Improved Rainwater Harvesting and Sanitation Systems
When the indoor toilet was invented, it changed the game. Yet when sewers were finally made in places like London, you no longer saw people dump out their “waste” collection onto the street below. Rather, the sewer handled a lot of this for them. Sanitation has been heavily improved but it’ll become even better. Things such as sewer batch plants will be able to improve drainage and sewer systems entirely. On top of this, things like rainwater will still end up in other water sources. Yet on land, we’ll be able to harvest that rainwater and purify it into proper drinking water. If rainwater collects in a sewer, rather than dumb it out into an ocean, we’ll harvest it for use in the city. Thus allowing has to have properly purified tap water.
