WESTERN POWER Distribution this week emerged as the victor in the battle for control of water utility Hyder, raising questions about the future of its civil engineering staff.
WPD plans to franchise management of Hyder's water assets to its subsidiary United Utilities, which owns neighbouring water utility North West Water.
Eventually, the company expects to put management of its infrastructure out to competitive tender.
Hyder's Welsh Water division is likely to fall into WPD's ownership in less than three weeks, if the offer gains acceptance from all shareholders by 6 September.
WPD said it would not comment on how the changes would affect Hyder staff until after the shareholder vote.
However, a Hyder spokesman said: 'You can't take Welsh Water out of Wales, so that offers a certain degree of stability.'
Last week, neighbouring water utility Severn Trent threatened to challenge the WPD bid in the courts, because it has no short term plans to put management of Hyder's assets out to competitive tender.
An Ofwat spokesman doubted whether such a challenge would succeed as WPD has long term plans to put infrastructure management out to competitive tender.
'We are confident that within seven years any arrangements of this type will be out for competitive tendering, ' he said.
