The City administers several regulatory programs to monitor and prevent possible sources of contamination or damage to our water distribution, and wastewater collection and treatment systems.
The goal of the Cross Connection Control Program is to eliminate possible sources of potable water system contamination by identifying cross-connections, and requiring that appropriate backflow prevention assemblies be installed and maintained by water customers. A cross-connection is an actual or potential connection between a potable water system, and any source or system containing non-potable water or other substances. An example of cross-connection is the piping between a public drinking water system and a landscape irrigation system. In any instance of a cross-connection, there is an opportunity to introduce contaminants into the potable water system due to the occurrence of backflow.
A backflow prevention assembly is a mechanism that provides a physical barrier to backflow. To protect the public drinking water system, the City requires that an approved backflow prevention assembly be installed and maintained by the water customer, at the water service connection to each system or premises that poses a significant risk to the public water system.
Water customers that are required to install and maintain a backflow prevention assembly include, but are not limited to: reclaimed water customers, hospitals and medical centers, restaurants and food processing facilities, car washes, dry cleaners and other chemical-handling businesses, and large irrigation systems.

Do I need a Waste Discharge Authorization Permit?
Permits. The City requires certain businesses to submit a permit application and an environmental survey, along with baseline pollutant monitoring. City permit managers use this information to develop fact sheets identifying regulatory issues, discharge limits and monitoring requirements. Pretreatment staff write permits based on regulation of the wastewater characteristics and compliance with discharge standards. Click on the link for a Waste Discharge Authorization Application.
Fats, oils and grease (FOG) are known to accumulate in the sewer collection system and can cause blockage and odor issues. As a result, commercial food service establishments are required to prevent the discharge of fats, oils and grease into the sewer collection system. The most common FOG pretreatment device is the gravity grease interceptor (GGI) and most food service establishments are required to have and maintain a GGI or similar device. Click Grease Interceptor to learn how to maintain your grease interceptor. Regulaciónes Para Interceptores de Grasa.
For information on the City's legal authority to implement and enforce this program, please refer to Chapter 14.09 of the Henderson Municipal Code.

Fixture Verification Program
The Fixture Verification Program helps the City maintain an accurate count of plumbing fixtures associated with each commercial account so we may bill each account appropriately. This program enables the City to more accurately project the timing of wastewater collection and treatment system upgrades and ensure continued, uninterrupted service to our customers.
As part of the fixture verification process, City staff will visit customer properties on a periodic basis to verify that the number and type of plumbing fixtures at each location match what we have in our records. If your property is selected for fixture verification, we will contact you to let you know when to expect our visit, and arrange access to the necessary areas.
Mercury is a potent neurotoxin that bioaccumulates in the environment. Mercury pollution is a widespread global concern that originates from many diverse sources. When improperly disposed or washed down a drain, dental amalgam waste from dental practices is a significant source of mercury releases to the environment. In an effort to reduce the amount of mercury released into the environment, the Environmental Protection Agency (EPA) has promulgated new regulations intended to reduce discharges of mercury from dental practices into publicly owned treatment works (POTWs). The new dental office regulation is codified at 40 CFR Part 441 (§441). The §441 regulations went into effect July 14, 2017 and compliance with §441 is mandated by the following dates:
Existing Source (dental dischargers first discharge to the city’s POTW occurred on or before July 14, 2017) – must be in full compliance by July 14, 2020.
New Source (dental dischargers first discharge to the city’s POTW occurs after July 14, 2017) – must be in compliance within 90 days following the introduction of wastewater into a POTW.
In order to demonstrate compliance with the §441 regulations, dental dischargers are required to complete the following:
All dental practices are required to submit a one-time certification. Please complete and submit the Dental Practice Inventory and Certification Form.
Dental practices that are exempted from the §441 regulations only need to submit the one-time certification. (see §441c-f for list of exemptions)
Dental offices that are not exempt must also complete the following:
Install an amalgam separator(s) or equivalent device that is designed, operated, and maintained is accordance with the requirements specified in §441.30 or §441.40.
Implement the Best Management Practices (BMPs) identified in §441.30 or §441.40.
Keep records to document that the program requirements are being met – see §441.50 for record keeping requirements.
If you have any questions, comments, or concerns regarding the §441 regulations or the requirements, please contact Pretreatment at COHPT@cityofhenderson.com or (702) 267-2603, Monday through Friday from 6:00 a.m. until 4:00 p.m.
