Problems and risks of sanitation in abo qir february 2013 
Elements of the Problem:
1- Direct Industrial wastewater disposal into water bodies (Abo Qir bay, Amia drain and Tabia).
2- Deterioration of Public sewerage system.
3 -Vertical and horizontal housing extensions in random areas.
4 - Increasing levels of groundwater
02 pipe networks
The document discusses pipe networks for water distribution systems. It describes:
1) Pipe networks can have multiple sources and sinks connected by an interconnected network of pipes. Computer solutions are used to model pipe networks.
2) Assumptions made in modeling pipe networks include each point having a single pressure and equal pressure changes along parallel paths. Conservation of mass is assumed at nodes.
3) Pipes can be modeled in parallel by applying the energy equation between nodes and adding pipe flows. Computer solutions are needed for networks with multiple loops.
Sewerage network
This document provides an introduction to sewerage network design. It defines key terms like sewage, sewer, and sewerage. It outlines information required for design like design criteria, master plan layout, and levels. Design criteria includes parameters like sewage generation rates, minimum velocities and slopes, peaking factors, and pipe materials. The design process involves marking the network on a layout, calculating population, hydraulic design, and producing final drawings.

This document provides an overview of a training course on waste water sampling and analysis. It discusses different types of pollutants found in domestic and industrial wastewater, including organic compounds that consume oxygen during biological breakdown. Pathogens that can be transmitted through wastewater are described, such as bacteria (e.g. fecal coliform), parasites (e.g. Giardia lamblia), and helminths (parasitic worm eggs). Common waterborne diseases are listed including typhoid, hepatitis A, and amebiasis. Details are given about indicator bacteria tested for in wastewater analysis such as fecal coliform and E. coli, which indicate fecal contamination.
materials of sewer
The document discusses various materials used for sewer construction including brick, concrete, precast concrete, cast-in-situ concrete, stoneware, asbestos cement, cast iron, steel, ductile iron, UPVC, HDPE, GRP, FRP and pitch fibre pipes. For each material, the key advantages and disadvantages are described. The document also provides the relevant Indian Standard specifications for each material. Crown corrosion of concrete sewers is explained as being caused by the formation of sulfuric acid due to the action of sulfate reducing bacteria on hydrogen sulfide gas in stagnant sewage flow at the bottom of sewers.

Water distribution system design report
This document presents the final report for the water distribution system design of the Future Vision Housing Society located near Jehlum Road in Lahore, Pakistan. It includes the design criteria, assumptions, and completed design of the water distribution piping network using the Loop software program. The network consists of 23 nodes, 30 pipes of varying diameters from 80mm to 500mm, and is fed by two tube wells with water stored in an overhead reservoir 20 meters high. The report provides all relevant input data and output results from the hydraulic analysis of the piped network.

sewers and sewer netwrok - design construction and maintenance
This document discusses the design of sewer systems. It begins by classifying sewers into domestic, storm, and combined sewers based on what they are designed to carry. It notes the advantages and disadvantages of combined sewers. The document then discusses methods for estimating sewage flow rates, including population forecasting, per capita flow rates, and peak flow factors. It also covers stormwater runoff estimation and the rational method formula. Finally, it discusses some hydraulic design considerations for sewers, such as designing for partial flow rather than full flow due to gas generation in sewers.
Sewerage design
This document discusses the design considerations for sewer systems. It outlines the different types of sewers based on wastewater flow, and specifies design requirements like pipe sizing, slopes, depths, and velocities. Factors like population equivalent calculations, peak flows, hydraulic properties, and manhole levels are also summarized. The document provides guidance on planning and laying out sewer networks in accordance with relevant codes and standards.
Hydraulic design of sewer
Hydraulic Design of Sewer:
Hydraulic formulae, maximum and minimum velocities in sewer, hydraulic
characteristics of circular sewer in running full and partial full conditions,
laying and testing of sewer, sewer appurtenances and network.

Various types of HVAC installations and systems are covered, like central air, zoned heating, and radiant heat. Recent developments in HVAC technology and applications are also summarized along with the advantages and disadvantages of HVAC.
Sewage treatment plant design calculation
1) The document outlines the design calculations for a sewage treatment plant for a mixed development project with 40 residential units and 18 commercial units. The population equivalent is calculated to be 293.
2) A rotating biological contractor (RBC) system is selected as the sewage treatment method since it is suitable for staged development, requires low land area, produces high quality effluent, and has low operation and maintenance costs.
3) Design parameters for the sewer reticulation pipes are provided, including a peak flow factor calculation, minimum pipe sizes and slopes, maximum infiltration rates, and manhole specifications such as location, depth, and gradient requirements.
Pipe network analysis with examples
(1) The document discusses water supply distribution networks and their components. It describes various natural and non-traditional water sources, as well as water quality parameters and treatment methods.
(2) Distribution networks use reservoirs, transmission pipelines, and distribution mains to deliver water from treatment plants to consumers. The document discusses different network layouts and design considerations like minimizing dead ends.
(3) Pipe network analysis methods like Hardy-Cross and nodal methods are presented to calculate pipe flows and node pressures. An example applies Hardy-Cross iteration to determine flows in a pipe loop that balances the head loss around the loop.
