As your Council are aware, the complaints of the condition of the Lower
District of the Old Lee and its Tributaries have been constant for many years

Special Drainage District, and remove the nuisances complained of from the
Lea.

Mills Pumping Station ; cr, as an alternative to an entirely new outfall
to be constructed east of the river Boding and South of Ilford "
(Scheme B). This latter scheme "imposes on the Authorities the
duty of treatment and disposal of the sewage at the outfall." The
Engineers describe the method of treatment and disposal of the
sewage at the outfall in the following terms :—" It is proposed to
acquire an area of 120 acres, as shewn on the plan, for the purpose
of carrying out the work of purifying the sewage. It is proposed to
construct open subsidence tanks of sufficient capacity to contain the
daily dry weather flow from a population equal to one half of the
ultimate population. The sludge obtained from the subsidence in
