Johor–Singapore Causeway, that also carries a road and a railway. Imported water has gradually reduced over the years; as of 2009, imported water had been reduced from 50% previously to 40% of total consumption. After the expiry of a 1961 water agreement between Malaysia and Singapore in 2011, two agreements are in force now. One was signed in 1962 and another one in 1990. Both will expire in 2061. Under the first agreement the price of raw water was set at 3 Malaysian sen per , corresponding to about 0,2 US cents per cubic meter. Under this agreement Singapore is entitled to receive up to per day, corresponding to 56% of its water use of in 2011. Furthermore, under the 1990 agreement, Singapore is entitled to buy an additional unspecified quantity of treated water from the Linggiu Dam at a price that is higher than under the previous agreement. Reclaimed water In Singapore, reclaimed water is branded as NEWater and is bottled directly from an advanced water purification facility for educational and celebratory purposes. Though most of the reused water is used for high-tech industry in Singapore, a small amount is returned to reservoirs for drinking water. NEWater is the brand name given to ultra-pure water that is produced from reclaimed water. Wastewater, which is called "used water" in Singapore, is treated in conventional advanced wastewater treatment plants that are called reclamation plants in Singapore. The effluent from the reclamation plants is either discharged into the sea or undergoes further microfiltration, reverse osmosis and ultraviolet treatment. Reclaimed water provides 40% of Singapore's water requirements. Using the NEWater technology, cleaned water is recycled to create ultra-clean, premium reclaimed water. Up to 55% of Singapore's water demand is anticipated to be satisfied by NEWater by 2060. The quality of NEWater is monitored by, among others, an international panel of experts and exceeds the World Health Organization (WHO) standards for drinking water, much higher than imported water. In 2012, there were four NEWater factories, located at the Bedok, Kranji, Ulu Pandan and Changi next to five water reclamation plants. At the end of 2002, the programme had garnered a 98 percent acceptance rate among Singaporeans, with 82% of respondents indicating that they would drink the reused water directly, another 16% only when mixed with reservoir water. The produced NEWater after stabilization (addition of alkaline chemicals) is in compliance with the WHO requirements and
