23. The proposed sites are as follows:-
No. 1 Tank.-Situated in Garden Road near the Volunteer Headquarters. Constructed in 1903 and has been working since the beginning of 1904.
No. 2 Tank. Proposed to be constructed over the nullah at the junction of Water Street and Battery Road. It will flush the Low Level sewers in Des Voeux Road West, west of French Street.
No. 3 Tank. It is proposed to make some slight alterations to the existing Cowper's Tank at the junction of Centre Street and Bon- ham Road, and though the distance from the Low Level sewers is great, the approach gradients are steep. The outflow from this Tank must be carefully regulated or the manhole covers may be burst open, and the house connections in the Lower Levels flooded by the backing up of the water in the sewers with slacker gradients. This Tank will flush the Low Level sewers in Des Voeux Road West and Queen's Road West.
No. 4 Tank.-Proposed to be constructed in the Blake Gardens adjoining Station Street, and will flush the Low Level sewers in Wing Lok Street, Morrison Street, Connaught Road West, Bonham Strand West, Hillier Street, &c.
No. 5 Tank.-Proposed to be constructed either at the junction of Holly- wood Road and Pottinger Street or on the triangular piece at the junction of Wyndham Street and Arbuthnot Road, and will flush the Low Level sewers in Queen's Road Central and Des Voeux Road Central.
No. 6 Tank.-Proposed to be constructed at the top of Stone Nullah Lane and will flush the Low Level sewers in Queen's Road East, Ship Street, Wanchai Road and Praya East, &c.
24. The proposed Tanks will flush those Low Level sewers that are at present most liable to silting. It may be necessary to make additions to this list in the future especially if the Praya East reclamation scheme is carried out.
25. An estimate of the probable cost of each Tank is given in the attached list, (Appendix B.) the total of which amounts to $10,670 excluding No. 1 Tank which
is built.
26. I have not made any estimates of the cost of re-laying any of the lengths of sewers mentioned in this report, nor any alterations to inverted syphons, &c.
27. The details of the Tanks have not been worked out until the suggested sites have met with your approval.
