Erie Water Works

July 17, 1913:  Municipal Journalarticle. Water Purification at Erie. “The year 1912 was the second for the use of hypochlorite by the water works commissioners, of Erie, Pa., and they report that it has proved beyond a doubt the value of this treatment as a water purifier. “The treated water has at all times been free from pathogenic germs and perfectly safe to be used for drinking purposes.” From January 1 to June 9 7 pounds of hypochlorite was applied to the million gallons of water pumped. The amount was increased to 8 pounds from June 9 to October 10, after which it was again reduced to 7 pounds. The number of bacteria per c. c. in the water immediately after treatment averaged as follows for each of the  twelve months: 26, 37, 10, 20, 36. 56, 26, 26, 26, 33, 30 and 24. It was found that the number of bacteria generally increased in the mains, and water as drawn from the taps contained an average of 24 bacteria in February and 554 in June, these being the minimum and maximum monthly averages. It is extremely probable that the additional bacteria were perfectly harmless varieties. The cost of operating and maintaining the sterilization plant for the year was approximately 79 cents per million gallons of water pumped. The average daily pumpage for the year was 15,679,132 gallons.

On July 25, 1912. a contract was let by the commissioners for a pumping station, boilers, and 24-million gallon rapid sand filter plant, the contract price of which was $446,380. Part of this contract is completed, and the whole is expected to be finished by next spring.”

Commentary:  Erie was one of the many cities who jumped on the chlorination bandwagon and then realized that they also need to filter their water to fully protect their customers.
