UPGRADING OF SURFACE WATER MONITORING STATIONS UNDER THE IGAD-HYCOS PROJECT

The World Meteorological Organization (WMO) has set out to support the upgrading of Hydrometric Networks within the IGAD countries under the Hydrological Cycle Observation System, IGAD-HYCOS Project. This is in line with the objectives of the project which is to: provide adequate infrastructure for hydrological observation and appropriate regional cooperation in information exchange among participating countries; develop strong and sufficient technical and institutional capacity to collect, store and disseminate timely and accurate hydrological information; and to enable the efficient and economic management of national water resources.

In Kenya, the IGAD-HYCOS Project National Focal Point officer sits at the Ministry of Water. The installation of the hydrometric (telemetric) equipment is done by Water Resources Authority (WRA) and supervised by A WRA hydrologist. Fifteen Regular Gauging Stations (RGSs) in Kenya were earmarked for upgrading to telemetry.

Installation of fourteen GPRS telemetric equipment had been completed by December 2016. The equipment installed included water level, temperature/humidity and rainfall sensors which are connected to a Data Collection Platform (DCP).  All the sensors are set to log on hourly basis and automatically push (transmit) data to the File Transfer Protocol (FTP) every three hours. The system transmits data using GPRS communications protocols and can be accessed using the computer, tablet or smartphone via a web-based automatic data collection software application.
