Living Water Treatment Systems

Product Description

The Living Water™ Treatment System (LWTS™) is a small-scale water treatment plant. Similarly to municipal treatment facilities in developed countries, this unit relies on filtration and chemical disinfection for production of safe drinking water. Filtration physically removes particulate and bacteriological contaminants, while chemical disinfection neutralizes any remaining pathogens and ensures the treated water is safe to drink. When operated properly, the LWTS™ will provide a community with safe drinking water for many years.

Lifecycle

System should be operational for up to 20 years. No warranty or disposal information included. Interview with representative

Manufacturer Specified Performance Parameters

Each system can serve a community of about 3,000 people, treating 10 gallons/minute, up to 10,000 gallons per day. The manufactures specify that the system can be setup in less than an hour and can be operational in three hours.

Vetted Performance Status

Unknown

Safety

The system aims to provide safe drinking water, but if the system malfunctions and one of the operations of the treatment system does not properly treat the water, the resulting water may be unsafe to drink/use.

Complementary Technical Systems

The treatment system can be used in combination with oxidation to remove iron and manganese from boreholes.

It’s great they mention field testing and identify their partner. Would be great to have more information about the field testing. Field testing can mean a process through which user needs are truly identified at a time in the design process when they can be acted upon, or it can mean cursory testing late in the game merely to give the appearance of user input on a product which is basically complete.

GENERAL:
– “Protozoan removed” should be changed to “protozoan cysts removed”
– References for the bacteria, virus, and protozoan cyst removal would be helpful.
– “End of Life Indicator” is formatted differently here. One says “N” and one says “No.” Similarly, some say “logs” in the organism removal row, and some just list a number.

LIVING WATER:
– For turbidity, this document (https://watermission.org/wp… claims that treated water is always <1 NTU.
– I question whether there is “high” academic research about this. The website has many links to posters, but these are overall not high quality studies.

ROAM FILTER:
– Listing “0” for unfiltered water and safe water storage capacity is a little odd. I think that should be changed to N/A if it is not provided.

DAY ONE WATERBAG:
– “User provision model” lists direct sales, however, further down, the pricing lists only “Donation only.” That is unclear.
– It seems unrealistic that a target user would be a community. This seems like more of an individual or household intervention.
– There is quite a bit of academic research about the P&G Purifier of Water packet – although not this configuration of it.
