02.11 Water Conservation Districts
(Edition 2001)
Overview
The drinking water needs of Berlin are met primarily by groundwater. The drinking water supply is
managed by the Berlin Public Water Companies. Water supplies are partially obtained as bank filtered
water: surface waters filter through the soil and are withdrawn by extraction wells near the banks).
Some surface water is diverted into groundwater recharge plants to percolate into groundwater, which
will then be withdrawn for use.
Fig. 1: Principles of Groundwater Production (AHU 1991)
There are also a number of smaller production plants, the private sector water supply plants, which
withdraw groundwater for private sector purposes, mostly industrial, or withdraw groundwater for public
facilities.
Construction increased considerably after the unification of Berlin in 1990. Groundwater retention is
practiced during construction when groundwater is withdrawn. This occurs according to construction
activity at various locations and in variable amounts. Especially deep and/or large construction projects
use the trough construction method which spares groundwater. This method requires the withdrawal of
only small amounts of water.

(including Stolpe Waterworks)
The restructuring of groundwater use after 1990 resulted in essential changes to the groundwater
system of Berlin. Demands on drinking water in the city decreased, in western areas by 27 percent and
in eastern areas by 62 percent. This resulted in an overall increase of the groundwater surface,
especially for the waterworks supply wells in the southeast. Thus, due in large part to the natural
pleistocene watercourse structure in Berlin, the groundwater levels rose by 0.5 to 1 m, with up to 3 m
near the waterworks.
Where previously the Berlin water companies utilised sixteen waterworks to supply drinking water, in
the 1990's only nine were used. In order to decrease the risk of impurities in the groundwater, the wells
lie in water conservation areas where certain usage is strictly prohibited.
Legal Principles
As a framework for regional legislation, the Federal legislature have provided the "Gesetz zur Ordnung
des Wasserhaushalts (Wasserhaushaltsgesetz - WHG) - water supply regulations. §19 The WHG
forms a basis for the regional authorization of water conservation areas.
§ 19 Water Conservation Areas
(1)
as far as circumstances permit, Water Conservation Areas can be established,
1. to protect the present and future public water supply from disadvantageous effects or
2. to enrich the groundwater or
3. to prevent groundwater damage resulting from precipitation and the loss of nutrients or the
absorbtion of impurities from pesticides or fertilizers.
(2)
In the Water Conservation Areas
1. damaging actions can be prohibited or severely restricted and
2. special measures can be taken to prevent damage resulting from the actions or rights of
property owners and users. The obversation and protection of soil and groundwater is an integral
part of these measures.
Other regulations of the legislature have only an indirect effect on the procedures. Of note here are the
"Gesetz über Abgaben für das Einleiten von Abwässer in Gewässer (Abwasserabgabengesetz AbwAG)" and the "Verordnung über Trinkwasser und über Wasser für Lebensmittelbetriebe
(Trinkwasserverordnung - TrinkWV).
Together with the Federal legislature, the Berlin Water Rights policy which summarises the laws, legal
ordinances and administration regulations, forms the basis for the establishment of water conservation
areas (WSG).
In conjunction with the partial privatisation of the Berlin water companies (BWB) in the year 2000, the
new (Berliner Wassergesetz -BWG) § 37 was established, and proposes that all waters needed for
Berlin's public water supply should be taken from the Berlin region.
To assist in the implementation of the WSG proposals for
§ 22 Wasserschutzgebiete (Water Conservation Areas)
(1) Water conservation areas are fixed by regulation of the senate. The protection regulations are to
be marked in the ordinance. Zones with different protection regulations can be fixed. (...)
(2) In the establishment of water conservation areas, the local authorities and local public bodies
should be involved.
(3) A hearing procedure is a necessary part in the establishment of a water conservation area.
Decisions and plans are to be publicized in the official Berlin "Amtsblatt". The following must be
observed,
1. Plans, (drawings, proofs and descriptions) showing the full scope of the water conservation
zones and the proposed protection regulations should be available for one month and
2. Objections to the proposed measures can be raised up to two weeks (at the latest) from the end
of the publication period... (...)
2
In addition, the laws regulate the division of standing waters and rights pertaining to property
ownership, use of water and official responsibility. Furthermore, the maintenance and building of
embankments and constructions at or in standing waters.
Water Conservation Areas
After the preplanned closures in 2001 of the Johannisthal und Jungfernheide works, the Berlin water
companies still operate nine waterworks, whose catchment areas are protected by the following
ordinances.
The Berlin water law distinguishes three legal qualitative definitions of protected areas:

