Climate Smart Waste Management

Sustainable Sanitation for Homes and Institutions

Managing human waste has long been a challenge, especially for schools, institutions, and communities without access to modern sanitation infrastructure. Traditional pit latrines fill up quickly, produce foul odors, and pose a serious health risk by contaminating underground water sources. Diseases like cholera and typhoid often thrive in such conditions, endangering nearby populations.

Bio-San systems offer a cleaner, safer alternative. Expertly engineered for both domestic and institutional use, these systems provide an eco-friendly, hygienic solution for human waste management—without the hassle or environmental harm of conventional latrines.

How Bio-San Works

At the heart of the Bio-San system is a multi-stage anaerobic digestion process. Waste is held for a minimum of 90 days to allow for full decomposition, fermentation, and pathogen elimination. The result is a safe, fully treated liquid byproduct.

To respect cultural concerns and maintain hygiene, we recommend using this treated water for irrigating trees, fodder crops, and live fencing—not food crops. The system’s design utilizes a sealed digester and underground “French Drain” irrigation, feeding water directly to plant roots. This not only boosts nutrient absorption but also prevents groundwater contamination.

Key Benefits of Bio-San Systems

• ✅ Never fills up or requires emptying – No need for exhausters.
• ✅ Works in all terrains – Ideal for rocky or high water table areas.
• ✅ Quick to install – Comes prefabricated for easy setup.
• ✅ Cost-effective – A smart alternative to traditional latrines.
• ✅ Eco-friendly irrigation – Treated liquid can water trees and fences.
• ✅ Maintains a clean, odor-free environment.

Grey Water Treatment for Kitchens and Showers

Bio-San systems also treat grey water from showers and kitchen sinks using a specialized anaerobic treatment process enriched with Effective Microorganisms (EM). With a 40-day retention time, the system breaks down soaps, oils, and organic matter—completely eliminating harmful pathogens, as verified through lab testing.

This treated grey water is ideal for safe irrigation, contributing to water conservation and sustainability.

Beyond Sanitation: Bio-San Gas Systems

For institutions with high waste output—like schools, churches, children’s homes, markets, and prisons—our Bio-SanGas plants offer an added benefit. These systems not only manage waste but also convert it into biogas, which can be used for:

• 🔥 Cooking and heating
• ⚙️ Powering machines like chuff cutters and hammer mills
• ⚡ Generating electricity

The system is scalable, with plant sizes tailored to the number of users. Additionally, the nutrient-rich byproduct can be safely used to fertilize lawns, playgrounds, fruit trees, and hedgerows.

Domestic Bio-San: A Hygienic Pit Latrine Replacement

Our domestic Bio-San systems are a simple, affordable upgrade from traditional pit latrines—especially in rural and peri-urban areas. These systems feature a multi-chamber digester that fully liquefies waste, ensuring:

• 💧 Continuous operation without ever filling up or needing emptying
• 🌱 Safe, nutrient-rich liquid directed to shallow French drains for irrigation
• 🚫 Reduced pollution of rivers, lakes, and underground water
• 🛠️ Fast, easy installation—even in rocky or high water table areas
• 🏡 Perfect for homes with 5–6 people

This technology not only prevents water contamination but also helps combat invasive plant growth like the water hyacinth in Lake Victoria by stopping nutrient runoff at the source.

Spreading the Solution

We’re empowering local communities by training youth groups and community-based organizations (CBOs) to implement this clean, simple technology where it’s needed most.
