building operations in the borough since the schemes were prepared to undertake further works as
(i.) A relief sewer from the junction of Balham High-road and Tooting Bec-road to
the river Graveney ; (ii.) the improvement of certain portions of the waterway of the river
Graveney ; and (iii.) a sewer (the Wandle-valley sewer) with branches, from the Wandle

low lying areas in the valley of the rivers Wandle and Graveney.
A contract amounting to £34,319 has been let for (i.) and (ii.). The preliminary work of making

in hand.
