Abstract

A raw water storage reservoir was constructed with earth embankments and a soil blanket floor lining. Treated sewage effluent was used as construction water. Bacteria in the soil were capable of converting the organic nitrogen and ammonia present in the effluent to nitrite and then to nitrate under aerobic conditions. This nitrate was reduced to nitrogen gas under anaerobic conditions. The generation of gas had a "leavening" effect on the soil structure of the floor lining leading to a high water permeability, thus making the soil lining ineffective.

The Failure of a Soil Blanket Lining Caused by the Action of Bacteria

A raw water storage reservoir was constructed with earth embankments and a soil blanket floor lining. Treated sewage effluent was used as construction water. Bacteria in the soil were capable of converting the organic nitrogen and ammonia present in the effluent to nitrite and then to nitrate under aerobic conditions. This nitrate was reduced to nitrogen gas under anaerobic conditions. The generation of gas had a "leavening" effect on the soil structure of the floor lining leading to a high water permeability, thus making the soil lining ineffective.
