MONITORING OF CONSTRUCTION ACTIVITIES AFFECTING DRAINAGE MAINS
of catch basins, grated manholes, and side inlets along highways/streets
are construction debris and silt carried by water discharge from
construction sites. Not only are the streets inundated during
construction operations but the silt and debris impede the flow of the
natural run-off during heavy down-pour causing flooding over wide areas.
In order to minimize if not prevent flooding along highways and local
streets it is directed that in the issuance of Building Permits the
following conditions shall be attached:
1. The contractor or in-charge of construction shall provide a
sump/silt chamber or debris trap within the construction site to
contain the water with silt and debris before discharging to the
existing catch basin or site inlet.2. Water from construction site including local run-off shall
be discharged at or near a catch basin or side inlet and not on road
pavements, street curbs, and gutters.3. The contractor or in-charge of construction shall have the
catch basin or side inlet checked before and after the day’s work for
any silt or debris that might still have come from the construction site
and have the same removed.4. Damages to private and public properties/utilities due to
flooding from construction work shall be the sole responsibility of the
contractor.
Construction activities shall be monitored from time to time to
ensure that the conditions are complied with. Violation of the
conditions shall be grounds for the revocation of the permit.
For compliance.
