Table 7 shows that according to individual perception, misuse of water during a shower (y1), misuse of water during a laundry (y2), misuse of water during washing dishes (y4), and misuse of water during washing cars (y6) are the significant variables that cause the water crisis in Dhaka city under ‘personal misuse’ latent variable. Under the natural crisis latent variable, ‘groundwater decreasing (y12)’ contributes significantly.
