1. Groundwater level: The purpose of drilling wells is usually to obtain groundwater, so the depth of groundwater level will directly affect the depth of drilling wells. If the groundwater level is shallow, the drilling depth may be small; If the groundwater level is deep, the drilling depth may need to be deep.
2. Geological conditions: Different areas have different geological conditions. Some areas may have shallow strata, and some areas may have deep strata. The drilling depth will also change according to the geological conditions.
3. Water demand: The drilling depth can also be determined according to the water demand. If you need a lot of water resources, you may need to dig deeper wells to get more groundwater.
Generally speaking, the depth of drilling wells in Lianjiang area is generally tens to hundreds of meters. The specific depth needs to be determined according to the local geological survey and demand, so it is best to consult a professional water well drilling company or water department before drilling a well to obtain more accurate information and suggestions.
