Living on the outskirts to town, all the houses on our development have septic tanks for black water. The greywater passes through the tank and disperses into a drain. Most 0f our neighbours call up the 'honey bucket' wagon once every month or so to empty their septic tanks. At 500 baht per visit, the cost to empty a septic tank runs around 6,000 baht per year. With judicious management by myself and a dead cat, our septic tank went nearly 5 years without emptying. Unfortunately, a couple of months ago I started hearing the telltale sounds that the tank was full and needed servicing by the 'honey bucket' wagon. I called a passing truck to empty the tank. However, in emptying the tank, all the good bacteria that disposed of and ate the solid matter went too. Fortunately, I remembered the dead cat treatment recommended by a good Aussie friend of mine (
@Rice) and went to HomePro in search of a 'dead cat'. I found this product for less than 300 baht:

I emptied about a third of the tin, about 400 grams, into the WC, flushed the system and watched as it gurgled away and into the septic tank. One week later, I am reasonably confident that the 'dead cat' treatment is working again. The gurgling sounds that indicated the septic tank was full have stopped and the water from the WC flushes away smoothly again. Hopefully, I will not need the 'honey bucket' service for another 5 years of or so. That will be 30,000 baht in my pockets and not theirs.
P.S. Call me a 'cheapie charlie' if you like but why throw away 500 baht a month when you do not need to.
