SEVERN TRENT PLC

INTERIM MANAGEMENT STATEMENT

21 July 2009

Severn Trent today publishes its interim management statement for the period
from 1 April 2009 to 21 July 2009.

The Board can confirm that trading has been in line with its expectations and
prior guidance. No new material trading events or transactions have occurred
during the period.

Sales prices in Severn Trent Water have increased by 5.3% (including inflation)
from 1 April 2009. The decline in consumption across our measured income base
has continued at similar levels to 2008/09; we estimate this will impact
revenues by around £15 to £20 million in the current financial year.

We expect that net capital expenditure (UK GAAP after deducting grants and
contributions) for the year will be around £610 to £630 million. The level of
net infrastructure renewals expenditure included in this figure (charged to the
income statement under IFRS) is anticipated to be around £100 to £110 million.

Severn Trent will announce its interim results on 24 November 2009.

Footnotes:

This document contains certain "forward-looking statements" with respect to
Severn Trent's financial condition, results of operations and business and 
certain of Severn Trent's plans and objectives with respect to these items.
                                                                           
Forward-looking statements are sometimes, but not always, identified by    
their use of a date in the future or such words as "anticipates", "aims",  
"due", "could", "may", "should", "expects", "believes", "intends", "plans",
"targets", "goal" or "estimates". By their very nature forward-looking     
statements are inherently unpredictable, speculative and involve risk and  
uncertainty because they relate to events and depend on circumstances that 
will occur in the future.                                                  
                                                                           
There are a number of factors that could cause actual results and          
developments to differ materially from those expressed or implied by these 
forward-looking statements. These factors include, but are not limited to, 
changes in the economies and markets in which the Group operates; changes  
in the regulatory and competition frameworks in which the Group operates;  
the impact of legal or other proceedings against or which affect the Group;
and changes in interest and exchange rates.                                
                                                                           
All written or verbal forward-looking statements, made in this document or 
made subsequently, which are attributable to Severn Trent or any other     
member of the Group or persons acting on their behalf are expressly        
qualified in their entirety by the factors referred to above. Severn Trent 
does not intend to update these forward-looking statements.
