Each toilet unit has a translucent roof and provides natural light and illumination of more than 400 lux. Besides, providing of a light bulb in a toilet will prove to be an expensive proposition for the supplier taking into consideration the mentality of the public at large and the vandalism that one sees in our country today. The toilet also has enough ventilation, which is provided on three sides of the toilet and that too very discreetly to give the user total privacy and avoid peeping toms. The vents are situated at the junction of the roof and the panels. There are 3 vents on each side.

The number of people using the units varies from 75 uses to 150 or more uses depending on the model of the toilet. The KROS Urinal has a waste capacity of 450 liters and is purely a urinal, which can accommodate about 300 to 350 users at a time without cleaning or evacuation.

The toilet cabin being mains free unit (need not be connected to septic tank or sewer line) has to be evacuated or cleaned from time to time using a vacuum driven system, which is provided by the service provider in the city where the toilets are situated for exclusive cleaning service a minimum of 30 toilets need to be purchased.

The unit contains a waste tank of varied capacity. Before the unit is used (at the time of cleaning session) the tank is charged with an eco friendly biochemical additive which helps in degrading the solid waste considerably. The bio chemical liquid also has a mint or cherry aroma keeping the unit in pristine condition preventing foul smell. It is absolutely bio degradable and not harmful to the environment, drainage or the treatment plant where it is safely disposed. The bio chemical solution is Formaldehyde free and is at par with international waste regulations.

All good things come for a price and so does this unique cleaning service. The cleaning service consists of a waste collection tank mounted on a vehicle coupled with a vacuum pump, which evacuates the waste and also cleans the toilet with fresh water using a high pressure jetting system. The cost is very minimal as compared to the value of the privilege and services provided. An annual cleaning contract can also be worked out at a very reasonable price.

All the above are types of waste tanks and their systems. A drop tank is an open tank, which has no frills and like the name suggests it is used as a popular toilet for construction sites, roadsides and places where one needs to have a quick job and get on with it. The system has no flushing facility as the waste contents are literally dropped to the bottom of the tank. Water can be provided inside this particular unit with a capacity of about 100 liters. The water though can be used only for hand wash and for washing of ablutions. It cannot substitute a flush. The Re-circulating tank is a water saver. In this tank, fresh water (about 10-20 liters) is run into the waste tank. The bio-chemical is then added to this water, which turns it blue. The unit is now ready for use. As the unit is used the solid waste settles down to the bottom of the waste tank leaving the clear water above. The unit has a re-circulating system, where as the name suggests - the clear water is re-circulated from time to time when the flush is engaged and clear water, which is blue in color, effectively arrives in the cistern and cleans it. After a number of uses, the color of the water starts becoming yellowish, this is an indicator to inform the cleaning service for evacuation. Fresh water Flush is exactly like the flushing systems in our homes. There is a separate water tank, which is provided inside the unit and every time the flush is engaged, fresh water arrives in the cistern and cleans the toilet bowl and settles in the waste tank. The waste & water is not reused like in the re-circulating tank.

If required the unit can be attached to the sewer line or septic tank.

Just about anywhere. In places where there is no drainage line or septic tanks and where providing good sanitation is a must. Busy streets, shopping areas, camps, outdoor events like marriages, festivals, yatras, entertainment shows, concerts, public rallies, election campaigns, places where construction is not permitted or possible, construction sites, beaches, tourist spots, parks, high ways, etc.
