The results of the probit model revealed that households age, distance from septic tank, amount of waste
water generated and employment negatively and significantly affect the willingness to pay of households
while household income level, frequency of waste water disposal and easy access to truck positively and
significantly affect the willingness to pay of households for improved liquid waste management. The
estimated monthly mean willingness to pay of the household for the improved liquid waste management is
38.00 birr per month and the total willingness to pay (revenue)of the households in the study area is
found to be 32110 birr per month. That means the annual willingness to pay per household is 456 birr
while the total annual WTP of households in the study area is 385320 birr.
Therefore, based on the key outputs of the present study, there is greater demand for improved liquid
waste management practice in the study area and thus government has to work its best in improving the
services and then collect the money from the households at least for cost recovery which is very important
in a city where there is greater budget deficit.
