  • 1. FALL 2011 WHCRWA PLANS FOR WHCRWA BOARD NEXT CONVERSION MILESTONE OF After meeting its 2010 deadline for conversion to surface water ahead of schedule, DIRECTORS the West Harris County Regional Water Authority is deep in planning for an even more ambitious milestone in 2020. Bruce Parker, President Construction has slowed for the time being, but Authority engineers are still busy Voting District 2 behind the scenes with maps and survey equipment, doing the important preliminary work necessary for a massive cross-town construction project expected in the next decade.

Currently, 38 districts – in an area roughly between West Road on the north, Clay Road on the Johnny Nelson, Director south, Brittmoore Road on the east, and Barker-Cypress on the west – are receiving surface water from the City of Houston system, via the Authority. Voting District 9 The next 2020 deadline raises the mandate to 70 percent. To meet that goal, the Authority is partnering with the North Fort Bend Water Authority to build a 9-mile- Larry Weppler, Director long, eight-foot diameter water line from Houston’s northeast water plant near Lake Voting District 1 Houston, and a 30-mile-long, eight-foot diameter water line crossing Harris County.Mark G.

  • 2. The Truth About Turf and Water Use... Lawns don’t waste water...people do! As recently as a decade ago, how many of us would have thought we’d need to worry if we’d have enough water to keep up our lawns and landscape areas? This is Texas, isn’t it? Surely there’s enough water to go around? Perhaps not in years ahead, however, if you take a close look at the Texas Water Development Board’s State Water Plan. In fact, reading it is enough to make you concerned - very concerned - about having adequate water supplies for our children and grandchildren by 2050. Forty years...seems like an eternity away, doesn’t it? It can take at least that long to realize the benefits of long-range plans“The bottom line when it comes to water infrastructure. Consider, for example, what would have happened if the City of Houston’s visionary planners is that people in the 1950’s hadn’t been as forward looking as they were to build reservoirs and lakes. We most certainly would not be in as good a need to know position as we are today relative to current water supplies. Thanks to their foresight, we’re able to rely on both ground and surface water to help meet the needs of our growing population. more about So, back to the water problems at hand. Is it time to forfeit dreams of the coveted Yard of the Month award? To take on thewhich turfgrass homeowners association, strip the grass out of your front yard and maybe fill in with rocks and cactus? Don’t go to those extremes justthey plant and yet. There may be a more positive alternate direction for you to consider.

According to Dr. David Chalmers, Texas AgriLife Extension long-term.” professor and co-author (with Dr. James McAfee) of Turfgrass Selection for Texas and Turfgrass Establishment for Texas, “The bottom line is that people need to know more about which turfgrass they plant and how to care for it in the long-term.” Dr. Richard White, also a TAMU Professor, mentioned that a survey of some 800 residents revealed that when it came to water usage, 25 percent of the respondents used 50 percent of the available drinking water.

Water providers agree that water conservation is the right thing to do. With the drought today, however, water conservation may be the only thing we can do. With that in mind, water suppliers are asking everyone to do what they can to use water efficiently to help stretch this precious resource.  6
