For those of us paying attention to the weather in Santa Fe, a question increasingly coming up these days is when are we going to see watering restrictions? Especially since this is the driest it has been in a long time. Average precipitation for Santa Fe this time of year is normally 4.81 inches, and so far we have only received 0.67 inches, or 13.9% of average. It is worse for Albuquerque, which has seen only 0.19 inches thus far this year. Most of our state is experiencing a drought, as well as Arizona and Texas. Santa Fe has not seen this little precipitation since records have been kept. We should be extremely concerned about our water situation.
During our last severe drought in 2002, the city was within weeks of running out of water. The drought is even worse this year, yet thanks to actions taken by the city and our community, we are not now in the dire situation we were then. Our water supply is much more varied and our water use is down.
Santa Fe no longer relies
almost solely on the Santa Fe Water Shed for our drinking water. The number of city
wells has increased from 2001 to today, (i.e. 5 more online today) our pumping
capacity has increased, plus the Buckman Direct Diversion (BDD) came online in
January of this year. Our available supply of water has increased to more than
22,000,000 gallons a day. Although this
supply is non-sustainable (i.e., we can't count on having this much water
available in the wells, BDD, or the reservoirs in the future), it is still a
major increase from what we were able to deliver a decade ago.
In years with typical snowfall and precipitation, we would now be using more water out of the Santa Fe Water Shed. Last year at about this time, our local reservoirs were at about 80% of capacity. This year they are at about 45%. So we are drawing down more of our reservoirs, and are pumping more out of the wells. These new supplies provide us an emergency insurance policy for the drought conditions we find ourselves in now.
Since 2001, water conservation has also played a key role in providing us a more reliable water supply. Santa Fe's population grew 9.2% from 2000-2010, while our per person water usage dropped 28%. In 2001, we were using approximately 139 gallons per person per day, and today we are using less than 100 gallons per person per day.
But even with increased reserves
and conservation, our current dry conditions are so severe that most of us are
expecting the city to announce water restrictions. Our former tiered drought
alert system, in use until recently applied a set of restrictions for each
level of drought. Our city updated this system in 2007. Under Ordinance
#1988-36, in Water Chapter 25, the Water Division Director issues a drought alert based on the
following set of conditions: 1) A general water supply shortage due to
increased demand or limited supply; 2) Distribution or storage facilities of
the city water system are inadequate to meet demand or minimum quality
standards; 3) A disruption of the supply, storage, or distribution facilities
of the city water or wastewater systems; 4) An unforeseeable disaster or water
emergency such as an earthquake or other catastrophic event affecting the Santa
Fe or Rio Grande river watershed, or groundwater supply, or other major
disruption in the water supply or 5) A foreseeable water emergency, such as
extended drought conditions (click on City Code and then Chapter 25).
Under this new plan, we have only emergency conditions: Orange and Red. Orange restricts watering to only twice a week and implements both pool filling and landscape planting restrictions. Red raises the bar and prohibits most landscape irrigation except with non-potable water (i.e., rainwater) and prohibits pool filling and car washing among other restrictions.
With our improved water supply and admirable water conservation efforts, don't expect Orange or Red restrictions to be announced anytime soon. However, a continued drought, fire in our water shed or any major unforeseeable event could drastically change our situation. The city of Santa Fe is doing their part; it is imperative we continue to conserve. It is one of the least expensive and most important actions we can take to ensure our water supply for today and future generations.
