Definition of terms
For the purposes of this Order, it is understood that:
a) industrial wastewater is wastewater laid down in part B of Annex 1 to this Order, as
well as wastewater that is not laid down in this part of the Annex if it is discharged from
production or other similar facilities,
b) urban wastewater is wastewater discharged from households or services, being mainly a
product of human metabolism and activities in households (sewage), or their mixture
with industrial wastewater or rainwater,
c) source of pollution is a territory of a community (or a separate part of its territory that
has a separate sewerage), a territory of a military zone, or an area of an industrial
company or another object if separate wastewater is discharged from such area/territory
into surface water. Water from rainfall separators is not considered wastewater if the
separator function meets the preconditions determined by the water authority. An
industrial company area or a part of such an area or a part of some other object from
which wastewater is discharged into a through-flow cooling system of steam turbines
from which it is discharged into surface water are also considered a separate source of
pollution.
d) emission standards are the maximum permissible values of wastewater pollution
indicators laid down in Annex 1 to this Order,
e) emission limits are the maximum permissible values of wastewater pollution indicators
that are determined by the water authority in its permit for the wastewater discharge into
surface water,
f) type of emission standards and limits is its determination in the following units:
1. concentration expressed as weight per litre,
2. minimum treatment efficiency of a wastewater treatment plant in %,
3. the quantity of pollution discharged for a certain time period,
4. relative quantity of pollution discharged, expressed as a ratio of a weight unit to a
weight unit of the substance or raw material used during production or for the
product,
2
Council Directive of 21 May 1991 on urban wastewater treatment (91/271/EEC).
g) pollution standards are the maximum permissible values of indicators of permissible
surface water pollution in units of weight, radioactivity or bacterial pollution per a
volume unit; the values are determined in Annex 3 to this Order,
h) the target status of water quality in a water course is a state that fulfils the water
protection objectives laid down in Annex 2 to this Order,
i) available technology in the area of wastewater treatment is a wastewater disposal or
treatment technology that is available,
j) combined approach is a method of determining the target emission limits based on the
requirement to meet simultaneously the emission and pollution standards as well as the
target status of water quality in a water course, having regard to the best available
technologies in production3 and to the available technologies in wastewater disposal.
While determining the target emission limits, the water authority shall also set a
deadline by which the limits shall be achieved and the conditions under which the
wastewater may be discharged till the target emission limits are achieved. These
conditions are laid down by the water authority in accordance with § 6, art.2.

(1) The emission standards “p” laid down in Table 1a, Annex 1 to this Order, the emission
standards laid down in tables 2a, 2b and 3, Annex 1 to this Order, and the emission limits
determined by water authorities according to these standards in their wastewater
discharge permits are considered complied with if the extent of exceeding them does not
go beyond the values laid down in Annex 5 to this Order.
(2) The emission standards “m” laid down in Table 1a, Annex 1 to this Order and the
emission limits “m” determined by a water authority in its wastewater discharge permit
must not be exceeded.

