Itahari Sub-Metropolitan is the largest city in Sunsari District located in the Province No.1 of south-eastern Nepal. The total population was 1,40,517 living in 33,794 households extended in the area of 93.78 square kilometres and the population growth rate is 6.23. 

The sub-metropolitan does not have municipal sewer network, thus every household rely on onsite sanitation system. No open defecation is practised, but only 9 % of the faecal sludge is managed safely. Traditional manual scavenging is predominant means of emptying while demand for mechanized emptying is increasing in the core city areas. There does not exist a faecal sludge treatment facility and the sludge from manually emptied containments is dumped in a pit on the land owned by household’s whose containment have been emptied.
