#TDIWH—February 28, 1895: Los Angeles Sewer System

0228 LA Sewer system aFebruary 28, 1895: Engineering News article. The Sewerage System of Los Angeles, Cal. by Burr Bassell. “The City of Los Angeles is built upon both sides of a torrential stream, called the Los Angeles River, at a point 20 miles from its mouth. The corporate limits of the city may be described as a square, more than five miles on a side, containing 18,597 acres….

The present river channel is dependent upon artificial means for the confinement of its waters. Its bed is 30 ft. higher at the point where it leaves the south charter boundary, than at the southwest corner of the city. This change of channel is probably due to the influence of a tributary, called the Arroyo Seco, which empties its storm-waters laden with sand, gravel and boulders from the mountains on the north into the very center of the city….

The census of 1880 gave a population of 11,183, that of 1890, 50,395. A conservative estimate for 1894 is 70,000.

The first comprehensive plan for sewering the city was prepared in 1887 by Mr. Fred Eaton, M. Am. Soc. C. E., at the time city surveyor. It was designed on the separate system, with an outfall sewer to the sea, via the Centinela Rancho. His estimated cost of the internal system was $533,846, and for an outfall sewer to the ocean by the Centinela route, 11.5 miles in length, $466,154, making a total of $1,000,000.

Mr. Rudolph Hering, M. Am. Soc. C. E., reported favorably on Mr. Eaton’s plans, and stated that the problem of designing a good sewerage system for the city presented no serious difficulties.

Commentary: This article is remarkable in so many ways. Los Angeles was only 25 square miles and the population was only 70,000! Obviously, the city has grown a bit since the article was written. Incidentally, the article goes on at length to describe other sewering options. The plot plan below represented the preferred option. As near as I can tell, the outfall for this sewer is right about where the Los Angeles International Airport (LAX) is now located.

Mr. Fred Eaton went on to play an infamous role in Los Angeles water wars. In 1905, Eaton was a central character in the purchase of the Owens Valley lands that formed the basis for the Los Angeles water supply imported from the Eastern Sierras. Eaton’s actions were conducted under the inappropriate cloak of respectability of the U.S. Reclamation Service which has caused hard feelings in the region for the past 109 years. Rudolph Hering played a role in this project. He has been portrayed many times in this blog including two days ago when we celebrated the anniversary of his birth.
