Display results from PS in new line

Question

I have problem to correctly display results from variable. When I use code as below then results are in one line as below.

httpd=`ps -wweo uname,pid,pcpu,pmem,args | sed -e 's|/usr/pw/apache/bin/httpd.*|httpd|' | grep -E -w 'httpd' | grep -v 'grep' | grep -v 'sed' | sed -r 's/[[:blank:]]+/;/g'` 

echo $httpd
user;6374;0.0;0.0;httpd user;12571;0.0;0.0;httpd user;26473;0.0;0.0;httpd user;29933;0.0;0.0;httpd user;31980;0.1;0.0;httpd

Without variable results are OK and this is what I execpted

  ps -wweo uname,pid,pcpu,pmem,args | sed -e 's|/usr/pw/apache/bin/httpd.*|httpd|' | grep -E -w 'httpd' | grep -v 'grep' | grep -v 'sed' | sed -r 's/[[:blank:]]+/;/g'
    user;6374;0.0;0.0;httpd
    user;12571;0.0;0.0;httpd
    user;22984;0.0;0.0;httpd
    user;26473;0.0;0.0;httpd
    user;29933;0.0;0.0;httpd

Is there any trick to fix my results? Thank you
