Description and recommendations: Manzese is intersected by a number of rivers and streams, along with being intersected by Morogoro road.

As the northern boundary of Manzese is formed by the Ng’ombe river, Chai Bora subward is heavily affected by the river, including the buildings forming Manzese Secondary School. Mvuleni and Uzuri subwards are also affected by the Ng’ombe, as well as being affected by the Mbokomu stream that later joins the Kiboko river, leaving the buildings along its banks at major risk of flooding.

In the central part of the ward, the Mbokomu river also cuts across and impacts Muungano subward. In the southern part, Midizini and Mwembeni subwards house a stream that later connects to the China river in Makurumla.
