Civil Engineering Mini Project For 7th Semester Students Of Anna University: A Mini Guide

Reached almost your final semester? What else there for you to face. Yes still there is a thing that you need to face. That is you seventh semester project. What are the difficulties in it. Here I"m gonna explain you the things that you really need to follow to grab good grade. When it comes to project, you should have clear idea about your project. Even if you did"nt take part with your team, please be aware of what they are doing. Ask them and have an detail idea. Viva voice will be mostly from your project book and be ready to face. Conduct viva by your self with your team mets otherwise you will be the sufferer.

No need to take paper presentation but in rare case, you would be asked to do that. If so, be bold in your talk. I'm bit calm person but I strongly suggest you to be bold. At the same time be humble in front of external examiner. Don't try to show that you only did everthing on your project and make your batchmet fool. That's strictly a mad activity. Give chance to your batchmet. Most probably, marks for the each member would be same. This is because, external might try to give worth to your team effort.

I have many tips with me especially for civil Engineering students. If you need me to tell more then please leave your comment. I will consider your need and try to publish many tips in this site which is totally dedicated for education. We would like to hear from you especially from civil Engineering students. Thanks a lot and take care

Cellulose acetate membranes can be degraded by microbiological activity. Proper maintenance of chlorine residuals can prevent microbiological attack of these membranes.

Polyacrylamide membranes are resistant to microbiological degradation; however, they are susceptible to chemical oxidation. Therefore, chlorination is not an acceptable treatment. If inoculation occurs, microbiological fouling can become a problem. Nonoxidizing antimicrobials and biodispersants should be used if serious microbiological fouling potential exists

CE2304 Environmental engineering-I QUESTION BANK Innovative approaches

A number of innovative approaches to improve water supply and sanitation have been tested in India, in particular in the early 2000s. These include community-led total sanitation, demand-driven approaches in rural water supply, a public-private partnerships to improve the continuity of urban water supply in Karnataka, and the use of micro-credit to women in order to improve access to water.
Community-led total sanitation
In 1999 a demand-driven and people-centered sanitation program was initiated under the name Total Sanitation Campaign (TSC) or Community-led total sanitation. It evolved from the limited achievements of the first structured programme for rural sanitation in India, the Central Rural Sanitation Programme, which had minimal community participation. Community-led total sanitation is not focused on building infrastructure, but on preventing open defecation through peer pressure and shame. In Maharashtra where the program started more than 2000 Gram Panchayats have achieved "open defecation free" status. Villages that achieve this status receive monetary rewards and high publicity under a program called Nirmal Gram Puraskar.[36][37][38]
Demand-driven approaches in rural water supply
Most rural water supply schemes in India use a centralized, supply-driven approach, i.e. a government institution designs a project and has it built with little community consultation and no capacity building for the community, often requiring no water fees to be paid for its subsequent operation. Since 2002 the Government of India has rolled out at the national level a program to change the way in which water and sanitation services are supported in rural areas. The program, called Swajaldhara, decentralizes service delivery responsibility to rural local governments and user groups. Under the new approach communities are being consulted and trained, and users agree up-front to pay a tariff that is set at a level sufficiently high to cover operation and maintenance costs. It also includes measures to promote sanitation and to improve hygiene behavior. The national program follows a pilot program launched in 1999.
According to a 2008 World Bank study in 10 Indian states, Swajaldhara results in lower capital costs, lower administrative costs and better service quality compared to the supply-driven approach. In particular, the study found that the average full cost of supply-driven schemes is 38 (US$0.8) per cubic meter, while it is only 26 (US$0.6) per cubic meter for demand-driven schemes. These costs include capital, operation and maintenance costs, administrative costs and coping costs incurred by users of malfunctioning systems. Coping costs include traveling long distances to obtain water, standing in long queues, storing water and repairing failed systems. Among the surveyed systems that were built using supply-driven approach system breakdowns were common, the quantity and quality of water supply were less than foreseen in designs, and 30% of households did not get daily supply in summer. The poor functioning of one system sometimes leads to the construction of another system, so that about 30% of households surveyed were served by several systems. Currently only about 10% of rural water schemes built in India use a demand-driven approach. Since water users have to pay lower or no tariffs under the supply-driven approach, this discourages them to opt for a demand-driven approach, even if the likelihood of the systems operating on a sustainable basis is higher under a demand-driven approach

