Count on Me for Smooth Flowing Water!

Due to the low topographic profile of Taipei, the city is prone to frequent floods. As a result, the flood prevention personnel of the city are well trained, highly mobile and quick to react to contingencies. These personnel are just like a powerful squad of logistical troops that have been trained just to be able to serve residents in times of emergency. Apart from offering excellent flood protection for Taipei, they have also been dispatched to assist other cities and counties. Thanks to these experts, Taipei is well prepared and ready for information gathering, resource organization and disaster prevention.

Treating Drills and Exercises as Real Disasters: An Effective System of Flood Prevention and Emergency Response

In order to protect the safety of our residents' lives and property and also maintain public facilities of flood prevention, storm sewers,HEO (the Hydraulic Engineering Office) has specifically established the "Guidelines for Flood Prevention and Emergency Response" , which clearly outlines the establishment of the "Flood Prevention Duty Roster" , "Typhoon & Torrential Rain Monitoring Crew" and "Flood Prevention and Emergency Response Crew" , providing details of comprehensive structures, shifts, responsibilities and duties. The total number of personnel needed in this system comes close to a thousand, with the mayor as the chief commander. The guideline is used as the protocol in emergencies in order to achieve the highest efficiency in task completion.

Public Participation to Strengthen Emergency Response

There will always be a missing element in flood prevention construction no matter how much effort has been made.
Under normal circumstances without sedimentation and malfunctioning, the maximum discharge capacity of storm sewers is 78.8 mm per hour; once the intensity of rainfall exceeds this design value, water will begin to buildup.
In order to be fully prepared in times of floods, Taipei City Government has established an effective mobile dispatch system. Apart from integrating all the water pumping units available across each agency, the government has also issued open contracts for contractors who are sincere about public welfare. As soon as an official typhoon warning is issued, these contractors are able to mobilize a crew of 92 workers, 28 construction vehicles and 108 types of machines on demand to standby at areas that are prone to flood.
A win-win situation is only possible if the government and the public work hand in hand.

Meticulous Preparation and Drills with No Room for Mistakes

In every year, there will be a low water period that lasts for 5 months. During this period, the maintenance personnel of HEO are required to complete a two-stage comprehensive inspection and maintenance of embankments, pumping stations, evacuation exits, gates and valves. During the flood prevention period (beginning from May to November), water pumping stations and relevant facilities need to undergo intensive test runs in order for the operating personnel to be familiar with the operations, maintenance and repairs of the pumps and generators. In addition, this is also to ensure that the machines are capable of normal operation at any time to accomplish their missions. Furthermore, a fleet of 5 vehicles with various rescue capabilities, along with 49 mobile water pumping machines, 15 generators have been ready for use at any time.

Displaying More Courage in the Face of Storms

When a typhoon warning or heavy rain warning is issued, all personnel of relevant government agencies and the maintenance crew of HEO are required to standby immediately. While residents are advised to return to their homes for their safety, these brave personnel go against these warnings of safety and return to their posts, placing themselves in great danger to do their part to minimize disaster damage. The responsibilities of these personnel grow larger as the weather conditions deteriorate, and endless disaster recovery, emergency rescue and repair work awaits them. Every typhoon is a severe test for these personnel, and their mobilization abilities and capabilities in emergency reaction have been reinforced time and again after experiencing many typhoons, ensuring the safety of our residents' lives and property.

24-Hour Nonstop Operation at Water Pumping Stations, the Hardship of Standby All Day Long

Once a typhoon land warning has been issued, HEO will immediately summon about 700 personnel of relevant crews back to each water pumping station to perform their duties, carry out machinery tests, patrol various areas in the rain, supply mobile support and provide sandbags to each District Office.
All personnel at water pumping stations are to report to their designated posts and keep a close eye on the flood situation in preparation to start the pumps once the order is given. The most frightening part about their work is to go outdoors to clear away debris brought by the flood waters. Carelessness in any part of their work may result in danger to their own lives and failure to pump out water, causing severe damage.
Not only that, the timing of activation/deactivation of water pumps is also critical to the safety of all Taipei residents. The operating personnel must be fully attentive and wait for the rivers' stage lower than ground level before reopening the valves for the water to drain naturally.
Apart from these hardworking personnel at the water pumping stations, the operators of the mobile water pumping machines are truly the saviors of low-lying areas as they perform their tasks under adverse weather conditions.

Flood Warning ,Rainfall and River Information Make Better Work

HEO has reorganized the radar images, satellite images from the Central Weather Bureau, with the data from the office's rainfall stations, river water level monitoring stations, stage gauge readings from sewers and water pumping stations and posted compiled information on its website for decision makers and relevant personnel to obtain the latest information during typhoons and heavy rains.

Instant Messaging and Presence Information One Number Calling Express (ONCE)

When a typhoon approaches, the "ONCE" information relay system notifies the relevant personnel to carry out their duties at designated locations. This feature also ensures that evacuation gate closure notices are early delivered to the neighborhood chiefs and the media ASAP to inform residents and vehicles adjacent to rivers to evacuate as soon as possible.
The "ONCE" featured extensible message and presence protocol is more efficient compared to the original telephone notification methods.
The broadcasting warning system of evacuation gate closure installed at the 7 evacuation gates (no.1, 3, and 5 of Tamsui River, no. 5, 6, and 9 of Keelung River and no.4 of Xindian River) proved to be very useful in alerting nearby residents and vehicles owners to evacuate at the earliest time.
