The City of Quincy is helping to ensure safer drinking water for residents.
The city recently put a new $3.5 million solid contact clarifier into operation.
It's a treatment process used to soften the water and to remove silt from the river, purifying the water before it goes to filters.
Prior to the new process, Quincy City Engineer Jeffrey Conte says the city was down to just one clarifying unit, which dated back to the 1950s. Now, the city will use that one as a back-up in case the current one fails.
"The one that we have right now needs to be taken out of service periodically to clean," said Conte. "When we do that, we can't make any water. We're always under the gun to get it cleaned out as quick as possible to get the treatment plant back up and running."
The new clarifier was paid for with a low interest loan from the EPA.
