Where does the light and ventilation come from?
Each toilet unit has a translucent roof and provides natural light and illumination of more than 400 lux., calculating out to mean the transparency is in the 30% range.  Providing a light bulb in a toilet would prove to be an expensive proposition 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 two vents on each side.

How is the toilet cleaned?
The portable toilet cabin being a main free unit (meaning it does not need to be connected to a septic tank or sewer line) has to be evacuated or cleaned from time to time using a vacuum driven system, which is provided Diamond Environmental where the toilets are situated

How can 100 plus people use it continuously without the waste being evacuated?
The portable toilet unit contains a waste tank. 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 solid waste considerably. The bio chemical liquid also has a pleasant fragranced aroma keeping the toilet unit in pristine condition and 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.

Does the cleaning service cost money?
All good things come for a price and so does Diamond’s cleaning service. The cleaning service consists of a waste collection tank mounted on a truck 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 services provided. Unless otherwise stated, your base quote includes one time per week service.

What is the difference between a drop tank, a re-circulating tank and a fresh water tank?
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. Often referred to Porto-Let, Port-O-Potty, Portable Restrooms, Portable Toilet, J-John or one of many other nicknames, the system has no flushing facility.  Hand wash 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 takes the deodorized liquid and provides home-like flushing.  In this tank, fresh water 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. 

Where can the units be installed?
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, golf tournaments, entertainment shows, concerts, public rallies, election campaigns, places where construction is not permitted or possible, construction sites, beaches, tourist spots, parks, high ways, etc.
