OCEANSIDE — Sewer blockage near the intersection of Mesa Drive and El Camino Real caused a spill on Monday afternoon, and a road closure on Mesa Drive in both directions as city crews responded.
Crews worked through the night to contain and divert the flow to a nearby sewer.
Mesa Drive remained closed between Mainsail Road and El Camino Real on Tuesday.
A city sewer crew continued mopping up after approximately 150,000 gallons of wastewater overflowed into the nearby Loma Alta Creek and slough on Monday.
Sewage discharge is being contained, and treated at La Salina Wastewater Treatment Plant.
The slough is closed off to the ocean while repairs and cleanup are underway. Discharge did not reach the beach.
The crew is also investigating the cause of the blockage that led to the sewer discharge. There is no word on how long repairs may take.
