Why You Need a Backflow Prevention Device Certification
Aberdeen, South Dakota requires a Backflow Prevention Device Certification for food service establishments under the city's local sewer use regulations and water connection requirements. These rules mandate that any commercial property connecting to the municipal water supply install and maintain an approved backflow prevention assembly — and submit documentation proving that assembly has been tested and certified by a licensed tester. The ordinance exists to protect the public water supply from contamination that can occur when pressure differentials cause non-potable water to flow backward into the city's distribution system. Restaurants are considered a high-hazard connection category because of chemicals, grease, and biological matter present in commercial kitchen operations, which means certification requirements are strictly enforced by the Aberdeen Public Works and Utilities Department.
Operating a food service establishment in Aberdeen without a current, valid backflow prevention certification exposes your business to serious regulatory and financial consequences. The city has authority to act swiftly when a device is uncertified, untested, or found non-compliant during inspection. Consequences include:
- Water service disconnection — the city may shut off your water supply until compliance is demonstrated, forcing an immediate closure of operations
- Fines and penalties — daily fines may accrue for each day your establishment remains out of compliance; contact the Aberdeen Utilities Department to confirm current fine schedules
- Required remediation — you may be ordered to install, repair, or replace your backflow prevention assembly at your own expense before service is restored
- Permit revocation — non-compliance can jeopardize your broader operating permits, including your food service license, triggering review by the South Dakota Department of Health
- Insurance and lease implications — many commercial landlords and general liability insurers require proof of current backflow certification; a lapse can constitute a lease violation or grounds for a coverage denial in the event of a water contamination claim
Legal code: Local sewer use regulations, water connection requirements, road/sidewalk ordinances, grease discharge limits
Recent update: Aberdeen has aligned its backflow prevention testing and certification cycle with updated South Dakota Plumbing Commission guidelines that took effect in recent years, reinforcing annual testing requirements for high-hazard commercial connections — contact the Aberdeen Utilities Department to confirm whether your device classification or testing interval has changed for 2026.
Who Needs a Backflow Prevention Device Certification?
| Type | Required | Notes |
|---|---|---|
| Restaurant (Full-Service) | Required | Full-service restaurants connect directly to Aberdeen's municipal water supply for cooking, dishwashing, and ice-making, making them subject to backflow prevention requirements under South Dakota Codified Law § 34A-5 and Aberdeen's cross-connection control program administered by Aberdeen Water Treatment. |
| Bar / Nightclub | Required | Bars and nightclubs operate carbonated beverage dispensers, glass washers, and ice machines that create cross-connection hazards with the potable water supply, requiring certified backflow prevention devices per South Dakota Department of Environment and Natural Resources (DENR) cross-connection rules. |
| Food Truck | Not Required | Food trucks operating with self-contained water tanks (not directly connected to a municipal water line) are generally exempt from Aberdeen's backflow prevention device certification requirement; however, if a food truck hard-connects to a municipal water supply at a permanent commissary or event hookup, certification is required — contact Aberdeen Water Treatment to confirm your specific connection type. |
| Coffee Shop / Café | Required | Espresso machines, commercial coffee brewers, and under-counter refrigeration units create direct cross-connection risks with Aberdeen's municipal water system, requiring a certified backflow prevention assembly under South Dakota DENR plumbing and cross-connection standards. |

33 of 40 auto-filledBusiness Legal Name
textEnter the exact legal name of the business as registered with the South Dakota Secretary of State — this must match your business registration documents character-for-character, including punctuation and legal suffixes (e.g., 'LLC', 'Inc.').
COMMON MISTAKE: Entering a DBA (doing-business-as) trade name instead of the registered legal entity name is the most frequent error — for example, writing 'Aberdeen Family Diner' instead of 'Aberdeen Family Diner LLC' will trigger a mismatch with city records and delay processing.
Primary Contact Name
textEnter the full legal first and last name of the individual who will serve as the primary point of contact for the city's water department regarding this certification — this person must be reachable to schedule any required on-site inspection of the backflow prevention device.
