 system that would serve homes directly. As a solution, the city allowed "water carriers with jugs and horse-drawn wagons…to serve the city’s domestic [water] needs". It took until 1857 for the council to realize that the system needed to be updated, which led them to grant William G. Dryden franchise rights to provide homes with water through a system of underground water mains. The initial system served only a few homes using an unreliable network of wooden pipes. In December 1861, heavy rains destroyed the system and Dryden gave up his franchise. The city attempted contracting out water distribution rights to others, but none of the systems that resulted from these contracts was successful.

The city’s previous unsuccessful attempts to allow others to develop a water system on its behalf prompted the city council to relinquish its rights to the water in the Los Angeles River

, three already successful businessmen. This change was at the expense of the city of Los Angeles, which could no longer benefit from their municipal water distribution business. The three men created the Los Angeles City Water Company, which violated many of the provisions of its lease on the Los Angeles River, including secretly tunneling under the river to extract 150 times as much water as the lease allowed. As a result, as the end of the lease drew near in the mid-1890s, “popular support began to build for a return to complete municipal control of the local water supply”.

Public control

The leader in the fight to end private control of the water supply was Fred Eaton
Fred Eaton
Frederick Eaton , known as Fred Eaton, was a major individual in the transformation and expansion of Los Angeles in the latter 19th century through early 20th century, in California, United States...

. Eaton proposed that tax revenues would enable the city of Los Angeles to provide water to its residents without charging them for the use of water directly. Eaton’s views were especially powerful because of “his distinguished record of achievement rendered in both the private and public sector”. During Eaton’s nine-year term as the superintending engineer of the Los Angeles City Water Company, he headed a large expansion of the company’s water system. Eaton left his position in 1886 when he was elected City Engineer. In his new public position, Eaton devoted his time to the updating and expansion of the sewer

 system. Eaton felt that the Los Angeles City Water Company was not serving the citizens of Los Angeles in the best way possible because of high rates and the fact the company frequently paid dividends to its stockholders instead of improving the water system. In early 1897, city engineers began creating plans for an updated water system while the city council informed the Los Angeles City Water Company that its lease would not be renewed beyond its expiration date, July 21, 1898. In early 1898, the city began talks with the Los Angeles City Water Company about taking over the company’s current water system.

Throughout the negotiations, it became clear that it was necessary for the current senior employees of the Los Angeles City Water Company to keep their jobs in order to ensure that the water system could continue to operate. It was not guaranteed, however, that William Mulholland

, Eaton’s protégé and the man who took over the job of superintending engineer when Eaton was elected city engineer, would have a position working with the city-owned water system. Mulholland was not popular with city officials because he did not produce records that the city requested during negotiations. Near the end of the talks between the city and the water company, it was discovered that neither the requested records nor a map of the water system existed. Mulholland, who was supposed to be in charge of the non-existent records, was never a fan of paperwork and claimed that he had memorized all of the necessary information, including “the size of every inch of pipe and the age and location of every valve”. Mulholland secured a job with the city when he successfully demonstrated his ability to recall the information. Once Mulholland was assured a job with the city, he “promptly intervened with the company’s principal stockholder, advising him to accept the city’s offer of two million dollars for the system”.

Power delivery

The LADWP first offered municipal electricity in 1917 when the San Francisquito Power Plant began generating electricity. It ultimately produced 70.5 megawatts and is still in operation in 2004, producing 44.5 megawatts.
On January 17, 1994, the city of Los Angeles experienced its one and only total system black-out as a result of the Northridge earthquake

. Much of the power was restored within a few hours.

In September 2005, a DWP worker accidentally cut power lines that caused over half of Los Angeles to be without power for one and one-half hours.

The rolling blackouts in the summers of 2006 and 2007 were caused by extreme high temperatures. Because the components were up to 60 years old, the extreme temperatures melted the power transformers and insulators. As a result, LADWP has decided to upgrade the overhead power lines.

Power system

The LADWP currently maintains a generating capacity of 7,200 megawatts, in excess of the peak demand of 6,165 megawatts by the city of Los Angeles. It provides this surplus electricity to other utilities, selling 23 million megawatt-hours in 2003.

Because Los Angeles is older than most other cities in California, the LADWP is currently faced with several unique issues. Most of the power lines in Los Angeles were built above-ground before it became customary to run power lines below-ground; as a result, the horizon line of the typical Los Angeles boulevard looks much more cluttered than boulevards in most Southern California cities. Starting in 2007, LADWP has a long-term project to upgrade the overhead power lines and convert them to underground. This difficult conversion has been slowed by budget constraints, the impact on traffic, the pursuit of other modernization projects, and the lingering effects of a workforce reduction over the last decade. Budget issues are particularly acute in the department's transmission system, where underground transmission costs about 10 to 14 times the cost of overhead transmission, per unit length, and the technical and environmental challenges which confront such installations. Upgrading the overhead lines is expected to take 10 to 15 years. The upgrading of LADWP's overhead power lines consists of eliminating the V-shape brackets on the power poles that are holding up the crossarm and replacing them with cross-brackets that are put on the crossarm. Some of the wooden power poles are being replaced with metal poles.

The department recently completed two 230 kV underground projects using an innovative cable technology which does not utilize oil as an insulator. The oilless cable mitigates the environmental issues associated with oil-type cable.
