General Information
Frequently Asked Questions
CEN/TC 451 is a Technical Committee within the European Committee for Standardization (CEN). It is named "Geothermal and water boreholes" and is responsible for: Standardization in the field of design, environmental aspects, drilling, construction, completion, operation, monitoring, maintenance, rehabilitation and dismantling of wells and borehole heat exchangers for uses of groundwater and geothermal energy. Oil, gas and other mining activities in these fields are excluded from the scope. This committee has published 2 standards.
CEN/TC 451 develops CEN standards in the area of S09 - WATER QUALITY AND WATER SUPPLY - Information technology. The scope of work includes: Standardization in the field of design, environmental aspects, drilling, construction, completion, operation, monitoring, maintenance, rehabilitation and dismantling of wells and borehole heat exchangers for uses of groundwater and geothermal energy. Oil, gas and other mining activities in these fields are excluded from the scope. Currently, there are 2 published standards from this technical committee.
The European Committee for Standardization (CEN) is a public standards organization that brings together the national standardization bodies of 34 European countries. CEN provides a platform for developing European Standards (ENs) and other technical documents in relation to various products, materials, services, and processes, supporting the European Single Market.
A Technical Committee (TC) in CEN is a group of experts responsible for developing international standards in a specific technical area. TCs are composed of national member body delegates and work through consensus to create standards that meet global industry needs. Each TC may have subcommittees (SCs) and working groups (WGs) for specialized topics.
This document covers standardization in the field of geological and environmental aspects, design, construction, operation, monitoring, maintenance and decommissioning of grouted borehole heat exchangers for uses in geothermal energy systems.
This document is only applicable for backfilled and grouted boreholes, it is not applicable for groundwater-filled boreholes.
Direct expansion and thermal syphon techniques are excluded from this document.

The document covers all aspects which are relevant for the design of all kinds of water wells abstracting from or injecting water to the groundwater or for groundwater observation.
This document does not apply to horizontal wells and closed loop geothermal systems. The document defines design requirements of water wells for public and private users in
accordance with groundwater protection goals. It gives guideline for all planning steps from
preliminary to final executive project design.
This document specifies a sequential method for designing a well. Based on the hydrogeological
conditions and the objectives of the well, a step-by-step process of dimensioning the
well is defined. This methodology includes dimensioning of the drilling, filter packs, sealing and
screen. Furthermore, selection of appropriate materials, the pump and all other additional well
equipment is established. With regard to the planning process references are provided to drilling
methods, geophysical well logging, well development and pumping tests.
