Wastewater Service Billing

OMWD provides wastewater (sewer) service to the communities of 4S Ranch, Rancho Cielo, Santaluz, Black Mountain Ranch/Heritage Bluffs, and Avion. Within OMWD’s boundaries, seven other agencies provide wastewater service, depending on property location: City of Encinitas, City of San Diego, City of Solana Beach, Leucadia Wastewater District, Rancho Santa Fe Community Services District, Whispering Palms CSD, and Fairbanks Ranch CSD.

Many agencies providing wastewater service, including OMWD, calculate wastewater service bills based in part on water consumption at the property. Therefore, higher water consumption can lead to higher wastewater service bills. For those customers whose water and wastewater service needs are served by different agencies, water usage data may be exchanged between agencies. For example:

  • For customers who receive a wastewater service bill from OMWD and a water bill from the City of San Diego, the City provides water usage data to OMWD.
  • For customers who receive a wastewater service from the City of San Diego and a water bill from OMWD, OMWD provides monthly water usage data to the City. The City bases the wastewater service charge on winter usage. If a customer’s water usage is higher this winter than it was in the previous year, the wastewater service bill may also be higher. For questions about how the City calculates wastewater service bills, visit the City’s website.

OMWD wastewater service charges are calculated once a year and most customers pay for wastewater service on their property tax bills to the County of San Diego’s Tax Collector office. Each parcel receives one wastewater assessment. If a parcel has multiple water meters, the property tax bill will reflect a total of all wastewater assessments. Irrigation meters are not included in any calculations.
