One of the suppliers of Dallas’ water is being proactive in its handling of the lingering drought by starting dredging operations in one of its key reservoirs in order to increase available water.
The North Texas Municipal Water District is taking on a $1.9m project to clear out around 10 feet of silt that has accumulated around Lavon Lake’s intake pipes. Out of three intake pipes, two of them are affected by the silt buildup. Dredging will allow the utility to deliver up to an additional 7.2 million gallons per day.
Denise Hickey, a district spokeswoman, explained that water level in Lavon Lake was currently around 480 feet above sea level, but summer usage and evaporation could easily drop that level by 5 to 10 feet. Unless steps are taken, there will be serious consequences in pumping raw water if the level much further. Water pump #2 would cease to function at 470 feet and pump #3 would follow suit at 469 feet.
The dredging project was approved in February but will not commence until the week of March 9. One possible hold up would be if too much rain were to raise the water level before the dredging can be accomplished.
Five years of drought have fueled the need for water conservation and increased access to water sources. Calling upon the services of brochure printers can expedite both strategies.
