Past Performance

Project Name:

Central Ogbia Water Supply Facility

Location: Bayelsa State, Ogbia City, Nigeria

Services: Designed and managed by JHS Group

Client: Nigeria Federal Ministry of Water Resources

Ogbia is a Local Government Area of Bayelsa State in the Niger Delta region of Nigeria. Its headquarters is in the town of Ogbia in the south of the area at 4°39′00″N 6°16′00″E.

It has an area of 695 km² and a population of 179,926. It is well known for its value to the today's Nigerian state economy mainstay i.e, its oil industry, inasmuch as the local government area encompasses Oloibiri the first place oil was discovered in Nigeria on 15 January 1956.

The existing facility was built in the 1960’s and had been failing to provide clean drinkable water to the city for 10 years, as the city has been expanding rapidly and was in need for a new facility.

Project Size: $134,000,000 USD

Worked with local engineering and contracting firm to elevate and involve local business

Customized the system to the harsh environmental situation including flood season

Used local material and utilized ground uniqueness individuality in providing and creating a bespoke grid base filtration system

Combined different sources of renewal and traditional energy to combat power grid issues

Providing WWO quality water (United Nations water quality)

Project Name:

Lagos Urban Water Planning

Location: Lagos, Nigeria

Services: Designed and managed by JHS Group

Client: City of Lagos, Nigeria

Lagos city is the economic capital of Nigeria with the country's highest population density at 4,193 people per square kilometer. A combination of official neglect, corruption, extreme poverty coupled with rapid, largely uncontrolled, population growth has led to the decay of Lagos’ existing city infrastructure, which determines how livable a city is. Specifically, the human waste (sewage), water and sanitation systems were largely inadequate.

The infrastructure was poorly designed and ignored. It was common to see drinking water pipes pass through open drainage systems. At times, these systems received human waste as a result of locals opening their septic tanks into them or the tanks leaking. The city did not treat all the human waste generated by millions of individuals every day. This waste was emptied directly into the Lagos lagoon with the urban poor being affected the most. Because the drinkable water infrastructure was so poor, many Lagosian depend on sachet water, local water vendors, private boreholes or expensive water filtration units for their the daily domestic and sanitation needs.

Project Size: $240,000,000 USD

(In multiple stages from 2015-2022)

Paid by the City of Lagos

Our goal for this project was to provide unique solutions into the existing system with the existing septic system spread out between 59 different facilities. Every interruption with those facilities would create a catastrophic humanitarian and environmental disaster.

The combination of companies working on this project (local and international) is over 15 and the coordination was done in conjunction with Veolia Water. The focus of the work was to redesign and reconstruct the septic tank system of Lagos Ikoyi (Ikoyi is the most affluent neighborhood of Lagos, located in Eti-Osa Local Government Area).

The area that makes up Ikoyi was originally a continuous land mass with Lagos Island, until it was separated from by a narrow waterway that was dug by the British colonial government. This canal has now been built over or filled so that the island is fused with Lagos Island once again. It has been called the Beverly Hills of Africa or the Belgravia of Lagos.

The design and some of the work was done by JHS and Israeli based Nairda while the balance was performed by Veolia Water.
