WASHKing provides low-income and underserved communities with access to sanitation products at an affordable price. Its eco-friendly, biodigester toilets aim to end open defecation and improve poor sanitation issues in low-income urban communities in Ghana. It produces, supplies and installs high-quality biodigester toilets using locally available materials and artisans. The toilet technology uses an on-site toilet treatment solution made of a sub-structure known as biodigester and privy (super-structure) which can be built with different materials such as pre-cast slaps, Ferro-cement and blocks.

The biodigester requires as little space as 2.6 B*3ft H*5 L Sq. ft. The technology is easy to maintain as it treats human-waste on-site and does not require piping it off-site for treatment. The treated waste serves as manure and water for agricultural use, creating additional value for customers and for the environment. WASHKing aims to become a leading responsible and inclusive sanitation services brand in developing countries.

According to UNICEF, 62% of Africans lack access to adequate sanitation, and only 15% of Ghanaians have access to improved sanitation. Close to 4.8 million practise open defecation leading to deep public health, and environmental issues. This is followed by ancillary problems like risks of sexual assault, missed schooling and poverty. Where toilets exist, there are still concerns: lack of affordability, the difficulty of emptying, huge area uptake, flash-water scarcity and pollution of water resources. People in low-income areas like the urban poor suffer most as they are more vulnerable. This includes households and slum dwellers. WASHKing brings a unique and innovative solution that integrates measures of environmental, social and economic benefits by manufacturing, supplying and installing accessible and environmentally friendly toilets.

WASHKing started with 18 toilets benefiting about 150 people in Accara. It has progressed to build 200 toilets used by over 2,000 people. These toilets are not just helping to improve the poor sanitation situations in these communities but also enhancing health and income along with protecting the environment. It has also trained and engaged youth in the communities by giving them access to important transferable skills and employment.

WASHKing is at its initial production and sales growth phase. It is a hybrid between a low-profit limited company, community interest company and a social purpose corporation. Their toilet technology solution is producible by locally-available resources and is built and distributed through trained, regionally-available human resources. It sells these toilets through a face-to-face distribution network to assess potential clients’ needs and provide them with suitable facilities at suitable prices. It reaches out to low-income communities by working with partners like community NGOs, local municipal assembly and environmental health workers. They link clients to local subsidy programs and microfinance loans, run pay-as-you-use toilet service, as well as provide aftersales servicing. They provide tailored on-the-job training and employment to marginalized youth along the sanitation value chain.

The cost of building the biodigester ranges from 450 USD - 800 USD to as low as 0.12 USD for pay-as-you-use toilet services depending on the preferences and needs of customers. For its implementation, good soil like sandy or loamy soils are ideal to allow discharge of the water underground.

  • Unlike other technologies, WASHKing provides different toilet options comprising of privy building materials that meet varied preferences and financial status of customers.
  • The technology is accessible and eco-friendly producing no offensive odor and flies thus averting pollution of water resources and of the air, as well as the spread of diseases.
  • It needs no septic hauling service and associated recurrent costs.
  • It is hygienic, and not functionally biased against any population (e.g., income, gender, disabled, age and children).
  • The technology often uses as little as 500 ml of flushing water.
  • It is a suitable solution for areas with scarce land which is common among many low-income urban areas.
