Water and sewer rates for Padre Dam Municipal Water District customers are about to go up.

The board of directors of the Santee-based district is holding a public hearing June 21 to vote on proposed increases and adjustments to water and sewer rates, and service charges.

The rate hikes, if approved, would take effect in November. The average residential Padre Dam customer would pay $154.75 a month for water and sewer services, up from $151.
