G 1030 "Requirements on the quality and organisation of operators of plants for the manufacture, transport, treatment, conditioning or feed-in of biogas"
Version 12/10, EUR 20.01 (DVGW members), EUR 26.68 (non-members), Available in German only
Preamble
This Code of Practise has been elaborated by the "TSM" Project Group within the Steering Committee on "Gas supply" in cooperation with representatives of the Fachverband Biogas e. V. (Biogas Technical Association, a registered association), the Deutsche Vereinigung für Wasserwirtschaft, Abwasser und Abfall e. V. (DWA, German Association for Water, Wastewater and Waste, a registered association) and of the authorities.
The second law on the revision of the Energy Industry legislation obliges companies operating gas supply installations to meet certain economic, technical and staff requirements so as to ensure the highest possible degree of safe and secure, cost-efficient and environmentally compatible energy supply. Within the meaning of § 3 Par. 15 Energy Industry Act (EnWG), energy installations are installations for the manufacture, storage, transport and delivery of energy.
This Code of Practise defines the plant and process organisation requirements to be met by operators of plants for the manufacture, transport, treatment, conditioning or feed-in of biogas.

Version 12/10, EUR 10.37 (DVGW members), EUR 13.83 (non-members), Available in German only
Addendum has been elaborated by the "Plastic materials in gas and water supply systems" Project Group at the behest of the Technical Committees on "Gas distribution" and "Water supply system components". It contains various amendments and additions relating to the scope of testing described in DVGW Code of Practise GW 335-A2 of November 2005, including the amendments shown on the February 2008 correction sheet. As the requirements have not been subject to any fundamental changes, this Addendum applies in conjunction with the November 2005 version of DVGW Code of Practise GW 335-A2, superseding the February 2008 correction sheet. No objections have been made to the draft version (yellow paper); the current final version (white paper) therefore remains unchanged.

W 120-2, draft version "Qualification criteria for drilling and near-surface geothermal plants (downhole heat exchangers)"
Version 12/10, EUR 20.01 (DVGW members), EUR 26.68 (non-members), Available in German only
In recent years, recurring damage during the construction of near-surface geothermal plants has shown that enterprises constructing such plants must be obliged to meet special requirements applying to both the qualification of their staff and technical equipment. In the meantime, heat pump manufacturers, too, have realised that they can keep up the positive image of near-surface geothermics only if the actual plants comply with the previously defined design principles, and the work has been executed by qualified staff using appropriate equipment. Successful implementation of these requirements can be achieved by employing a suitable quality assurance system comprising a qualification procedure to monitor and certify enterprises in respect of the two last-mentioned criteria on the one hand, and by specifically monitoring plant construction on the other. Above and beyond the quality aspects mentioned above, care must be taken to ensure groundwater protection at all times during the construction of downhole heat exchangers, especially so if plants are constructed in water protection areas. W 120 Part 2 sufficiently covers all requisite criteria and requirements applying in this context. The yellow paper at hand of DVGW Code of Practise W 120 Part 2 that has been submitted by the DVGW together with figawa e. V. (Federal Association of the Companies in the Gas and Water Industries, a registered association) the Federal Geothermal Association GtV e. V. and the Bundesverband für Wärmepumpen BWP e. V. (Federal Heat pump Association) is a draft version describing a qualification procedure for near-surface geothermics whose comprehensive provisions are designed to considerably enhance quality assurance. The BWP e. V. downhole heat exchanger seal of quality has been adopted in the course of this cooperation. It is now up to the technical public to develop this draft version further in the course of the objection procedure with the objective to create a certification procedure able to withstand critical scrutiny that the entire industry is willing to accept.
Objection period ends on 30/04/2011
