HARRIS COUNTY: Harris County began converting from exclusive groundwater use in the 1990’s after seeing the devastating impact of sinking (including the abandonment of some neighborhoods, flooding and faulting). They are building surface water treatment systems and phasing out groundwater.
MONTGOMERY COUNTY: In 2015 a new surface water treatment system started up on Lake Conroe.
With a capacity of 30 million gallons of water per day. A water distribution system was included to deliver water to more densely populated areas of Montgomery County.
This system has existing spare capacity, and can be expanded to deliver more water throughout the county.
BOTTOMLINE: Eventually we will need to move to surface water either because of sinking (like Harris County and other places around the world), or because the groundwater supply runs dry. Why not start now and avoid the damage that sinking will cause?
WHY THIS MATTERS: Our homes, roads and businesses are structurally supported by the water underground, so if we use too much groundwater we cause our land to sink. Parts of Montgomery County have sunk one foot in the past 20 years, and some areas are expected to sink 3 MORE feet by 2080. This sinking is irreversible and causes damage to our homes, roads and businesses from flooding and fault activation.
OUR RECOMMENDATION: Rather than increasing groundwater use and risk irreversible and negligent subsidence, we should limit groundwater use to prevent subsidence, and ramp up use of surface water to meet growing demand.
