DRAINAGE.
The main drainage of the Borough links up with the undertaking
of the West Kent Main Sewerage Board, whose purification
works are at Dartford.
The Borough Engineer reports that 586 yards of 9 in.
diameter soil sewer, and 586 yards of 30 in. diameter storm
water sewer were laid to connect the Coppice Estate to the main
sewer and main water course respectively at Princes Plain.
