After Chi Shao woke up, everyone in the Vine Tribe heaved a sigh of relief, and bright smiles reappeared on their faces.
Because the weather this year has been quite good, the crops have grown lush, and the various wild beasts and birds have reproduced quickly.
Just needing to breed a few more generations, these wild beasts and birds will eventually be slowly dosticated into real poultry and livestock.
On the eastern bank of the Feiyu River, most of the workshops have gradually relocated, and even the breeding areas have moved to the eastern bank, as Jiang Xuan wants to preemptively prevent any diseases that might be spread by the dosticated animals.
However, with this change, an obvious problem has arisen.
And that is sewage.
Whether it’s slting bronze, tanning beast hide clothing, refining salt, or making pottery, all these activities produce a large amount of sewage.
When the tribe was small, these workshops were also small and relatively scattered, so the sewage wasn’t particularly noticeable.
Now, as the Vine Tribe has grown larger, the workshops have also expanded, producing more and more sewage.
Moreover, since the sewage from the workshops is almost discharged arbitrarily, a lot of land has been polluted, and a foul stench can be slled from afar.
"Things can’t go on like this. If the random discharge continues, one day, the Feiyu River will turn into a stinking ditch, and we’ll have to fetch drinking water from sowhere else."
Jiang Xuan walked through the primitive industrial area on the eastern bank, looking at the polluted soil and slling the various pungent odors, feeling very uncomfortable.
Cang Er, the leader of the Guard Team at the second settlent, carefully asked beside him, "Chief, is it really that serious?"
The tribe’s people had never seen what real industrial pollution looked like, nor were they very concerned about sewage, thinking it wasn’t a big deal.
Previously, Cang Er also thought the sa. Although the stench was bad, it didn’t seem to matter much.
"If the random discharge continues, the situation will be ten tis, a hundred tis worse than I said!"
Knowing Cang Er didn’t believe him, Jiang Xuan had a Guard Team Warrior catch a few shrimps from the riverbank.
The shrimps and crabs beside the Feiyu River were abundant, and the warrior quickly returned with a few large shrimps.
"Watch closely."
Jiang Xuan threw the shrimps into a drainage ditch outside a clothing workshop.
The soil in this drainage ditch had turned black, and the sewage was horribly slly. The large shrimps, which were very sensitive to water quality, desperately crawled out as soon as they got in.
Jiang Xuan used a stick to push them back into the water, and they continued to crawl out.
"See that? This kind of water can’t even keep shrimps alive. If you put a fish in that can’t crawl, it won’t take long before it dies."
"Think carefully, if one day, the river is full of this kind of sewage, all the fish, shrimps, crabs, and even the Water Scorpions that can beco giant dragonflies will either die or flee this area."
"Our crops will also fail to grow tall, or big, or even dry up and die."
"What would we do then?"
Jiang Xuan’s words finally made Cang Er and the others take the issue seriously. Just imagining such a terrifying scenario made their scalps tingle.
"Chief, what should we do then?" Cang Er looked at Jiang Xuan, knowing that he must have a solution.
"What should we do? Of course, we need to treat the sewage."
Jiang Xuan pointed to all the workshops, including the breeding area: "Every place that produces sewage must have a unified drainage pipe laid, centralized treatnt of the sewage before it is discharged into the river."
"Chief, what is a drainage pipe?"
"A drainage pipe, of course, is a conduit that can drain water. We can fire ceramic drainage pipes and then bury them underground, covering them with soil, so the areas where sewage flows won’t be reeking with stench or pollute much land."
After hearing Jiang Xuan’s words, Cang Er nodded in realization. He had seen the tribe use bamboo to fetch water from afar, so he figured the drainage pipe should be similar in shape to hollow bamboo.
"Then what happens after the sewage is collected?"
"Then it has to be filtered and purified."
Cang Er scratched his head, not quite understanding what "filtering" and "purifying" ant, but he didn’t ask further, knowing he’d find out eventually.
Jiang Xuan first chose a relatively low-lying area to build a sewage treatnt plant.
Then he went to the pottery workshop and molded a clay prototype of the round pipe.
This round pipe had an outer edge on one end and an inner edge on the other. By combining the outer and inner edges, two pipes could be connected together.
It was a bit like a ceramic chimney but much larger and more solid.
Nowadays, the pottery workshop was not just two cross-ventilated kilns but was as tall as two houses, capable of firing many large ceramics at once.
After Jiang Xuan made the first round pipe prototype, he explained the pipe’s function and thod of connection to the artisans.
It wasn’t complicated, and with a prototype as a sample, the artisans understood imdiately.
"Rest assured, Chief, we will try our best to fire enough pipes."
Jiang Xuan nodded and said, "Everyone, please work hard. Sewage treatnt is very important for all of us, and future tribesn will always be grateful to you."
After Jiang Xuan’s words, the artisans imdiately felt a sense of mission and worked with increased enthusiasm.
