A sewage pipe under a Portsmouth bridge is leaking into the water in Langstone Harbour.
The pipe running beneath A2030 Eastern Road bridge was spotted dripping into the water during a routine inspection.
Southern Water are treating the ‘very small’ drip as a high priority.
With a specialist team set to work to repair the pipe from a barge.
A Southern Water spokesman said: ‘During a routine inspection of the A2030 Eastern Road bridge, Portsmouth City Council Highways workers spotted a drip from one of the sewer pipes under the bridge
‘We immediately investigated and confirmed a small hole in the pipe.
‘The harbour authorities and regulators were informed straightaway.
‘Our Beachbuoy real time alert for recreational water users was also triggered.
'Although the drip is very small, we are treating this as a high priority.
‘A specialist team will make repairs from a barge. As we are tackling the job from underneath, we will not need to place any traffic restrictions on the bridge.
‘We are currently liaising with harbour authorities to ensure our work can be done safely and with minimal disruption to commercial and recreational water traffic.
‘We would like to thank Portsmouth's Highways team for alerting us to this.’
