This paper examines the introduction of competition into the English and We
lsh water and sewerage industry following privatisation of the 10 regional
water authorities in 1989. It outlines the development of comparative, capi
tal and product market competition, arguing that the greatest opportunities
now lie with the last through the introduction of common carriage agreemen
ts, the extension of Inset appointments and the introduction of transferabl
e abstraction licences. Despite competitive innovations, the industry remai
ns highly regulated, complex and difficult to enter. One of Ofwat's outstan
ding challenges for the next decade is to examine the means by which the re
gulatory burden might be lightened and barriers to entry lowered, to encour
age potential entrants to compete with incumbents.
