with that of the neighbouring district of Southgate, is ied to th6
Council's sewage farm of 235 acres, where it is treated by broad
irrigation. The effluent enters Salmon's Brook near Angel Road,
and reaches the river below Tottenham Lock, two miles further
down and well below the intake of any water supply.
The Council have recently brought into use a considerable area
of land, known as Clavering's Farm, that was not previously
available for sewage treatment, and in this way it is hoped that
longer intervals of rest being secured in future for the different
irrigation areas, a less variable and better effluent will be obtained.
An attempt has been made to reduce the amount of the suspended
solids in the sewage and so render it more suitable for putting on
the land, by improvising in the large underground receiving
reservoir a form of " septic tank " treatment. Owing, however, to
the heading up of the sewage in the sewers which this involved,
and the consequent escape of offensive gases, the attempt at
septic tank treatment was not continued.
In consequence of the growth of our population and that of
Southgate, the contributing district, which now sends more than the
amount of sewage authorised under the award of 1883, it is
recognised by the Council that some supplementary scheme will
have to be introduced to provide in future for the increasing amount
of sewage to be dealt with.
In 1903 the Engineer reported to a Joint Committee representing
the Districts of Cheshunt, Edmonton, Enfield and Southgate on a
scheme embracing all these districts, but the negotiations finally fell
through. A Special Committee, the Sewage Disposal Committee,
has now been appointed to negotiate with Southgate and to further
enquire into the general question of sewage disposal. The Engineer,
under their instructions, is at present considering the best means for
increasing the capacity of the existing works, and the Council have
arranged to provide apparatus for water and sewage analysis in the
laboratory at the Town Hall, to enable me to make regular
