Why contact Southern Water customer service?

– To apply for a water meter

– To get advice on how to save water

– To get help or support with your water meter reading

– To report a water leak

– To get help with blocked drains or flooding

– To request support with flooding clean-up operations

– To get support with frozen or burst pipes

Please note, there are some water pipes that the home owner is responsible for and others that the service is responsible for. As a general rule, home owners are responsible for pipework within the boundary of the property, and Southern Water is responsible for pipes outside the boundary, for example, on the footpath or road.

If you know where the leak is located, you may want to check Southern Water’s ‘Code of Practice’ document – available online – to see if the leak is your responsibility or their responsibility. If the leaking pipe is your responsibility, you will often be suggested to call a qualified plumber to fix the problem.

At the time of writing, their service provides one hour of free ‘detection work’ to help customers find the location of the leak.

About Southern Water

Southern Water is a water and wastewater company supplying services to Hampshire, Isle of Wight, Kent and Sussex. It is parented by Southern Water Capital Limited with headquarters in Worthing, West Sussex. The company was founded in 1989 after the water industry was privatised in the United Kingdom.

The company came about not long after the 1973 Water Act, in which the UK government set about reorganising the country’s water services management. After this, the Southern Water Authority took over water management responsibilities in the South until Southern Water Services Limited took the reins in the late 80s.

Since then, the company has invested a considerable amount of funds into improving its services and now boasts at least 80 water treatment works, more than 300 wastewater treatment works, over 2,000 pumping stations, almost 14,000km of water mains, and more than 39,000km of sewers.

The company gets most of its water from underground water sources, and it may use smaller water companies to reach some of its customers in the region. Today, they supply approximately 521 million litres of water and treats or recycles 718 million litres of wastewater every day.
