Idea for a new Eco-Toilet

Recently I saw a news item in Times of India (12th Oct 2014) about saving water by peeing in the shower. When I googled it there were many who were supporting this idea for conservation of water. Hence I am encouraged to publish as a blog, my earlier idea of 2010, for an Eco-Toilet.

New Design for an Eco-toilet

 The goal is to conserve the use of water in a flush-out toilet commode.

The idea is to revise the design of flush out toilets. Millions of people use flush-out toilets (Indian or Western Type). While the amount of water required to flush the solid waste is very high, we do not need the same amount of water for urinating purpose. Though a few designs were made earlier to provide two flush systems in the toilet for major and minor uses, these designs were neither popular nor very successful. The amount of water wasted is enormous as minor uses are about ten times more than the major uses in a day. Hence this suggestion is for the following rough design of a new eco-toilet.

Ecotoilet

The pot can be divided into two compartments 1 and 2. The outlets of pot-1 can directly drain into the main drain through a separate smaller s-bend and then to the septic tank. The pot-2 can flush out the solid waste through the normal siphon system. This way pot-1 needs much less water as in any normal urinal. Even a mug of water will do the job. A dual flush system could be an added facility. Both the smaller and bigger s-bends are integrated in the same ceramic mold and will hold water in the bend to seal off septic tank from the toilet

Implementation: This idea can be implemented by all the people who have access to toilets with septic tanks. The sanitary engineers should study this suggestion seriously and come out with more practical and feasible designs. All the commode manufacturers should readily come forward with their own implementation of the design to suit various customer segments. The manufacturers, suppliers and distributors should give hefty volume discounts for mass implementation of this design in all apartment blocks in urban areas. The government may also subsidize the cost for poorer sections of the society, who have common toilets. The removed older commodes may be re-used in public toilets where separate urinals are provided in addition to commodes.

Partners: The commode manufacturers, builders, civil contactors, housing societies, municipality health inspectors, plumbers and masons should all be involved in evolving a suitable design, implementation and practice.

All the new apartment blocks, including those under construction can be asked to implement this design as a precondition to issue of occupation clearance certificate. Apartment blocks in the urban area may be asked to implement the design in a phased manner, say in about three years.

The cost of manufacture of this kind of toilets will only be marginally higher than the normal ones. Depending on the aesthetics of the design to suit different markets, the actual costs may vary. Because of a very large initial demand the cost per unit will come down drastically. With exchange offers and deserving subsidies, the cost may not pose a big problem.

Outcome of this modification: This design of toilet will save a lot of water for our future generations at the same time keeping our toilets adequately clean and hygienic.
