United Utilities Water starts pipeline tender process

16 May 2022

The tender process for the Haweswater Aqueduct Resilience Programme (HARP) will get under way with a tender launch event in Manchester on June 8.

HARP, which will be delivered via a Direct Procurement for Customers (DPC) approach for United Utilities Water, involves replacing six tunnel sections – approximately 50km – of the 110km pipeline that carries drinking water from Haweswater in Cumbria to Greater Manchester. It also includes connections to existing multiline siphons between the tunnel sections and associated facilities, and the commissioning and maintenance of the works for approximately 25 years.

The contract will include construction work for bridges, tunnels, shafts and subways, and tunnelling works.

Companies must register their interest in the launch event at [email protected] no later than midday May 30.

In December last year HARP was named the Ground Investigation Project of the Year at the 2021 Ground Engineering Awards. The team comprised United Utilities, Jacobs, Mott MacDonald, British Geological Survey and Wardell Armstrong.

By running the ground investigations concurrently across the six tunnel sections, the team delivered the ground investigations in under two years. The team also optimised the technical output of every borehole to minimise the number of boreholes required, while also maximising the value of the information obtained.
