The Spill at a Glance

Days: 31

Amount: Daily, an estimated 180 million gallons of partly treated sewage.

Cumulative: As of Tuesday, in excess of 5.58 billion gallons.

Tijuana spill: A pumping station that diverts Tijuana sewage to the Point Loma treatment plant was turned back on last week, but shut down again Tuesday. The station can handle only 13 million gallons a day of raw sewage from Tijuana, but raw sewage mixed with contaminated rain runoff pushed Tuesday’s flow to more than 111 million gallons. Coastline closed: 19 1/2 miles: from the mouth of the Tijuana River, near the international border, to the North Island Naval Air Station in Coronado, and from the mouth of the San Diego River in Ocean Beach to Point Loma. Small stretches of Mission Beach and Mission Bay are also closed.

Status of repairs: A deadline of April 4 for completion of repairs has been set. Despite several rain delays, city officials are hopeful of sticking to the deadline. Recent efforts recovered several sections of pipe about a mile from shore that bear large scrapes, fueling speculation that a passing ship may have damaged the outfall pipe. Workers also found an unexplained deep gouge on a section of pipe they picked up three-quarters of a mile from shore. Officials said the 100-foot-by-300-foot repair barge remained docked at Navy property in Point Loma on Tuesday. City officials plan to announce today their choice of an independent forensic consultant, who will determine the cause of the rupture.

Pipeline repair cost estimate: $10 million.
