Abstract

This document is applicable to all types of water wells, whether for public or private use, abstracting from or injecting water to the groundwater, in a variety of applications. These include potable water abstraction, industrial use, irrigation, dewatering, aquifer recharge, and geothermal applications, or for groundwater observation (see Clause 13). This document does not apply to horizontal wells, groundwater quality monitoring wells in potentially contaminated sites, 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 guidelines for all planning steps from preliminary to final executive project design. A sequential method for designing and dimensioning a well is specified. Based on the hydrogeological conditions and the objectives of the well, a step-by-step process for dimensioning the well is defined. This methodology includes dimensioning for the drilling, filter packs, sealings and screens. Furthermore, selection of appropriate materials, the pump and all other additional well equipment is outlined. With regard to the planning process references are provided for drilling methods, geophysical well logging, well development and pumping tests.
