His time of infection correlates with the time of contact with the neighbour's sewage, and the time when the neighbour was infectious. Infected fish were found in both exposure and control treatment groups in the sewage treatment plants under study (table 1). Although it is considered as an occupational hazard of agricultural workers, sewage workers, veterinarians, etc. [5-7]. Concerns about the impacts of coastal sewage discharges have led to the mapping of sewage plumes around outfalls from a number of research stations. The son had directly been in contact with the sewage when helping his father with the repair work. The surface water received agricultural and domestic sewage discharges upstream. Sewage was collected in a two-chamber septic tank located 50 m from the well. Courts had also forced building owners to provide adequate water and sewage facilities for health reasons. They would also have the wherewithal to purchase bottled water, to dig private wells, and to install private sewage systems. Using sewage for irrigation also damages the quality of crops. Heterotrophic systems may be of different size and complexity such as an island, most cities, an oyster reef or a sewage treatment plant. The number of samples collected depended on the size of the area and the population's access to sewage services. The risk for cross contamination is also increased, since water and sewage pipelines are often placed in close proximity to each other for practical reasons. There was a significant association between seropositivity and the presence of an open sewage channel running past the front of the house. Medical men's collective urban health reform efforts included improving water supplies and sewage and refuse removal, as well as people's general health. Crowded housing, the sewage system, and such dubious practices as spitting and throwing rubbish out of high-rise apartment buildings came under the spotlight. The discharge from the drainage channels enabled the farm to receive sewage at a steady rate. Urban growth had created vast problems of sewage, waste removal, housing and water supply, and had increased the quantity of breeding places for mosquitoes. We had no water, no electricity, no sewage, no prospects for the future. The payment vehicle for the programs was an increase in monthly fees for water and sewage service. The income growth and rapid urbanization have outpaced the development of infrastructures, such as paved roads, public transportation equipment, and sewage treatment systems. The impact on ammoniacal nitrogen probably again reflects sewage discharge, which rises with population. In case of sewage contamination, a multitude of agents can be expected to be found in the faeces of exposed people. In three of these outbreaks there was apparent sewage contamination ; in four outbreaks the water system was a well. Intermittent seepage of sewage into the rainwater system through a breach in the separating wall might also have contributed to the contamination. Likewise, the main stream of the sewage containing the suspended poliovirus is likely to bypass any dead ends along the migration route. Sewage and pollutants are commonly pushed out by man into relatively shallow layers of fluid. The well-to-do would be better off with the general availability of clean air, clean water, and sewage treatment. Sewage is a raw material whose irregular volume means that it can neither be controlled nor saved. Engineers normally take account of idiosyncrasies by building a system capable of withstanding as much sewage and storm water as the city can possibly produce. Their survival time in water is limited unless it is grossly contaminated with sewage. A deterioration in water quality observed in very many lakes has been due to the increase in nutrients derived from agriculture and urban sewage discharges. The effects of water supply remained practically unchanged when the type of sewage disposal was controlled for, and vice versa. Sewage water is used to irrigate soil from which vegetables are distributed to a population residing within a 150-km radius of the plantation. Portions of the underground sewage system and rainwater channels ran parallel but counter-current to each other. The optimal approach to prevention of disease is the construction of water disinfection and delivery systems and sewage disposal and treatment facilities. Parasites of flatfish in relation to sewage sludge dumping. They live in the underground sewage systems and subways in the winter and survive by begging. Removal of household offal was improved in 1899, with some incineration and a sewage farm ; inspection of milk and ice was gradually tightened. Major cities and industries require sewage treatment before discharge into rivers or large water bodies. Faecal coliforms were present in intertidal pools adjacent to sewage effluent discharge but not in any other water bodies tested. Changes in the structure and metabolic activities of periphytic communities in a stream receiving treated sewage from a waste stabilization pond. The cleaning mechanism, which consists of eight muzzles, a brush, a scraper, a water pump and a sewage-withdrawing mechanism, is installed below the robot. Although the next ten years saw great improvement and citizen input, the centralized, engineering solutions to sewage treatment won out. Huge amounts of organic materials are in the form of farm waste, city waste, sewage sludge, poultry litter and agro-industrial wastes1,2. The shaded circles represent areas where there was flooding due to a backup of sewage. Reportage concentrated on the noxious impact of sewage and ignored or exonerated the