April 28, 1909: Municipal Journal and Engineer article. Electrolytic Treatment of Sewage. By C.B. Irvine. “After a practical operation of the magneto-electrolytic sewage purification plant at Santa Monica, Cal., covering a period of nine months, figures are obtainable going to show the actual cost of maintaining the plant. For sixty days prior to September 1 of last year the device was operated by its builders, at the expense of the city. This was the trial test upon which the decision to purchase the system was based, and as it proved satisfactory to the City Council, the purchase was made at $10,000. On September 1 the city took charge of the plant and has since been treating twenty-five miners’ inches of sewage daily. The capacity of the plant is great enough to care for a million gallons in a twenty-four-hour day, but the quantity supplied by the 11,000 inhabitants of the city does not exceed one-half that amount. The cost of operating the plant is found, upon actual experience, to be approximately $400 per month…. The City Council has expressed itself as being entirely satisfied with the operation of the plant, which is being visited every few days by delegations from Southern California cities, while inquiries are received from all parts of the globe.”

Commentary: At the turn of the 20th century, cities across the U.S. were being conned by unscrupulous charlatans who claimed that running a little electricity into sewage would fix it up just fine. It is a little embarrassing that this example is from my home town of Santa Monica, California. With only 11,000 residents, Santa Monica was a little beach town during this period with a big pier.
