Puerto Vallarta, Jalisco, June 27, 2026 – SEAPAL crews cleared a sewage blockage on Avenida Francisco Medina Ascencio after a traffic cone lodged inside the sanitary drainage line near Politécnico Nacional, causing wastewater to spill onto the roadway.
The blockage was reported on Thursday, June 25, along one of Puerto Vallarta’s busiest traffic corridors. SEAPAL attributed the obstruction to a cone from a nearby construction area that entered a manhole and stopped the normal flow of wastewater.
Crews used desilting work to remove the object, clean the affected area, and restore the drainage system. No long-term closure or broader service interruption had been reported by Saturday morning.
A small object with a big result
One plastic cone inside a manhole was enough to turn a drainage line into a street-level sanitation problem.
The spill did not come from a reported pipe collapse. It came from a solid object blocking a system designed to move wastewater, not construction debris, trash, plastic, storm runoff, grease, or oils.
That distinction is useful because Puerto Vallarta has spent much of June dealing with pressure on its water and sewer systems, from drainage strain after early rains to night sewer work planned in the Zona Romántica.
What SEAPAL wants kept out of the drain
SEAPAL’s public guidance is blunt — the drainage system is not trash. The agency warns that objects such as grease, plastics, bags, sanitary products, clothing, toys, and other solid materials can block the sewer network, leading to odors, stagnant wastewater, and costly repairs.
The agency also warns against directing rainwater into the sanitary drainage system. Its guidance states that sanitary lines are designed for wastewater, not stormwater, and that added rain flow can overwhelm the system.
SEAPAL has been pushing the same point with food-service operators in high-use zones. Earlier this month, the agency said sewer maintenance in Emiliano Zapata would include desilting and grease-trap checks, following recurring blockages caused by grease buildup and stormwater entering sanitary lines.
Why this location draws attention
Medina Ascencio carries traffic from the airport, Marina Vallarta, the Hotel Zone, and central Puerto Vallarta, so even short utility incidents can create public health concerns and slow movement.
The intersection with Politécnico Nacional is also in an area with heavy vehicle traffic and nearby commercial activity. That makes prevention more than a housekeeping issue. A single open or misused manhole can quickly affect drivers, pedestrians, workers, and nearby properties.
Puerto Vallarta’s drainage system already faces extra strain during the rainy season. Keeping solid objects and stormwater out of sanitary lines is one of the cheapest ways to prevent the next wastewater spill.
