In Singapore all consumers must keep a credit balance on deposit with the Muni- cipality and this method is also operated in Shanghai but only for small supplies.
In Bangkok, Colombo, Manila and Saigon no deposit is required.
Waste detection and prevention in all cases more or less follow the orthodox practice of Deacon Waste Water Meters and periodic inspection of plant by Inspectors. General Meterage is mentioned as being considered one of the greatest waste prevention devices.
On the whole the information received while interesting has added little to the data already available and of the systems outlined that of Singapore would appear to be the nearest to our requirements.
With the exception of Bangkok and Saigon all the above cities appear to split up supplies into too many categories though local conditions may make this necessary. In the case of Hong Kong this would not appear necessary or desirable and it would be bet- ter in my opinion to group supplies under as few headings as possible.

Collection of Revenue. All supplies are metered and the consumption shown by such meter is registered monthly as regularly as possible, or quarterly in the case of small consumers.
Payment of accounts is required within 15 days of receipt of application for payment.
In case the consumption cannot be ascertained owing to the meter being out of order or for any other cause, it is calculated according to the consumption of the preceding month.
In cases of delay in payment either for water consumed or repairs, the water supply is cut off without the rights of prosecution being waived thereby.
Waste Detection and Prevention.
Inspections of mains, fountains and hydrants etc. is carried out daily. It is proposed to instal waste detection meters in the near future.
