Why doesn the City build a stormwater treatment facility?
The City has determined that building stormwater treatment facilities is not a cost effective solution due to the large number of the facilities required to treat the stormwater flow generated on a seasonal basis. Instead, smaller multi-purpose regional projects placed in various strategic locations within the city have been recommended for implementation, such as those funded by Prop. O. These types of projects will mitigate many of the pollutant concerns in stormwater generated runoff.
Such a facility would be extremely costly to build and maintain. And, the massive amount of water coming through the facility during a rainstorm would easily overwhelm the system. As with virtually every pollution issue, it is far cheaper to control the problem at the source as opposed to treating it later on.
