Well Decommissioning in Chino
Well decommissioning — the permanent, proper sealing of an unused well — is required by California law and San Diego County regulations. Whether you're selling property in Chino, replacing an old well with a new one, or have inherited a property with an unused well, decommissioning protects groundwater and eliminates liability.
When Decommissioning Is Required
- Property sale — title companies and lenders often require proof that unused wells are properly sealed
- Well replacement — when drilling a new well, the old one must be decommissioned
- County compliance — San Diego County can require decommissioning of neglected or unsafe wells
- Contamination risk — wells near septic systems, agriculture, or development that weren't properly sealed
Decommissioning Standards
California Well Standards (Bulletin 74-90) require wells to be sealed with neat cement grout, sand cement grout, or concrete from the bottom up. The annular space (gap between casing and borehole) must also be sealed. We follow all state and San Diego County requirements and file the proper destruction reports.
Cost & Timeline
Most residential well decommissioning in Chino costs $1,500-$4,000 and takes one day. Factors that affect cost include well depth, casing diameter, accessibility, and whether equipment needs to be removed first. We handle the entire process including permitting and county filing.
