Update on Sewage Operations and Conditions in Mexico as of Wednesday, January 8th

Jan 08, 2020 05:50PM ● By Paul Spear


As of this writing PB 1A/ 1B has one set of pumps in operation.  Mexico has also installed another set of motors.  They are currently testing them for proper operation.  The second set of pumps have not been placed in operation yet.  CILA has informed the IBWC that CESPT is still working to restore full pumping operations at PB 1A/1B. 


The SBIWTP continues to handle all flows contained in the main collection sewage pipe and all canyon collectors are in service.  No sewage is currently spilling due to a lack of pumping or treatment capacity.

The Tijuana River continues to flow at a rate of about 1.86 CMS or 1860 L/S.  This is beyond the capacity of PB Cila (1000 L/S).  PB Cila is not currently in operation.  The flow in the river is a mixture of rain run-off, treated wastewater and sewage. CILA has indicated that approximately 5 MGD is escaping the collection system at this time.  This has been ongoing since the rain event on 11/28/2019.  They indicated CESPT is addressing the problem.

Any further pertinent information will be provided in a future update.
