City to spend $7 million to shore up two sewage pump stations that failed during September 2011 blackout
City to install seven backup generators at the two pump stations that sent 3.4 million gallons of sewage during massive outage
On March 4 San Diego city councilmembers agreed to pay a $600,000 fine for a massive sewage dump from two pump stations during the September 2011 blackout.
Now, the City is shelling out an additional $6,795,534; this time to install seven diesel emergency generators purchased for nearly $11 million in May 2012.
By installing the seven backup generators, the City hopes to avoid another massive spill like the one that sent 3.4 million gallons of sewage from two pump stations in Sorrento Valley and South Bay. The pumps depended on electricity from two SDG&E substations. The power outage shutdown the stations for anywhere between 4 to 12 hours.
"...the Department had to consider the probability of losing both electrical feeds due to an extended power outage, earthquake, fire or other incident that could take out multiple substations or the power lines coining into the stations. Although the probability of losing both electrical feeds is still quite low, depending on the length of the power outage, the consequences from a spill could be very high given the amount of flow that is processed through these facilities," reads a staff report.
The permanent installations are expected to be complete by the end of 2014.
