From its inception, Enplan Group has been associated with water resources development all over the country.

The firm had been involved in the detailed design and construction supervision of canal and drainage systems for a large variety of soils requiring different supply systems from unlined canals through clay linings, concrete linings to piped systems and precast forms. Also various manual and automated control structures or canal network have been designed to suit different requirements in order to facilitate efficient distribution and management 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.

Enplan Group has been involved in River Basin Developments since its inception. River Basin Development has been treated in a holistic way and involved Integrated Water Resources Management (IWRM). Development projects usually cover many 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 including storage, transportation and marketing.

The firm provides a comprehensive consultancy service in all aspects of water supply both for the urban and rural sectors. The firm has gained experience and developed expertise in sanitation and public health engineering including the distribution of potable water both for urban and rural communities, institutional development, economic, optimization and management studies of water supply systems. The Firm has been involved in the investigation, survey, planning and engineering designs of a number of water supply and sewerage schemes. The scope of works carried out have Included:

◊ 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 has included irrigated agriculture involving the design of gravity canals, piped irrigation systems (sprinklers, drip etc) and flumes (elevated pre-cast canals), etc. Major projects have often necessitated the study and improvement of the agricultural practice within a particular project area.

The agricultural investigations have included detailed studies, survey and sampling of the ecology, agricultural production, identification of crop varieties, yields, production rates, cost of production and income and proposing methods of improving the agricultural output for the different areas encountered.

The firm has been involved in dam projects since 1970. The first major dam project undertaken by Enplan Group is the Kiri Dam at Numan, Gongola State for the Savannah Sugar Company. The firm had been responsible for major schemes and a vast number of projects involving all kinds of dams. Typical of the firm’s experience is the feasibility studies, detailed design, and contract documentation and construction supervision for 38 small earth dams within Katsina State in Nigeria.

Enplan Group was involved in the redesign of the 3.68 km dam at 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 firm has also been involved in dam safety appraisals covering major and small dams all over Nigeria, also in the alleviation of potential dam failure.

The primary objectives for these kind of assignments are to identify and study the flood Processes, within the identified area, and to, assess, recommend and design control measures to alleviate the flooding problems. The firm had been involved in major land reclamation and flood alleviation schemes within Nigeria and has gained a lot 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, weirs and channelisation development.

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

Enplan Group has been involved in many groundwater development projects. The Firm has helped in advancing groundwater development, modern techniques and practice especially in the Northern Arid Zone of Nigeria.

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