The increase is quite reasonable giving that the rate has not been revised for almost 30 years. Bare in mind IWK collects RM 8 last time irregardless how much shit is disposed from your house, bungalow, semi-Ds, condo all the same flat rate.

Maintenance of all IWK equipment (just like your air filter/water filter) is always on the rise with our people mentality of throwing daipers, sanitary pad, condoms, tissue, cooking oil, solid food watste all into the floor trap and hope it will just disappear somewhere plus the awareness of people appreciating sewerage treatment is very poor in malaysia i would say...

a very simple comparison u can take is how much is the cost u pay changing the car oil filter (just to filter oil) during maintenance versus how much we are paying for the sewerage treatment u will find how cheap it is in malaysia....

speaking from a industry with some relation to sewerage treatment
