The stream, which will be discussed in this article, is the right tributary of the Okhta River, which flows in the city of St. Petersburg. The beginning of this small stream takes in the forest park "Sosnovka". He received his name from the name of the village of Murino located not far from him.
Later in the article we will give more detailed information about the Murinsky stream.
History
Quite interesting historical facts about these places. Back in the 60s of the 20th century, mass housing construction began in the area of the described stream. In the 70s, this reservoir began to represent the border between two areas of new buildings: the GDR (this is the newest area, located on the left bank and called Grazhdanka beyond the stream), the FRG (the right bank is the fashionable Grazhdanka district).
In 1980, it was decided to create a green recreation area in the floodplain of the stream, but these plans for a long time remained only on paper. Only at the beginning of the 2000s did active work begin on the reclamation of land and the stream bed. As a result, the first park areas were created in the upper reaches (in the area west of Svetlanovsky Prospekt).
And nowthere are grandiose projects to create a park in this place. Murinsky stream should become a place of rest for numerous citizens and guests of the capital. It is planned to place various attractions, a cafe, a cultural center with a cinema, a hotel, sports areas and an outdoor pool with a water heating system, operating at any time of the year.
Geographic location of the stream, description
Murinsky Creek (St. Petersburg) flows to the east and flows into the Okhta River (right tributary) near the village of Novaya. It has a length of 8.7 kilometers, a width of 5 to 30 meters, and its depth reaches an average of 1 meter (up to 2-3 meters in ponds). The total area of the pool is approximately 41 sq. kilometer.
By the way, roach, perch, pike and crucian carp are found in some of its ponds.
Environmental Issues
Unfortunately, the ecology of the stream has been seriously affected due to the massive development of these places and, accordingly, with an increase in discharges of untreated sewage. The stream (especially its lower and middle course) for several decades practically turned into a fetid channel. Environmental problems sometimes arise in its upper reaches. For example, in 2010, sewer drains broke through in the spring, after which an unauthorized tie-in into the collector was discovered. Subsequently, this caused the death of many fish and stopped nesting on the banks of the bird stream.
In fact, this stream is practically the only open sewerage left in St. Petersburg, carrying its dirty waters to the Okhta River,which then flow into the Neva. Such circumstances are explained by the lack of money for the creation of modern treatment facilities.
Other sources of pollution
Sources of pollution of the Murinsky stream are:
- stormwater urban runoff (from transport highways and from container sites, in the amount of about 140, in the area of the Parnassus industrial zone);
- switching household wastewater from residential buildings to the storm sewer network (emergency situations, erroneous connections during the construction of new houses, unauthorized creation of jumpers inside residential quarters);
- numerous sewage discharges from an emergency outlet during various works on the Vyborgsky collector tunnel to prevent flooding of this large part of the city.
All these factors led to a rather unsatisfactory, or rather, catastrophic sanitary and epidemiological situation in the Kalininsky district of St. Petersburg.
About the composition of water
The water in the middle part and in the lower reaches of the described stream is muddy, its transparency is 4 centimeters. The smell of fecal reaches up to 5 points. The content of oil products is up to 7 mg per liter, iron - 4.4 mg per liter, surfactants - 1.3 mg per liter. The sediment of the bottom of the reservoir is black, silty, with the presence of the smell of decay, the channel is swampy.
Almost all samples taken after laboratory tests showed a discrepancy between the composition of water and sanitary standards in terms of bacteriological indicators(studies in 2000-2001), pathogenic microflora was also found. Thus, the degree of pollution of the watercourse of the stream is assessed as high.
And today the Murinsky stream is experiencing intense pollution, confirmed by the data of periodic laboratory water tests.
It should be noted that above the dam (near Svetlanovsky Avenue) and at the source of the stream, where there are no above-mentioned harmful drains and where the floodplain is landscaped, the water is clear and clean.
In conclusion about future plans
At the very source of the Murinsky Creek, there was once a Benois farm, as well as the avenue of the same name (now it is Tikhoretsky). This farm was later merged with another small one located on the opposite side of the stream. Today, the city administration and investors are working on the restoration of this farm and the park adjacent to it.
It is planned to build an urban amusement park on this site, which will be connected to the park at the top of the stream.
