The Water Corporation is working on the Infill Sewerage Program  in parts of Castletown. Over 123 Lots will benefit from  conencting to main sewer as part of the Esperance infill sewerage project in parts of Castletown.This work allows properties using septic tanks to decommission them and connect to the wastewater system. This removes potential public health and environmental risks and supports the development of residential areas.  Traffic management will be in place as required to direct pedestrians, cyclists and vehicles safely around work areas. Work is expected to be completed by the end of this year. For more information visit
