Because of groundwater pumping restrictions and reliability concerns, Houston, Texas, has embarked on an accelerated conversion project to increase the amount of water it provides to its northwestern section. The $150-million Accelerated Surface Water Transmission Program is the latest in a series of multiyear, multimillion-dollar pipeline projects begun by Houston in 1985 to convert its water supply from primarily a groundwater system to one that relies on surface water. The conversion, which has already placed more than 100 mi of 24 to 96 in diameter surface water transmission pipes in the city, is mandated by the Harris-Galveston Coastal Subsidence District to reduce subsidence and supplement decreasing groundwater capacity.
