San Diego officials have proposed a water and sewer rate hike to update city infrastructure as large changes are on the horizon, it was announced last week. The city is looking to increase wastewater rates by 5 percent starting January 2022, the first rate hike for that service in a decade. In addition, the city’s Public Utilities Department — which provides water and sewer services to customers, including Rancho Bernardans — is proposing to pass regional water cost increases to its customers in a 2 percent rate hike starting in 2022.
