The lakes and rivers serve as an important lifeline for the Wajahe civilization. Running water cannot be disrupted or tainted with filth, and people should not drink this tainted water - fines are placed upon one who urinates or defecates into running water that is not specifically designated for such a purpose (as is common in the south-east, where the prevalence of wetlands somewhat mitigates this issue). Likewise, progression in the alchemical beliefs spurred by the slow rediscovery of Riverine manuscripts has created the need for the exotic form of urine-bleaching, and that the remains of animal and human waste can increase the virility of the soil, after being appropriately treated to avoid increased attraction of pests. The Wajahe have developed a public system, through the employment and creation of public restrooms in city centers, which will collect Urine to be bought by Industries at a subsidized rate, primarily fiber-workers and dyers, who benefit from the hastened and successful form of bleaching. This system is based heavily on that of the city of Koshayis, the progenitor of this innovation.
