The City of Santa Fe Water Division is prepared to tap into more groundwater to meet this summer’s water use demand

The City of Santa Fe Water Division is prepared to tap into more groundwater to meet this summer’s water use demand. As Rio Grande and upper Santa Fe River surface water levels decrease, the municipal water system can switch from relying on surface water for daily water use and rely more on wells that draw groundwater from the aquifer.
The city’s approach to coping with the drought begins with a variety of planning documents, ordinances and operations plans. The city has invested in a robust and diverse portfolio of surface and ground water supplies to ensure Santa Fe’s water supply is here for the long-term so that we can manage for drought conditions. Santa Fe’s water comes from the Buckman well field, the city well field, the Canyon Road Water Treatment Plant treating Santa Fe River water, and the Buckman Direct Diversion on the Rio Grande. Surface water diverted from the Rio Grande and the upper Santa Fe River, are the primary sources of water for the city.
“Santa Fe has a very diversified and sustainable water supply – two surface water sources that are derived from the two different regional water basins (San Juan- Chama basin via the Rio Grande and Upper Santa Fe River Watershed) and two groundwater resources- something very rare in the American Southwest,” said Rick Carpenter, city water resource and conservation manager. Groundwater is pumped as needed to supplement surface water supplies.
The city’s fresh water supplies are also supplemented by a significant amount of reclaimed treated wastewater. The reclaimed wastewater is put to non-potable beneficial use in a variety of ways which helps offset what otherwise might be uses requiring irrigation from potable sources.
“Using more groundwater when surface water is less available has always been the plan. By resting the aquifer over the last four years, we’ve stretched the available groundwater supplies, which we can turn to in this third year of drought,” stated Carpenter.
Year-round water restrictions also play an important part in the city’s water resource planning. “Most Santa Feans are water warriors, using an average of 59 gallons per person per day, less than most in the Southwest,” said Laurie Trevizo, city water conservation manager.
Currently, the city’s water demand is being met by water system supply. However, if this situation changes, the City Council can declare emergency water restrictions and invoke the Emergency Water Management Plan in two stages – water warning orange and water crisis red – with restrictions that increase with the level of the emergency. Water Warning Orange begins when the water system can only supply 80 percent to 99 percent of operational water demand. Water Crisis Red begins when our water system can supply less than 80 percent of demand. In Water Crisis Red nearly all outdoor irrigation using potable (drinking water) is prohibited. Gray water use is not restricted.