misdemeanors of industrialists. Relates to water and sewage services; includes references to drains, pipes, and water districts. Here, the diluted sewage would be sold to agriculture and transported to the ®elds in iron pipes. Sewage disposal and ventilation were therefore considered necessary measures to remove the causes of miasma and to eradicate disease. Sewage farms cannot absorb unlimited amounts of sewage nor can they survive when the quantities are low. The chemistry of sewage differed in accordance with different diets (and with the nutritional content available to different classes in society). Similarly, virtually every major industrialized city, town, and village on earth has its own sewage treatment plant. The report mentioned roads, railway infrastructure, local government sewage infrastructure, housing for elderly people, primary schools, and defence. Following a poliovaccine campaign, it is difficult to isolate poliovirus from sewage after 6 months. Sewage and industrial outfall effluent, accidental oil spills, and routine discharges from vessels are regulated separately. However, due to time and financial constraints it was not possible to include sewage treatment and disposal data in this investigation. Sewage water from the city is used to irrigate this plantation. Consequently, the discharge of domestic raw/partially treated sewage onto the polluted sites should be taken into consideration. In the current experiments, a remarkably large proportion of input poliovirus was recovered from the sewage samples collected during the four successive days. Rather, by containing and removing the sewage of the community as a whole, the system protects households which would otherwise be exposed to it. The authors thank the sewage workers and staff of the industrial plants participating in the study. There was a strong suspicion of contamination of the water distribution system from the sewage network, in all four outbreaks. The water and sewage systems were in relatively good condition. The future risk of typhoid could also be reduced by treating sewage and disinfecting water supplies. The latter, however, were at a marginally greater risk than those without any sewage disposal. There was no clear advantage, on the other hand, of having treated water or adequate sewage disposal. The terrain helped here, for sewage and water systems could often be made to work largely by gravity. The use of genetic engineering (included in excluded methods), ionizing radiation and sewage sludge is prohibited. Many countries have remained content to comply with the minimum requirements for sewage disposal. The establishment of research stations made it necessary to provide for sewage disposal. Contamination has mainly occurred through leaks of sewage into wells [5], while infections caused by swimming water have rarely been described [6 -9]. The outlet pipes lead into the municipal sewage system via a well, but some water is absorbed into the surrounding soil. The sewage was on a septic tank and soak-away system. In most cases there was a strong suggestion that contamination of the water system occurred through sewage or surface water run-off. Unprocessed sewage material was coming out at a distance of 600 m from the valley fountain. We hypothesized that consumption of raw vegetables contaminated with sewage would be associated with an increased risk of typhoid fever. Later, the sewage farm's apparent ability to convert waste into valuable produce also caught on in some western states in the late nineteenth century. Separating out sewage with heavy metals would allow the rest to be pro®tably converted to compost. Various projects undertaken by governments in major sectors, including power and energy, industry, transportation, sanitation, and sewage, can have significant environmental impacts. The sewage irrigated farmland yielded 80, 000 tonnes less grain than in clean water areas. The other category of health benefits considered in this paper are for sewage workers. However, only when sewage sludges are examined do we find really alarming concentrations of lead. Retrospective studies have been done on workers exposed to sewage sludges who have reported illnesses. The government did not announce a major project to upgrade and expand the country's sewage system until 1992. Furthermore, there is little or no smell associated with centralized sewage systems. Every year, about 2.8 billion tons of sewage is discharged, accounting for 33 per cent of the country's total. Even with this small spatial coverage, revenue raised represented more than 11 per cent of total industrial sewage revenue in 1993. Not surprisingly, these sites usually lack a water supply and provision for sewage disposal. The water in which they were found was usually extremely foul and often contained sewage. The well was probably contaminated by sewage from the camp. The sewage exposure index was defined as low or high. The water supply system and the sewage network were inspected in all cases. Thus, a possible contamination of the network system from sewage or ground surface material was suspected. The presence of sewage flowing in the street can be linked to both direct and indirect contact resulting in faeco-orally transmitted parasitic diseases. The sewage network was in a satisfactory condition. The problem is extremely complex and its mitigation will require extensive preventative measures such as sewage processing plants and natural pesticide use, among others. The mean volume of daily sewage flow at this sewage plant was about 200 000 000 litres during the study period. These examples are from corpora and from sources on the web.
