THE SCOTTISH National Party endeavoured to put a new slant on the

arguments about possible privatisation of Scotland's water supplies

yesterday by demanding that the publicly-owned Scottish industry should

receive the same financial treatment as the privatised one in England

and Wales.

SNP leader Alex Salmond claimed the Scots had subsidised the 1989

privatisation south of the border to the tune of #700m. Scottish local

authorities were entitled to receive the same level of investment, he

said.

''Scottish water needs investment not privatisation,'' Mr Salmond told

a news conference in Edinburgh. ''Privatisation is nothing more than an

ideological red herring.

''To meet EC directives on water and sewerage Scottish water

authorities will require investment of up to #5 billion in the next few

years. All privatisation would do is siphon off profits to the City of

London and the spiralling salaries of a few top executives.''

Scotland's water authorities were already crippled by a massive

capital debt -- #1.1 billion in March 1991 -- and loan charges on this

debt were #193m in 1990-91, he said. Since capital spending in the same

year was just #152m, Scottish authorities had to pay more in loan

repayments than they could spend on essential investment.

By following the SNP's policy much of the initial investment required

in Scotland could be found without massive increases in water charges,

the SNP leader added.

Meanwhile, the Scottish Liberal Democrats, who are also strongly

opposed to any Government moves to take water out of council control,

concentrated their fire on the threatened loss of local accountability.

SLD leader Jim Wallace warned that there was a danger that decisions

about water quality, in particular fluoridation, would be determined on

the basis of profit motive for shareholders rather than concern for the

consumer.

''At present, disconnections from domestic supplies are virtually

unknown in Scotland. However, Scottish Office Ministers have been

remarkably unforthcoming about how under privatisation similar

protection can be given,'' said Mr Wallace.

Ministers scolded Opposition parties for voicing concern but they were

doing little to enlighten the public debate and ease the public's mind.
