The Eaziflush has an incorporated child seat lid. The product can be connected to any backend but according to manufacturer it fills a pit a third of the speed of a corresponding VIP latrine.

Manufacturer Specified Performance Parameters

When the Envirosan is connected to a pit, the pit lasts twice as long as a VIP pit. The Eaziflush only requires 2 L of water per flush. The manufacturer designed the toilet to:

- look and operate similar to a flush toilet
- eliminate odor due to the water seal
- be safe for children
- have a low risk of blocking when using toilet paper or newspaper
- have multiple back-end options
- demand minimal user intervention
- save water

Vetted Performance Status

The Eaziflush only needs 1-2 L of water per flush depending on the type of excreta and paper used.

Safety

Compared to VIP toilets, user safety is increased due to water seal in U-trap between user and waste pit. The water seal prevents flies from entering the facility and keeps waste away from the user. Children are also protected from the hazards of falling into waste pits and exposure to decommissioned, full waste pits. Community members are calling it "the safe toilet".

Complementary Technical Systems

A child toilet seat is incorporated into the design which features a lid, child seat, and adult seat. The toilet has to be connected to a sewer system or a storage of some sort.