of negative results does not exceed the number laid down in Annex 5 to this Order.
(6) The product of the annual volume of wastewater discharged and the annual arithmetic
mean of the results of wastewater analyses is critical for assessing whether the values of
the annual quantity of pollution discharged (for a pollutant or group of pollutants
determined in the wastewater discharge permit) were complied with or not. Data from the
previous calendar year shall be taken as a basis to assess whether the values of the annual
quantity of pollution discharged were complied with or not.
(7) The ratio of calculated annual quantity of pollution discharged to the annual amount of
substance or raw material used in production or for the product is critical for assessing
whether the values of the annual average quantity of pollution discharged (determined in
the wastewater discharge permit) were complied with or not. The values for the previous
calendar year shall be used for the assessment.
(8) Monitoring under normal operational conditions shall be used to assess whether the
wastewater discharge permit was complied with or not.
(9) The emission limits are not considered complied with in case it was proved that they had
been achieved by diluting the wastewater.
§8
Measurement of the volume of discharged wastewater and its pollution
(1) If a water authority determines the permissible treatment efficiency as a type of an
emission limit then it shall also determine the place to measure the volume and quality of
wastewater flowing into the wastewater treatment plant as well as the method to monitor
and keep records of the amounts of substances that characterise the production process.
(2) Together with an urban wastewater discharge permit, a water authority shall determine
the minimum monitoring frequency and sample type according to the values laid down in
Table 1, Annex 4 to this Order. In case of permits to discharge other kinds of wastewater,
the authority shall determine the monitoring frequency and sample types that are
adequate to these values.
(3) In its permit to discharge urban wastewater from wastewater treatment plants with
capacity over 2 000 population equivalent, the water authority shall determine the
frequency and method to monitor the pollution removal efficiency in the pollution
indicators N-total and P-total.
(4) Sampling must be equally distributed over time along the whole calendar year, which
applies also in case that the number of samples taken is higher than the minimum number
determined by this Order. This does not apply to controlled or irregular discharge of
wastewater and discharge of wastewater from campaign productions for which the
monitoring method is determined by the water authority adequately to the requirements
of this Order and to the local conditions.
(5) When granting a permit to discharge wastewater containing particularly hazardous
harmful substances laid down in Table 3, Annex 1 to this Order into surface water, the
water authority shall determine the method to monitor such water on the basis of 24-hour
coalesced samples (proportional to the flow) while the daily volume of wastewater
discharged also has to be measured. The monthly averages of concentrations and relative
amounts shall be determined on the basis of daily measurements of concentrations, the
wastewater volume and values that characterise the production. When granting a permit
to discharge wastewater containing these particularly hazardous harmful substances in
amount that is smaller than the amount determined in Table 2, Annex 4 to this Order, the
water authority shall determine the monitoring method that is adequate to the local
conditions.
(6) When granting a permit to discharge wastewater containing particularly hazardous
harmful substances that are not laid down in Table 3, Annex 1 to this Order and
wastewater containing hazardous harmful substances into surface water, the water
authority shall determine a method to monitor the wastewater with minimum frequency
of twelve 24-hour coalesced samples (proportional to the flow) per year while the volume
of wastewater discharged also has to be measured, including monitoring of concentration
and amount of these substances. When determining the monitoring method, the water
authority shall take into account their harmfulness level, the amount discharged per a
certain time period, their concentrations in the wastewater discharged, the local
conditions, and the requirements of this Order. If a daily or monthly amount of
particularly hazardous harmful substances and hazardous harmful substances discharged
is smaller then the amounts laid down in Table 3, Annex 4 to this Order, the water
authority shall determine a method to monitor the wastewater that is adequate to the
requirements of this Order and to the local conditions.
(7) When granting a permit to discharge wastewater containing particularly hazardous
harmful substances into sewerage, the water authority shall determine the method to
measure the wastewater in a way that corresponds to the procedure described in art. 5
and 6.
(8) When granting a permit to discharge wastewater containing harmful substances not laid
down in Annex 1 to this Order, the water authority shall determine the method to measure
the wastewater in a way that corresponds to the procedure described in art. 5 and 6.
(9) If urban wastewater is treated before being discharged into surface water and if the water
authority determines the minimum treatment efficiency as the emission limit in
accordance with the values in Table 1b, Annex 1 to this Order, samples of wastewater
must be taken at the same time both from the inflow into the wastewater treatment plant
and from the place where treated water is discharged into the surface water.
(10) In its permit to discharge wastewater, the water authority shall stipulate that the quality
measurement of the wastewater discharged shall be carried out by an authorised
laboratory (§ 92, art. 1 of the Act).
§9
(1) When granting a permit to discharge wastewater from individual family houses or
constructions for individual recreation or from other constructions of a similar size, the
water authority shall take adequate steps in accordance with this Order.
(2) When determining the conditions for discharge of mining water into surface water8 the
water authority shall take similar steps in accordance with this Order.
§ 10
Sensitive areas
(1) All surface waters on the territory of the Czech Republic are hereby classified as sensitive
areas.
(2) Emission standards for the sensitive areas and for wastewater discharge into surface
water that influences water quality in sensitive areas, in the pollution indicators total
nitrogen, nitrogen compounds and total phosphorus correspond to the values of these
pollution indicators laid down in Table 1a and 1b, Annex 1 to this Order.
§ 11

