THE PURPOSE OF THE ACTIVITY

- Learn the basic legal documents regulating the
activity of the doctor in the communal hygiene in
the implementation of the choice of water sources
and the organization of the SOA.
- To teach students to use the legislative
framework in its selection of water sources and
the organization of the SOA.
- To teach students to competently carry out
sanitary-hygienic assessment of the organization
SOA.
THE STUDENT SHOULD KNOW
Features valuation
of open water
sources;
Hygienic
requirements for the
SOA when choosing
water source for
water supply;
Methods of sanitary
inspection
THE STUDENT SHOULD BE ABLE TO:
SBV organization
around a water
source;
Evaluation of the
Legislative Council;
Give an opinion on
the suitability of the
water source for the
water supply.
TEACHING QUESTIONS
The event was held in the territory of the
SOA?
On what hydro geological index characterized
by the formation of water?
The dimensions of the boundaries of the SOA.
Based on the legislature's public documents
organized SOA?
CONTITUTION
What indicators to look
for when sanitation,
sanitary and sanitaryepidemiological
topographical survey of
treatment facilities
What indicators
determined by technical
sanitary surveys water
source?
What documents issued
under sanitary
inspection.
CONTENTS CLASSES
normative documents border around the water source
SOA
Provisions on the design and operation of the
Legislative Council;
GOST "drinking water";
Snip "Water Supply";
1- border SBV for open water sources:
Against over 200 m;
The flow and counter position of the parties 100 m
 SOA
is organized in all water pipes,
regardless of their affiliation, supplying
water both from surface and from
underground sources, including
artificial recharge is used for domestic
and drinking needs.
SOA is organized as a
part of 3 zones:
2) and 3-zone
restrictions include
areas designated for
protection from pollution
of water sources.
1) -poyas strict regime
includes the territory
intakes locations, the
location of all areas of
water supply facilities and
water conveyance channel;
SBV organization should precede the
development and project, which includes
a) the delimitation of the area and its constituent
zones
b) development of action plans to improve the
health of SOA by eliminating existing and
prevent possible contamination of water supplies
and worsening quality of water.
Designing the SOA implementation should
begin with:
sanitary,
microbiological
sanitary-chemical,
hydrogeological investigations in
accordance with the program set out in the
proposal GOST 951-2000g. "Rules for the
selection and evaluation of the quality
sources of centralized drinking water
supply."
1st zone SOA groundwater and
surface water sources and water
supply facilities installed in order to
eliminate the possible accidental or
intentional contamination of water at
the source, at the location of water
intake and water supply facilities.
2nd and 3rd belt SBV are aimed at
preventing adverse effects on the
quality and quantity of water used or
intended for use underground and
surface sources centralized drinking
water supply through the
implementation of a set of measures,
based on local sanitation, hydro or
hydrological features of sources water
and nature of possible contamination.
QUESTIONS FOR CONTROL
1. The role of water factor in the spread of infectious
diseases.
2. The chemical composition of the drinking water in the
development of infectious disease etiology.
3. The procedure for monitoring the quality of domestic
water on a water pipe from open reservoirs.
4. What are the requirements to the quality of the water
source used for domestic drinking water supply.
5. What are the zones is SOA
CONTITATION
6. The role of the individual
elements of the aqueduct in the
spread of infection of water
(source of water supply, watersupply and sewage treatment
plants, water supply).
7. Determination of flow rate of
source water.
8. The main methods for
improving water quality.
9. Special methods for improving
water quality.
10. Laboratory quality control of
drinking water with artesian
water supply systems.
