| Abstract: |
| A rainwater utilization project is designed for a residential section of Guilin to use rainwater to meet the requirement of road cleaning, car washing and plant irrigation. The residential section is 404404 m2,with 111610 m2 of total area of buildings,62% of area with plants and grasses,10% of road area. The process flow is as follows:rainwater→sedimentation tank→quarts sands filter→cistern. Two cistern,which cubage was 7×103 m3 The cost-effective analysis indicates that the static capital pay off time is 8.05a. The 1.696×105 m3 of tap water can be saved in a year. |
