Kiri washing station was build in 1997. Today, 1.200 farmers from the surroundings villages Gitumbi, Kirunyuini, Kerere and Kaboia aredelivering their cherries. The area experiences a biennial production cycle with the early harvest being from April-June and the late second season being from October-December. The main varieties of coffee grown are SL28, 34 and Ruiru 11. In line with the rising awareness on the need to conserve the environment, the washing station has dug the waste water soak pits away from the water source where the waste water is allowed to soak in back to the soil.
