South West Water

Who we are

South West Water are part of the Pennon Group and came into being in 1989 following the privatisation of the water industry. With 1,300 employees we provide a reliable service to the whole of Cornwall and Devon as well as Dorset and Somerset. The resident population of the region is approximately 1.7 million and in peak tourist months the number of people we serve increases to over 2 million.

What we do

We deliver over 340 million litres of water each day through some 15,000km of water mains to 800,000 homes and 70,000 businesses in the South West. About 95% of the water we supply is returned to us for treatment and disposal. We do this through some 14,995km of sewers, around 800 sewage pumping stations and over 600 treatment works, many of which serve a population of less than 1,000 people.
