Scaling Resource Efficiency and Cleaner Production (RECP) in the Nairobi Rivers Basin
- Last updated on 26 February 2025
Background Information
The Kenya National Cleaner Production Centre (KNCPC) is leading this Nairobi-based project which is designed to pilot solutions for water pollution caused by the discharge of untreated/poorly treated industrial effluent by multiple industry types. The project falls under the umbrella of the Nairobi Rivers Basin Commission, launched by President William Ruto in February 2023, to reclaim the rivers of Nairobi as a spine to the city’s blue and green infrastructure for a better urban environment and quality of life.
From experience, KNCPC understands that manufacturers struggle to adopt progressive improvements and investments into cleaner infrastructure for a range of reasons – poor organisational capacity, lack of understanding of the most suitable technology to address their needs, and low understanding of the long-term commercial benefits. The challenge of limited information and understanding of the commercial business case is shared by the financial sector, with the result that financing is not readily available for required investments in Resource Efficiency and Cleaner Production (RECP).
The project kicked off with a scoping exercise to map the most urgent water pollution challenges and the priorities in the basin. Priority industries were invited to work alongside the project, specifically to receive support from KNCPC in the form of site evaluations, recommendations on RECP interventions and staff training on these practices. The KNCPC aims to work with up to 100 manufacturers for RECP training and audits. Sites are audited for specific infrastructure investments and an assessment is made on what type of financing solutions are suitable and what investment readiness interventions may be required to support this. The project partner, Fintech Frontiers, will be developing a case for the return on investment and facilitate engagement with financial partners. By bringing finance providers on board and providing specific training to investors on the business case for cleaner production investments, the project seeks to address a significant barrier to physical investments in pollution abatement. With better information on the water pollution situation in the Nairobi Rivers, the project will also bring policymakers into the discussion to address policy incentives and better regulatory control.
The broad scale work is paired with targeted wastewater treatment interventions at two pilot sites. These pilot sites will be used to build case studies and as demonstration sites that will illustrate environmental compliance benefits and the long-term financial benefits of circular water use and greater resource efficiency. The wastewater case studies will be used alongside the broader campaign to implement RECP practices amongst the heaviest polluting industries in the Nairobi Rivers Basin and to show the potential for large-scale environmental improvements in the water quality of the Nairobi Rivers.

Updates
The project has mapped 224 industries operating along the Nairobi Rivers Basin which runs across 5 counties – Kajiado, Kiambu, Machakos, Makueni and Nairobi. One hundred and twenty-one of these industries were selected for wastewater assessments. Most of the industries assessed fall under 4 sub-sectors, namely food processing, pharmaceutical, abattoir and chemical. The findings from the assessments revealed that:
- 100 of these industries have wastewater treatment plants installed, however there are improvements required to meet NEMA requirements
- 85 are connected to the public sewer
- 9 are sewerage handling companies
- 74 are compliant with NEMA BOD limit of 500 mg/l
- 54 are compliant with the NEMA COD limit of 1,000 mg/l
- The estimated pollution levels for the 121 industries are 130,718 tonnes/year for Biological Oxygen Demand (BOD) and 1,809,295 tonnes/year for Chemical Oxygen Demand (COD).
From the 121 industries who participated in the wastewater assessment, 80 industries participated in training provided on cleaner production and wastewater treatment, 25 industries signed partnership agreements to participate in detailed RECP audits. To date RECP audits have been conducted for 17 industries. The RECP audits focus on the five thematic areas – water and wastewater management, energy efficiency, greenhouse gas emissions, material and solid waste management, industrial symbiosis, and environmental compliance.
The first pilot wastewater treatment plant under this project, is fully operational at Ultravetis East Africa Ltd, a pharmaceutical, animal health company operating in the Nairobi County. Since the successful installation of the wastewater treatment plant, suspended and organic pollutants from the manufacturing processes have been significantly reduced from the Ultravetis East Africa Ltd wastewater stream. Treated wastewater is now compliant with NEMA’s Fifth Schedule Standards (sewer discharge) and is being reused for non-critical processes (cleaning, toilets). Preparation for the installation of the wastewater treatment plant at the second pilot site is ongoing.
Financial advisory: Consultations with local commercial banks and data collection from the industries are underway, to inform the development of financial and credit assessment models suitable for financing the uptake of resource efficiency and cleaner production.
Stakeholder workshop: Project findings were used to facilitate dialogues with policy makers, on policy and regulatory frameworks that can increase the adoption of RECP and advanced wastewater treatment.
The project has ongoing engagement with various stakeholders in its activities these include the National Environmental Management Body, Nairobi Rivers Commission, Water Resource Authority, Kenya Association of Manufacturers, Kenya Private Sector Alliance, Kenya Bankers Association, respective county governments, and water and sewerage companies.
