(CNN) An executive who paid $250,000 to get his son into the University of Southern California falsely as a water polo player was sentenced to four months in prison as part of the college admissions scam, a federal judge ruled Tuesday.

Devin Sloane, the founder and CEO of a provider of drinking water and wastewater systems, also must serve 500 hours of community service and pay a $95,000 fine, the US Attorney's Office for the District of Massachusetts said.

Sloane pleaded guilty to conspiracy fraud in May. Prosecutors had recommended he be sentenced to one year and one day in prison, a year of supervised release, a fine of $75,000, forfeiture and restitution.

Sloane is the second parent to be sentenced in the college admissions scam, and his sentence represents the most significant punishment so far in the case. Earlier this month, the actress Felicity Huffman was sentenced to 14 days in prison , 250 hours of community service and a $30,000 fine for paying $15,000 to the scam's mastermind to boost her daughter's SAT scores.

A total of 35 parents have been criminally charged as part of the sprawling investigation into the scheme to cheat, bribe and lie to get an advantage in the college admissions system.
