INTRODUCTION

About 32.7% of Indian population lies below the poverty line Sanitation needs completely depends on public sanitation

centers Currently, in India, they could not find the hygienic

situations, which later on results in their health related disparities.

India- with 1.2 billion people – is far from achieving it.

Less than one-in-three households in Indian villages have toilets.

Urban areas have more toilets but nevertheless suffer from poor sanitation and disposal mechanisms.

The lack of public toilets for the urban poor and in rural areas leads to alarming rates of waterborne diseases and affects women and children most.

NIRMAL GRAM ABHIYAN-in rural areas

But, still the urban conditions are very pathetic, in terms of sanitation facilities,

due to increased density of population

FLUSHING

SPRING :

Mean Diameter of the spring = 6.985 cmDiameter of the wire = 0.5 cmNumber of Coil = 15Range = 10 kg -30 kg Minimum load = 10 kg = 98.1NMaximum load = 30 kg = 294.3NNumber of springs = 2

DESIGN CALCULATION

DEFLECTION UNDER MINIMUM LOADING : 

The load of 10 kg is uniformly distributed among two springs

98.1 N = 49.05 N / springδ = {64*49.05*(3.4925)3

*15}/{(8.4*106)*(0.5)4} δ = 3.8208 cm

DEFLECTION OF SPRING

DEFLECTION UNDER MAXIMUM LOADING 

The load of 30 kg is uniformly distributes among two springs

 294.3 N = 147.15 N / spring

δ={64*147.15*(3.4925)3 *15}/{(8.4*106)*(0.5)4}

 δ = 11.46 cm

WORKING PROTOTYPE

PROS CONS

Appropriate water usage

Reduced wastage of water

Increased standard of sanitation facility

Mechanical means of operation, may cause some linkage errors

Springs may fail, on continuous operation

Frequent Loading and Unloading, leads to errors in leverage mechanism

COST ESTIMATION

SPOOL & SPRING Rs. 300

CLAMPS & FITTINGS Rs. 100

TOTAL COST/BASIN Rs. 400
