John Waweru Gakunga

Founder and Managing Trustee

John Gakunga has passion on urban waste engineering,rural/urban water,sanitation and hygiene issues;waste to energy in cities for sustainable developments, projects/construction management and infrastructure developments, with a keen eye on environment challenges and best practical solutions for keeping our planet pollution free.

Our concerns are environmental challenges caused by urban solid wastes, wastewater, WASH, agriculture/irrigation, DEFORESTATION and chemical and hazardous wastes sectors in Africa. We target waste to energy schemes, urban waste, wastewater engineering, land filling engineering, land fill gas, dump sites rehabilitation; with development of mechanism for reduction of GHG Emissions in developing countries; anaerobic digestion and Bioelectrochemical systems, education, research & development and training young men and women in these sectors in Africa.

John is a member of International Solid Waste Association (ISWA) among others and shares the same objectives as ISWA and cares for the following causes -Arts and Culture, Children, Education,Environment, Health, Fairness to all, Poverty eradication, Science and Technology, Social Services and Youth Motivation,,

She completed her high school education at Kangaru High School, Embu in 1980 after which she got admitted at McGill University, Montreal, Canada, to pursue her undergraduate studies. In 1985, she graduated with a Bachelor’s degree in Civil Engineering (B Eng – Civil Engineering) and she immediately secured a job with the then Ministry of Water Development in Kenya, where she worked as an Assistant Engineer till 1987 when she joined Kenya Water Institute (KEWI) as a lecturer.  In 2005, while at KEWI, she enrolled for her post graduate studies at Jomo Kenyatta University of Agriculture and Technology (JKUAT), where she graduated with a Master’s degree (MSc) in Environmental Engineering and Management in 2009. She then joined Kenyatta University as a lecturer in 2010 and in 2012, she was appointed to head the Civil Engineering Department, an appointment she held till November 2014 when she joined the Tshwane University of Technology (TUT) to pursue her doctoral studies in Civil Engineering – DEng (Civil Engineering). In her doctoral research, Catherine focused her investigation on the ability of four (4) emergent mcrophytes; Vetiveria zizanioides, Phragmites australis, Typha latifolia and Cyperus latifolius in the removal of toxic heavy metals Cd, Cr and Pb from synthetic wastewaters in experimental constructed wetland units. Catherine is an author and co-author of five scientific publications.

Catherine currently heads the department of civil engineering at Kenyatta University (KU). She has steered the development of curricula in Civil, Petroleum and Aerospace Engineering, programs that are currently in use at KU. She is also involved in the development of Competency Based Curriculum (CBC) in Water related areas as a Sector Skills Advisory Committee (SSAC) member.
