A minor wastewater discharge was reported Monday to the Environmental Protection Division, according to a press release from the city of Richmond Hill.

The discharge occurred Saturday, Dec. 5, in a "ditch segment in the vicinity of 13802 Highway 144, contiguous to a retention pond draining to Sterling Creek." 

The cause was a broken sewer force main.

The city said less than 8,000 gallons were discharged. 

Corrective action was taken. The "broken section of pipe was replaced." The city said 6,000 gallons of discharged water was recovered from the retention pond and returned to the collection system for treatment. "The affected area was neutralized with calcium hydroxide."

No further discharge occurred.
