Regulation of the order of the projecting and exploitation of the sanitary security zones of water sources and pipelines used for domestic consumption.
1. General requirments.
1.1. This Regulation of the order of the projecting and exploitation of the zones of sanitarian security (SSZ) of the sources of water supply and pipelines for household purposes compiled on the basis of ruling of the Central Elective Committee (CEC) and Council of the People's Commissars (CPC) of the USSR on 17th may 1973. “On sanitarian security of the pipelines and sources of the water supply”, “On the basics of the legislation of the USSR and allied republics about the healthcare” (1969), “Foundations of the water legislation of the USSR and allied republics (1970).
1.2. This regulation determines the order of the projecting and exploitation of (SSZ) of the sources of centralized water supply and water pipelines, which provide water for household needs for citizens, industrial organization’s personnel as well as for organizations that are in need of drinking quality water and predetermined for an organizations that are projecting and exploit water intake stations and water pipelines, as well as for the sanitary epidemic services, that are performing sanitary supervision on a governmental level.
1.3 ZSS are organized at all water supplying pipelines, regardless from their status and meaning, providing water as from surface as well as from underground sources, including artificial supplement, used for domestic consumption. SSZ’s main purpose is protection of the sources of water supply as well as of water facilities and surrounding territories from pollution.
1.4. ZSS is organized within three belts: The first belt (belt of a strict regime) includes a territory of location of all the water intake structures, all water supplying facilities and of a water pipeline; the second and the third belts (belts of the restrictions) include a territory, predetermined for a security of the sources of water supply from pollution.
Sanitarian security of the water pipelines is assured by sanitarian security buffer stripe. In each of the three belts, as well as within sanitarian security buffer stripe, respectively to their meaning, special regime is established and course of events is being selected that exclude the possibility of water quality deterioration.
1.5. Organization of SSZ should be preceded by it’s project elaboration, which includes:
a. determination of the boundaries of the zone of sanitarian security and its belts;
b. development of a plan of activities for the improvement of SZZ by removing existing and prevention of a possible water source pollution and of the water supply sources and deterioration of a water quality.
1.6. SSZ boundaries definition and elaboration of a complex of the necessary sanitary events, depend on the type of water supply source (underground or on surface), projected or used for household consumption, depending on the level of its natural protection and possibility of microbial or chemical pollution, depending on sanitary features, hydro-geological and hydrological conditions, as well as from the type of pollutants.
1.7. The main sources of microbial pollution of the surface and underground sources of water supply are household waste waters, production drain waters of individual sectors of industry (including poultry-keeping farms and livestock), surface drain waters (rain, melted, swabbing), as well as field sanitation, filtering and irrigation. The range of the microorganisms spread depends on the speed of a current of underground or surface water source and of the extent of its primary pollution and is limited by the time of survival and preservation of virulence of microorganisms in a water environment. Consideration of the other factors restricting microorganisms spread (adsorption, water temperature etc.) allowed if the impact of these factors is sharply expressed and their patterns sufficiently explored.
1.8. The main sources of chemical pollution of surface and underground water supply sources are industrial enterprise waste waters, drives and other compilations of production wastes, as well as surface water drains from the territories of industrial enterprises, warehouses of chemical pesticides and fertilizes of the agricultural fields. The possibility of the impact of highly mineralized waters from above and beyond located water horizons, sea waters at sea coasts.
Ability to transformation of chemical pollution, as well as to reduce their concentration (sorption, fallout into sludge etc.) under the influence of the physical-chemical processes in the surface and underground water supply sources, may be considered if the processes are influencing the range of chemical pollution, sharply expressed and their patterns sufficiently explored.
1.9. Projection of the SSZ must begin with execution of sanitary, microbiological, sanitary-chemical, hydro-geological and hydrological research in accordance with the program contained in the annex 1 to state standard (ÃÎÑÒ 17.1.3.03-77) “Nature preservation. Hydrosphere. Rules of selection and quality evaluation of the sources of centralizes household water consumption water supply”. This, according to local conditions, additional research may be provided, necessary for determination of the SSZ boundaries, as well ass for development of the part of the project, which is related to execution of sanitary events within boundaries of the projecting SSZ. Execution of necessary works for projecting SSZ must be carried out by the projecting organization, funded by the customer.
