This river touches many villages like Kotiya, Pandul, Ojha Ganj etc. The people of nearby villages use the bank of Manorama river for last rituals(cremation). The widely popular Manorama Festival, also known as Manorama Mahotsav, has its name after the name of the river Manorama. Manorama festival is organized every year during winter in Tehsil HARRAIYA.

So it was then named as 'Hari-Rahiya' in the regional Awadhi language. Later the name 'Hari-Rahiya' turned into 'Harraiya'.
