				 "Tip #3: Toilets can leak at a rate of 200 gallons a day, which can add up to 73,050 gallons of water a year. To find out if you have a leak, place a drop of food coloring in the tank. If the color shows in the bowl without flushing, you have a leak."], "3"

				"Tip #11: Water the root zone of the plant instead of the foliage. This saves water and reduces diseases.",
				"Tip #12: Water at night or in early morning to avoid losing water to evaporation.",
				"Tip #13: Water deeply. Light, frequent watering causes shallow rooting and increases the need for water.",
				"Tip #14: Use drip irrigation and micro-sprays when possible. They use 30 to 50 percent less water than sprinklers.",

				"Tip #18: Consider the slope and drainage patterns of the site. Plant moisture-loving plants at the base of slopes where they can take advantage of natural drainage.",