1.10. The possibility of SSZ organization should be decided at the stage of selection of centralized household consumption water source. State standard (ÃÎÑÒ 17.1.3.03-77). SSZ project must be an integral part of the household consumption water supply project and should be developed concurrently with the last, in case reconstruction of the water facilities – concurrently with their project. For existing water supply pipelines, that do not have preinstalled zones of sanitarian security, SSZ project is being developed especially.
1.11. SSZ project, as well as a plan of measures, intended to secure the required water quality of the source of the water supply, must be accorded with the organs and institutions of sanitary epidemic services, organs of regulation of water usage and water protection, organs of communal housekeeping and organs of the Ministry of Geology (for using of underground waters), as well
as with other interested Ministries and institutions and should be approved in a specified order (see section 7.1.3 of a current Regultion).
1.12. In especially difficult circumstances for settings of the appropriate size of the second and third belts and in order of exemption having necessary justifications and in agreement with organizations mentioned in section 1.11. sizes of the second and the third belts can be reduced (or combined for several sources of water supply), provided, that by the special events the constancy of the drinking water quality will be secured, provided by state standard (ÃÎÑÒ 2874-82) “Drinking water Hygienic requirements and quality control”.
1.13. The established boundaries of SSZ and its belts may be reviewed in case of existing or forthcoming changes of conditions of exploitation of the water supply sources (including productivity of water intake stations and underground waters) or local sanitary conditions in agreement with the organizations, mentioned in section 1.11. of current Regulation. Projecting and adoption of the new boundaries should be executed in the same order as in the original.
2. Appointment of the belts of sanitarian security zone.
2.1 The first SSZ belt of underground and surface sources of water supply and water supplying facilities installed in order to eliminate accidental or deliberate pollution of the water source in place of discovery of water intake stations and water supplying facilities.
2.2. The second and the third SSZ belts are aimed at preventing the adverse influence on quality and quantity of water used or alleged underground and surface sources of centralized household water consumption through the implementation of a set of measures, based on local sanitary conditions, hydro-geological or hydrological features of the sources of water supply and a character of their possible pollution.
2.3. The second and the third SSZ belts of underground and surfaces sources of water supply are designed to prevent pollution of the water sources. In case when pollution of water sources already has place, it should not exceed the limits regulated by ÃÎÑÒ 17.1.3.03-77. “Nature preservation. Hydrosphere. Rules of selection and quality evaluation of the sources of centralizes household water consumption water supply” and enabling water processing by means of modern technology to ensure its quality, to the requirements of state standard (ÃÎÑÒ 2874-82) “Drinking water. Hygienic requirements and quality control”.
2.4. The boundaries of the second and the third SSZ belts of underground and surface sources of water supply are determined by calculations, based on research of:
- sanitary and hydrological or hydro-geological features of water supply sources;
- microbial and chemical pollution differences on their level of stability in water of underground and surface sources of water supply.
2.5. During rationalization of the second and the third SSZ belts of underground sources of water supply it is necessary to take into consideration, that inflow of underground waters from the water horizon to water intake station happens only from the zone of water intake station nutrition, shape and size of which on the plan depend on:
- the type of the water intake station (individual chinks, group of chinks, linear number of chinks, horizontal drains etc.);
- by the size of water intake (water consumption values) and descent of the level of underground waters;
- hydro-geological features, that determine shape and size of water carrying layer, conditions of its nutrition and drainage.
3. Water intake from underground sources
3.1. The definition of the boundaries of the first SZZ belt
3.1.1. Water intakes of underground waters should be placed, in general, outside of the territories of industrial enterprises and housing estates.
The first SSZ belt is installed on the distance not less than 30 m. from water intake – when using protected underground waters and on a distance not less than 50 m. – when using not enough protected underground waters.
When using group of underground water intakes the boundary of the first belt should be located on a distance not less that 30 m. and 50 m. respectively, from extreme chinks (or mine wells).
Notes:
1. For water intakes, located on the territory of the object, excluding possibility of soil pollution and underground waters, as well as water intake stations, located in a favorable sanitary-technical and hydro-geological conditions, the size of the first SSZ belt can be reduced by an agreement of local organs of sanitary epidemic services till 15 m. and 25 m. respectively.
2. Protected underground waters include pressured and non pressured interlayer waters, having within all SSZ belts solid water-resistant roofing, excluding possibility of nutrition from the overlying not well enough protected water-bearing horizons.
