South West Water on Social Media

South West Water is present on Twitter with two active accounts. While one of the account is more focused on company news (@SouthWestWater), customers will probably find the one that is aimed at customer support (@SWWHelp) more useful since it has updates on planned maintenance and outages which helps customers stay informed on any potential interruption to their water supply.

The company is also active on LinkedIn, however that isn't necessarily the best place to get help with queries. This is because the page is more geared towards providing South West Water jobs postings than anything else.
