Ndumberi Coffee Growers Cooperative Society is situated in Kiambu County, an area which forms part of the rich agricultural areas of Central Province, Kenya and on the slopes of the Aberdares mountains. The society headquarters is located about 35 minutes drive north west of the Kenyan capital, Nairobi.
The society is currently composed of three wet mills: Ndumberi, Ngaita and Riabai and was opened by the first Kenyan prime minister then, who later became the founding father of the Kenyan nation Mzee Jomo Kenyatta on 30th June 1962. At the time the society had only one factory with 432 members. Today the society serves a membership of close to three thousand whose benefit extends to over 10,000 families. The average number of coffee trees per farmer is about 200 (0.15 ha). Farmers are also involved in horticulture farming with a ready market in Nairobi city. The fast growing population of Nairobi Metropolis City offers yet another great opportunity for diversification into horticulture by Ndumberi. The fertile red soil, ample rainfall and good tropical temperatures provide a great potential for high production of quality coffee.
The society was Utz Certified in September 2006 and Fairtrade Certified in 2008 and has maintained the certificates to date. With this dual certification, the society now has better market access and members have enjoyed better coffee prices.
As part of our corporate social responsibility, the society has put up a dispensary in one of its factories; (Riabai) that operates as one of its social projects. The dispensary was officially opened by Hon. Njeru Ndwiga, then Minister for Cooperative Development and Marketing, assisted by Hon. Njenga Karume, then Minister for Defence, on 27th October, 2007. Fairtrade premiums are used to buy drugs and the dispensary attends to over 200 patients daily.
