🇰🇪 Ruiru is a municipality and sub-county in Kiambu County, Kenya. It sits within the greater Nairobi Metropolitan region. According to the 2019 national population census, Ruiru is the 4th largest urban centre in Kenya by population. The name Ruiru is of the Kikuyu dialect and possibly relates to the black cotton soil that is found in most parts of Ruiru to the east and south.

The geographical co-ordinates of Ruiru are: 1°10'04.0"S, 36°58'24.0"E (Latitude: −1.167778; Longitude: 36.973333).

History This area was a sisal and coffee growing district with sisal on either side of the river to the right of the main road to Thika. It is now a housing area. There used to be four main manager houses on the estate on the south side of the river. The area was given over to an African consortium to be developed into smallholdings in the 1970s.

Prior to Kenya's independence, Ruiru was administered under the Nairobi City Council and was referred to as the Western Rural District. After independence, the area was put under the administration of the Kiambu County Council before being elevated to a town council in 1986. In 1997, Ruiru was upgraded to municipality status comprising nine elective wards: Biashara, Gitothua, Gatongora, Kahawa Sukari, Githurai, Kimbo, Jacaranda, Theta, Viwanda, and Murera.

The creation of the Nairobi Metropolitan Region (NMR) by an Executive Order in May 2008 put the town under its wider urban integrated plan.

Neighbourhoods The expansive Ruiru municipality sprawl comprises many neighbourhoods including Ruiru Town, Tatu City, Kahawa, Githurai 45, Mwihoko, Membley, Kamakis, Varsity Ville, and Northlands City.

Economy Ruiru is an industrial town with several major factories, including Devki Steel Mills, Super Foam Limited, Spinners & Spinners garment factory, Ruiru Mabati factory and Ruiru Feeds Limited.

The Tatu City Industrial Park is found within Ruiru and is home to tens of factories, including BIDCO, Copia, Dormans, Davis & Shirtliff, Tianlong, Stecol and Dr. Mattress.

The town is served by banks and shopping malls. It has seen a housing boom, with many coffee estates being converted into residential areas, including an upcoming multi-billion Tatu Estate. Information and communication technology businesses are also emerging, including SmartEdge PASHA Center, a digital village where the community can buy computers and find free computer training.

Several banks have opened their branches in Ruiru, particularly in the Kamakis area, including NCBA, Sidian Bank, Diamond Trust Bank, Equity Bank and Co-operative Bank.

Infrastructure projects Ruiru is home to major government and private infrastructure developments, including Tatu City, a 5,000 acre mixed-use project. The proposed Northlands City project is also found in this area.

Prominent government-led infrastructure projects in Ruiru include the Ruiru Sewer Plant, the dualling of the Nairobi Eastern Bypass Highway, and the Nairobi commuter rail service project.

Population Ruiru is the fourth largest urban centre in Kenya by population. The rapid population growth is attributable to several factors: the shortage of affordable residential housing in Nairobi; the infrastructure development, especially Thika Road and Nairobi Eastern Bypass Highway, and the associated commercial and residential development that followed the new highways; and the presence of university campuses in or near Ruiru.

Education Two universities have their main campuses in Ruiru, namely Zetech University and Kiriri Women's University of Science and Technology. The Kenyatta University (Main and Ruiru Campuses) are also found within the vicinity of the municipality. The University of Nairobi and other institutions of higher education have campuses in or near Ruiru. Danjose Academy, one of the leading academic Primary Institutions, is found in Ruiru. In July 2022, the President of Kenya, Uhuru Kenyatta, broke ground in Ruiru for the Amref International University. The Health Science university will be hosted within the expansive Northlands City land found in the southern wing of the municipality.

Politics Ruiru was originally part of the greater Juja Constituency until it was hived off and made into an independent electoral area. It is separated from Juja by the Ruiru river as it flows downstream to the confluence with the Nairobi River.
