The relevant comparison to make is between the price of water from an MWSS connection and MWSS water delivered by vending. That difference is about 13 times.While MWSS water picked up from the other households is the more common mode of buying water among poorer households, the average price per cubic meter does not include the cost of time and effort to queue and carry the water from the source to the household, as well as the inconvenience of not having tap water. Even assuming a lower opportunity cost of labor among the poorer households, total cost of such vended water when those factors are considered may easily reach from P45 to P55 per cubic meter or 8 - 10 times more than the cost of water from an MWSS connection.
