25-30.055. Systems with a Capacity or Proposed Capacity to Serve 100 or Fewer Persons

(1) A water or wastewater system is exempt under Section 367.022(6), F.S., if its current or proposed water or wastewater treatment facilities and distribution or collection system have and will have a capacity, excluding fire flow capacity, of no greater than 10,000 gallons per day or if the entire system is designed to serve no greater than 40 equivalent residential connections (ERCs). For purposes of this rule only, one ERC equals 250 gallons per day. (a) Unless the Commission determines that valid local statistical data should be used, ERCs for residential use are as follows: Single family detached dwellings 1 ERC per unit Multiple family dwellings .8 ERC per unit Mobile homes .8 ERC per unit (b) ERCs for nonresidential use shall be based on meter size and type as follows: 1. For Water Systems Meter Size Meter Type ERCs 5/8'' Displacement 1.0 3/4'' Displacement 1.5 1'' Displacement 2.5 11/2'' Displacement or Turbine 5.0 2'' Displacement, Compound or Turbine 8.0 3'' Displacement 15.0 3'' Compound 16.0 3'' Turbine 17.5 4v Displacement or Compound 25.0 4'' Turbine 30.0 6'' Displacement or Compound 50.0 6v Turbine 62.5 8'' Compound 80.0 8'' Turbine 90.0 10'' Compound 115.0 10'' Turbine 145.0 12'' Turbine 215.0 2. For Wastewater Systems Meter Size Meter Type ERCs 5/8'' Displacement 1.0 3/4'' Displacement 1.5 1'' Displacement 2.5 11/2'' Displacement or Turbine 5.0 2'' Displacement, Compound or Turbine 8.0 3'' Displacement 15.0 3'' Compound 16.0 3'' Turbine 17.5 4'' Displacement or Compound 25.0 4'' Turbine 30.0 6'' Displacement or Compound 50.0 6'' Turbine 62.5 8'' Compound 80.0 8'' Turbine 90.0 10'' Compound 115.0 10'' Turbine 145.0 12'' Turbine 215.0 (c) Where undeveloped land is adjacent to a system or proposed system the Commission may, where appropriate, estimate ERCs for service to future development on the adjacent undeveloped land. Unless the Commission determines that valid local statistical data should be used, ERCs for residential acreage should be estimated as follows: Residential Use ERCs/Acre Mobile home 4.8 Detached single family 4.0 Estimates for other types of residential acreage and for commercial and industrial uses shall be made on a case by case basis.
