"I'm afraid that infrastructure budgets, especially for sewage treatment -- an issue that doesn't get much attention -- could be left out," said Chen Yao-jen (
A vote winning strategy?
It was, in fact, not until it became an issue during the past presidential election that many people in Taiwan learned that just 3 percent of domestic-use waste water goes through integrated sewage systems before being discharged into open water sources.
The low rate of treatment in Taiwan had once been pointed out by recently-resigned Academia Sinica President Lee Yuan-tseh (李遠哲), who reportedly called it a "shame in the international community," given that it is a developed country with a GDP of nearly US$13,000.
During the campaign, the KMT's presidential candidate, Lien Chan (
However, this problem created an excellent stage which the DPP's Chen has used to show off his achievements in dealing with the sewage problem.
In Taiwan, the highest level of integrated sewage systems for domestic waste water is Taipei City's 43 percent, achieved while Chen was mayor.
This rate is far ahead of other local governments, where septic tank systems are still commonly used by households.
For his efforts in raising the level of waste water treatment for Taipei, Chen gained a good reputation for establishing infrastructure to deal with the situation.
However, few people are aware that in Taoyuan, headed by Chen's Vice President-elect Annette Lu (
So who needs treatment?
Taoyuan is typical of rural areas where septic tank sewage systems are still common.
Even in industrialized Kaohisung City, the sewage treatment rate is only 11 percent.
It was only in July 1994 that the Construction and Planning Administration under the Ministry of the Interior (MOI) issued guidelines for sewage handling in new communities that accommodate more than 500 residents.
However, the government appears unable to deal with overcrowded cities.
Environmental engineers have said for a number of years that sewage treatment levels in rural counties are incredibly low, making it impossible to make efforts to clean up polluted rivers ineffective.
Engineers said that domestic waste water should not be drained along with rain water and transferred to sewage plants for further treatment before discharging directly into rivers, as is currently done.
"Once sewage treatment facilities are established, we can treat household waste water and rain water separately," said Wen Ching-gung (溫清光), an environmental engineering professor at National Cheng Kung University (成功大學), saying that rain water is far cleaner than household waste water.
A comparison with developing countries
Industry experts say the government has ignored the issue of establishing proper sewage treatment -- an index of life quality -- for decades.
"Even in developing countries, such as China, cities with more than 300,000 residents are required to build sewage treatment systems," said James Huang (
China is now reportedly making efforts to increase sewage treatment levels in its cities.
According to China's Xinhua News Agency, the World Bank and the Chinese State Development Bank will provide 65 percent of the US$310 million in loans for a project in Chongqing, for which the city government is to raise the rest of the money.
"Based on our experience in China, leaders have admitted that pollution levels in lakes and rivers constitute an environmental crisis. That's why they have to do something as soon as possible," Huang said.
"Although I'm optimistic about Taiwan's new government, it doesn't mean that we can count on political figures," Huang said.
"Such people tend to do things which can draw people's attention in a short period of time," he added.
Looking at the big picture
Industrial engineers, meanwhile, suggest that the new government should consider actively cleaning polluted rivers, instead of just focusing on local sewage treatment levels.
"The high sewage treatment rate in Taipei City cannot [lead to the] immediate cleaning of the Tamshui River (淡水河) because more pollution controls are needed in its upper reaches," said CTCI's Chen, adding that low sewage treatment rates in Taipei County and Taoyuan County have resulted in heavy pollution.
"We need more measures to form a complete set of water treatment policies," Chen said.
NO HUMAN ERROR: After the incident, the Coast Guard Administration said it would obtain uncrewed aerial vehicles and vessels to boost its detection capacity Authorities would improve border control to prevent unlawful entry into Taiwan’s waters and safeguard national security, the Mainland Affairs Council (MAC) said yesterday after a Chinese man reached the nation’s coast on an inflatable boat, saying he “defected to freedom.” The man was found on a rubber boat when he was about to set foot on Taiwan at the estuary of Houkeng River (後坑溪) near Taiping Borough (太平) in New Taipei City’s Linkou District (林口), authorities said. The Coast Guard Administration’s (CGA) northern branch said it received a report at 6:30am yesterday morning from the New Taipei City Fire Department about a

BRP Teresa Magbanua “was compelled to return to port” from Sabina Shoal (Xianbin Shoal, 仙濱暗沙) due to bad weather, depleted supplies and the need to evacuate personnel requiring medical care, the Philippine Coast Guard (PCG) spokesman Jay Tarriela said yesterday in a post on X. The Philippine vessel “will be in tiptop shape to resume her mission” after it has been resupplied and repaired, Philippine Executive Secretary Lucas Bersamin, who heads the nation’s maritime council, said
REGIONAL STABILITY: Taipei thanked the Biden administration for authorizing its 16th sale of military goods and services to uphold Taiwan’s defense and safety The US Department of State has approved the sale of US$228 million of military goods and services to Taiwan, the US Department of Defense said on Monday. The state department “made a determination approving a possible Foreign Military Sale” to the Taipei Economic and Cultural Representative Office in the US for “return, repair and reshipment of spare parts and related equipment,” the defense department’s Defense Security Cooperation Agency said in a news release. Taiwan had requested the purchase of items and services which include the “return, repair and reshipment of classified and unclassified spare parts for aircraft and related equipment; US Government
More than 500 people on Saturday marched in New York in support of Taiwan’s entry to the UN, significantly more people than previous years. The march, coinciding with the ongoing 79th session of the UN General Assembly, comes close on the heels of growing international discourse regarding the meaning of UN Resolution 2758. Resolution 2758, adopted by the UN General Assembly in 1971, recognizes the People’s Republic of China (PRC) as the “only lawful representative of China.” It resulted in the Republic of China (ROC) losing its seat at the UN to the PRC. Taiwan has since been excluded from
