The HARP DPC Project comprises the replacement of 6 tunnel sections of the existing Haweswater Aqueduct (HA), connections to existing multiline siphons between the tunnel sections and associated facilities. It also includes the commissioning and ongoing maintenance of those works for a period of approximately 25 years after completion.
