A safari lodge in Kenya has found a unique way to put its waste water to good use for the local ecosystem. Way back in the 1980s, Serena Hotels built a lagoon consisting of six chambers at their Amboseli Serena Safari Lodge. The Lodge is connected to the lagoon through an array of septic tanks and a drainage system, bringing the wastewater from the kitchen, bathrooms and laundry directly into the chambers. Through a process of aeration, oxygenation and sunlight exposure, the water travels through each of the six chambers and undergoes a natural cleaning process.
