COMPOST TOILETS

Waste per year per person= 0.27cum Approx. no. of cubicles=9 Hence, capacity of vault per cubicle=2.70cum Dimensions of each vault=1.2x1.5x1.5m

A composting toilet is a dry toilet that uses a predominantly aerobic system that treats excreta typically with no water or small volumes of flushing water via composting or managed aerobic decomposition. The human excrement is normally mixed with sawdust, coconut coir, peat moss to absorb liquids and to reduce the odour.


SOLAR TECHNOLOGY

•FOR MUMBAI 1sq. Cm generates approx 1w •Mumbai 19.12 degree N inclination • COSTS •The average solar PV system is 3.5kWp and costs around Rs. 6,46,000. • SAVINGS •A 3.5kWp system can generate around 3,000 kilowatt hours of electricity a year. It will save over a tonne of carbon dioxide every year.


Reed Bed or Planted Filter: The waste water is passed through a sand bed which contains plant species such as bamboo, canna and reeds. The roots of these plants utilize the nutrients present in waste water thus reducing the BOD (biological oxygen demand) and COD (chemical oxygen demand). The sand bed further purifies the water and the end result is clear filtered water. Advanced Grey Water Recycling System: A more advanced grey water recycling system on the other hand, requires more space and contains a septic tank, a sand filter, a pump and of course a planter bed, to then revert the treated water into field irrigation or even reused in the house as desired.

Biogas plant A biogas plant is an anaerobic digester of organic material for the purposes of treating waste and concurrently generating biogas fuel. Average size of a biogas plant=30-60cum Completely underground, with RCC structure. Production of biogas is 1 cft. Per user per day. The usual hydraulic retention time period is 30days.

Energy equivalence of biogas: 1000cft(30cum) of biogas from 1000 users is equivalent to -600cft of natural gas -6.4 gallons of butane -5.2 gallons of gasoline -4.6 gallons of diesel oil

Energy generated can be used for cooking, street lights, etc.
