In a statement issued on Saturday evening, the utility said that water has been returning to homes in Waterside in the New Forest area of Hampshire

The water company said it was continuing to re-charge the network slowly to prevent further issues, and ustomers could be noticing low pressure and some discolouration at first, which it described as completely normal and temporary.

Southern Water explained that re-charging the network must be done carefully and slowly to prevent bursts, airlocks and discoloured water.

In addition, some customers on the Isle of Wight, in the Ventnor, St Lawrence, Whitwell and Niton areas, could also experience a temporary drop in water pressure, or intermittent loss of supply.

Southern added this was due to the way its network is configured in Hampshire and on the island, as water was moved around the network and the system was re-pressurised. As a precaution, bottled water was being delivered to all customers in the impacted area in the Isle of Wight.

The impact of Storm Ciaran on the company’s Testwood Water Supply Works necessitated the gradually re-charge on the water supply network.

The water company was able to bring 5,300 properties back into supply in the Waterside, New Forest, area Friday and continued working to bring all remaining 13,000 properties back into service by the end of the weekend.

Storm Ciarán combined with recent rainfall caused levels in the River Test to rise dramatically and created unprecedented issues with the raw water quality.

Southern Water said:

“We operate to the very highest legal and regulatory water quality standards. Our monitors detect any issues with the quality of the water coming into our treatment site and will trigger a shut down if there are concerns, which is what happened yesterday. The pictures below were taken yesterday at Testwood Water Supply Works abstraction point and show the challenges we are dealing with. “
