Analysis of factors producing an effect on the integrity and environmental safety of water distribution networks

Summary

The environmentally safe construction and operation of public utilities facilitates to a large extent the sustainable deve­lopment of cities and communities. Pipelines of a water distribution network can be referred to the basic elements of the municipal water supply system and, as operational practice shows, are most vulnerable. Transition to market economy, reforming housing and public utilities under conditions of wear and aging of engineering life support systems of the Russian cities and communities, lack of material and financial resources for their renovation have significantly exacerbated the ecological situation in the country. Unsatisfactory condition of the water supplying pipelines in most of the cities, imperfect operation management result in numerous pipeline failures and, consequently, in material and environmental damages caused by the changing hydrogeological territorial regime, underflooding, raw wastewater discharge into water bodies and surface spills, increased soil corrosiveness etc. In that context supplying the population with sufficient amount of drinking water of the required quality and environmental safety of water use have been most urgent issues in Russia. The integrity and environmental safety have been the main requirements set to the public water supply pipelines. The results of studying the assessment and analysis of the factors effecting the integrity and environmental safety of the water distribution pipelines are presented. The assessment and analysis of the external factors (parameters, characteristics) that can produce a significant effect on both the pipe integrity and environmental safety and their efficient lifetime are the basis of developing the measures on improving the reliability of the municipal water distribution pipelines.

On designing water supply schemes of the Russian cities

Summary

The summary on the water supply conditions in the country is presented. Supplying the population with sufficient amount of drinking water of the required quality and environmental safety of water use have been very important issues in Russia that differ for different regions and population groups. In general it is related not only to the replacement of the outdated equipment and elimination of the general technical backwardness, but in the first place to the need to solve legal, organizational and economic problems. To provide for the stepwise implementation of the set tasks of upgrading and reconstructing municipal water supply and wastewater disposal systems in Russia as well as for the economic encouragement of their development the RF Government approved and put into effect the new regulatory documents – Federal Law of December 7, 2011 No. 416-FZ «On water supply and wastewater management» and «Regulations for development and approval of water and wastewater management schemes and requirements to their maintenance». The guidance issues of designing municipal and communal water supply schemes by the example of Ufa and Irkutsk are considered. The sections to be included into the municipal water supply schemes alongside with the principles of supplying drinking water to the population of certain municipal entities are presented. Successful designing regional water supply schemes is ensured by the availability of the background information on the technical condition of the system; water intake conformance to the project water demand; hydrogeolical survey and confirmed operating inventory of the potential reserve water sources; availability of the master plans of territorial development.

Specific features of collection and treatment of industrial stormwater runoff from motor transport enterprises

Summary

The urgency of the problem of industrial stormwater runoff collection and treatment has been caused by the continuous car density growth that is a high-toxic pollution source. The task of the studies was investigation and assessment of the motor transport enterprise impact on the municipal watershed health under current conditions. The results of inspecting water utilization schemes at motor transport enterprises, bus, trolley-bus and taxi depots, truck depots, motor pools of construction equipment, road machinery and specialty vehicles are presented. Core process flows: engine, radiator and machine battery part washing, fuel tank testing, parts and assemblies washing, outside washing and painting of motor vehicles were investigated. Full-scale inspection of local intrashop wastewater treatment facilities and intrasite surface runoff facilities was carried out; laboratory analyses of raw wastewater and effluent quantitative and qualitative parameters including oil products, suspended solids, salt content, synthetic surfactants, heavy metals etc. were made. Rational technical solutions for improving the operation of industrial stormwater runoff treatment facilities with the use of mechanical, physical and chemical treatment technologies including horizontal grit chambers, settlers-oil separators, pressure filter cascade with mineral granular media and high efficient sorption materials were suggested. At that, the efficiency of treatment meets the effluent requirements for being reused as process water or discharged into the municipal storm collector and water bodies.

Advanced technologies of municipal waste management

Summary

The living activity of a modern city is accompanied by the generation of big waste amounts. In the current situation an important task of the municipal utilities is providing for the environmentally safe and energy efficient waste management. Most commonly used advanced technologies of municipal waste management – solid wastes and wastewater sludge – are presented. The options of implementing the mentioned technologies are considered; the information on the implemented projects of new generation facilities for solid waste and wastewater sludge processing and utilization designed by «MosvodokanalNIIproject» OJSC is given. Minimization of the negative impact of waste disposal on the environmental and public health is provided only by waste landfilling with the use of eco-technologies and environmental protection facilities. Thermal solid waste and wastewater sludge processing (incineration) at special boiler plants with generation of heat and electricity is an optimal option of waste disposal for the municipal utilities since it provides for the simultaneous utilization of solid by-products of incineration. On the basis of the long experience of «MosvodokanalNIIproject» OJSC in the field of designing and commissioning the facilities for waste collection, processing and utilization it is shown that environmentally sound utilization can be ensured only by using advanced waste treatment technologies that provide for environmentally safe storage, processing and disposal; reducing waste amount subject to landfilling; increasing the amount of recyclable materials and waste energy use.
