In this shell script:

> printf "a a a\nb b b\nc c c\n" |

> echo "$x: ($i)"

-------------------------------
By pipe'ing the commands together, you cause the while loop to be executed in a subshell. Change your script to be:
#!/bin/bash
i=0
while read x
do
i=$[i+1]
echo "$x: ($i)"
done << _EOF_
a a a
b b b
c c c
_EOF_
echo $i
