How to use clear plastic bottles, put in sun for 8-12 hours and allow the ultraviolet radiation of the sun to kill all organic matter. Please read up on Wikipedia:

Solar water disinfection is a type of portable water purification that uses solar energy to make biologically-contaminated (e.g. bacteria, viruses, protozoa and worms) water safe to drink. Water contaminated with non-biological agents such as toxic chemicals or heavy metals require additional steps to make the water safe to drink.
There are three primary subsets of solar water disinfection:
Electric. Solar disinfection using the effects of electricity generated by photovoltaic panels (solar PV).
Heat. Solar thermal water disinfection.
UV. Solar ultraviolet water disinfection.
Solar disinfection using the effects of electricity generated by photovoltaics typically uses an electric current to deliver electrolytic processes which disinfect water, for example by generating oxidative free radicals which kill pathogens by damaging their chemical structure. A second approach uses stored solar electricity from a battery, and operates at night or at low light levels to power an ultraviolet lamp to perform secondary solar ultraviolet water disinfection.
Solar thermal water disinfection uses heat from the Sun to heat water to 70–100 °C for a short period of time. A number of approaches exist here. Solar heat collectors can have lenses in front of them, or use reflectors. They may also use varying levels of insulation or glazing. In addition, some solar thermal water disinfection processes are batch-based, while others (through-flow solar thermal disinfection) operate almost continuously while the Sun shines. Water heated to temperatures below 100 °C is generally referred to as Pasteurized water.
High energy ultraviolet radiation from the Sun can also be used to kill pathogens in water. The SODIS method uses a combination of UV light and increased temperature (solar thermal) for disinfecting water using only sunlight and PET plastic bottles. SODIS is a free and effective method for decentralized water treatment, usually applied at the household level and is recommended by the World Health Organization as a viable method for household water treatment and safe storage.[1] SODIS is already applied in numerous developing countries.
