Clearford One - A solution capable of collecting, transporting and treating all domestic wastewater in low water supply areas such as rural communities

The vast majority of villages, towns and cities in India and in many parts of the world do not have efficient wastewater collection networks or treatment plants, as the water supply is often too weak in the pipe network. Over time, this leads to congestion of the pipe networks and the failure of the infrastructure.

Clearford, has spent 25 years developing and installing its unique, proprietary sewage collection, treatment and recycling system to tackle this very issue. The Clearford One solution works on the principle of decentralized sewage collection and has three major components: underground ClearDigest Smart Digester tanks, a ClearConvey network of sealed HDPE piping and an end of the line ClearRecover Wastewater Treatment Plant (STP) dedicated to recycling as much of the water as possible improving water security. This step-by-step decentralized process offers many advantages over traditional sewerage collection and treatment systems and allows effective sewerage coverage helping achieve SDG 6.
