Well Water Management
Wells pump water directly from groundwater. The quality of the well water is highly variable among wells and locations, as it is dependent upon the quality of the groundwater. Non-regulatory guidelines exist to evaluate groundwater suitability for irrigation purposes. The characteristics of groundwater used for irrigation purposes are assessed based on the potential of salt accumulation in the soil, specific types of toxicity from root and foliar absorption, adverse affects on soil structural properties, and the potential of plugging irrigation filters, drip or microsprinkler emission devices. Proper nutrient and water management techniques help protect surface and groundwater quality by reducing nutrient movement. The District offers basic well water analysis.
Well Best Management Practices include (but are not limited to):
- Creating a zone of protection around the well. A 50 foot diameter zone is generally recommended. Keep activities in this zone to a minimum to protect the well and groundwater.
- Inspect the wellhead on a regular basis. Cracks or openings can lead to contamination.
- Protect the well structure from physical damage.
- Maintain your septic system (if applicable). A 100 foot setback is required between your well and your septic system to prevent contamination; however, contaminants from poorly maintained septic systems can cause water quality issues.
Pumping Plant Efficiency
Pump testing is an on-site evaluation of the pumping plant’s performance while the pump is operating. The evaluation encompasses the measuring of total head, pump capacity, and input horsepower to the pump. This information is used to calculate the overall pumping plant efficiency (the combined efficiency of the pump and motor or engine). A pump efficiency test requires access inside the well casing to measure the groundwater level, obtain an accurate measure of flow, and to be able to accurately measure the irrigation system’s water pressure. Pumping plant efficiency tests are provided to the District’s residents for a nominal fee.
