B. INSTALLATION OF BOOSTER PUMP AND FLOATING PIPE AS SUPPORT OF THE DREDGERS This method is used in order to support sediment flow from zone 1 near intake to spoilbank area with distance 1500-2000 m at 18 m height. Specifications of existing dredger with type Hydroland and Ellicot are only able to drain sediment optimally at a distance of +500 m with a capacity of + 70-100 m3 / h, so that additional booster is needed, while the previous pipeline using iron pipe and PVC pipe will be replaced by using HDPE floating pipe to be more efficient because of the cheaper material price than the iron pipe and more flexible by using a combination of rubber pipe. 310
