Updated 'budapest method' for revitalizing radial collector wells and applicability to Belgrade's water supply source

Abstract

Belgrade's water supply source is faced with the complex issue of halting a continuing decline in radial well capacity. It is possible to counteract the problem by replacing worn-out laterals. Past research has provided a basis for undertaking radial well revitalization activities. One of the questions that remained unanswered was how to overcome structural limitations - shallow emplacement of laterals. In Budapest, an innovative revitalization procedure, applying a modified Ranney method, has been used effectively for about 15 years. The laterals are installed below the bottom of the original well shaft and the screen pipes have bridge-like slots. The possibility of applying this method at Belgrade's water supply source is substantial.
