Heavy water is less dissociated than light water at given temperature, and the true concentration of D + ions is less than H + ions would be for light water at the same temperature. The same is true of OD − vs. OH − ions. For heavy water Kw D 2 O (25.0 °C) = 1.35 × 10 −15, and [D + ] must equal [OD − ] for neutral water
Agricultural water management in the Philippines is primarily focused on irrigation. The country has 3.126 million hectares of irrigable land, 50% (1.567 million hectares) of which already has irrigation facilities. 50% of irrigated areas are developed and operated by the government through the National Irrigation System (NIS). 36% is developed by the government and operated by irrigators ...

It can store water that is good for 19 days of Manila Water's supply requirements. Its critical dam level is at 69 meters above sea level. Manila Water has also begun drawing water from the Laguna de Bay, which is treated in and distributed from the Cardona Water Treatment Plant located in Brgy. Del Remedio, Cardona, Rizal.
A residential water bill for the same consumption in West Manila was 489 Pesos/m3 (US$12) or 16 Pesos/m3 (US$0.39/m3). A residential water bill for a minimal consumption of 10 cubic meter per month, however, is only 109 Pesos (US$2.60), corresponding to only US$0.09/m3.
Water portal; Tritiated water is a radioactive form of water in which the usual protium atoms are replaced with tritium atoms. In its pure form it may be called tritium oxide (T 2 O or 3 H 2 O) or super-heavy water. Pure T 2 O is a colorless liquid, [1] and it is corrosive due to self-radiolysis. Diluted, tritiated water is mainly H 2 O plus ...
