The state urban water scheme provides water for Aba and Umuahia. The larger LGA headquarters are also expected to benefit from this scheme. For rural areas, there is a rural water scheme. However, most rural dwellers rely on streams and wells for their domestic water needs.
Communities living in the coastal plain sand areas experience acute water shortage between November and March when wells and water ponds dry up.

In the area of Water Supply, the state is engaged in the constant maintenance of existing water works while also opening up new Regional Water Schemes in various communities in Abia State.

i. Umuahia Regional Water Scheme
