Currently the water that Liouguei District residents use is mainly provided by the Liouguei clean water facility and some mountain spring water. The water that the Liouguie clean water facility uses is drawn from a large well supplied by the Laonong River. During the flood season, water turbidity in Laonong River increases exponentially and cannot be adequately filtered to provide clean water to the residents at the Liouguei District. Therefore, water turbidity in well NO.6 should be first addressed to prevent disruption of water supply during the flood season. The proposed solution is to develop well NO.7 which will have the following features: (1) Increasing infiltration coefficient by adding additional water infiltration filters. (2) Protecting water during flood season. (3) Using mesh to protect infiltration filters and creating reservoir for water collection. (4) Increasing flooding volume using vertical permeable columns. (5) Increasing water collection rate using water reservoirs. Well NO.6 uses the traditional water pipes to collect water, but well NO.7 uses filter walls. By comparing the performance of the two wells, data shows that in normal season, well NO.6 reduces turbidity from 49 NTU to 48 NTU versus well NO.7 reducing turbidity from 24 NTU to 1.5 NTU. During the flood season, well NO.6 reduces turbidity from 250 NTU to 248 NTU versus well NO.7 reducing turbidity from 250 NTU to 15 NTU. Date clearly demonstrates the higher performance of using filter walls to reduce water turbidity and can help ensure continuous water supply during the flood season.
