The Data Bank Division assists Water Districts in establishing their own Groundwater Data Banking and Monitoring system. The objective is to institutionalize groundwater data banking at the water district level and utilize the data bank as a tool in groundwater management and in assessing groundwater availability through the establishment of a continuing monitoring program for groundwater levels, extraction rates and water quality conditions.

Available data encoded in the LWUA Groundwater Data Bank are processed and presented in a concise and easy-to-reference report.

The Division provides training to Water District's technical staff on groundwater data banking and monitoring through on-the-job training and formal seminars.
