Situation of the Works.— The Sewage Works are situated
on the South side of the District (in Wood Green
Parish), and within 100 yards of a small brook, into which
the effluent flows. The crignal works were completed at
the end of 1886, from designs furnished by Mr. Baldwin
Latham, M.Inst C.E. and were executed under his direction.
The working of the tanks and original filters has been
altered and improved, and three Primary Contact Beds
have been constructed, under the supervision of Mr. E. J.
Reynolds. Assoc. M.Inst. C. E.
The method of treatment is as follows
The sewage, which enters the works by gravitation, is
first passed through a revolving screen, after which a solution
of Buxton lime equal to 4 grains per gallon is added, and
the whole is thoroughly mixed. It then receives aluminoferric
to the extent of 1 grain per gallon, and is again well
mixed by passing through a salmon ladder; and in this condition
it flows into settling tanks, of which there are five,
four having a capacity of 70,000 gallons, and the fifth,
which will hold 92,000 gallons.
