Looking after the water environment with a ten year capital programme

Yorkshire Water manages the collection, treatment and distribution of water in Yorkshire, supplying around 1.24 billion litres of drinking water each day. We were appointed as its sole Commercial Consultant for its ten year, £2.8bn, capital expenditure programmes in AMP 4 and 5.

Our contribution

We provided commercial management, programme/project management and consultancy services across Yorkshire Water's entire capital programme. This comprised over 3,200 sewerage, wastewater treatment, water treatment and water distribution projects that ranged in value from £30,000 to £100 million.

Our services included:

  • 1.24 billion litres of drinking water supplied per day
  • 63,000 miles of water and sewerage mains - almost enough pipework to circle the Earth
  • 700 water and sewerage treatment works
  • 120 reservoirs

Making the Difference

Some of our key successes include:

AMP 4 in 4 Commercial Close-Out

We developed a risk-based commercial audit and assurance process. This contributed to the efficient financial close-out of 1,800 individual schemes in AMP 4. We achieved an unprecedented level of final account agreement of 91% of all available schemes. This included £400m of large schemes where a transparent gateway process was utilised.

Carbon Accounting

We developed and delivered an industry leading carbon measurement tool including the whole life carbon footprint of the construction programme. Linking this in with cost plans and whole life cost assessments has given Yorkshire Water the ability to deliver energy efficient projects.

Commercial Model

A particular feature of this has been a move from a largely non-competitive regional delivery model to a commercial model where work is effectively 'batched' into mini programmes and alliance teams are required to compete, with past delivery performance a critical and objective evaluation criteria.


Every pound spent with Turner & Townsend on contract administration in AMP4 yielded a £4.80 return, and every pound spent on assurance in AMP4 yielded £7.10 of programme risk reduction.

  • £4.80 return on every pound spent on contract administration in AMP 4
  • £7.10 in programme risk reduction on every pound spent on assurance in AMP4
