Water Stewardship

Guidelines for Minimum Standards in Water Well Construction, Province of British Columbia — June 1982

• Note: this document is a historical document and has now been replaced by the Ground Water Protection Regulation (GWPR). It is provided here as useful guidelines for those items the GWPR does not yet address (e.g., pump installation) but the GWPR supersedes the guidelines.
