It must be remembered that "redesigning the toilet to reduce the amount of
water consumed" is not simply a matter of bolting a lower volume cistern
onto an existing WC bowl. The geometry of the bowl itself will have to be
changed. An you will have to consider the effect your new WC will have if
it is installed in an existing drainage system. I found these two
references for you:
Swaffield, J.A., (1993) Water closet characteristics & performance - a
synthesis, CIBW62 Water Supply & Drainage for Buildings, Porto, Portugal.
Greywater & rainwater recycling systems, BSRIA Bulletin, Sept. 1997.
Good Luck
