1 Use water wisely while washing, bathing and cleaning.
2 By improving the sewage system.
The best ways to clean water are found in a multi-barrier approach that protects water quality from source to consumption.

The Multi-Barrier Approach for HWTS
The World Health Organization has determined that a multi-barrier approach to household water treatment and safe storage (HWTS) is the best way to reduce the risk of drinking unsafe water.
A multi-barrier approach means ensuring that water is protected and purified every step of the way from the water source to household storage and consumption. Water quality will only be as good as the weakest link in the chain of water handling.
We need to follow a process and not just rely on a single technology to improve water quality.
Both community and household water treatment systems follow the same water treatment process. The only difference is the scale of the systems that are used by communities and households.
Introduction to HWTS
Step 1 - Water source protection
Step 2 - Sedimentation
Step 3 - Filtration
Step 4 - Disinfection
Step 5 - Safe water storage
