<p align="justify">HAS Hanandjoeddin Airport is located in Tanjung Pandan, Bangka Belitung Islands, Indonesia. Rainwater treatment design is required for Hanandjoeddin HAS Airport to operate optimally. The designs include designing the layout and geometry of Rainwater Harvesting System, Bioretension, Long Storage, and Conventional Drainage Channel as well as the construction cost and feasibility analysis. The Design of Rainwater Harvesting System resulting a water tank with a length of 40 meters, width of 5 meters, and height of 1 meter. The cost required to make the Rainwater Harvesting tank is Rp.247.654.858. Bioretention design is resulting a Bioretention area of 300 m2 with a depth of 1 meter. The Cost required to construct the Bioretetion is Rp. 280.109.000. In the design of Long Storage, obtained 4 types of cross sections used with the cost required to construct is Rp. 4.244.873.542. In Conventional drainage design, obtained 6 types of channel cross section used with the cost required to construct is Rp. 7.459.696.866. Based on the economic analysis of the operation of the Rainwater Harvesting System with an Initial Rate of Return of 12%, the Breakevent Point happened in 5 years 6 months of operation. <p align="justify">
