Mail, text, and in-person payment instructions
Pay by text
Sign in to the Helix online account, select Your Account at a Glance, choose Pay by Text, check the enrollment box, and save. Helix sends the amount due and due date by text; the customer replies “Ok” to authorize immediate payment with the credit card, debit card, or bank account already configured in the online account, then receives a confirmation text. Paperless-billing reminders also arrive by email or text. Customers should enroll only through the official CSS portal rather than replying to an unsolicited payment request.
Mail-in address
Helix Water District, 7811 University Avenue, La Mesa, CA 91942. Helix’s published payment page instructs customers to mail the water-bill payment to the administration office address; customers should include the bill stub and account information and avoid mail when the account is near shutoff because postal delivery can delay crediting.
Counters, drop boxes, and office hours
Helix Customer Service and Administration Office, 7811 University Avenue, La Mesa, CA 91942, has a lobby open Monday–Friday 8:30 a.m.–5:00 p.m., excluding District holidays. A payment kiosk outside the Quince Avenue lobby entrance operates 24/7 and accepts cash, personal/business checks, and credit/debit cards; cash and checks are free, while cards carry the $4.50 vendor fee and a $600 transaction limit. The kiosk posts payments immediately and provides a receipt. The office lobby accepts cash, personal/business checks, cashier’s checks, and money orders. No separate customer billing counter is published at the El Cajon Operations Center or Lakeside treatment plant.
