Cappagh has been undertaking sewer connections work for over twenty years working both as a framework agreement contractor for Thames Water and working directly for property developers, contractors, house builders and commercial businesses.
After many years of undertaking sewer connections on a one-off basis, Cappagh were awarded the Lot 7 Small Network Contracts framework agreement by Thames Water. As well as wastewater repairs and maintenance work, this agreement required Cappagh to undertake sewer connections in South London for Thames Water.
We carried out this contract for the entire AMP4 (OFWAT Asset Management Plan) period and were then successful, through our joint venture CMjv, in securing the sewer connections work for Thames Water for a further five years as part of the Lot C2 Developer Services contract in South London. As well as carrying out all of Thames Water’s sewer connections in South London, we also continue to undertake sewer connections, sewer upsizing and diversions for other customers.
For all of the sewer connection work we undertake, we are responsible for the planning / scheduling of all works, pre-inspection / enabling, liaising with Highway Authorities and other stakeholders such as the emergency services, local businesses and residents, raising streetworks notices / permits, arranging parking bay suspensions, road closures and TfL shut-outs, identifying and organising traffic management requirements, backfilling and final reinstatement.
We offer an end-to-end service and can take your sewer connection from design to completion with very little involvement from the client. Where required we can design the connection a well as obtaining consent for the connection from the asset owner and ensuring that the works are carried out to adoptable standards. We undertake in the order of 75 sewer connection projects per annum ranging in value from just £5k to £2m with a recent example being the connection for The Shard at London Bridge Quarter, the tallest building in Western Europe.
For this new building, we were required to construct a shaft and heading at a depth of 4.3m, the construction of a 1200mm diameter manhole and the connection itself was 300mm diameter in to a brick sewer which involved core drilling.
We are happy to work to a fixed price quotation for sewer connection projects due to our extensive knowledge and experience of the work and processes involved, which enables clients to have cost certainty from the outset.
