FIELD: construction.
SUBSTANCE: invention is related to the field of sanitary engineering. Sewage well comprises cast iron set, tray part and bottom. Besides it comprises cone support, vertical pipe that serves as well shaft, telescopic part, sealing ring. Well bottom with tray part serves as foundation for cone support, into which vertical pipe is inserted. At the same time cone support, vertical pipe and telescopic part are made of plastic, and sealing ring is made of rubber. Method for repair of water disposal system wells includes dismantling of well slab with cast iron set. At the same time at well bottom with tray part they mount sewage well, rings of repaired wells serve as curb, space between rings and vertical pipe of new well is filled by sand with layerwise compaction.
