By Katie Davies PUBLISHED: 17:13 EST, 7 March 2013 | UPDATED: 07:53 EST, 8 March 2013 A community-minded couple, who won an eye-watering $136.5million with a Powerball ticket, have broken with the fast car, fancy house tradition of lottery spending by investing in a sewage treatment plant. Mark, 52, and Cindy Hill, 51, have decided to use their new-found wealth to improve Mark's hometown of Camden Point, Missouri, which is home to fewer than 500 residents. They live in nearby Dearborn. City officials were estimating it would take around 25 years to complete the treatment works so the couple stepped in donating $50,000. It will allow families in the town to do away with individual septic tanks.