CE2304 Environmental engineering-I QUESTION BANK Private sector participation

Private sector participation:

The private sector plays a limited, albeit recently increasing role in operating and maintaining urban water systems on behalf of ULBs. For example, the Jamshedpur Utilities & Services Company (Jusco), a subsidiary of Tata Steel, has a lease contract for Jamshedpur(Jharkhand), a management contract in Haldia(West Bengal), another contract in Mysore(Karnataka) and since 2007 a contract for the reduction of non-revenue water in parts of Bhopal (Madhya Pradhesh).[29] The French water company Veolia won a management contract in three cities in Karnataka in 2005.[30][31][32] In 2002 a consortium including Thames Water won a pilot contract covering 40,000 households to reduce non-revenue water in parts of Bangalore, funded by the Japan Bank for International Cooperation. The contract was scaled up in 2004.[33] The Cypriot company Hydro-Comp, together with two Indian companies, won a 10-year concession contract for the city of Latur City (Maharashtra) in 2007 and an operator-consultant contract in Madurai (Tamil Nadu).[34] Furthermore, the private Indian infrastructure development company SPML is engaged in Build-Operate-Transfer (BOT) projects, such as a bulk water supply project for Bhiwandi (Maharashtra

Environmental engineering-I question bank : Service quality

Service quality
Water and sanitation service quality in India is generally poor, although there has been some limited progress concerning continuity of supply in urban areas and access to sanitation in rural areas.
Water supply.
Challenges. None of the 35 Indian cities with a population of more than one million distribute water for more than a few hours per day, despite generally sufficient infrastructure. Owing to inadequate pressure people struggle to collect water even when it is available. According to the World Bank, none have performance indicators that compare with average international standards.[8] A 2007 study by the Asian Development Bank showed that in 20 cities the average duration of supply was only 4.3 hours per day. No city had continuous supply. The longest duration of supply was 12 hours per day in Chandigarh, and the lowest was 0.3 hours per day in Rajkot.[3] In Delhi residents receive water only a few hours per day because of inadequate management of the distribution system. This results in contaminated water and forces households to complement a deficient public water service at prohibitive 'coping' costs; the poor suffer most from this situation. For example, according to a 1996 survey households in Delhi spent an average of 2,182 (US$48.4) per year in time and money to cope with poor service levels.[9] This is more than three times as much as the 2001 water bill of about US$18 per year of a Delhi household that uses 20 cubic meters per month.
Achievements. Jamshedpur, a city in Jharkhand with 573,000 inhabitants, provided 25% of its residents with continuous water supply in 2009.Navi Mumbai, a planned city with more than 1m inhabitants, has achieved continuous supply for about half its population as of January 2009.[11] Badlapur, another city in the Mumbai Conurbation with a population of 140,000, has achieved continuous supply in 3 out of 10 operating zones, covering 30% of its population.Thiruvananthapuram, the capital of Kerala state with a population of 745,000 in 2001, is probably the largest Indian city that enjoys continuous water supply.
Sanitation
Most Indians depend on on-site sanitation facilities. Recently, access to on-site sanitation have increased in both rural and urban areas. In rural areas, total sanitation has been successful (see below). In urban areas, a good practice is the Slum Sanitation Program in Mumbai that has provided access to sanitation for a quarter million slum dwellers. Sewerage, where available, is often in a bad state. In Delhi the sewerage network has lacked maintenance over the years and overflow of raw sewage in open drains is common, due to blockage, settlements and inadequate pumping capacities. The capacity of the 17 existing wastewater treatment plants in Delhi is adequate to cater a daily production of waste water of less than 50% of the drinking water produced.[8] Of the 2.5 Billion people in the world that defecate openly, some 665 million live in India. This is of greater concern as 88% of deaths from diarrhea occur because of unsafe water, inadequate sanitation and poor hygiene.[15][16][17][18]
Environment
Millions depend on the polluted Ganges river.
See also: Environment of India
As of 2003, it was estimated that only 27% of India's wastewater was being treated, with the remainder flowing into rivers, canals, groundwater or the sea.,[4][19] For example, the sacred Ganges river is infested with diseases and in some places "the Ganges becomes black and septic. Corpses, of semi-cremated adults or enshrouded babies, drift slowly by.".[18] NewsWeek describes Delhi's sacred Yamuna River as "a putrid ribbon of black sludge" where fecal bacteria is 10,000 over safety limits despite a 15-year program to address the problem.[20] Cholera epidemics are not unknown.[20]
