Iju-Ishaga — The Historic Cradle of Lagos's Water Supply

Overview

Iju-Ishaga is a district of the Ifako-Ijaiye Local Government Area, whose history is inseparable from that of the Iju Waterworks, established in 1910 under its original name, the Federal Water Supply, under colonial federal authority. The facility was officially commissioned in 1915 by Lord Lugard, then Governor-General of the colony of Nigeria, making Iju-Ishaga the historic cradle of modern water supply for the whole of Lagos.

Infrastructure Born of Colonial Public Health Necessity

The Iju plant was originally designed with a capacity of 2.4 million gallons per day, intended primarily to supply drinking water to colonial residents in Ikoyi. The project stemmed from medical recommendations warning of the poor quality of water drawn from surrounding waterways and the wells used by Lagos's population, a major public health concern for the colonial administration of the time.

Decades of Continuous Expansion

The plant's capacity was progressively increased throughout the 20th century: raised to 6 million gallons per day (MGD) in 1943, then 11 MGD in 1954, it reached 35 MGD in 1973 after a further upgrade carried out in 1962, before being raised again to 45 MGD in 1982. It was during this last modernization phase, between 1982 and 1985, that an elevated 5,000-cubic-meter reservoir was built at Ishaga, which became a defining architectural landmark of the district and the origin of the compound name "Iju-Ishaga." When Lagos State was created in 1967, responsibility for water supply was transferred from the federal government to state authorities.

Neighborhood Life Today

Beyond its historic infrastructural role, Iju-Ishaga has developed into a dense, sought-after residential district, benefiting from good connectivity with the rest of the Ifako-Ijaiye Local Government Area. The district continues to draw families seeking a stable living environment, right next to one of the oldest and most strategic pieces of public infrastructure in all of Lagos.

A Living Memory of the City's Technical History

Few districts in Lagos can claim such a direct, continuous link to a founding piece of public infrastructure dating back more than a century. Iju-Ishaga thus embodies a lesser-known side of Lagos's urban history, that of the major colonial-era engineering works that shaped the sanitation and growth of the modern city, long before the demographic explosion that defines today's metropolis.

Administrative context

This neighbourhood is part of the Ifako-Ijaiye LGA, which covers 43 km² and had 427,878 inhabitants at the 2006 census (2022 estimate: 633,200). These figures cover the whole LGA, not the neighbourhood alone, and the 2006 census is disputed. See the Ifako-Ijaiye LGA page and Wikipedia.
