Sanitation & Drainage, Re-Engineered
Three engineering innovations developed by Sisal Engineering and Construction to solve the wastewater and sanitation problems conventional systems leave behind — researched, improved and proven in Ghanaian conditions.
Drainage and Sanitation Solutions in Ghana
SISAL Engineering and Construction provides drainage and sanitation solutions in Ghana through three purpose-designed systems: the Sisal Biomechanical Drainage System (SBDS), Mechanized Biofil Toilet System and Mechanized Septic Tank Toilet System. Developed to address wastewater and sanitation challenges, these systems serve residential, commercial and institutional properties, with options designed to work even in challenging conditions such as waterlogged clay soils.
Mechanical filtration plus biological treatment for domestic wastewater — reliable even in clay and waterlogged soils.
- Ends soakaway clogging & failure
- Protects groundwater
- Long life, low maintenance
An advanced onsite biofilter toilet, re-engineered for better treatment, easier maintenance and longer service life.
- No pit, no tanker
- Easier to maintain
- Compact & eco-friendly
An improved septic-tank system that treats better, needs less desludging and lasts longer than conventional tanks.
- Less desludging
- Reduced odour
- Cleaner effluent
Choosing the Right System for Your Property
Effective drainage and sanitation solutions in Ghana begin with understanding your property – soil conditions, groundwater levels, available space, expected usage and maintenance access all influence the selection, particularly on sites with waterlogged clay soils.
Engineered here, proven here.
We developed them
Researched and improved by our own engineers — not imported off the shelf.
Treat, not just store
Biological and mechanical treatment on site, instead of storing waste until it fails.
Cheaper over time
Less emptying, less maintenance, fewer failures to fix.
Built for hard soils
Reliable performance in clayey and waterlogged ground where others struggle.
Solve it properly, once.
