The problematic issues of operation of water wells: low service life, insufficient maintainability and reduced specific flow rate are highlighted. The circulation reagent treatment of water intake well filters by the swabbing method is considered. The design of the installation for processing the filter section and the technological scheme of reagent regeneration by the method of linear swabbing in a closed chamber are presented. A method for calculating processing modes depending on the design parameters of the submersible device, the speed of the swab, the degree of clogging and filtration parameters in the gravel dressing of a water well describes. Based on the initial data,  an example of calculating the duration of the reagent treatment of the filter section using hydrochloric acid as a reagent is considered.
