Inigasi network can be easily damaged due to rains / water, sting rays and solar heat indirectly, animals / humans, wild plants, or because of the design and construction of facilities and the network is not good, so that:
- The hot sun will cause a rift which facilitates body eroded channels;
- Heavy rains will hit and hit the body of the building so easily eroded or eroded;
- Flowing water exceeds the speed plan, will erode the body of the channel so that the process of scour and erosion will occur very easily;
- The existence of wild animals were released around the buildings and facilities will be able menusak inigasi the facility if it is not handled well,
