Wittybb sent me this article: 黎廣德﹕淨化維港 加速發展 決心何在？
I too don't understand why Hong Kong Government is dragging its feet in wastewater treatment. Despite a large surplus in the budget, Phase 2B of the wastewater treatment plan won't be reviewed till 2010? Secondary treatment (activated sludge or other biological processes) is a must and should have been implemented along with the primary treatment (physical/chemical processes). If the government is serious about cleaning up the Victoria Harbor, it should build a treatment plant that is up to the US standards.

Politics? Lack of pressure from the pubic to drive it?
How much environmental friendly education do we the public have gotten in HK since 2000?
If I recall correctly from the boat tour, the city of Chicago took care of the city's sewage system (via the canal) and discharged into the lake Michigan. Interestingly, the water supply also comes from the lake. I think the HKSAR government should take leadership in certain 'projects' and take care of some environmental issues serious (provided that these projects do not impact other citizens' quality of life).

politicians in HK just use the environment as a campaigning tool coz no one would oppose to the idea (unlike the US).
Wastewater from Chicago normally would not go into Lake Michigan (or only a small quantity does due to lock leakage and density current in the Chicago River). The Chicago Sanitary and Ship Canal diverts the Chicago River (along with the treated sewage) to the Des Plaines River. Chicago has this tunnel project (TARP) where BIG huge underground tunnels were built to store wastewater during and after a rainstorm. The problem with Chicago is that part of the city (downtown and surrounding areas) is still using combined sewer, meaning rainwater will mix with sanitary sewage and all get sent to the wastewater treatment plant. Before the tunnels were built, the treatment plant simply could not handle that much water after a big storm. So some of the untreated sewage would end up in the Chicago River. The combined sewer overflow seldom happens any more.
