Description
The Water Purification Station occupies a shaded platform near the settlement's main cisterns, its position chosen to allow gravity-fed flow from storage to filtration and back to clean-water vessels. The heart of the facility consists of six large clay vessels, each standing four feet tall and two feet in diameter, arranged in two parallel rows of three. These vessels are the product of the settlement's finest potters, their thick walls fired to exceptional hardness and their interiors glazed smooth to prevent any contamination from the clay itself. Each vessel is mounted on a sturdy wooden frame that elevates it three feet above the platform floor, allowing filtered water to drain into collection containers positioned beneath.
The filtration medium within each vessel follows a precise layering system developed through generations of Vaitafe water knowledge. The bottom layer consists of large pieces of clean coral rubble, creating drainage channels that allow filtered water to flow freely toward the outlet. Above this lies a thick layer of coarse sand, followed by progressively finer sand that removes smaller and smaller particles. The crucial middle layer contains crushed charcoal made from coconut shells, which absorbs impurities, removes unpleasant tastes, and neutralizes many harmful substances. The topmost layer is fine white sand that catches any remaining particles and gives the filtered water exceptional clarity.
Water enters each filtration vessel through a carved wooden channel fitted with a woven fiber screen that removes leaves, insects, and larger debris before the water even reaches the sand. The flow rate is carefully controlled by adjustable wooden gates that can be opened or closed to regulate how quickly water passes through the system. Slower filtration produces cleaner water, so the gates are typically set to allow only a gentle trickle during normal operations. During emergencies when large quantities of water must be processed quickly, the gates can be opened wider, though the resulting water may require a second pass through the system.
The filtered water emerges from spouts at the bottom of each vessel, crystal clear and free of the slight cloudiness that sometimes affects cistern water. This purified water flows into dedicated storage vessels marked with carved symbols indicating their contents have been filtered. These vessels are reserved exclusively for drinking water and are never used for cooking, washing, or other purposes that might introduce contamination. A dedicated water purifier tends the station, replacing filtration media when it becomes clogged, cleaning the vessels between batches, and maintaining detailed records of water quality using a series of standardized tests involving clarity, taste, and smell. The charcoal layer requires replacement most frequently, approximately every two weeks under normal use, while the sand layers can function for several months before requiring renewal.
Benefits
The Water Purification Station generates 2 Prestige, demonstrating the settlement's commitment to health and their sophisticated understanding of water treatment. The facility can process up to 300 gallons of water per day, providing the entire settlement with access to exceptionally pure drinking water. Characters who drink exclusively from the purified water supply gain a +2 bonus on Fortitude saves against waterborne diseases and food poisoning. The purification process also extends the safe storage life of water by removing organic matter that would otherwise promote bacterial growth, allowing purified water to remain potable for up to twice as long as untreated cistern water.
