Implementation pre-investment work on the development of urban sewage Andijan, Namangan and Fergana

Content

Conducted pre-investment studies and prepared relevant data on wastewater treatment plants for the cities. Andijan, Namangan and Fergana on:

1. Basic information:

The number of people currently connected to the sewage network, which delivers wastewater on CBS, at the present time, in the medium term (5 years) and long-term (10 years)

2. Characteristics ofsewarage network:

• combined and separate
• location area of the city and points of entry and exit networks;
• type of pipes (self-flowing and pressure)
• the volume of wastewater main customers with the corresponding data;
• characteristics effluent (water) (oxygen content, the saturation substances, acidity, the presence of nitrogen, phosphorus, coli index)
• type of disposal of sewage sludge (compost, burial, incineration);

3. The development of sewerage:

• the general plan of the existing wastewater treatment plants. Also give the site plan, which may be expansion of the existing station.
• the geological and geotechnical characteristics of the site;
• the mechanical properties and bearing capacity of the soil ( kg/ cм²)
• geotechnical investigations for geotechnical site characteristics (the wells)
• development plans, the quality of roads, the distance from the main roads, etc.
• power supply: Voltage (V) Net power (kVA), distance to the nearest point of connection to the high voltage network.
• availability of drinking water on site: Available flow and pressure, the point of connection.
