We have multiple plastics from water source to sewage plant.

PVC, HDPE, PVC, PEX, and then on down the drain to ABS, PVC, and back to HDPE.

The main sewer that now drains our city is some impressive HDPE pipe, corrugated on the outside, smooth on the inside.

Our sewage is reprocessed into near-potable water which is sent out in purple PVC pipes for irrigation, and potable water that goes out on PVC and HDPE pipes.

My wife's family home gets water from a Sierra river. It's pumped from a river well to a big HDPE water tank through PVC piping. Waste water flows to a big plastic septic tank and a plastic pipe leach field.

Every human being on earth deserves something similar.
