Water Resources

The firm offers service in Dams and Hydropower; Irrigation and Drainage; Water Supply and Sewage; Rivers, Ports and Marine Works; Flood Control; Erosion and Land Reclamation; River Basin Development; and Groundwater.


Enplan Group has extensive experience in typically arid, semi arid and wet areas. In Nigeria, due to the diversity of land forms and practices, the firm has been involved in projects that have stark variations in climate, soil, culture and land tenancy.

The firm had been involved in the detailed design, construction, and supervision of canal and drainage systems for a large variety of soils requiring different supply systems; including precast forms, unlined canals to clay linings, and concrete linings to piped systems. We have also designed various manual and automated control structures, as well as myriad canal networks to suit different requirements, in order to facilitate efficient distribution and management of irrigation water.

At Enplan Group, Irrigation and Drainage is viewed as a multi- disciplinary project. Consequently, Enplan Group has integrated Community Awareness and Community Participation into our irrigation and drainage projects. It is our belief that sustainable development can only be attained when the communities are involved. Most projects we have carried out using this approach have been successful.


At Enplan Group River Basin Development is treated in a holistic manner, which involves Integrated Water Resources Management (IWRM). Development projects usually cover varied fields including irrigation, agriculture, hydrology, socio-economy, water resources, rural development, infrastructure, road & transportation, dams, water supply, agronomy, soils, livestock, fisheries, forestry and post-harvest.


The firm provides a comprehensive consultancy service in all aspects of water supply both for the urban and rural sectors. Enplan Group has expertise in sanitation and public health engineering including the distribution of potable water for both urban and rural communities. The firm also has expertise in institutional development, economic, optimization and management studies of water supply systems.


Enplan Group has been involved in the investigation, survey, planning and engineering designs of a number of water supply and sewerage schemes. The scope of work carried out include:

  • Water resources investigation and development;
  • Population: studies and demand forecasting;
  • Engineering and geotechnical surveys;
  • Engineering design of Intake works, Treatment works, Transmission and Distribution systems, Storage works and Pumping stations;
  • Planning and design of sewerage schemes;
  • Studies of existing system on operation and maintenance;
  • Financial, administrative, legal and training aspects


The firm’s experience in agricultural development includes irrigated agriculture involving the design of gravity canals, piped irrigation systems (sprinklers, drip etc), and flumes (elevated pre-cast canals) to name a few. Major projects often necessitate the study and improvement of the agricultural practice within a particular project area.

The agricultural investigations usually include detailed studies; surveying and sampling of the ecology and agricultural production; identification of crop varieties, yields, and production rates; analysis of cost of production and income; and proposing methods to improving the agricultural output for the different areas encountered.


The first major dam project undertaken by Enplan Group was the Kiri Dam at Numan, Gongola State (present Adamawa State) for the Savannah Sugar Company. Since then the firm has been responsible for major schemes and a vast number of projects including, the feasibility studies, detailed design and contract documentation, and construction supervision for 38 small earth dams within Katsina State in Nigeria. The firm has also been involved in dam safety appraisals covering major and small dams all over Nigeria, as well as in the alleviation of potential dam failure.

Enplan Group was involved in the redesign of the 3.68 km dam in Jibiya under Jibiya Irrigation cum Water Supply Project for the Federal Government of Nigeria. The dam which was the first of its kind in Africa was redesigned incorporating a geo-dam (which comprises geo-membrane composites) on the upstream slope and geo-textiles material on the downstream to provide protection to the aeolic sand embankment.


The primary objective for Flood Control and Land Reclamation assignments is to identify and study the flood processes within the identified area and to, assess, recommend and design control measures to alleviate the flooding problems. Enplan Group had been involved in major land reclamation and flood alleviation schemes within Nigeria and has gained a wealth of expertise in the design of reclamation works.


The firm’s involvement in water resources projects and studies has made it one of the most experienced consulting firms in Nigeria; particularly in the study and design of hydraulic problems and hydraulic structures respectively.
The firm’s experience in hydraulics includes the design of river control and diversion works; river morphology; urban drainage; coastal and erosion control works; flood alleviation; dams; and weirs and channelisation development.


The firm has a library of computer programs for process hydrological data for water resources development planning. The firms Hydrologists make extensive use of these computer programmes to conduct statistical tests for data reliability, frequency analysis, trend analysis, persistence, risk analysis, synthesis of stream flow, and rainfall and evaporation data analysis. The are also responsible for the planning and modeling of water resources systems, filling in missing data, and recommending analytical and planning techniques, with results expressed in both physical and economic terms.


Enplan Group has been pivotal in advancing groundwater development, introducing modern techniques and practice in the Northern Arid Zone of Nigeria.

The group has been involved in:

  • Interpretation of geophysical surveys;
  • Groundwater development planning;
  • Water sampling;
  • Hydrogeological data collection and mapping;
  • Borehole drilling and washbores development;
  • Litho-logical logging of boreholes.
