On the basis of § 3 No. 3 of the Water Protection Act of 24 August 1965 (Federal Law Gazette I p. 1225), as amended by the Introductory Act on the Administrative Offences of 24 May 1968 (Federal Law Gazette). 503), the Federal Government, with the consent of the Federal Council, prescries: Unofficial table of contents

§ 1 Scope

The provisions of this Regulation shall apply to wells and source versions of individual installations to be operated independently.

1.

To meet the vital needs of drinking water,

2.

Supply of operating water to an indispensable extent,

3.

Coverage of the needs for Löschwasser

to be built or converted under the Water Protection Act. They do not apply to wells and source versions of the central water supply. Unofficial table of contents

§ 2 General requirements

Wells and source versions shall be constructed or converted in accordance with the generally accepted rules of technology, provided that this Regulation does not determine otherwise. Unofficial table of contents

§ 3 Construction, building materials and components of wells

(1) The construction and construction materials of wells must be such that they resist electrolytic and chemical agents for as long as possible. The construction of the wells must correspond to the hydrogeological conditions. (2) The well shaft and the well head must be produced in such a way that the water for its intended use is not affected by external action, in particular by radioactive waste. (3) The type and design of the conveyor system are 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 equivalent device shall be provided in addition to the mains connection. (4) The immediate vicinity of the well shall be fixed in such a way that it can be moved at any time and that the resulting Precipitation water can 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-Notbrunnen

(1) New wells intended for drinking water supply must normally be built as well. They must consist of the following parts:

Bottom tube with bottom, filter tube, top tube, well head, conveyor line and well shaft with a waterproof shaft cover.

Derogations may only be provided in duly substantiated exceptional cases. Provision should be made for conveyor systems in accordance with § 3 (3). (2) Wells that are to be redesigned and intended for the supply of drinking water must have at least one day-water-proof cover and a conveyor system according to § 3 (3).

§ 5 Proof of strength

The components of a well must meet the following requirements:

1.

Well shaft

a)

A circular cross-section with as small a diameter as possible is to be selected.

b)

The following load cases shall be applied in succession:

aa)

a uniformly distributed vertical load of use in a terrain height of 200 kN/sqm,

bb)

A uniformly distributed external pressure (circular ring pressure) of 150 kN/sqm.

c)

The circular ring cross-section must either be under a floor pressure "p" (kN/qm) acting horizontally in one direction.

aa)

-a deformation of 1% of its diameter without exceeding the permissible stresses, or

bb)

for a bending moment

 a (deep) a (high) 2 
 M = p (deep) o --------------- (kN x m) 
 2   

, or

cc)

A peak load of

 a (deep) a (high) 2 x Pi 
 P = 1,7 x p (deep) o x --------------------- (kN/m) 
 2 x a (deep) i   

record.

In this case: P (deep) o = 50 (kN/qm) a (deep) a = outer radius (m) a (deep) i = inner radius (m).

2.

Fountain pipes and well-head The pipes used as well elements are to be dimensioned one after the other for the following load cases:

a)

A uniformly distributed external pressure (circular ring pressure) of 200 kN/qm

b)

Under a soil pressure "p" (kN/qm) acting horizontally in one direction, a deformation of 1% of the diameter must be able to be absorbed without exceeding the permissible stresses.

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

(1) Source versions may only be built or converted if 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 must be designed to withstand electrolytic and chemical agents for as long as possible. (3) Source versions must contain the components required for water collection 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 required 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 must be fixed in such a way that it is 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.
