Severn Trent Plc, the U.K.’s second biggest water company, said full-year earnings were consistent with its expectations as it continues to benefit from higher customer prices.  Profit before interest and tax for water and sewage probably rose between 10 percent and 12 percent from 413 million pounds last year, the Birmingham, England-based company said today in a statement. U.K. water regulator Ofwat has allowed Severn Trent, which supplies more than 8 million people in western England, to raise water and sewage prices by 5.9 percent from April 1 to pay for customer service and infrastructure improvements. The utility is awaiting the outcome of charges for reporting false leakage data.  Severn Trent said in November that it can’t estimate the impact of any fines resulting from three charges by the Serious Fraud Office that it misreported leakage data between 2000 and 2002. The alleged fraud violations were committed under previous management and no individuals will be charged, the company said at the time.
