Solar-powered fluorescent strips light our passage; at intervals there are short water pipes, about the width of my arm: measuring equipment can be fitted to these, to check whether there is internal leaking.We turn left into a side room with bare concrete walls, ceiling and floor, and containing what looks like a squat oil barrel suspended on a metal frame, above a circular hole.“This is the most important part of the dam,” says Fan. A wire runs from the middle of the barrel down to an anchor point within the hole. The worst crisis occurred in 1963-64 when water was delivered only once every 4 days for 4 hours. It also pledges to provide “one of the safest water supplies in the world”.However, the city does not have a broader policy addressing its long-term water scarcity problem. Hong Kong news – Independent &, non-profit Civic Exchange and ADM Capital Foundation’s latest report, “Older Hong Kong residents will remember water shortages and rationing in the 1960s and 1970s. Pollution from local sources According to the Clean Air Network (a local NGO formed in 2009 with the purpose of urging the government to take appropriate steps to tackle the pollution problem), 53 percent of Hong Kong pollution comes from local sources – power stations, idling engines and marine emissions. Entry is made along a footbridge and through two steel doors. It is comparable to the rate in Asia’s less developed cities, where an average of 30% of water is lost. There are current concerns regarding its continued availability and whether Hong Kong can become less dependent on this source and more self reliant widening the water catchment area and resurrecting the notion of a desalination plant.A thread running through the article is about a visit Martin made to High Island reservoir and I thought this would be of particular interest.

It has been affected by pollution as Guangdong province has rapidly industrialized and urbanized. Perhaps 60 metres doesn’t sound that many, but picture being 12 storeys or more up a building and looking down an empty lift shaft. It undertakes research in three major ideas: air quality, nature conservation and urban environment, with an overarching framework of promoting wellbeing. Other reservoirs mentioned are Pok Fu Lam, Tai Tam, Aberdeen, Shing Mun and Plover Cove.Martin mentions the periods when Hong Kong has experienced chronic water shortages. Hong Kong can no longer afford to live with the illusion that is has an abundance of water.Civic Exchange is an independent public policy think tank based in Hong Kong. “It’s an inverted pendulum.”While I think of pendulums as swinging to and fro, as in a grandfather clock or terrorising the protagonist of an Edgar Allan Poe story, this one is stationary. We annually consume a total of 1.25 billion cubic metres of freshwater and seawater (mostly used for flushing toilets) – equivalent to nearly 860 full bathtubs per person. The article begins: Easily overlooked, Tower X, a concrete cylinder that’s perhaps as wide as a bus is long and mostly submerged, is topped by a concrete dome and narrow brim, shaped like a hat a Catholic priest might wear.Usually, the tower – which is on the south shore of High Island Reservoir, east of Sai Kung town, and named after its designation on Water Supplies Department (WSD) maps – is off-limits to the public, but I’m visiting with a small WSD team that includes engineer Patrick Fan Kwok-ning. Inside, we cross the concrete floor to the edge of a rectangular opening, where I lean on a metal railing and look down through the tower’s waterless interior.Inside Tower X at High Island Reservoir Photo: Martin Williams Courtesy: SCMP“It’s 60 metres to the bottom,” Fan says. Though multiple measures were made throughout its history, providing an adequate water supply for Hong Kong has met with numerous challenges because the region has few natural lakes and rivers, inadequate groundwater sources (inaccessible in most cases due to the hard granite bedrockfound in most areas in the territory), a high population density, and extreme seasonable variations in rainfall. In particular the severe drought of 1929 that lead to 70,000 people leaving the colony. Seepage of rain water through roof / podium / balcony / external wall / window of buildings. And those of 1963 and ’64 which led to violence at standpipes.Betwen 70 and 80% of Hong Kong’s water comes in from the Donjiang (East River) in Guandong.
