Installation of water supply wells requires a clear understanding of the geological profile and hydrogeological characteristics of the target water bearing horizon. This information is used to develop a specification for the well screen and annulus backfilling including placement of appropriate seals to isolate the target stratum from risk of surface contamination. During installation cleanliness including disinfection of drilling tools is required. Following installation, wells will need to be developed prior to pump installation and test pumping. WJ has the experience and capacity to design, install, test pump and suitably equip water supply wells up to 200 m depth and 450 mm finished bore.
