breakthrough in Nigeria by securing water supply schemes from Soba, Saminaka and Zonkwa Dams project in 1974.
NESPAK launched joint ventures with the Associated Consulting Engineers (Pvt.) Limited (ACE) by setting up its subsidiary company, the Engineering and Consultancy Associates Nigeria Limited (ECAN) in 1975, which was co-shared by a Nigerian citizen, Alhaji Muhammad Armya'u. NESPAK, with the active participation of ECAN, handled many consultancy contracts during its 22 years of operations in Nigeria.
After the death of Alhaji Armya'u, various administrative and financial problems emerged, which finally led to the closure of NESPAK's Regional Office in Lagos in 1996.
NESPAK completed a total of 22 projects worth US$ 710 million during 22 years of its business operations in the Federal Republic of Nigeria.
NESPAK's major area of consultancy services in Nigeria had been the water resources development and the road construction.

Elevated tank for Lafia Water Supply Project
Raw water main from headworks totreatment plant for the Lafia WaterSupply Project
This project involved the construction of a modern water supply system for the Saminaka Town and its suburbs in the Kaduna State. The source of water was the River Karami flowing on the western side of the Saminaka Town. An ogee type 340 ft. long weir was built across the river to store water during the low flow periods. Three open shaft split case centrifugal pumps were installed at a dry intake built on the upstream side of the weir to pump raw water to the treatment works. Water from treatment works was then pumped by three centrifugal pumps through a 12" A.C. transmission main to directly feed the Saminaka Town Distribution Network.
Designed for the Lafia Town, the capital city of Nasarawa State, this project was based on surface water from River Amba flowing on the western side of the city. A 5.6m high dam with a storage capacity of 6.0 million cu. m was constructed across the river along with an intake structure near the upstream toe. Raw water was drawn from the reservoir through intake structure and pumped by two 280 H.P. turbine pumps to the treatment works.
Water from treatment works was pumped by three 250 H.P. centrifugal pumps to 22,700. cu. m service reservoir located in the Lafia Town. Low and high level zones were fed from service reservoir and three overhead tanks.

This surface-water-based supply system was aimed at providing drinking water to Zonkwa, Madauci and Zongan Katab Towns in Kaduna State.
The source of water was an earth-fill dam across River Karami flowing on the western side of Zonkwa Town. Reservoir created behind the dam was tapped through an intake structure constructed on the upstream side. Raw water was pumped by three vertical spindle

centrifugal pumps to water works for treatment.
Treated water was then pumped to a 0.5 MG tank constructed over a tower at Madauci and balance supply to Zonkwa fed directly from the transmission line through the A.C. pipe network. Water for the Zongan Katab System, located 15 miles from Zonkwa, was gravitated from Madauci Tank through the break pressure tank.
This project comprised the construction of a weir (Phase-I) and a dam (Phase-II) across River Gokwoli, water treatment works, transmission mains and distribution system for Potiskum and Damagum Towns and nearby villages.
Raw water was drawn from weir and dam reservoirs through wet type intake structures and pumped by turbine pumps through 400 mm dia, 6.13 km long transmission main from the weir and 450 mm dia & 14.62 km long Ductile Iron (DI) main from the dam to a modern treatment plant at the Damagum Town.
Water from treatment works was pumped by four centrifugal pumps through 300 mm (Phase-I) and 450 mm dia (Phase-II) 30 km long D.I. mains to the service reservoir in Potiskum Town and through a third main to an elevated tank in the Damagum town.

Located in Biu Town in the Southern Borno State, this project comprised an 18m high earth-fill dam with a crest length of 300 m and 11.1 million cu. m reservoir across River Duvana. Raw water from the reservoir was pumped by two centrifugal pumps each installed at the intake structure near the upstream top of dam through 450 mm dia, 4.74 km long Ductile Iron (DI) transmission main to a modern treatment plant.
Water from treatment works was pumped by two centrifugal pumps to a service reservoir. Water was then boosted to two overhead tanks in the low-level and high-level areas in Biu Town.
The purpose of this project was to supply potable water to Sokoto, the capital of the arid Sokoto State. The project involved the construction of a weir, raw water intake structure, 110,000 cu. m/day water treatment plant, five ultramodern computerised pumping/booster stations, five standby 3 MW power houses, six welded steel elevated/ground reservoirs of capacity up to 7000 cu. m and 80 km long transmission and distribution pipelines of sizes varying from 200 mm to 1100 mm.
The water treatment plant components included equipment for aeration, flocculation, rapid gravity filtration, chemical dosing chlorination and wastewater recycling.

This project was aimed at the development of 39,000 hectares of land along the left bank of the Tomas River. The proposed gravity system included 22.5 km long main canal supplying water directly to 14 distributaries. Three night storage reservoirs fed from the main canal and supplying water to three branch canals with a total length of 12 km were designed. A distribution network having a total length of 22 km distributaries with all associated structures were also designed for the Tomas Irrigation Project.
NESPAK rendered services through ECAN for the Ikara Dam which was an essential part of the Ikara Water Supply Scheme.
The project is located in the Savanna Region of Northern Nigeria which lies about 48 km east of the main road from the Kaduna Sate to the Kano State. The dam lies in a broad shallow valley with relief variation from elevation 99 m in river valley to about elevation 118 m in the highest area.
The dam involved the construction of 1,800 m long, 16 m high earth-fill embankment and a spillway forming a reservoir up to about 2,500 m upstream. The main flow section of the river is about 7 to 12 m broad with about 2 m high banks.

This project involved the construction of a dam across Rima River in the Sokoto State for the purpose of flood regulation, irrigation and water supply.
The Goronyo Dam is a sand-fill structure with a height of 21 m and a total length of 12.5 km. It has a storage capacity of 976 million cu. m. The dam consists of three homogenous sections i.e. the main and secondary dams and saddle dyke. A
2200 km reservoir was created due to the

construction of the dam. The reservoir provided an annual regulated flow of
3425 million m to double the rice cultivated riverine areas from 40,000 ha. to 80,000 ha.
Two residential complexes namely Keta Senior Residential Complex and the New Rimawaj junior residential units were also built in the surrounding areas of the dam.

The detailed design of the Mubi-Bazza Highway was awarded to NESPAK through an international competition in 1979. NESPAK also provided construction supervision services for the project through a separate contract in 1987.
For the design purpose, aerial photography of different routes was carried out, providing the basis for the selection of the alignment which was transferred on to the ground for detailed

surveys. Investigations pertaining to water availability, soils, materials and hydrology were also carried out.
The geometric design was then undertaken, employing international standards and computations pertaining to curvature, grades, cross-sections, quantities and estimates were carried out using computer. Pavement and structural designs were executed through sophisticated methodology.