6)
The value is valid for the period in which the wastewater temperature at the outlet from the biological
treatment is lower than 12 o C; for this purpose, the wastewater temperature is considered lower than 12 o C if out
of 5 measurements carried out during the day, the temperature in at least 3 of the measurements is below 12 o C.
7)
The permissible limits for CODCr, BOD5 , and suspended solids are determined by the water authority
adequately to this Order, on the basis of the quality and status of water in the watercourse and of the local
conditions.
8)
When determining the limits for nitrogen and phosphorus, the water authority shall take into account the time
plan of construction and reconstruction of the technological stages for nitrogen and phosphorus removal, for the
specific agglomerations of the Czech Republic, that was adopted by the Government on the basis of the
agreement between the Czech Republic and the EU on the transitional period for implementation of the Directive
91/271/EEC within the “Strategy of financing the implementation of the Council Directive on urban wastewater
treatment”. For the specific agglomerations referred to in the Strategy and for the determined construction or

The treatment efficiency related to the pollution load at the inlet to the wastewater treatment plant.
The permissible treatment efficiency does not have to be achieved for a permitted number of individual
determinations according to Annex 5 to this Order. In order to determine the minimum treatment efficiency, the
sample type A or B or C referred to in note 3) to Table 1, Annex 4 shall be used in harmony with the water
authority´s decision.
2)
Total nitrogen means a sum of all nitrogen forms, i.e. nitrogen determined by Kjeldahl method (organic and
ammoniacal nitrogen), nitrite nitrogen and nitrate nitrogen.
3)
The permissible limits for CODCr, BOD5 , and suspended solids are specified by the water authority adequately
to this Order, on the basis of the quality and status of water in watercourse and of the local conditions.
4)
The value is valid for the period in which the wastewater temperature at the outlet from the biological
treatment is lower than 12 o C; for this purpose, the wastewater temperature is considered lower than 12 o C if out
of 5 measurements carried out during the day, the temperature in at least 3 of the measurements is below 12 o C.
A water authority may use the limits determined as the permissible minimum treatment
efficiency also for urban wastewater in cases when using this kind of limits is more suitable
due to the kind of wastewater, treatment technology used and the local conditions.
Table 1b can be used particularly for big quantities of industrial wastewater which contains
organic pollution, i.e. for high concentrations of pollution indicators at the inlet to wastewater
treatment plant, or if the volume of industrial wastewater exceeds 50 % of the total volume of
wastewater discharged.

In case of incineration plants, wastewater from gas cleaning is concerned. The limit concentration values shall
be considered to be achieved if:
- for suspended solids – 95 % of the daily measured values do not exceed the limit value and none of the
values exceeds 45 mg/l,
- - for heavy metals and arsenic – in a year, maximally one of the monthly measured values exceeds the
limit concentration value,
- for dioxins and furans, measured every six months (for the first year every three months), none of the
values measured exceeds the limit concentration value.
The limit values must be achieved at site where wastewater from the installation for cleaning the combustion
gases containing the above substances is discharged from the combustion or co-combustion installation. If
wastewater from cleaning the combustion gases is treated outside the combustion or co-combustion installation
in a wastewater treatment plant intended only for treatment of this kind of wastewater, the limit values shall be
applied at the outlet from this wastewater treatment plant. If the wastewater from cleaning combustion gases is
treated together with other wastewater in or outside the place where it was produced the limit values must be
modified accordingly.
The permit must determine the operational continuous monitoring of the wastewater, at least of its pH,
temperature and discharge.

The pollution standards set out in column “permissible values” must be achieved within five years after the Czech Republic accesses the EU. The
“target” pollution standards must be achieved by December 22nd, 2012.
a)
The pollution standards set permissible pollution of surface water at the flow Q355, or at the minimum guaranteed flow of water in the watercourse or the value that is
considered to be met if not exceeded by more than 5 % of the annual samples. For the values of the following indicators: pH, BOD5 , non-ionized ammonia, ammonia ions,
nitrites, total chlorine, total zinc, and dissolved copper. If sampling frequency is lower than one sample per month all of the samples must meet the above values. Permissible
percentages of failures for dissolve oxygen are given in the table. For suspended solids, the arithmetic mean of concentration is used as the characteristic value.
1)
Presence of fish in water containing higher concentration of Cu may indicate dominating concentrations of organo-copper(II) complexes.

