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.
