Save Palo Alto’s Groundwater is a citizens’ group organized through conversations among neighbors and families concerned with the environmental and property impact of the practice of “dewatering,” during the construction of residential basements. Dewatering involves the pumping out of millions of gallons of groundwater when basements are built in areas with high water tables. This pumped water is then dumped into our storm drains and ends up in the San Francisco Bay.
Save Palo Alto’s Groundwater is requesting that the City of Palo Alto require that developers/owners building basements in areas with high water tables use best construction practices such as limiting the duration and depth of dewatering and/or using “silent piling” and other techniques to minimize the amount of water extracted during this construction. Furthermore, we request that all water extracted be used, for example, for irrigation, for fire hydrants and other non-potable uses and/or recharged back to the aquifer.
Water is too precious a resource to be wasted and current City policies regarding dewatering do not take into account the possible need of this water to mitigate future droughts nor its beneficial effects of supporting our canopy, our properties and our infrastructure.
