Waste water network repairs and maintenance to sewers, manhole covers and private sewers

Undertakings:

This contract involves the repair and maintenance of Thames Water’s Waste Water Network in North & South East London and includes manhole cover and frame replacement, repair of rising main bursts and critical and non-critical collapses, excavation for sewer repair, pipe laying, concreting, brickwork, metalwork and other related services, working in both public highways and on private land. We regularly construct complex civil engineering works such as deep shafts and tunnels to enable repairs to deep sewers in locations ranging from Central London to rural Hertfordshire and Dartford in the South East. We have been delivering this work in the North London and Home Counties area for the past 8 years, initially through the entire AMP 4 period, and currently as part of the AMP 5 period.

Customer service is extremely important on this contract, as our staff regularly work on the water customer’s private property. We understand that we can make a positive impact on water company SIM performance, so all of our staff are trained in customer service and strive to carry out the works with minimum disruption. In October 2011, Thames Water took ownership of a large private network as part of a statutory transfer, which increased their network by 40% and this has significantly increased works in customers’ properties.

WNS North London

We work in the public highway in high profile areas such as the West End, The City of London and Canary Wharf, and throughout North and South East London.

We have over 30 work teams engaged on this contract and plan and dispatch all the works from our Lea Bridge Road site office, where we have a back office team that manages the works. We manage approximately 9,000 individual road opening notices per annum on this contract and work closely with our in-house traffic management business, BTMS, and the local authorities to ensure that we minimise disruption to residents and road users for the duration of the works. We run a 365 day 24 hour call-out service for emergencies, and have a number of first respondent ‘make safe’ teams who will attend collapsed drainage sites to assess the damage, secure the site and enable a repair.

Health and safety continues to be a major focus on this contract, particularly as the work involves the construction of shafts and tunnels in confined spaces. The work also involves a high level of reactive work in a busy urban environment, which makes health and safety planning and careful assessment of risk very important. These factors require our workforce to be well trained and experienced in working in confined spaces and within deep excavations and we place a particular emphasis on safe digging practices.

We work hard to minimise environmental impact to the areas we work in (including areas designated as SSI’s), by working to strict guidelines and environmental plans.
