Singapore water cost 10 times more than Hong Kong!!

That’s what Leong Sze Hian claimed.

But, really?

First, we need to know how domestic consumers are billed for water usage in Hong Kong.

Here’s what we gleaned from Hong Kong’s Water Supplies Department.
1. Domestic consumers are usually billed for their water charges at 4-monthly intervals according to the meter readings taken. 
2. The charges payable are calculated on a tariff structure which consists of 4-tiers with progressively increasing prices.

To help you understand, here’s an example of a bill that is calculated based on this tariff structure.

In this example, you see that the water consumption cost (60 cubic metres) for Mr Chan is HK$238.61 for 4 months.
This means his average monthly consumption (15 cubic metres for each month) for that 4 months is HK$59.65.

This is equivalent to S$10.90.

Here’s Leong Sze Hian’s table of comparison of the cost of monthly water consumption based on 15 cubic metres a month:

How did Leong Sze Hian arrive at such a low cost?

He applied a tariff structure that is meant for billing at 4-monthly interval to calculate monthly usage.
In so doing, he made the erroneous assumption of 12 cubic metres of free water every month instead of every 4 months.
Thus the cost of water reflected in his table ($2.28) is the cost of 3 cubic metres of water.

He assumes that there is 12 cubic metres of free water every month.

Leong Sze Hian assumes that there is 12 cubic metres of free water every month.
Leong Sze Hian has many titles to his name. He also referenced the Hong Kong’s Water Supplies Department as his source of information.

How did he make such an erroneous assumption?

The price of water in Singapore is indeed more expensive than Hong Kong.

But 10 times more expensive? Of course not. That’s being misleading to the extreme.

Puzzle no more. Let this table inform you of the total cost of water in Singapore including taxes, compared to other cities.