3. Not well enough protected underground waters include:
a. ground waters, meaning, underground waters of the first from soil surface non pressured water-bearing horizon, receiving nutrition at area of its distribution;
b. pressured and non pressured interlayer waters, which in natural condition or as a result of exploitation of water intake receive nutrition at area of SSZ from overlaying not well enough protected water-bearing horizons through hydro-geological windows or porous soil roofing, as well as from the watercourses and water basins through a direct hydraulic bound.
3.1.2. In case of artificial replenishment of ground waters the boundary of the first SSZ belt for water intakes should be installed as for underground not well enough protected source of water supply on a distance not less than 50 m. from water intake and not less than 100 m. from infiltration facilities (reservoirs, canals etc.)
3.1.3. Into the first belt’s boundaries of infiltration of water intakes of underground waters, coastal territory between water intake and surface water basin must be included, if the distance between them is less than 150 m.
3.1.4.For river bed water intakes SSZ should be included as for surface sources of water supply.
3.2. The definition of the boundaries of the second SSZ belt.
3.2.1. The second SSZ boundary is determined by hydrodynamic calculations, based on conditions that if from outside water-bearing horizon will receive microbial (unstable) pollutions, they will not reach the water intake.
For an effective protection of underground water source from microbial (unstable) pollution it is necessary that estimated time (T m) of pollution progression with underground waters from the boundary of the second belt till water intake is sufficient for the loss of viability and virulence of pathogenic microorganisms, i.e., for an effective self-cleaning.
3.2.2. Using ground waters for water supply, pollution of which is possible from above through the aeration zone, for determination of the boundary of the second SSZ belt it is necessary to take into account time (T m), displayed in section 1. table ¹1.
Note: Recommendation mentioned in section 3.2.2. apply to infiltration water intake of underground waters.
3.2.3. Using for a water supply pressured and non-pressured interlayer waters in condition of possibility of receiving pollution through hydro-geological windows or porous rock roofing of a water-bearing horizon or when there is hydraulic connection with a surface water basin for determination of the boundaries of the SSZ second belt time (T m) specified in section 2 table ¹1 should be taken into consideration.
Dependence of the estimated time T m from natural conditions:
| Hydrological Conditions | Ò m (days) |
| within I and II climatic regions+ | within III and IV climatic regions+ |
| 1.Ground waters |
| a) in case there is hydraulic ñconnectio with the open water basin | 400 | 400 |
| b) in case there is no hydraulic connection with the open water basin | 400 | 200 |
| 2. Pressured and non-pressured interlayer waters: |
| à) in case of direct hydraulic connection with the open water basin | 200 | 200 |
| b) in case there is no direct hydraulic connection with the open water basin | 200 | 100 |
* Climatic region in accordance with sanitary regulation (Ñíèï. Reg. 7-71) “Residential buildings. Norms of projecting”.
3.3. The definition of the boundaries of the third SSZ belt.
3.3.1 The third SSZ belt boundary is determined by hydrodynamic calculations, based on conditions, that if outside of its boundaries water-bearing horizon receives chemical (stable) pollutants, either they will not reach water intake point, moving together with underground waters outside of nutrition zone, or will reach water intake, but not earlier of estimated time T x.
3.3.2. For protection (of underground water source from chemical pollution, mainly stable, it is necessary that the time of a polluted water movement from the boundaries of the third SSZ belt till water intake is more of adopted (medial)) technical exploitation duration of a water intake. In this cases for the protection from chemical pollutions the time T x should be not less than 25 years.
Note. In accordance with paragraph 1.8 of current Regulation cases of sharply expressed and repeated unstable chemical pollution are not excluded. The possibility of accounting of these conditions when determining the boundaries of the third SSZ belt, must be confirmed by the specific scientifically proven data.
3.3.3. In cases of having a direct hydraulic connection infiltration water intake of underground waters with surface water basin, part of which by calculations entering the boundaries of the second and the third SSZ belts infiltration water intake of underground waters, it is necessary to install the second and the thirds SSZ belts and for surface water basin in accordance with sections 4.2 and 4.3 of this Regulation.
3.3.4. Calculation methods for determination of the boundaries of the second and the third SSZ belts of underground sources of water supply for various hydro-geological conditions, accorded with Government Building Institution of the USSR, published by VNII VODGEO in 1983 (“Recommendations on hydrological calculations for determination of the second and the third belts of zones of sanitary protection of underground sources of household water supply”, Moscow 1983).
