Update on new SIMAPA well in West Ajijic; drilling has reached the water table. Water rates rise
New well in west Ajijic reaches the water table.
Patrick O’Heffernan, Ajijic. Ajijic’s seventh and newest water well has reached the water table in west Ajijic at 230 meters depth, but according to Ajijic-based SIMAPA representative Omar Gustavo Cerna López , the well will be drilled to 260 meters to provide a cushion that can assure a water supply even in the driest summer.
The drilling began on November 10 of last year in response to years of complaints of an unstable water supply in the La Mojonera neighborhood of the Rancho del Oro subdivision. The well will be the seventh well operated by SIMAPA to supply water to Ajijic, but will be a substantial help to a system stretched by Ajijic’s growth. Of the other six wells in the area, two provide half of the town’s supply; a seventh well in west Ajijic will add needed capacity to the system.
SIMAPA representative Gustavo Cena Lopez told Laguna in response to a question that there will be a 5% increase in water rates. But he did not say when it would take effect and if it would be systemwide or just for the area supplied by the new well.
Water from the new well will supply users from the municipal border with Jocotepec to the La Cristina area. Gustavo Cena López told Laguna that as of now there is no set completion date for the well but it should be relatively soon. Drilling must go down another 30 meters and the drilling time will vary depending on the rock layer it is drilling through and construction time for the3 ancillary equipment needed for operation. However, he noted that as of now it is on schedule.
After the well reaches 260 meters, the necessary equipment for water extraction and storage will be installed, the water will be tested for quality, and a supply pipe will be laid from the well to the water main in the Carretera. From there, existing lateral pipes will distribute the water to homes and businesses. There may be some properties that are currently not supplied with water that will have to connect to the main if they want service from the new well.
Omar Gustavo Cena Lopez pointed out that the 260 meter level is well within the average depth of the water table in Ajijic, which has not fluctuated noticeably over the past five years. In the summer season when people need more water for irrigation and domestic use, it drops; and in the rainy season the water table rise, but the fluctuations are always within a normal range easily accessible by existing wells. Recharge rate of the water table has remained virtually the same for many years and is not expected to drop.
Omar Gustavo Cena Lopez was not able to provide cost figures for the project, referring Laguna to the information office in Chapala. The office did not have this information when Laguna requested it, but it may be available when the well is complete.
