Clearford in India

Clearford has developed an innovative and practical solution for the vast sanitation challenges in India, such as low water usage and intermittent availability of electricity for pumping and treatment. The Company’s primary offering, Clearford One, is a packaged decentralized communal sewage system that has lower capital, operating and maintenance costs than conventional systems. Clearford has refined and proven its proprietary Clearford One technology over more than 25 years of in-the-field operating performance.

The Clearford system is proven to be effective in India and is ideally suited to bring adequate sanitation to approximately 600 million Indian citizens who live without it. Clearford One has many advantages over conventional sewerage collection and treatment systems, and for the first time enables the affordable and sustainable deployment of large scale communal sanitation across India.

 Clearford One is equally suited for:

  • Residential townships,
  • Urban areas,
  • Villages and towns, and
  • Resorts and campuses.

It is estimated that at least 70% of all diseases in India are related to water contamination and poor sanitation.

It is estimated that inadequate sanitation translates to Rs. 324,000 crore in economic losses per year to the Indian economy.

The Challenge

The majority of people in India live in rural villages, small towns, and along the edges of India’s growing cities. These places have many common features that present challenges for sustainable sanitary servicing, including:

  • Organic unplanned growth, presenting challenges for infrastructure planning and construction;
  • Low water supply, making it difficult to transport sewage solids through conventional sewers;
  • Intermittent or no availability of electricity, requiring off-the-grid technologies;
  • Limited or no private sanitation facilities, encouraging open defecation practices; and
  • Social barriers related to the use of sanitation, slowing down the adoption of sanitary services.

The Clearford One Solution

Clearford One is a proprietary sewage collection and treatment system that overcomes the challenges of how to sustain sewerage networks in areas of low water supply, while helping to mitigate the loss of life and income earning opportunity caused by illness.

Clearford One works on the principle of decentralized wastewater management and has three major components:

  • ClearDigest Smart Digester tanks,
  • ClearConvey network of sealed HDPE piping, and
  • ClearRecover sewage treatment plant (STP) dedicated to augmenting available water resources and the reuse of treated water for irrigation.

Clearford also offers a fourth component that is often overlooked in sanitation solutions for India—private sanitation facilities, such as toilets, showers and wash basins. The design and integration of these facilities is critical in promoting the successful adoption of sanitary servicing where safety and social barriers exist to healthy sanitation practices.

These components work together to form Clearford One, which provides a solution to the sanitation challenges in India by:

  • Allowing for flexible deployment to retrofit existing communities;
  • Operating with low power and water requirements;
  • Providing modern financially sustainable sanitary servicing for a variety of urban and rural communities; and
  • Delivering sanitation under a consultative model that involves, educates and engages local communities in the process.
