• Water companies' shares have come under pressure after Britain's regulator opened an enforcement case against the South West Water.
• Investigation on water companies has intensified in past years.
Britain's water regulatory authority Ofwat has come down hard on water companies following violations of rules involving its wastewater treatment works. Due to this, the shares of water companies came under pressure. Pennon Group Plc (LON:PNN) shares significantly fell 6% on Tuesday.
A year ago, Ofwat and the Environment Agency launched an investigation after several water companies admitted to flouting sewage disposal rules.

Pennon Group Plc is accused of making sewage discharges into rivers and other water bodies by paying their executives hefty bonuses and increasing customers' bills.
In March, the watchdog launched probes against several water services companies, including the likes of Wessex Water, Thames Water, Northumbrian Water, Anglian Water, and Yorkshire Water.
Expressing his shock, Ofwat CEO David Black said that the involved companies must aim to resolve any problems with wastewater treatment. Since last year, these investigations have further escalated after the government's U-turn, which has set a limit to the amount of wastewater a company can release.
