This book was released on 2015 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Substantial savings in operations can be achieved by reducing the amount of wastewater that must be pumped and treated. Utilities have long dealt with the infiltration and inflow (I and I) issues in their system by televising their pipes and identifying leak points, but this primarily addresses only the infiltration part of "I and I." Inflow, which creates hydraulic issues during rain events, leads to sanitary sewer overflows and can subject the utility to fines from regulatory agencies. As a result, dealing with the inflow portion of I and I is needed. The goal of this thesis is to differentiate inflow and infiltration from baseflow and to determine the effectiveness of different methods used to reduce inflow and infiltration in sanitary sewer lines. An analysis was conducted on the benefits and cost effectiveness of different inflow/infiltration approaches (slip-lining sewer lines, stormwater manhole inserts, replacing sewer lines, smoke testing, etc.) and cost savings municipalities can expect to receive from each. Unlike most other studies, which identify rainfall derived inflow and infiltration (RDII), the goal of this study was to develop a means to separate the flows into inflow, infiltration and baseflow. It was assumed that inflow into sanitary sewer lines is linearly related to rainfall and infiltration is linearly related to groundwater elevation. Based on these assumptions, inflow and infiltration could each be separated out from the wastewater flow, leaving only baseflow. Once the inflow and infiltration have been separated from the flows, pre and post flows could be compared to determine a percent reduction in both to develop a cost analysis. The conclusions developed from this project are directly related to the method for determining the inflow and infiltration reduction, which were related to rainfall and groundwater elevation, respectively. It was shown that inflow is directly related to rainfall, and infiltration (excluding inflow) is directly related to groundwater elevations. The results of the analysis showed that inflow and infiltration correction methods were effective in removing significant amounts of inflow and infiltration from the sanitary sewer system. However, when compared to the cost to complete the construction activities, it was evident that inflow reduction was much more cost effective.

Book Synopsis Assessing Infiltration and Exfiltration on the Performance of Urban Sewer Systems by : Bryan Ellis
Download or read book Assessing Infiltration and Exfiltration on the Performance of Urban Sewer Systems written by Bryan Ellis and published by IWA Publishing. This book was released on 2010-02-10 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sewer systems constitute a very significant heritage in European cities. Their structural quality and functional efficiency are key parameters to guarantee the transfer of domestic and industrial wastewater to treatment plants without infiltration nor exfiltration. Infiltration of groundwater is particularly detrimental to treatment plant efficiency, while exfiltration of wastewater can lead to groundwater contamination. The European research project APUSS (Assessing infiltration and exfiltration on the Performance of Urban Sewer Systems) was devoted to sewer infiltration and exfiltration questions. It was structured in three main Work Areas dealing respectively with i) the development of new measurement methods based on tracer experiments and accounting for detailed uncertainty analyses, ii) the implementation of models and software tools to integrate structural and experimental data and to facilitate data display, operational management and decision-making processes and iii) the integration of economic and operational questions by means of cost estimation, economic evaluation, performance indicators and multi-criteria methods applied to investment/rehabilitation strategies. This final report describes the objectives, methods and main results for each Work Area. References to detailed methods, protocols, reports and tools are given in this final report which will be an invaluable source of information for all those concerned with the performance of urban sewer systems.

Download or read book Sewer System Evaluation for Infiltration Inflow written by U.S. Environmental Protection Agency and published by BiblioGov. This book was released on 2013-11 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Environmental Protection Agency (EPA) was introduced on December 2, 1970 by President Richard Nixon. The agency is charged with protecting human health and the environment, by writing and enforcing regulations based on laws passed by Congress. The EPA's struggle to protect health and the environment is seen through each of its official publications. These publications outline new policies, detail problems with enforcing laws, document the need for new legislation, and describe new tactics to use to solve these issues. This collection of publications ranges from historic documents to reports released in the new millennium, and features works like: Bicycle for a Better Environment, Health Effects of Increasing Sulfur Oxides Emissions Draft, and Women and Environmental Health.
