Pros and cons thesis

Sanitation refers to public health conditions related to clean drinking water and treatment and disposal of human excreta and sewage. Sanitation systems aim to protect human health by providing a clean environment that will stop the transmission of diseaseespecially through the fecal—oral route.

A range of sanitation technologies and approaches exists. Some examples are community-led total sanitationphd thesis report on sanitation, container-based sanitationecological sanitationemergency sanitationenvironmental sanitation, onsite sanitation and sustainable sanitation.

A sanitation system includes the capture, storage, transport, treatment and disposal or reuse of human excreta and wastewater. This is referred to as the "sanitation value chain" or "sanitation economy".

Several sanitation "levels" are being used to compare sanitation service levels within countries or across countries. The Human Right to Water and Sanitation was recognized by the United Nations UN General Assembly in Sanitation is a global development priority and the subject of Sustainable Development Goal 6, phd thesis report on sanitation.

There are some variations on the use of the term "sanitation" between countries and organizations. The World Health Organization defines the term "sanitation" as follows:.

The word 'sanitation' also refers to the maintenance of hygienic conditions, through services such as garbage collection and wastewater disposal. Sanitation includes all four of these technical and non-technical systems: Excreta management systems, wastewater management systems included here are wastewater treatment plantssolid waste management systems as well as drainage systems for rainwater, also called stormwater drainage. Another example of what is included in sanitation is found in the handbook by Sphere on "Humanitarian Charter and Minimum Standards in Humanitarian Response" which describes minimum standards in four "key response sectors" in humanitarian response situations.

One of them is "Water Supply, Sanitation and Hygiene Promotion" WASH and it includes the following areas: Hygiene promotion, water supplyexcreta management, vector controlsolid waste management and WASH in disease outbreaks and healthcare settings. Hygiene promotion is seen by many as an integral part of sanitation. The Water Supply and Sanitation Collaborative Council defines sanitation as "The collection, transport, treatment and disposal or reuse of human excretadomestic wastewater and solid waste, and associated hygiene promotion.

Despite the fact that sanitation includes wastewater treatment, the two terms are often used side by side as "sanitation and wastewater management". Another definition is in the DFID guidance manual on water supply and sanitation programmes from [14]. It encompasses too the re-use and ultimate disposal of human excreta. The term environmental sanitation is used to cover the wider concept of controlling all the factors in the physical environment which may have deleterious impacts on human health and well-being.

In developing countries, it normally includes drainage, solid waste management, and vector control, in addition to the activities covered by the definition of sanitation.

Sanitation can include personal sanitation and public hygiene. Personal sanitation work can include handling menstrual wastephd thesis report on sanitation, cleaning household toiletsand managing household garbage.

Public sanitation work can involve garbage collection, transfer and phd thesis report on sanitation municipal solid waste managementcleaning drains, streets, schools, trains, phd thesis report on sanitation, public spacescommunity toilets and public toiletssewersoperating sewage treatment plantsetc.

The overall purposes of sanitation are to provide a healthy living environment for everyone, to protect the natural resources such as surface watergroundwatersoiland to provide safety, security phd thesis report on sanitation dignity for people when they defecate or urinate.

It is derived from the human right to an adequate standard of living. Effective sanitation systems provide barriers between excreta and humans in such a way as to break the disease transmission cycle for example in the case of fecal-borne diseases. One of the main challenges is to provide sustainable sanitationespecially in developing countries. Maintaining and sustaining sanitation has challenges that are technological, institutional and social in nature. Sanitation infrastructure has to be adapted to several specific contexts including consumers' expectations and local resources available.

Sanitation technologies may involve centralized civil engineering structures like sewer systemssewage treatmentsurface runoff treatment and solid waste landfills. These structures are designed to treat wastewater and municipal solid waste. Sanitation technologies may also take the form of relatively simple onsite sanitation systems.

This can in some cases consist of a simple pit latrine or other type of non-flush toilet for the excreta management part. Providing sanitation to people requires attention to the entire system, not just focusing on technical aspects such as the toiletfecal sludge management or the wastewater treatment plant. All need to be thoroughly considered. The benefits to society of managing human excreta are considerable, for public health as well as for the environment.

For developing countries, the economic costs of inadequate sanitation is a huge concern. For example, phd thesis report on sanitation, according to a World Bank study, economic losses due to inadequate sanitation to The Indian economy are equivalent to 6.

Availability of toilet phd thesis report on sanitation home on the other hand, positively contributes to economic well-being of women as it leads to an increase in literacy and participation in labor force.

The term sanitation is connected with various descriptors or adjectives to signify certain types of sanitation systems which may deal only with human excreta management or with the entire sanitation system, i. also greywater, stormwater and solid waste management — in alphabetical order:. InJMP defined a new term: "basic sanitation service". This is defined as the use of improved sanitation facilities that are not shared with other households.

A lower level of service is now called "limited sanitation service" which refers to use of improved sanitation phd thesis report on sanitation that are phd thesis report on sanitation between two or more households.

The term "dry sanitation" is not in widespread use and is not very well defined, phd thesis report on sanitation. It usually refers to a system that uses a type of dry toilet and no sewers to transport excreta. Often when people speak of "dry sanitation" they mean a sanitation system that uses urine-diverting dry toilet UDDTs. Environmental sanitation encompasses the control of environmental factors that are connected phd thesis report on sanitation disease transmission.

