A new device was made to catch and receive surface runoff to sewerage system. The device increases wastewater flow and velocity in the wastewater networks which is provided by flushing and reducing decay of organic and inorganic substances in the networks.  

Keywords: Device, surface runoff, flow, flushing, siltation

Only innovative activity is able to unite all aspects of science, equipment, economy, business and management. The current state of the innovative sphere of Russia speaks about serious contradictions in its functioning. Considerable scientific and technical capacity of the country was lost in the period of economic reforms. Now often it is impossible to predict precisely succession of events in economic life of the country generally and each organization separately. In modern conditions scientific and technical progress represents innovative development which is defined by the state as the most important priority of economic policy. Innovative potential of any managing subject needs to be estimated as difficult social and institutional system. To encourage managers and the production personnel competently developed motivational strategy is necessary to conduct work on search of innovations. Achievement of the put indicators of innovative development of the Rostov region and the country as a whole has to become result of an offered method of interaction of science, business and authorities.

Keywords: innovative activity, scientific and technical potential, economy, business, ideas, effect, development

In conditions of reduction of the costs of wastewater actual value of the minimum speed and current case does not provide the required conditions of self-purification of networks. The studies conducted on the silt areas of current collectors of various diameters made of various materials with the purpose of determining the resistance of precipitation in the trays pipes.
Describes the methodology and instruments of research. The data obtained allowed with sufficient certainty have established roughness coefficient bottom sediments of sewers.   

Keywords: drainage network, the rate of self-purification, sewer, roughness, bottom sediments.

Recently, in the process of creating a single information space worsened organization relevant databases in geographically separated units of one company, no common local area network and to allow for working with databases via the Internet. The main solution is to organize the synchronization of electronic data on external media.
The developed application allows an automated procedure to find differences in the databases of reference materials and assortments, add to the database of any of the divisions of the elements that are missing from it, and are available in the other areas.
The present article is intended for those engaged in the organization of a common information space in the field of design and technological preparation of production through the creation and administration of topical databases.  

Keywords: database, reference of materials and assortments, algorithm, synchronization, program, enterprise
