Scope

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.