COMMON MISTAKE: Listing a general business name or department (e.g., 'Management Office') instead of a specific individual's name will cause the application to be returned as incomplete.
Primary Contact Title
textEnter the official job title of the primary contact person listed in the previous field — use the title as it appears on business documents (e.g., 'Owner', 'General Manager', 'Facilities Manager').
COMMON MISTAKE: Leaving this field blank or entering a vague descriptor like 'Staff' instead of a recognized authority title can raise questions about whether the contact has the authority to authorize plumbing access for inspection.
Contact Phone Number
textEnter a direct, working phone number for the primary contact in standard 10-digit format (e.g., 605-555-0123) — the Aberdeen Water Department will use this number to schedule device inspections and notify you of certification status.
COMMON MISTAKE: Entering a general business line that routes to voicemail without a callback option, or using a format with extra characters (e.g., '+1 (605) 555-0123'), can delay scheduling of required inspections.
Contact Email Address
textEnter a valid, actively monitored email address for the primary contact — the city will use this address to send certification notices, renewal reminders, and any deficiency notifications regarding your backflow prevention device.
COMMON MISTAKE: Using a shared or infrequently checked email address (e.g., a generic 'info@' address) risks missing critical inspection scheduling notices or deficiency correction deadlines, which can result in a lapsed certification.
Facility Street Address
textEnter the physical street address of the facility where the backflow prevention device is installed or will be installed — this must be the location of the water service connection, not a mailing address or corporate headquarters.
COMMON MISTAKE: Entering a P.O. Box or the owner's home address instead of the restaurant's physical service address is a leading cause of rejection, as the city's water department must be able to locate and inspect the specific water connection point.
Facility City
textEnter 'Aberdeen' — this certification is issued by the City of Aberdeen Water Department and is only valid for facilities served by the Aberdeen municipal water system.
COMMON MISTAKE: Entering a neighboring municipality or county name instead of 'Aberdeen' will result in immediate rejection, as the certification is jurisdiction-specific to Aberdeen's water distribution system.
Facility State
textEnter 'SD' or 'South Dakota' — use the standard two-letter postal abbreviation to match the format expected by the Aberdeen Water Department's records system.
COMMON MISTAKE: This field is rarely a source of rejection on its own, but leaving it blank can cause automated form validation errors that flag the entire submission as incomplete.
Facility ZIP Code
textEnter the 5-digit ZIP code for the facility's physical location — Aberdeen's primary ZIP codes are 57401 and 57402; confirm yours against the USPS address lookup tool if you are unsure which applies to your specific street address.
COMMON MISTAKE: Using a ZIP+4 extended format (e.g., '57401-1234') when the form expects only 5 digits can cause a field validation error; enter only the 5-digit base ZIP code unless the form explicitly requests the extended format.
Currently Has Backflow Device Installed
checkboxCheck this box only if a backflow prevention device is already physically installed at the facility's water service connection point — if you are applying ahead of installation, leave this unchecked, as the city's inspection workflow differs depending on whether a device is already in place.
COMMON MISTAKE: Checking this box when no device is yet installed — in order to appear further along in compliance — will result in an inspection visit that finds no device, triggering a failed inspection report and potentially adding 3–4 weeks to your certification timeline while a re-inspection is scheduled.

Top 5 Backflow Prevention Device Certification Mistakes
1. Using an Unlicensed or Unregistered Tester
Aberdeen requires that all backflow prevention device tests be conducted by a tester certified by the South Dakota Department of Environment and Natural Resources (DENR) — submitting a report signed by an uncertified technician results in automatic rejection. For example, hiring a general plumber who lacks a current DENR backflow tester certification will void the entire submission, forcing you to reschedule the test and restart the review process. Verify your tester's certification number against the DENR registry before scheduling the inspection; this mistake alone can add 3–4 weeks to your timeline.
2. Submitting an Incomplete or Illegible Test Report
The City of Aberdeen requires a fully completed test report form, including device location, make, model, serial number, test kit serial number, and all gauge readings — leaving any of these fields blank is the second most common cause of rejection. A concrete example: submitting a report with the 'initial test' readings filled in but the 'final test' readings left blank will trigger a deficiency notice regardless of whether the device passed. Use Aberdeen's approved test report format and double-check that every required field contains a legible entry before filing.
