How much is the service deposit?

Bills, Payments, Rates & Fees

The service deposit equals two months of your estimated service charges, calculated using either the flat rate or estimated metered usage.


Every customer receiving water service must pay a service deposit for every service connection, structure, commercial unit, or dwelling unit served. The deposit amount is designed to cover approximately two months of service.

Deposit calculation: The deposit is the higher of:

  • Two months of flat rate service charges, OR
  • Two months of estimated metered charges (meter charge plus estimated volume charge)

Example deposit amounts:

Flat rate residential (single-family home):

  • $76.94 × 2 = $153.88 deposit

Flat rate commercial:

  • $87.04 × 2 = $174.08 deposit

Metered service (3/4" meter, estimated 5,000 gal/month):

  • Monthly estimate: $84.23 + (5 × $5.36) = $111.03
  • Deposit: $111.03 × 2 = $222.06

Multi-unit example (duplex, flat rate):

  • Monthly: $76.94 × 2 units = $153.88
  • Deposit: $153.88 × 2 = $307.76

What you’ll receive: The utility will provide you with:

  • Written receipt for your deposit
  • Copy of the deposit section of the tariff

When you get your deposit back: Your deposit will be refunded within 30 days after:

  • Two years of on-time payment history, OR

Whichever comes first. Any charges on your account will be deducted before refund.