New and old area protection ordinances from §22 Abs.1 the BWG,

and water conservation areas from § 22 Abs.5 the BWG.
From §22 Abs.1 the BWG were remitted the following protection ordinances by the Senate Department

Criteria for the scope of Water Conservation Districts
Conservation zones are set on observing the relationship between protection regulations and the
distance from the water source. Taking the increased interest in conservation and protection of
groundwater into account, drinking water wells are covered by zones with stronger protection
regulations. For the individual WSGs, different criteria for the demarcation was assessed on the basis
of the heterogeneous legal status (hydrology, geology, local conditions, settlement).
1946 Allied Ordinance
Water conservation zones in areas regulated by Section 4 of the Magistral Ordinances of 8 October
1946 were determined use limitations. This ordinance proceeded from an order of the Allied
Commandant of Berlin, valid for all Berlin. The conservation zones are divided into a narrow
conservation zone(zone II) with a radius of 100 m around extraction wells, and into a wider
conservation zone (zone III) with a radius of 500 m. The captation area (zone I) is defined by the water
conservation area ordinance with a radius of 10 m around the wells. In case of well galeries the areas
will be connected.
The Spandau Waterwork is still protected by this ordinance. This ordinance will be replaced by a water
conservation district regulation according to the Berlin Water Laws in the next few years.
Water conservation area ordinance
The regulations enacted until further notice are divided into two groups.
Under the old Regulations the differentiation of the wider protection zone III was not determined.
(Beelitzhof, Kladow, Tiefwerder (issued between 1975 and 1987)). After 1988, protection zone III was
re-defined into IIIa and IIIb.
Under the new Regulations, the Isochronic concept (comp. fig. 3) is the measuring principle used.
The area size of the conservation zones is measured according to the DVGW Regulatory Rules
"Guidelines for Drinking Water Conservation Districts" (DVGW-Regelwerk "Richtlinien für
Trinkwasserschutzgebiete"). The areal extent of Zone I is generally at least 10 m surrounding the
extraction well. Zone II reaches from the border of Zone I to a line at which groundwater requires 50
days to seep into the extraction well feed area. Zone III comprises the area from the outer border of
Zone II and the border of the subterranean water catchment area. If the catchment area is larger than
2 km, a subdivision into Conservation Zone III A and III B is possible. Local hydrogeological conditions
must be considered in the determination of conservation districts; a universal pattern may not be
applied. To get a clear fixing of the areas the real scope follows existing site or land borders or clear
visable terrain marks.
The rigid radius drawn around the extraction well does not take into account the differing hydrological
and geological conditions in the catchment areas of the individual water withdrawal sites. The
isochronic concept determines the size of water conservation districts and their geometric forms in
4
hydraulic terms: from the flow time of water to the removal site. Lines of identical flow time are called
isochrons.
Flow times at the removal sites for determining the conservation district borders:

conservation zone II: 50 days

conservation zone IIIa: 500 days

conservation zone IIIb: 2.500-3.500 days
The determination of the isochrons, and thus the conservation district borders, proceed from
hydrogeologic examinations of a given area. A regional groundwater flow model is developed for this
area. The goal of the concept is to have sufficient time for damage control should soil (and/or
groundwater) be contaminated.
Fig. 3: Example for Definition of a Water Protection Area According to the Isochronic Concept
The flow velocity of groundwater is indicated by the length of the arrows. The longer the arrow, the
higher the flow velocity.
Use limitations within conservation districts were supplemented and extended in the course of revising
the Water Conservation District Regulations according to the isochronic concept.
Statistical Base and Methodology
For the statistical documentation of the regions, no uniform basis was available. As far as water
conservation area ordinances were concerned, atlas supplements in the scale 1:5000 were available.
Information concerning wells was recorded and documented with reference to the demarcation from
iso-distances, (instigated after the 1946 allied ordinance). Ordinance information for other areas was
taken from the Berlin map 1:5000 and then digitalized. The precision given for the Berlin region is due
to the availability of the map in scale 1:5000. In contrast, information for the conservation zones in the
Brandenburg region had to be taken from smaller scale maps, an exact statement for single sites is not
possible.
The project essentially used the graphic software "Mercury" of the Fa. CGM. Basis was the "Karte von
Berlin 1:5000 - screen data (K5 RD) - " the Ministry of Urban Development, Dept. III.
The selected map scale of 1 : 50,000 does not allow Berlin Public Water Companies wells to be
depicted individually, but only as well galleries. The depiction of Conservation Zone II in the former
West Berlin and the captation zone (Zone I) are also missing.

