3. ROLES AND RELATIONSHIPS
Producer
Permittee or Entity responsible for the Domestic Wastewater Treatment Facility
Provider
Entity responsible for SUPPLYING Reclaimed Water to Users
Provider may or may not be the Producer
User
Entity receiving and USING the Reclaimed Water
User may or may not also be the provider or the producer

4. WHAT IS RECLAIMED WATER
Requirements:
Reclaimed water is water that has been treated to at least the PRODUCER’S wastewater permit effluent concentration limits
Only On-Demand use
Permit must provide for an alternative method of disposal when there is no demand for reclaimed water
Discharge
Land Application

5. TYPES OF RECLAIMED WATER
TYPE I - For use where contact between water and humans is likely
Specific Allowed Uses:
Irrigation of parks, athletic fields, school yards, and residences
Wading, boating or fishing in impoundments
Fire protection - internal sprinklers or hydrants
Food crop irrigation where water may contact edible portion
Irrigation of pastures for milking animals
Toilet or urinal flushing
Any Type II use

6. TYPES OF RECLAIMED WATER (CONT’D)
TYPE II - For use where contact between water and humans is unlikely
Uses:
Irrigation of sod farms, silviculture, limited access highway rights of way, and other remote sites (sites not used by public during irrigation)
Maintenance of impoundments or natural water bodies – no direct human contact
Soil Compaction and Dust Control in construction sites – minimal aerosol drift
Food Crop Irrigation where water will not contact edible portion
Cooling Tower make up water
Irrigation of animal feed crops other than pastures for milking animals

7. RECLAIMED WATER QUALITY STANDARDS
Type I
BOD5 or CBOD5 5 mg/l
Turbidity 3 NTU

Fecal Coliform or E. Coli 200 CFU/100 mL (30-day geometric mean)
Fecal Coliform or E. Coli 800 CFU/100 mL (max. single grab sample)
Enterococci 35 CFU/100 mL (30-day geometric mean)
Enterococci 89 CFU/100 mL (max. single grab sample)
Notes:
The standards represent 30-day average

10. SAMPLING AND ANALYSIS Type I Reclaimed Water Uses – Twice per week
Type II Reclaimed Water Uses – Once per week

11. RECORD KEEPING AND REPORTING
The reclaimed water provider or producer shall report to the commission on a monthly basis the following:
Volume of reclaimed water delivered to a user or provider
Quality of reclaimed water delivered to a user or provider reported as a monthly average, except those listed as maximum single grab sample, for each quality criteria
Notes:
Notify TCEQ at least 30 days before reclaimed water is distributed
The facility will be issued monthly effluent report (MER) forms for reporting quality and quantity of reclaimed water used