Health impact
The lack of adequate sanitation and safe water has significant negative health impacts including diarrhea, referred to by travelers as the "Delhi Belly",[21] and experienced by about 10 million visitors annually.[22] While most visitors to India recover quickly and otherwise receive proper care, the World Health Organisation estimated that around 700,000 Indians die each year from diarrhea.[19] The dismal working conditions of sewer workers are another concern. A survey of the working conditions of sewage workers in Delhi showed that most of them suffer from chronic diseases, respiratory problems, skin disorders, allergies, headaches and eye infections.[23]
Water supply and water resources
Depleting ground water table and deteriorating ground water quality are threatening the sustainability of both urban and rural water supply in many parts of India. The supply of cities that depend on surface water is threatened by pollution, increasing water scarcity and conflicts among users. For example, Bangalore depends to a large extent on water pumped since 1974 from the Kaveri river, whose waters are disputed between the states of Karnataka and Tamil Nadu. As in other Indian cities, the response to water scarcity is to transfer more water over large distances at high costs. In the case of Bangalore, the 3,384 crore (US$751.2 million) Kaveri Stage IV project, Phase II, includes the supply of 500,000 cubic meter of water per day over a distance of 100 km, thus increasing the city's supply by two thirds.[24][25]
Responsibility for water supply and sanitation
Water supply and sanitation is a State responsibility under the Indian Constitution. States may give the responsibility to the Panchayati Raj Institutions (PRI) in rural areas or municipalities in urban areas, called Urban Local Bodies (ULB). At present, states generally plan, design and execute water supply schemes (and often operate them) through their State Departments (of Public Health Engineering or Rural Development Engineering) or State Water Boards.
Highly centralized decision-making and approvals at the state level, which are characteristic of the Indian civil service, affect the management of water supply and sanitation services. For example, according to the World Bank in the state of Punjab the process of approving designs is centralized with even minor technical approvals reaching the office of chief engineers. A majority of decisions are made in a very centralized manner at the headquarters.[26] In 1993 the Indian constitution and relevant state legislations were amended in order to decentralize certain responsibilities, including water supply and sanitation, to municipalities. Since the assignment of responsibilities to municipalities is a state responsibility, different states have followed different approaches. According to a Planning Commission report of 2003 there is a trend to decentralize capital investment to engineering departments at the district level and operation and maintenance to district and gram panchayat levels.[27]
Policy and regulation
The responsibility for water supply and sanitation at the central and state level is shared by various Ministries. At the central level, The Ministry of Rural Development is responsible for rural water supply through its Department of Drinking Water Supply (DDWS) and the Ministry of Housing and Urban Poverty Alleviation is responsible for urban water supply. However, except for the National Capital Territory of Delhi and other Union Territories, the central Ministries only have an advisory capacity and a very limited role in funding. Sector policy thus is a prerogative of state governments.
Service provision
Urban areas. Institutional arrangements for water supply and sanitation in Indian cities vary greatly. Typically, a state-level agency is in charge of planning and investment, while the local government (Urban Local Bodies) is in charge of operation and maintenance.[2] Some of the largest cities have created municipal water and sanitation utilities that are legally and financially separated from the local government. However, these utilities remain weak in terms of financial capacity. In spite of decentralization, ULBs remain dependent on capital subsidies from state governments. Tariffs are also set by state governments, which often even subsidize operating costs.[28] Furthermore, when no separate utility exists there is no separation of accounts for different activities within a municipality. Some states and cities have non-typical institutional arrangements. For example, in Rajasthan the sector is more centralized and the state government is also in charge of operation and maintenance, while in Mumbai the sector is more decentralized and local government is also in charge of planning and inves