Map Description
Excepting Buch, the nine waterworks of the Berlin Public Water Companies Spandau, Tegel,
Tiefwerder, Beelitzhof, Kladow, Wuhlheide, Kaulsdorf and Friedrichshagen are located in the WarsawBerlin pleistocene watercourse or the Havel channel.
The Stolpe Waterwork is located in Brandenburg. It is operated by the Berlin Public Water Companies
and serves the drinking water supply of Berlin and a few nearby communities in the state of
Brandenburg. The conservation districts of the Staaken, Eichwalde and Erkner Waterworks, which
serve communities in the vicinity of Berlin, are located both inside and outside the city boundaries.
Due to the large number of waterworks both in the city area and on the outskirts, a considerable
proportion of urban areas are under protection. Berlin's has a total surface area of approx. 890 km²,
with water conservation zones accounting for approx. 26 %.

Withdrawal Amounts
In their dealings with 18 Water Authorities of the Berlin region, the Berlin water companies have agreed
eight drinking water supply contracts for the Brandenburg district. In the year 2000, these authorities
supplied 3.3 Million cubic metres of drinking water to over 85,000 Inhabitants.
The drinking water is treated at the waterworks and distributed over a 7,800 km long supply network.
The average age of the Berlin water system is 50 years, the oldest water-pipes being about 130 years
old. For private consumers, Berlin has approximately 250,000 house connections from the general
supply network, and approximately the same number with built-in water meters.

Tab. 3: Groundwater Withdrawals 1913, 1990 resp. 1989, 1995 and 1999
According to not jet reached data from groundwater retention at construction sites the total amount of withdrawals for
2000 can not be presented.
Since the beginning of the public water supply, the withdrawal amounts of the Berlin water
companies has risen steadily. There was a clear decline in withdrawal amounts after the 2nd. world
war. Later, while in East Berlin there was a continuous increase right up until 1989, the middle of the
70s saw withdrawal amounts in West Berlin settle down to a constant level.
Fig. 4: Groundwater Withdrawal Amounts of the Berlin Public Water Companies 1960 - 2000
Figures are for withdrawals of raw water and refer to (including Stolpe Waterwork) the water management year. The sum for
1973 includes 8.2 mil. m³ for filling Teufelssee lake in Grunewald. Figures include Jungfernheide Waterwork amounts mainly
used for restoration of groundwater and not for the drinking water supply: 1990, 5.7 mil. m³; 1995, 4.1 mil. m³; 1996, 3.4 mil. m³.
Figures for the Friedrichshagen Waterwork 1996 water management year include 1.8 mil. m³ from Gallery A which were
discharged to the Münchehofe clarification plant; and 158,040 m³ of a Gallery I well discharged to the Krumme Lake biotope.
This water was not used for the drinking water supply.
Since 1989 a strong reduction of ground water withdrawal can be observed. In 1989 the ground water
withdrawal amounts of the Berlin Water companies stood at 358.4 Mio. m³ (incl. Stolpe Waterworks).
In the year 2000, 222.3 Mio. m³ of raw water was withdrawn, the withdrawal volume of the BWB sank
40 %. The average daily water withdrawal amounted to 610,000 m³, with a maximum of 1.14 Mio. m³
per day possible. The reasons for this reduction in raw water use lies in the closure of many industrial
concerns in East Berlin, the pricing policy of the water businesses (increased water prices) as well as
an improved technology, allowing consumers to make savings in private consumption.
The water companies calculate that water consumption will also sink in the future, although more
slowly than in the 1990's. In the year 2000, private consumption was 124 liters per head per day,
whereas 10 years ago this stood at 140 liters. An even bigger reduction in consumption has come from
industry, where water demands have virtually halved since 1990.

