What in the world would I need to drain another 40L / 8 gallons into?
*It's pointed out a few times that only a few of the plants are local native species, many aren't North American at all.
For example, what if water wasn't billed at a flat rate? Each building could have an allotment based on size and expected occupancy. One rate within that amount, and a higher rate for each unit over it. Calculate the level such that essential water usage is affordable and watering a large lawn becomes a luxury.
I doubt that exact plan is workable without further elaboration; the law of unintended consequences is powerful. But the point is that "we should have more sustainable landscaping" doesn't necessarily equate directly to "ban all grass".
I replaced it with a washer that uses less than a third of that. The kids would generate a 5 loads of laundry per week, and my suggestions that we use less were... not well received.
The other fixtures here are very nicely maintained, a great landlord, but the plumbing is 40 years old. While it's no longer possible to purchase a toliet that uses four gallons per flush, they are still everywhere.
Legislation? Tighter ordinances? Good luck getting those passed, or enforced. And however necessary, the replacement of antiquated plumbing appliances amount to extremely regressive taxation: those with the least money would bear most of the financial cost.