CE2304 Environmental engineering-I QUESTION BANK Water supply and sanitation in India

Water supply and sanitation in India continue to be inadequate, despite longstanding efforts by the various levels of government and communities at improving coverage. The level of investment in water and sanitation, albeit low by international standards, has increased during the 2000s. Access has also increased significantly. For example, in 1980 rural sanitation coverage was estimated at 1% and reached 21% in 2008.[1][6] Also, the share of Indians with access to improved sources of water has increased significantly from 72% in 1990 to 88% in 2008.[1] At the same time, local government institutions in charge of operating and maintaining the infrastructure are seen as weak and lack the financial resources to carry out their functions. In addition, no major city in India is known to have a continuous water supply[7] and an estimated 72% of Indians still lack access to improved sanitation facilities.
A number of innovative approaches to improve water supply and sanitation have been tested in India, in particular in the early 2000s. These include demand-driven approaches in rural water supply since 1999, community-led total sanitation, a public-private partnerships to improve the continuity of urban water supply in Karnataka, and the use of micro-credit to women in order to improve access to water
In 2008, 88% of the population in India had access to an improved water source, but only 31% had access to improved sanitation. In rural areas, where 72% of India’s population lives, the respective shares are 84% for water and only 21% for sanitation. In urban areas, 96% had access to an improved water source and 54% to improved sanitation. Access has improved substantially since 1990 when it was estimated to stand at 72% for water and 18% for sanitation.[1]
According to Indian norms, access to improved water supply exists if at least 40 liters/capita/day of safe drinking water are provided within a distance of 1.6 km or 100 meter of elevation difference, to be relaxed as per field conditions. There should be at least one pump per 250 persons.

CE2304 Environmental engineering-I QUESTION BANK Air quality management

Air quality management
Engineers apply scientific and engineering principles to the design of manufacturing and combustion processes to reduce air pollutant emissions to acceptable levels. Scrubbers, electrostatic precipitators, catalytic converters, and various other processes are utilized to remove particulate matter, nitrogen oxides, sulfur oxides, volatile organic compounds (VOC), reactive organic gases (ROG) and other air pollutants from flue gases and other sources prior to allowing their emission to the atmosphere.
Scientists have developed air pollution dispersion models to evaluate the concentration of a pollutant at a receptor or the impact on overall air quality from vehicle exhausts and industrial flue gas stack emissions. To some extent, this field overlaps the desire to decrease carbon dioxide and other greenhouse gas emissions from combustion processes.

CE2304 Environmental engineering-I QUESTION BANK UNIT 1 Water supply and treatment

Water supply and treatment
Engineers and scientists work to secure water supplies for potable and agricultural use. They evaluate the water balance within a watershed and determine the available water supply, the water needed for various needs in that watershed, the seasonal cycles of water movement through the watershed and they develop systems to store, treat, and convey water for various uses. Water is treated to achieve water quality objectives for the end uses. In the case of potable water supply, water is treated to minimize the risk of infectious disease transmission, the risk of non-infectious illness, and to create a palatable water flavor. Water distribution systems are designed and built to provide adequate water pressure and flow rates to meet various end-user needs such as domestic use, fire suppression, and irrigation.
Wastewater conveyance and treatment