3. Missing the Annual Recertification Deadline
Backflow prevention device certifications in Aberdeen must be renewed annually, and operating a food service establishment with an expired certification can result in a notice of violation from the Public Works Department. Many owners assume the city will send a reminder, but Aberdeen does not guarantee advance notice — the responsibility to track the expiration date falls entirely on the property owner or operator. Mark your renewal date at least 30 days before the anniversary of your last approved test to allow time for scheduling a certified tester and submitting paperwork; missing the deadline by even one day can trigger a compliance flag that adds 2–3 weeks to resolution.

Step 1: Contact Aberdeen Public Works or Water Department to confirm backflow prevention device certification requirements for your commercial water connection
Call Aberdeen Public Works at the main city line or visit their office to confirm whether your restaurant's water connection requires backflow prevention certification under local sewer use regulations. Ask specifically: (1) whether your facility's water volume/usage tier triggers the requirement, (2) which certified tester they recognize, and (3) whether they require annual testing records on file. Most restaurants discover they're required during this call — do not skip it or you'll install a device that doesn't meet local specs.
Step 2: Enroll in IAPMO Backflow Prevention Institute (BPI) training course offered through South Dakota Plumbing-Heating-Cooling Contractors (SDPHCC)
Register for the ASSE/ANSI Series 5000 Cross-Connection Control course through SDPHCC (the authorized provider in South Dakota) — this is the prerequisite certification for testing and maintaining backflow devices. Training is offered in-person at multiple locations across South Dakota; confirm the Aberdeen-area schedule on SDPHCC's website or call their office. Course registration typically includes a materials fee (approximately $150–$250, paid directly to SDPHCC — not a government filing fee).
Step 3: Complete the ASSE/ANSI Series 5000 Cross-Connection Control training (typically 40 hours over 5 days)
Attend the full 40-hour certification course covering backflow prevention device types, installation, testing procedures, and maintenance protocols. The course is delivered over 5 consecutive business days and includes hands-on lab work with actual devices. You must attend all sessions and take notes on testing procedures — IAPMO examiners test on practical knowledge, not just theory.

See All RequirementsProcessing timelines vary depending on the complexity of your system and inspector availability, per the Aberdeen Water Utilities Department. Most applicants should expect the inspection and certification process to take between 1–3 weeks from submission, though this can extend if the inspector identifies issues requiring system modifications. Contact Aberdeen Water Utilities to confirm the current inspection schedule for your specific location.
Government filing fees for backflow prevention device certification in Aberdeen range from $300–$600, as posted on the Aberdeen Water Utilities Department fee schedule. The final cost depends on the type and complexity of your backflow prevention system. Before submitting your application, verify the exact fee for your device type by contacting Aberdeen Water Utilities — not legal advice.
No — a backflow prevention device certification is location-specific and cannot be transferred to a new restaurant location. If you relocate your business, you will need to obtain a new certification for the backflow prevention system at your new address. You should also coordinate this requirement with your Building Permit and Certificate of Occupancy applications, as all three are typically required before opening at a new location.
Backflow prevention device certifications in Aberdeen typically require annual renewal or recertification, per Aberdeen Water Utilities Department standards. You will receive renewal notices from the city; mark your calendar for the expiration date to avoid service interruptions. Contact Aberdeen Water Utilities to confirm your specific recertification deadline and to understand what inspection steps are required for renewal.
During the inspection, the Aberdeen Water Utilities Department inspector will test your backflow prevention device to verify it meets state and local plumbing codes, checking for proper installation, functionality, and safety compliance. The inspector may also review your device's documentation and maintenance records. If your system passes inspection, you receive the certification; if issues are identified, you will be notified of required repairs — contact Aberdeen Water Utilities for details on the reinspection process. Consider also reviewing your Building Permit requirements to ensure all plumbing work is properly documented.
