Drainage
and your proposal
IMPORTANT NOTE - SHARED DRAINAGE RUNS AND UNITED
UTILITIES OWNERSHIPS.
Where
you encounter any drainage or drainage is likely to be affected by your
proposal, from the 1st October 2011 United Utilities
now have ownership / maintenance responsibilities of all private land shared
drainage systems which connect to their sewerage systems and therefore require
access / drainage protection provisions and in some cases formal ‘Building Over
Sewers Agreements’ in place to allow the your work to commence. This applies
where the works are to be undertaken over
or within 3m of the shared pipework.
Prior to the excavations
commencement it is advised your contractor determines the exact positions of
all drainage runs / pipe sizes / pipe depths and positions of all existing
access points and inspection chamber on site and to either side of the
proposals site that will run under or are within 3m of the proposals. Where
shared drainage between adjacent properties is likely to be encountered you are
advised to contact United Utilities Asset Protection Team to determine their
requirements and seek their formal agreement to allowing you to build our there
drainage.
Connections
Any new
drainage connection must be made to the appropriate drain (foul to foul /
surface water to surface water) and
within the site boundaries of the property. United utilities connection
consent will be required if connections are made to neighbouring properties
drainage systems.
