The sewer collection system receives wastewater from homes, area businesses and industrial facilities.
Every user has the potential to impact the sewer collection system or wastewater treatment plant by dumping, pouring or flushing chemicals, solvents, pesticides, or fats, oils and grease (FOG) down the drain.
The Water Authority Southside Water Reclamation Plant (SWRP) removes harmful organisms and other contaminants from the wastewater before discharging into the Rio Grande, the receiving stream. Managing wastes before they enter the sewer collection system protects the treatment process at the SWRP.
The Water Authority Industrial Pretreatment Program is required by the U.S. Environmental Protection Agency (EPA) regulations (40 CFR 403) and the National Pollutant Discharge Elimination System (NPDES) permit for the SWRP.
The legal authority for the Industrial Pretreatment Program is the Water Authority Sewer Use and Wastewater Control Ordinance (SUO).
The program is required in order to :
- Protect the receiving water, the Rio Grande
- Protect the biosolids which are composted at the Soil Amendment Facility
- Protect the sewer collection system
- Protect SWRP workers including those who work on the collection system
- Prevent pass-through or interference with the wastewater treatment process
Violations of the SUO are handled according to the Enforcement Response Plan (ERP).
The Industrial Pretreatment Program has five (5) components:
