial city with the population more than 400 thousand people thathas no modem constructions for sewage treatment. Almost I 00 million m3 of sewage isannually discharged into the Pregolja River and the Vistula Lagoon. City authorities have aproject for constructing a full cycle of waste water treatment plant. However, the offereddevelopment plan and treatment level will not promote decreasing of eutrophication in theVistula Lagoon. In this article the opportunity of using water plants for additional cleaningsewage of Kaliningrad has being considered. For this purpose it is suggested to organize awetland park in a territory along the right bank of the Kaliningrad naval channel in an areawith 86.6 knl. The infrastructure for such wetland-park might be used for recreationalpurpose too. The proposal is to consider the wetland park as an effective commercialenterprise occupying certain sector in the economy of the city. The basic requirements toorganize the wetland park area are that: (I) The wetland-park area should be located nearbythe mechanical and biological sewage treatment; (2) Two zones should be created, anindustrial and a recreational zone; (3)The borders of zones should be separated by natural or artificial elements of landscape, forexample, forestations; (4) Economic and ecological requirements regarding the sewagemanagement in Kaliningrad city are related to the necessity of meeting the demands of theBaltic Region, in order to solve the environmental problems of the Baltic Sea.

The analysis of project which was made by a design institute "Lenvodokanalproyekt" showed that the period the construction will be completed the concentrations of the normalized substances in the water will comprise: 8OD5 - 8 mg/L; N - 10 mg/L; R - 1,5 mg/L, Municipal wastewater run out to river network and further to Vistula Lagoon, The quality ofwater in these water bodies is illustrated at the Table 3, Consequences anthropoge rnc eutro phication

Summary
The wetland-park can be created on the boggy grounds near to a site where new waste water treatment plant will be constructed. Wetland-park is a system ofartificial reservoirs and marsh sites, which serve for stabilization of physical properties and improvement of a chemical compound of sewage, which pass through a cycle of mechanical and biological treatment. This system is intended for restoration ofthese waters up to parameters ofecological full value ofthe natural not polluted waters. This system have elements, which will allow to use resources opportunities of these waters for an economic proposes, satisfaction of scientific, cultural, educational and aesthetic needs. Using this concept as a basis we shall consider the principal scheme of zoning of park's territory, which is submitted on Figure 2
