in winter, when water use averages a million gallons a day. But in summer, two often chug away as all those water sprinklers and swim- ming pools triple demand. The third serves as a backup. The trip through the water pump isn't for anyone who suffers from vertigo. Water pres- sure is increased through the spinning motion of centrifugal force. Once up to speed, we're propelled into the water system. If demand is low, we could end up in one of the storage tanks for a spell. They can hold a total of 2.7 million gallons. Unlike in Wellesley, where topography varies enough for underground tanks at high ele- vations, Weston relies on elevated outdoor tanks. That way, when demand increases in the morning, gravity tugs water back into the system. You'd think that the pressure would be highest near a tower, but as Weston's water superintendent, David L. Fava, points out, the pressure rises as the flow gains momentum. Since its water comes straight from the MWRA, Weston typically does not have to treat it. However, sensors at the pumping station do monitor the levels of monochlo- ramine. An alarm is triggered if the level falls. If necessary, the MWRA can deploy a portable disinfectant system. Water is tested for bacteria at five sites around town every week. In addition, Fava and his crew regularly monitor the pumps, water pressure levels, and reservoir tank levels. The water crew inspects the vents and over- flow outlets of the reservoir tanks monthly to make sure screens are in place so no birds or other critters can get in. Our fantastic voyage has now come to an end, but it's good to know that the work to keep our water safe and clean goes on. 105 s u m m e r 2 0 1 6 | W e l l e s l e y W e s t o n M a g a z i n e FOR MORE ON WESTON WATER, visit weston.org/306/Water-Division; for Wellesley, visit wellesleyma.gov and type "water" in the search box.