The pollution standards express permissible pollution of surface water at the flow Q355, or at the minimum
guaranteed flow of water in the watercourse or the value that is met if the number of samples that do not meet
this standard does not exceed 5 %. For evaluation of achievement of the values of the indicators in the “target”
columns, the value with annual non-exceedance probability of 90 % is used.
1)
The values are the upper limits for the average annual temperatures (the low and high ones).
2)
The limits shall not be applied if there are no organoleptic defects of the drinking water.
3)
The method recommended is CSN 75 7505; possible updating of the standard shall be published in the Official
Journal of the Ministry of Environment.
4)
A sum of concentrations of six substances: fluoranthene, benzo(b)fluoranthene, benzo(k)fluoranthene,
benzo(a)pyrene, benzo(g,h,i)perylene and ideno(1,2,3-c,d)pyrene.
5)
A sum of all relevant pesticides that are being determined.
6)
The method recommended is CSN 75 7506; possible updating of the standard shall be published in the Official
Journal of the Ministry of Environment.
“(0)” = extreme climate or geographic conditions
The “target” pollution limits for surface water used in accordance with the relevant category
of raw water treatment for production of drinking water must be achieved by December 22nd,
2012.
Categories of the standard methods to produce drinking water from raw water

a)
The pollution standards set permissible pollution of surface water at the flow Q355, or at the minimum
guaranteed flow of water in the watercourse or the value that is considered to be met if not exceeded by more
than 5 % of the annual samples. For the values of indicators in columns “permissible”, the value with annual
non-exceedance probability of 80 % is used for coliform bacteria and thermo -tolerant coliform bacteria. For
evaluation of achievement of the values of the indicators in the “target” columns, the value with annual nonexceedance probability of 90 % is used.
Notes:
1. The determination method according to Czech Standard (CSN) 830531-3. In case of water that can
be filtrated, membrane filtration of 100 ml shall be used; in case of water that cannot be filtrated,
1 ml or further dilution is tested. The results shall be recounted for 100 ml.
2. The determination method according to TNV 757835. In case of water that can be filtrated,
membrane filtration of 100 ml shall be used; in case of water that cannot be filtrated, 1 ml or
further dilution is tested. The results shall be recounted for 100 ml.
3. The determination method according to Czech Standard (CSN EN ISO) 7899-2. In case of water
that can be filtrated, membrane filtration of 100 ml shall be used; in case of water that cannot be
filtrated, 1 ml or further dilution is tested. The results shall be recounted for 100 ml.
4. The determination method according to TNV 757855.
5. The determination method is based on phase separation, with further identification in a specialised
laboratory.
6. The indicator should be determined only in case there is suspicion that there was an abnormal
change in the indicator´s usual value.
7. In case of certain bathing centres, the public health protection body can determine a limit value
different from the permissible value if the difference is caused by natural character of the water.
8. Visual inspection.
9. Visual or olfactory inspection.
10. Spectrophotometric determination with methylene blue.
11. Olfactory inspection.
12. The visible floating pollution involves: rubbish, tar residues, wood, plastics, bottles, packaging of
glass, plastics, rubber or other substances. In case of floating pollution, it is always necessary to
specify the kind and quantity of the polluting subjects.
13. Other substances that are harmful from the chemical or health point of view, such as cyanides,
heavy metals, pesticides etc., are determined only in case there is suspicion they could occur.
14. Only for localities of running waters. Reservoirs are not included into the category fo running
waters.
15. In case of eutrophication, also ammonia ions, nitrate nitrogen, nitrite nitrogen and organic nitrogen
are determined in addition to total phosphorus.
The “target” pollution standards must be achieved by December 22nd, 2012.

1 p.e. (population equivalent) corresponds to the amount of pollution produced: 60 g BOD5 /day.
The minimum number of samples is determined by the water authority.
3)
The water authority shall determine the sample type as follows:
- type A – a two-hour sample coalesced from 8 partial samples of the same volume taken in a 15-minute
interval. This sample type is used only for urban wastewater treated in a treatment facility with delay time
at least 24-hours, for the annual quantity below 200 tons in terms of CODCr coming to the wastewater
treatment plant;
- type B – a 24-hour sample coalesced from 12 partial samples of the same volume, taken in a 2-hour
interval;
- type C – a 24-hour sample coalesced from 12 partial samples of the volume proportional to the flow, taken
in a 2-hour interval.
2)
Particularly hazardous harmful substances must be monitored by using daily coalesced
samples and the daily quantity of wastewater is measured. A simpler monitoring method can
be chosen in case that the quantity of wastewater discharged is smaller than relevant value
specified in Table 2 of this Annex.
Sampling must be equally distributed in time during the year. Samples should not be taken in
extreme conditions such as heavy rain or floods.
