(Sump filters).  The effectiveness of the settling tanks and filters checked to improve the transparency of the water when using coagulation water sanitary doctor should independently determine the optimal dose of coagulant and verify the effectiveness of coagulation to reduce the color of water.

12.  Disinfection of water. The type of installation used a dose of chlorine contact time of water with chlorine. Sanitary doctor must determine hlorpoglaschaemost water normal dose of chlorine chlorination check compliance regime introduced into the water chlorine water flow to determine the residual chlorine and bacteriological analysis of water to produce.  Scheme of water supply facilities on it. Type the number of standpipes and placement in terms of the presence of the village aprons diversion grooves for water drainage maximum radius service columns. Number of households connected to the water supply.  Zone of sanitary protection of water sources and water supply as its organization and operation.  Sanitary and laboratory monitoring of water supply works on materials CSES and departmental labs (what tests and how often).  Water samples and analyze water. Analytical data presented in the following table.

14.  Discharge of untreated wastewater into water sources leads to microbiological contamination. According to the World Health Organization (WHO), 80% of diseases in the world are caused by improper quality and unsanitary water. In rural areas, water quality problem is particularly acute - about 90% of the rural population in the world is constantly used for drinking and bathing with contaminated water.

16.  In-depth examination (when choosing where water intake, defined lenii SBV, compiling sanitary passport, control over the accuracy of the device, and operation of facilities for local and centralized water supply is used the following methods:  - Sanitary and topographic;  - Plumbing with water sampling;  - Sanitary-epidemiological.

17.  Example of sanitary-topographic survey  Sanitary and topographical survey of the surface water source of the river Boz-Su did not reveal any sources of concentrated pollution t. E. Abandoned landfills, quarries, suction wells, etc. not found in one zone of the SOA. There is an opportunity for all three devices belts SBV.  All of the above, as well as the appearance of water so. e. the absence of odors, oily spots, floaters, Foam, a small color, etc. lead to a preliminary conclusion about the possibility of using the river as a water source for drinking purposes, and use 30 percent of the flow of the river, with 95 percent of security allow runoff water to supply water users currently on a 25-year term.

18.  Example of sanitary inspection  As a result, the sanitary survey Waterworks deviations from the requirements of KMC "Suv ​​ taminoti" existing regulations and guidelines for the design and operation of water treatment plants have been found.  On the basis of the sanitary survey we can conclude that there is no adverse impact waterworks facilities and water treatment technology on the quality of treated water.  Example of sanitary-epidemiological surveys.  As a result, the sanitary-epidemiological survey of the population using water investigated outbreaks of intestinal infections not obnaruzheno.Epizooty not.  It can be concluded that the water is safe to test the water source against epidemic.
