Water egress (reinstatements)

S11.4.5: If water issues from a reinstatement, the street authority must initiate an investigatory works procedure to determine the cause. Before starting any investigatory work, the authority should contact any undertakers it believes may be responsible for the water egress. Undertakers must cooperate with the authority in its investigation.
S11.4.6: If following the investigation the authority has reasonable cause to believe that water egress has been caused by an undertaker’s operations, remedial measures, at the undertaker’s cost, must be agreed between the authority and the undertaker.
