    Background: The battle to free the River Thames from pollution is being fought and won. The tidal Thames, upon which London stands, which was once little more than an open sewer, has been turned into one of the cleanest capital city rivers in the world.

    Since Roman times it has been a dumping place. An by 1850's the smell of the river at Westminster was so bad that Parliament was unable to meet -- and thousands died of cholera outbreaks.

    But now the tidal Thames is clean enough for fish to return to every section -- including those where 15 years ago only eels could survive. This year 64 species of fish have been identified in what used to be "dead" stretches of the river.

    Phenomenal numbers of wading birds, who turned their backs on the tidal Thames many years ago, are now coming from Northern Europe again to winter in the centre of London.

    And moorhen and coot are seen by the Tower of London.

    The Port of London Authority is so confident that its big clean up drive is working that it has offered GBP 500 sterling (1,300 US dollars) for the first three salmon to be caught. The prize has not been claimed yet, but any day now the Thames could become a salmon river again.

    The tidal Thames was badly polluted in the years after the Second World War. The cost of post war housing left little over for improving sewage plants. Things were made worse by synthetic detergents.

    Decomposing organic matter took all the oxygen out of the water and fish could not live.

    Between London and the docks at Tilbury the river was little more than an open sewer.

    But in the last eighteen years, GBP 45 million sterling (117 million U.S. dollars) has been spent by the Greater London Council on combating the pollution. Ten large sewage treatment plants have replaced 190 smaller ones that existed in 1935.

    SYNOPSIS: In the Thames in London a long battle against pollution is being fought and won. What was once an open sewer is now one of the world's cleanest capital city rivers. Just over a hundred years ago, Parliament was unable to sit, because of the terrible smell of the Thames -- and outbreaks of cholera killed thousands of Londoners.

    In fifteen years the Port of London Authority, which is responsible for pollution control, has transformed the waters of the tidal Thames. Recently sea trout have been caught and wading birds have returned to the river bank.

    The Thames has been a dumping place since Roman time. It is a busy commercial river with industry lining its banks and it will probably never be beautifully clean again. But now at all times in all sections of the river there is the oxygen essential to fish life.

    Some of the river's biggest tributaries are effluent outfalls.

    By 1975 all London's sewage will be biologically treated.

    Discharges from factories are strictly controlled and where-ever possible are diverted for special treatment by local authorities.

    Every day Port of London Authority officials take samples of the water. They also study the causes of pollution. In the last eighteen years the Greater London Council has spent forty-five million pounds improving sewage plants. And a further forty million pounds will have to be spent by 1980.

    SYNOPSIS: The aim is to have at least ten per cent of the maximum possible dissolved oxygen in the water. That would make the Thames a completely healthy river.

    Specially adapted dredgers tackle the floating driftwood and debris. For the tidal sections of the Thames are almost a closed system. Because of the ties it can take floating rubbish three months to get to the open sea.

    When oil spillages occur, chemicals are hosed over them to disperse the pollutant.

    Mechanical aerators are used to try to force as much oxygen into the water as possible. For decomposing organic matter takes oxygen out of the water.

    There are sans and ducks in plenty and by the Tower of London there are even coot and moorhen to be seen.

    The tidal Thames will probably never be as clean as this section, a little higher up stream at Kingston.

    But great progress has been made. The Port of London Authority have offered five hundred pounds for the first three salmon caught. The Thames could become a salmon river again after generations of pollution.