Water pollution
Most urban and many rural areas no longer discharge human waste directly to the land through outhouse, septic, and/or honey bucket systems, but rather deposit such waste into water and convey it from households via sewer systems. Engineers and scientists develop collection and treatment systems to carry this waste material away from where people live and produce the waste and discharge it into the environment. In developed countries, substantial resources are applied to the treatment and detoxification of this waste before it is discharged into a river, lake, or ocean system. Developing nations are striving to obtain the resources to develop such systems so that they can improve water quality in their surface waters and reduce the risk of water-borne infectious disease

CE2304 Environmental engineering-I QUESTION BANK Scope of Environmental Engineering

Scope of Environmental Engineering
Briefly speaking, the main task of environmental engineers is to protect public health by protecting (from further degradation), preserving (the present condition of), and enhancing the environment. Environmental engineering is the application of science and engineering principles to the environment. Some consider environmental engineering to include the development of sustainable processes. There are several divisions of the field of environmental engineering.
Environmental impact assessment and mitigation
In this division, engineers and scientists use a systemic identification and evaluation process to assess the potential impacts of a proposed project , plans, programs, policies, or legislative actions upon the physical-chemical, biological, cultural, and socioeconomic components on environmental conditions.[10] They apply scientific and engineering principles to evaluate if there are likely to be any adverse impacts to water quality, air quality, habitat quality, flora and fauna, agricultural capacity, traffic impacts, social impacts, ecological impacts, noise impacts, visual (landscape) impacts, etc. If impacts are expected, they then develop mitigation measures to limit or prevent such impacts. An example of a mitigation measure would be the creation of wetlands in a nearby location to mitigate the filling in of wetlands necessary for a road development if it is not possible to reroute the road.
The practice of environmental assessment was intitiated on January 1, 1970, the effective date of the National Environmental Policy Act (NEPA) in the United States. Since that time, more than 100 developing and developed nations either have planned specific analogous laws or have adopted procedure used elsewhere. NEPA is applicable to all federal agencies in the United States

CE2304 Environmental engineering-I QUESTION BANK Development of environmental engineering

Unit 1

Development of environmental engineering

Ever since people first recognized that their health and well-being were related to the quality of their environment, they have applied thoughtful principles to attempt to improve the quality of their environment. The ancient Harappan civilization utilized early sewers in some cities. The Romans constructed aqueducts to prevent drought and to create a clean, healthful water supply for the metropolis of Rome. In the 15th century, Bavaria created laws restricting the development and degradation of alpine country that constituted the region's water supply.
The field emerged as a separate environmental discipline during the middle third of the 20th century in response to widespread public concern about water and pollution and increasingly extensive environmental quality degradation. However, its roots extend back to early efforts in public health engineering.[7] Modern environmental engineering began in London in the mid-19th century when Joseph Bazalgette designed the first major sewerage system that reduced the incidence of waterborne diseases such as cholera. The introduction of drinking water treatment and sewage treatment in industrialized countries reduced waterborne diseases from leading causes of death to rarities.[8]
In many cases, as societies grew, actions that were intended to achieve benefits for those societies had longer-term impacts which reduced other environmental qualities. One example is the widespread application of DDT to control agricultural pests in the years following World War II. While the agricultural benefits were outstanding and crop yields increased dramatically, thus reducing world hunger substantially, and malaria was controlled better than it ever had been, numerous species were brought to the verge of extinction due to the impact of the DDT on their reproductive cycles. The story of DDT as vividly told in Rachel Carson's "Silent Spring" is considered to be the birth of the modern environmental movement and the development of the modern field of "environmental engineering."[9]
Conservation movements and laws restricting public actions that would harm the environment have been developed by various societies for millennia. Notable examples are the laws decreeing the construction of sewers in London and Paris in the 19th century and the creation of the U.S. national park system in the early 20th century.
