Reliability of low pressure waterworks with earthen dams

Reliability problems for low pressure waterworks are considered. Earthen dams with long operational periods are shown to have substantial damage and are in unsatisfactory condition.Their condition should be monitored and investigated. It is important to take steps on their repair in due time. To make their operation more reliable use of large-porous hard low-cement concrete is recommended.The structure of earthen overflow dam with the slope fixed be geosynthetic shells is given.