Fig. 5: Groundwater Withdrawal Amounts According to Use in West Berlin from 1963 - 2000
Since 1987, construction groundwater retention for restoration and redevelopment measures have
been included. The figures are for raw water withdrawals and refer to the water balance year.
The amount of the total withdrawal of private water supply plants is also declining. Figure 5 portays the
withdrawal of groundwater by private water supply plants for West Berlin. In 1989, private sector water
supply plants removed 41.6 million m³ (17.3 million m³ of it in the eastern part of the city), in 2000 it
was 11,4 million m³ for the whole city. This water was used as drinking, operating, and cooling water,
and for plants, lawns and green areas. The plants which also remove for drinking water are specially
monitored to maintain a water quality fit for human consumption. There is a tendency to close such
plants, primarily for economic reasons, and to take water from the public network.
Also the number of groundwater retentions at construction sites has reduced from 1011 in 1995 with a
withdrawal amount of 34,2 million m³ to 434, with 12 million m³ in 1999 (data from 2000 are not
available because of late data report).
Groundwater Balance
The goal of water economy is to maintain a groundwater balance. That means only so much
groundwater should be removed as can be recharged. If removals exceed recharge, the groundwater
reservoir will gradually empty; the groundwater level sinks. The West Berlin groundwater level sank
strongly in 1950 - 1975, due to large withdrawal amounts of the Berlin Public Water Companies, private
sector water supply plants, and groundwater retention at construction sites. The groundwater level has
been rising since the mid-70's. This is caused by a reduction in withdrawal amounts of groundwater by
private sector water supply plants, and by a reduction in groundwater removals, as well as an increase
in groundwater returns, at construction sites.
The Public Water Companies established three groundwater recharge plants in order to increase
groundwater. These plants were necessary because precipitation and natural bank filtration from
surface waters were insufficient to compensate for and balance out groundwater removals. Surface
water is discharged in the vicinity of groundwater removal wells, into shallow earthern basins, ponds, or
pits. This water then percolates into the groundwater. Natural percolation basins include Kuhlake in the
Spandau Forest and the Grunewald chain of lakes (Grunewaldseenkette), which are located in the
catchment area of withdrawal wells.
The processing facilities of the Spandau Waterwork receive surface water from the Havel river,
process it mechanically and chemically, and then discharge it for percolation at Kuhlake, Kreuzgraben,
and the connected channel-pond system. After lake water from the Tegeler See is processed, it is
discharged through micro-sieve facilities for percolation at Baumwerder island and at Saatwinkel. The
Beelitzhof Waterwork purifies Havel river water in a phosphate elimination facility for discharge into the
Schlachtensee lake. This water eventually enters the Grunewald lakes. In the area of the Stolpe
Waterwork, Havel river water is dammed onto Havel meadows and percolates.
Groundwater recharge plants injected 51.3 Mio. m³ of prepared surface water for percolation in 2000.
Besides "true" and manmade recharged groundwater, a considerable portion of water withdrawn by
the Public Water Companies comes from bank filtered water. Wells in the vicinity of surface waters
produce cones of depression, and water from the bank areas of the Havel, Dahme and Spree rivers
flow into them. The proportion of bank filtered water in the total withdrawal amount of each well gallery
depends on the distance of the well from the surface waters. An average of 50 % of the removals of
the Berlin Public Water Companies has been assumed.
Groundwater Management
The dramatic reduction in demands on groundwater especially in the neighbourhood of the recently
de-commissioned Waterworks, has resulted in groundwater levels rising by up to 3m. This is especially
so in the pleistocene watercourse region of southeast Berlin where areas have a high level water table.
This has resulted in residential estates being plagued by water-logged cellars, eg. Rudow in the 1990's.
In July 2001, in order to achieve groundwater states which allows settlement areas without water
damages and as a reaction to the spatial unequal development of water demand inside Berlins, the
Berlin senate made the following decisions:
8
In the long term, 50 percent more groundwater should be available for the public water supply in the
eastern half of the city, to be taken from the regional network where consumption allows. The
groundwater supply to southeast Berlin should be increased to a future 90 Mio. m³ per year from the
present 60 Mio. m³ per year. After repair and rennovation, the Berlin water-pipe network should supply
drinking water to the west of the city.
Through the additional groundwater withdrawal for drinking water production in the neighbourhood of
the waterworks in southeast Berlin, the increase of the groundwater level can be stopped and
consistent groundwater states for residential areas can be guaranteed.
As a consequence of the increased drinking waters production in southeast Berlin and in order to
safeguard public drinking water supplies, the Berlin water companies must cut production in the
western half of the city by 30 Mio. m³ per year. Thus increasing groundwater reserves in the proximity
of the waterworks where production is reduced, but also spreading the problems of water-logging from
east to west. In order to counteract this, the levels of groundwater concentration (through the
infusion of purified surface water into the subsoil) should be controlled to reduce the problem and
achieve an approximate levelling of groundwater states throughout the city.
The momentarily de-commissioned Jungfernheide waterworks offers the BWB an immediate
reduction of drinking water production in the western half of the city. To achieve a long term increase in
production levels in the eastern half of the city, the local waterworks must be restored and modernised
accordingly. Re-development is due to start shortly at the currently de-commissioned Johannisthal
waterworks. These measures are scheduled for completion by 2009 at the latest.
In the meantime, work should be intensified to eliminate subsoil pollution in the catchment areas of the
Johannisthal and Wuhlheide waterworks. Through the controlled increase of groundwater reserves,
redevelopment can be accelerated on the large-scale Spree project (contaminated waste disposal
sites in Niederschöneweide, Johannisthal und Adlershof).
