We can make the section-footer sticky in Omega theme by adding the following piece of code in <your-theme>-alpha-default.css.

/* sticky footer */
html, body {height: 100%; margin: 0;}
#page {display: table; width: 100%;}
html>/**/body #page {height: 100%;}
*:first-child+html #page {height: auto;}
.section {display: table-row;}
html>/**/body .section-content {height: 100%;}
*:first-child+html body .section-content {height: auto;}

Kudos to Karl Kasischke.

Done =)
