Application of GIS for Mapping Water Systems in Ebonyi State, Nigeria

 

A lack of reliable data on water services and distribution networks in Ebonyi, Nigeria contributes to the challenge of effective management and operations of the state’s water facilities. To help remedy the problem, USAID’s Sustainable Water and Sanitation in Africa (SUWASA) is working in partnership with Ebonyi State Water Corporation (EBSWC) to digitize the utility’s water service and distribution lines.

The process involves the water corporation’s engineers and technicians working with Geographical Information System (GIS) software to map piping and fittings networks. The goal of the collaboration is to guide and train the corporation’s technical staff to continuously enter data into the system. The process allows the staff to note the locations of water network landmarks on the map and to recognize these landmarks in satellite images. The new digital
map and database will provide the corporation with the tools and knowledge to continually map its distribution network.

 

“The knowledge and use of this technology in service distribution and management is very useful for ourplanning as a utility company,” said Success Okoti, an Ebonyi State Water Corporation engineer.


“We are using Android tablets for the mapping and database. These tools can be used to continue the mapping and data entry into the system,” said Emiko Guthe, a GIS specialist. “More importantly, the distribution network is captured into a GIS that makes it possible to see everything at a glance.” SUWASA’s urban water sector reform project in Ebonyi is part of USAID’s commitment to partner with the state government to expand water service delivery and improve institutional structures that will modernize many of EBSWC’s procedures. These improvements include the introduction of a spatiallyreferenced integrated information management system that provides linkages between the corporation’s billing, finance and asset management systems.
