Sewer Spill Statistics
In the later 1990s and early 2000s, the City of San Diego had a major increase in sewage spills. In fact, in 2000 there were 365 sewer spills, an average of one per day. This was due in large part because the City's aging sewer infrastructure was in need of replacement, repair and upgrades. Some pipelines had been in operation for a hundred years.
Beginning in 2007, the City sewer rates were increased to operate, maintain, repair and upgrade the City's wastewater system. The rate increases are paying for more than $585 million of necessary sewer system upgrades. These projects include replacement of sewer mains, sewer pipeline rehabilitation and sewer pump station improvements.
These system improvements have made a big difference. The Public Utilities Department keeps track of the number of sewage spills that occur in the City. The statistics below show a dramatic decrease in spills over the years.
