Big projects aimed at stemming the toxic sewage flowing from Tijuana into Imperial Beach and the surrounding region are on the horizon and that’s a welcome development. But any such improvements come with a nagging question based on historical experience: How long will this fix last?

Some did, and they greatly diminished the health and environmental threat — and reduced beach closures.
