General Guidelines and Conditions For Extraction of Sand and Gravel in Sarawak

Riverine / Upstream Areas

Generally DID would have no objection to the extraction of sand or gravel from the upstream areas, provided that there is no erosion problems at the river banks.
The extraction should be restricted to the middle third of the river only. Extraction should not be concentrated at a single area; it should be carried out evenly along the river bed.
There shall be no diversion, blockage and/or obstruction to the flow of water. Pollution in the river must be kept to the minimum and, if any, the contractor would be held responsible.

River Mouth Areas

Generally there is no objection to the extraction of sand from river mouth areas that are silted-up with sand bars for the beneficial effect of navigation and hydraulic discharge efficacy. However, these could also lead to bigger and stronger waves getting into the estuary as well as an increase in the penetration of the saline wedge up the river.
