The good news for Beijing's Olympics organisers is that they will have enough water and gas, but they still need to work on vegetables and tourists.
Final preparations for next month's Games are in full swing, with booths of smiling volunteers and flower tubs sprouting across the city.
And it seems Herculean efforts to ensure the capital will not run dry, despite several years of drought, have paid off: the main reservoirs feeding the capital are holding more than enough water for the one million or more domestic tourists and up to 500,000 foreign visitors expected during the Games.
"Beijing has combined all water resources, including reservoirs, underground water and rainfall, to ensure the supply for the Olympics," Yu Yaping, a Beijing Water Bureau official, said in remarks reported by Xinhua news agency.
To ensure there was no risk of Beijing running short for the Games, officials ordered a 309-kilometres northern section of the larger South-North Water Transfer Project first be completed to pump more water if needed from Hebei, a largely rural province adjoining the capital that is itself acutely short of water.
The authorities are also stockpiling plenty of petrol and diesel, even though cars will be allowed on Beijing's road only on alternate days from this Sunday.
PetroChina and Sinopec, China's two leading oil producers, are expected to import 310,000 tonnes of petrol and 410,000 tonnes of diesel for use in eastern China, according to ChemNet, a chemical and petrochemical industry information website.
By contrast, supplies of vegetables coming into Beijing have dropped about 10 per cent recently, pushing up prices by an average 65 per cent, according to Wang Xiaodong, the director of the city's agricultural office.
From July 20, authorities in Hebei will check all vehicles headed for Beijing from more than 50 towns and cities, according to a local media report. Security will also be stepped up at airports, railway stations and airports, the report in the Yan Zhao City Journal said.
Travel agents and sports hospitality companies are worried that stifling security, difficulties obtaining visas and recurring warnings about the threat of terrorism will keep many tourists away from the Games, which run from August 8-24.
Five-star hotels are more than 77 per cent booked for the Games, but the reservation rate at four-star hotels is only 48 per cent and is lower still at more modest hotels, Xiong Yumei, vice-director of the Beijing Tourism Bureau, said on Friday.
A 100,000-strong anti-terrorism force is in place, surface-to-air missiles have been deployed around major venues and bag searches are being conducted on the subway.
