Aquamet Sanitation Ltd designs, supplies, installs, commissions and maintains decentralised wastewater treatment systems for homes, institutions and industry across Kenya and East Africa. We're not just a water treatment company — we're a water conservation company.
Aquamet Sanitation Ltd is a Kenyan environmental engineering company specialising in decentralised wastewater treatment. Our solutions combine biological and mechanical treatment technologies to safely treat black and grey water for environmental discharge or reuse in irrigation, landscaping, toilet flushing and other non-potable applications.
With more than six years in the field, an experienced technical team and a track record of hundreds of successful installations, we deliver systems that cut water and sewer costs, need little maintenance and last for decades — while protecting the environment they sit in.
To become East Africa's leading provider of innovative, sustainable wastewater treatment and environmental engineering solutions.
To deliver affordable, reliable and environmentally responsible sanitation solutions through engineering excellence, innovation and exceptional customer service.
Every unit is sized and customised to your site, your user load and your reuse goals — then built to last with quality workmanship.
Durable in-ground concrete biodigesters that break down black and grey water on site through anaerobic digestion — no sewer connection required. Sized from a single household up to large institutions.

Final-stage filtration that removes suspended solids before discharge or reuse, improving effluent quality and protecting downstream soak pits, drip lines and irrigation systems from clogging.
Ask about specs →
Aerated bioreactors for secondary wastewater treatment, driving down organic load (BOD/COD) to produce a clear, low-odour effluent suitable for reuse or safe environmental discharge.
Discuss your load →
Sequencing Batch Reactor plants that perform every treatment stage in one tank on a timed cycle. Ideal where a soak pit won't work — swampy ground or low-permeability soils — delivering odour-free water for irrigation and toilet flushing.
Plan a plant →
Complete treatment-and-recycling trains that turn wastewater into a reliable non-potable supply for landscaping, toilet flushing and washdown — cutting fresh-water demand and utility bills.
Explore reuse →One accountable partner for the whole lifecycle of your wastewater system.
Site assessment, hydraulic and process design, and full installation of decentralised wastewater treatment systems tailored to your development.
Purpose-built concrete biodigesters engineered for your user load, soil conditions and available footprint — delivered ready to use.
Rehabilitation and upgrading of failing or undersized septic tanks and soak pits into efficient, compliant treatment systems.
Supply and commissioning of aerated bioreactors for reliable secondary treatment and high-quality effluent.
Capture biogas from your digestion process and put it to work — adding a renewable energy return to your sanitation investment.
