Water Supply and Sanitation Engineer
Water Supply and Sanitation Engineers design, construct, and maintain systems that deliver clean water and manage wastewater, ensuring public health and environmental protection. In Kenya, they address critical water scarcity and sanitation challenges through projects ranging from rural boreholes to urban treatment plants. Their core purpose is to create sustainable water infrastructure that supports communities, industries, and agriculture.
Daily tasks involve site assessments, hydraulic modeling using software like EPANET, water quality testing, and project management. Engineers work closely with contractors, government agencies, and communities to oversee construction of piped water schemes, sewer networks, and sewage treatment facilities. They also monitor system performance, conduct repairs, and ensure compliance with safety and environmental standards.
Career growth is robust due to Kenya's Vision 2030, devolved county governments investing in water services, and donor-funded programs. With rapid urbanization and climate change straining resources, demand for these engineers is high. Experienced professionals can advance to senior project manager, consultant, or policy advisor roles, with salaries ranging from KES 800,000 to 2.5 million annually depending on experience and sector.

The trade offs
In its favour
- Critical infrastructure role with stable government and donor-funded projects, ensuring consistent employment.
- Directly improves public health and access to clean water, offering deep purpose and community respect.
- Opportunity to work in diverse settings from urban Nairobi to rural Kenya, with field allowances adding income.
- Growing focus on climate-resilient water systems, opening new specializations and funding.
- Automatic problem-solving everyday keeps the job engaging, from pipe networks to treatment plants.
Against it
- Frequent field assignments in remote areas with poor roads and long travel times, impacting work-life balance.
- Bureaucratic delays in procurement and permits slow down project implementation, causing frustration.
- Salaries in public sector are modest (KSh 50k-100k/month) unless supplemented with consultancy gigs.
- Political interference in water projects can shift priorities, making long-term planning difficult.
In practice
To become a water supply and sanitation engineer in Kenya, you typically need a Bachelor's degree in Civil Engineering (water option) or Environmental Engineering from institutions like the University of Nairobi, JKUAT, or Kenyatta University. After graduation, you must register with the Engineers Board of Kenya (EBK) as a Graduate Engineer and complete a 3-5 year supervised internship, often with county water companies like Nairobi City Water or consultancies such as Mzizi Water Solutions, before sitting for the Professional Engineer exam. Entry-level roles include assistant water engineer or graduate trainee, where you assist in designing water distribution networks or supervising borehole drilling. Many also pursue certifications from the Water Services Regulatory Board (WASREB) on water quality or a short course in GIS for hydraulic modelling to boost employability.
Career progression typically moves from graduate engineer to water supply engineer, then senior engineer after attaining PE registration with EBK. Mid-career milestones include becoming a project manager for multi-million-shilling dam or sewerage projects, or a principal engineer at a county waterworks development agency. Specializations like water treatment design, hydraulic modelling, or non-revenue water management open doors to consultancies such as Mzizi or Bura Water Solutions. A typical 10-year trajectory might see you leading a team of 5-10 engineers, managing a KES 500 million upgrade of a water treatment plant, or moving into policy advisory at WASREB. Salary grows from about KES 80,000 per month for a graduate engineer to over KES 300,000 for a senior engineer in Nairobi, with county technical directors earning upwards of KES 500,000.
Kenya's water and sanitation sector is driven by devolution, with 47 county governments as primary employers, especially urban counties like Nairobi, Mombasa, Kisumu, and Nakuru that manage water service providers. Key employers include Nairobi City Water and Sewerage Company, Athi Water Works Development Agency, Lake Victoria South Water Works, and national bodies like the Water Resources Authority (WRA). The market is large, with annual government budgets exceeding KES 100 billion under the Water Sector Trust Fund and donor-funded projects from the World Bank and AfDB targeting SDG 6. Growth drivers include urban migration, climate change adaptation, and Vision 2030 flagship projects like the Northern Water Collector Tunnel and sewerage master plans. Challenges like 45% non-revenue water and ageing infrastructure create high demand for engineers, with jobs concentrated in water service providers, consultancy firms (e.g., Mzizi, KPMG Infrastructure), and county water departments.
A typical day for a mid-level water supply engineer at Nairobi City Water might start at 7:00 AM with a field visit to the Ng'ethu Water Treatment Plant to check chlorine dosing and flow rates, then drive to Kibera to inspect a burst pipe repair by a contractor. By 11:00 AM, you're back at the office reviewing hydraulic model simulations for a new pipeline extension to Ruaka using EPANET software. After a quick lunch, you attend a coordination meeting with the Nairobi Metropolitan Service engineers to discuss sewer blockage hotspots and schedule desilting work. The afternoon includes reviewing a borehole drilling contract for compliance with Kenyan Standards (KS 03-1) and emailing weekly progress reports to the county water executive. Before leaving at 5:30 PM, you prepare a site visit report highlighting water quality test results from the Ruai Sewage Treatment Plant.
