Dedicated Irrigation Meter – Yes or No?

A dedicated irrigation meter, or lawn meter, is a water meter that only meters water used for outdoor watering, irrigation, pool fills or other uses that do not return water to the City’s wastewater system for treatment and disposal.

Should you have one?  The answer is maybe. It depends on how much water is used monthly at your home. Use our worksheet to estimate your benefit.

In general, locations where monthly water use is equal to or less than average residential use – 8 ccf – are less likely to benefit from a lawn meter.  Locations with more than average monthly water use may benefit by being billed for actual rather than estimated outdoor water use.

Residential accounts in Tampa, where a dedicated irrigation meter is not present, receive a lawn credit, or sewer max, when a lawn meter is not in use. The lawn credit “caps” the amount of water to which monthly wastewater costs are billed by estimating the portion of total water use returning to the wastewater system.

The lawn credit is location specific and is based on past water use history at that site. Lawn credits are recalculated annually in January based on the billing history for the previous twenty-four months.

At locations where a dedicated lawn meter is in use, no lawn credit is applied. Water billing is based on the total amount of water passing through the primary service meter and the lawn meter. Wastewater billing is based on the amount of water passing through the primary service meter.