Subsets of this category are solid waste management, water and wastewater treatment, industrial waste treatment and noise pollution control. Lack of sanitation refers to the absence phd thesis report on sanitation sanitation. In practical terms it usually means lack of toilets or lack of hygienic toilets that anybody would want to use voluntarily.

The result of lack of sanitation is usually open defecation and open urination but this is of less concern with associated serious public health issues. Onsite sanitation or on-site sanitation is defined as "a sanitation system in which excreta and wastewater are collected and stored or treated on the plot where they are generated". Examples are pit latrines no treatment and septic phd thesis report on sanitation primary treatment of wastewater. On-site sanitation systems are often connected to fecal sludge management FSM systems where the fecal sludge that is generated onsite is treated at an offsite location.

Wastewater sewage is only generated when piped water supply is available within the buildings or close to them. A related term is a decentralized wastewater system which refers in particular to the wastewater part of on-site sanitation.

Similarly, an onsite sewage facility can treat the wastewater generated locally. Safely managed sanitation is the highest level of household sanitation envisioned by the Sustainable Development Goal Number 6. In other words, safely managed sanitation is a basic sanitation service where in addition excreta are safely disposed of in situ or transported and treated offsite.

Wastewater management consists of collection, wastewater treatment be it municipal or industrial wastewaterdisposal or reuse of treated wastewater. The latter is also referred to as water reclamation. Sanitation systems in urban areas of developed countries usually consist of the collection of wastewater in gravity driven sewers, its treatment in wastewater treatment plants for reuse or disposal in rivers, lakes or the sea.

In developing countries most wastewater is still discharged untreated into the environment. Alternatives to centralized sewer systems include onsite sanitationdecentralized wastewater systemsdry toilets connected to fecal sludge management.

Sewers are either combined with storm drains or separated from them as sanitary sewers. Combined sewers are usually found in the central, older parts or urban areas. Heavy rainfall and inadequate maintenance can lead to combined sewer overflows or sanitary sewer overflowsi. Industries often discharge wastewater into municipal phd thesis report on sanitation, which can complicate wastewater treatment unless industries pre-treat their discharges. Disposal of solid waste is most commonly conducted in landfillsbut incineration, recyclingphd thesis report on sanitation, composting and conversion to biofuels are also avenues.

In the case of landfills, advanced countries typically have rigid protocols for daily cover with topsoil, where underdeveloped countries customarily rely upon less stringent protocols.

Daily cover also minimizes odor emissions and reduces windblown litter. Likewise, developed countries typically have requirements for perimeter sealing of the landfill with clay-type soils to minimize migration of leachate that could contaminate groundwater and hence jeopardize some drinking water supplies. For incineration options, the release of air pollutantsincluding certain toxic components is an attendant adverse outcome. Recycling and biofuel conversion are the sustainable options that generally have superior lifecycle costs, particularly when total ecological consequences are considered.

Sanitation within the food industry means the adequate treatment of food-contact surfaces by a process that is effective in destroying vegetative cells of microorganisms of public health significance, and in substantially reducing numbers of other undesirable microorganisms, but without adversely affecting the food or its safety for the consumer U. Food and Drug AdministrationCode of Federal Regulations21CFR, USA. Sanitation Standard Operating Procedures are mandatory for food industries in United States.

Similarly, phd thesis report on sanitation, in Japan, food hygiene has to be achieved through compliance with food sanitation law. In the food and biopharmaceutical industries, the term "sanitary equipment" means equipment that is fully cleanable using clean-in-place CIP and sterilization-in-place SIP procedures: that is fully drainable from cleaning solutions and other liquids. The design should have a minimum amount of deadleg, or areas where the turbulence during cleaning is insufficient to remove product deposits.

The surface is usually electropolished to an effective surface roughness of less than 0. In many settings, provision of sanitation facilities alone does not guarantee good health of the population. Studies have suggested that the impact of hygiene practices have as great an impact on sanitation related diseases as the actual provision of sanitation facilities, phd thesis report on sanitation.

Hygiene promotion is therefore an important part of sanitation and is usually key in maintaining good health. It usually involves a participatory approach of engaging people to take responsibility of WASH services and infrastructure including its operation and maintenance.

The three key elements of promoting hygiene are; mutual sharing of information and knowledge, the mobilization of affected communities and the provision of essential material and facilities. Sanitation is a necessity for a healthy life.

Lack of sanitation can result in feces-contaminated drinking water and cause life-threatening forms of diarrhea to infants. Ininfectious diarrhea resulted in about 0.

Approximately two billion people are infected with soil-transmitted helminths worldwide. It happens in environments where there is no effective separation of humans and feces due to lack of sanitation. When analyzing environmental samples, various types of indicator organisms are used to check for fecal pollution of the sample.

Commonly used indicators for bacteriological water analysis include the bacterium Escherichia coli abbreviated as E. coli and non-specific fecal coliforms. With regards to samples of phd thesis report on sanitationsewage sludgebiosolids or fecal matter from dry toiletshelminth phd thesis report on sanitation are a commonly used indicator.

With helminth egg analysis, eggs are extracted from the sample after which a viability test is done to distinguish between viable and non viable eggs.
