The Hydrogeology Department is charged with the responsibility for assessment of the status of the groundwater resources both quantitatively and qualitatively within the sedimentary and basement areas of the country. In addition, the Department monitors groundwater fluctuations and carries out investigations in the coastal areas in order to device management tools to check saline water intrusion.

This Department undertakes project-specific groundwater investigations for the purpose of establishing the trend of critical parameters needed for solving specific groundwater problems; hence the use of remote sensing, geophysics and isotope techniques.

The Department is responsible for assessment of surface water resources through collection of data on river discharge and sediment transport from the hydrological network of stations. In addition, the department is also responsible for data retrieval and processing.

This Department is responsible for the design, installation and maintenance of hydrological stations.

It is also responsible for operation and monitoring of the agency’s satellite and telemetric  gauging stations through which it provides information for flood forecasting.

This Department is charged with the responsibility for data management and information dissemination to users of Hydrological products. It therefore harnesses, processes and archives hydrological data. It is also responsible for publication of hydrological yearbooks, bulletins and scientific reports. The Department is also charged with the responsibility for monitoring of the impact of climatic change on water resources and inter-agency support services and bilateral relations.

LEGAL UNIT
The Legal Unit is a very important arm of the Agency. Its functions are contained in the back up law of the Agency. The primary duty of the Legal Unit is to ensure that the Agency operates effectively within the confines of the law that established it. Section 10(2)(b) provides that the Legal Adviser shall Hydroinfoister and discharge all legal obligations of the Agency. The functions are three fold:
1. Advisory
2. Contractual
3. Litigation
The Legal Unit interprets the Law establishing the Agency and other necessary Laws like Public Procurement Act and other laws establishing sister agencies in other to establish areas of peculiarities. Section 7 of the relevant law creates the functions of the Agency. It is the duty of the Legal Unit to interpret all these functions for ease of application. Section 10 of the Law creates the office of the Legal Adviser of the Agency who is also secretary of the Board.
The Legal Unit will also be actively involved in drafting contracts on behalf of the Agency and in executing such contracts. The Legal Unit will ensure that the Agency is not trapped by any contractual clause and guards against unnecessary litigation. The Unit represents the Agency in Court matters. The Legal Adviser will also perform such other functions as the Board or the Director General may from time to time assign to her.

NIHSA_Unit_Press icon

PRESS UNIT
The press unit is charged with the responsibility of image making of the Agency. It has responsibility to liaise with media houses on the activities of the Agency. This is done by publicizing these activities in the media. It creates a brand image for the organization that will be unique and consistent with its vision and mission. It also creates an environment of friendliness that encourages more stakeholders participation in the activities of the agency by creating a unique identity for both individual and corporate members of our public.

It ensures that there is an efficient and effective government accounting system in the Agency and that timely and accurate financial statement is provided to the Office of the Accountant General by the Agency. It operates under the Hydroinfoistration and Finance Department.

NIHSA_Unit_Audit icon
AUDIT UNIT

This Unit is the instrument through which the internal Audit mechanism is effected in the Agency. It serves to ensure that management internal control system is function and strictly adhered to. It also maintains the financial inflow and outflow within the Agency and that there is check and balance in financial decisions.

NIHSA_Unit_Procurement icon
PROCUREMENT UNIT
Sequel to the approval of the Federal Executive Council (FEC) in 2007 for the transformation of the defunct Department of Hydrology and Hydrogeology to the Nigeria Hydrological Services Agency (NIHSA) under the headship of Mr. John Chabo, the Procurement Unit of the Agency (NIHSA) was constituted in July, 2007. The Unit was to handle all procurement matters of the newly created Agency.

Organizational Structure


NIHSA_organizational Structure_banner

The Federal Ministry of Water Resources is the umbrella government organ under which all water resources activities at the Federal level, including hydrological activities, operate.
The Federal Ministry of Water Resources is the umbrella government organ under which all water resources activities at the Federal level, including hydrological activities, operate.
Consequently, the Honourable Minister of Water Resources sits at the top of the organizational framework of the Nigeria Hydrological Services Agency as the apex authority from whom all other responsibilities emanate by statute.
There is a Governing Board under the Honourable Minister below which are the Director-General and Management, who see to the day-to-day running of the Agency.

There are six (6) Departments in the Agency, five (5) technical Departments and one (1) Department for general services. Each of the Departments operates under the leadership of a Director and the Departments are further sub-divided into Divisions and Units for effective discharge of their responsibilities. There are various Units such as Legal, Audit, Procurement, etc that function directly under the office of the Director-General.

The organizational structure of the Agency, beginning from the Office of the Honourable Minister are as shown in the Organogram in this publication.

Who we are


The Nigeria Hydrological services agency (NIHSA) is a governmental agency established under the ministry of water resources. The Act for the establishment of the Nigeria Hydrological Services Agency was signed into law by President Umaru Musa Yar’adua on the 27th day of August, 2010

What we do


Like any typical Hydrological Service operating in line with the WMO guidelines, and in accordance with international best practice, the Nigeria Hydrological Services Agency’s primary function is to provide data/information on the location of water resources in time and space, their extent, dependability, quality and the possibilities of their utilization and control on a continuous basis.
Such information is provided through the following activities:
1. Assessment of Water Resources: This involves ascertaining the quantity, quality, distribution and developmental potentials of water resources and also the ability of the resources to meet immediate and future demands.
2. Providing information for planning, design and operation of water projects and other facilities or non-water projects consuming water.
3. Monitoring the impact of non-water sector activities on water resources.
4. Providing security for life and property against water related hazards such as floods and drought, through forecasting and related activities.
5. Providing information and management of trans-boundary water bodies.

The Nigeria Hydrological Services Agency (NIHSA) operates and maintains hydrological stations nation-wide for gauging of surface water points. In addition, it undertakes groundwater exploration and monitoring. The data collected is stored in robust database system, analyzed and processed for the purpose of mapping all the nation’s water deposits and also to provide the vital hydrological and hydrogeological data required for sustainable water resources budgeting for various purposes such as domestic, irrigation/agricultural development (for food security and poverty alleviation), hydroelectricity generation, industrialization, tourism and recreation among others.

HISTORY


Hydrological activities in Nigeria date back to 1914 when the Inland Waterways Department, now National Inland Waterways Authority (NIWA) started the establishment of hydrological stations on Rivers Niger and Benue. Later on, other agencies such as various Ministries of Agriculture of the former regions started collecting their own hydrological data. The Regional Government of the then Northern Nigeria started collecting data in Sokoto, Kebbi, Zamfara and Katsina axis with high degree of effectiveness up to 1960′s.
