Input Formula

Based on § 3, No. 3, of the Water Protection Act of 24. August 1965 (Bundesgesetzblatt I, p. 1225), as amended by the Introductory Act on the Law on Administrative Offences of 24. May 1968 (Bundesgesetzbl. 503), the Federal Government, with the approval of the Federal Council, decrees: Non-official table of contents

§ 1 Scope of application

The provisions of this Regulation shall apply to wells and source versions of individual plants to be operated independently for
Coverage of the vital need for drinking water,
Supply of water in the water in the indispensable scope,
Coverage of demand for extinguishing water
are built or converted according to the Water Protection Act. They do not apply to wells and source versions of the central water supply. Non-official table of contents

§ 2 General requirements

Wells and source versions are to be built according to the generally accepted rules of technology or to restructure, unless otherwise provided for in this Regulation. Non-official table of contents

§ 3 Construction, building materials and components of wells

(1) Construction materials and building materials must be so designed that: they resist electrolytic and chemical agents for as long as possible. The construction of the wells must correspond to the hydrogeological conditions.(2) Brunnenshaft and Brunnenkopf must be manufactured in such a way that the water is not affected by external action, in particular by radioactive precipitation or biological or chemical warfare agents, for its intended use. can be.(3) The type and design of the conveyor system shall be determined by the hydrogeological conditions and the provision of water. With sufficient ground water level and a water supply up to 3 cbm/h, hand pumps are to be used to a large extent. In all other cases, the conveyor system shall consist of a pump and a motor; deviations may be provided in justified cases. According to the design, a hydrant with a key and a standing tube can belong to the conveyor system. For pumps with an electric motor, the connection for an emergency power unit or an equivalent device is to be provided in addition to the mains connection.(4) The immediate vicinity of wells shall be fixed in such a way as to be accessible at any time and to allow the water of precipitation to flow off above ground. If pumps with internal combustion engines are used, the standing space must be selected or prepared in such a way that mineral oil can neither seep out nor enter the water to be discharged.

§ 4 Special requirements for drinking water emergency wells

(1) New wells to be built that are used to supply drinking water , as a rule, must be built as well. You must consist of the following parts:
Bottom tube with bottom, filter tube, top tube, Brunnenkopf, Conveyor line and well shaft with day-water-tight shaft cover.
derogations may only be provided in justified exceptional cases. Provision should be made for conveyor systems in accordance with § 3 (3).(2) Rebuilding wells intended for the supply of drinking water must have at least one day-water-proof cover and a conveyor system in accordance with § 3 (3).

§ 5 Proof of strength

The components of a well must satisfy the following requirements:
It is a circular cross-section with as small a diameter as possible.
One after another, the following load cases:
a uniformly distributed vertical load on the ground level of 200 kN/sqm,
a uniformly distributed external pressure (circular ring pressure) of 150 kN/sqm.
The circular ring cross-section must be "p" (kN/qm) under a horizontal in one direction, either
a deformation of 1% of its diameter without exceeding the allowable voltages receiving or

Brunnenpipes and BrunnenkopfThe pipes used as well elements are to be measured one after the other for the following load cases:
an evenly distributed external pressure (circular ring pressure) of 200 kN/qm
under a horizontal bottom pressure "p" (kN/qm), a deformation of 1% of the diameter must be taken without exceeding the permissible stresses

§ 6 Construction, building materials, and components of source versions

(1) Source versions may only be will be built or converted if a sufficient swelling is guaranteed.(2) Construction and building materials of source versions must be based on the type of source and in accordance with local conditions. The source versions shall be such that they resist electrolytic and chemical agents for as long as possible.(3) Source versions shall contain the components required for water capture and water release. The source versions and the collection shaft must be sealed against under-and above-ground contamination in accordance with the intended use of the water. A top layer of at least 3 m should be above the leachate line. Excess spring water must be able to flow unhindered and without damage to the environment.(4) A pump system is only to be maintained if it is necessary for water conveyance for a necessary pressure of the water at the distribution point. The type of the pump system depends on the source charge and on the delivery capacity of the feed line to the distribution point. For sources with a bed of up to 3 cbm/h, hand pumps are largely to be used, in all other cases motor pumps. For pumps with an electric motor, the connection for an emergency power unit is to be provided in addition to the mains connection.(5) The immediate vicinity of the water extraction point shall be fixed in such a way as to be accessible. In the case of pumps with internal combustion engines, the parking space must be prepared in such a way that mineral oil can neither seep out nor enter the water to be discharged.
