Backflow Prevention and Cross Connection Control Program

The Drinking Water Branch’s Permit Program protects the public health by reviewing, tracking, and requesting additional information; and issuing or denying for permits submitted by a public water system. The common permits that get requested are the General Construction Permit 327 IAC 8-3.5 [PDF] known also as Notice of Intent (NOI) and Individual Construction Permits. Additionally, the Permits Staff oversees the implementation of Indiana’s Cross Connection Control and Backflow Prevention Program.

Please note that 327 IAC 8-3 [PDF] states that no person shall cause or allow the construction, installation, or modification of any facility, equipment, or device for any public water system without having a valid construction permit issued by the commissioner, except for replacement of equipment of similar design and capacity, none of which will influence plant operation; a system’s hydraulic design or waste products; or the water distribution system design, operation, or capacity.

Notice of Intent - Individual Construction Permits – Water Main Extension

A General Construction Permit or NOI are requests to do main extension projects in the water distribution system. These NOI’s are important because it extends water lines out to areas of industrial parks and subdivisions so that these remote places are able to have water. The "Notice of Intent to Construct a Water Main Extension – 49008" (available on the IDEM Forms page). This form includes instructions on how to complete the form, and how to make electronic payment and submission. If this form is not completed or if the project does not meet the eligibility criteria, the public water system is notified in writing that the project is not approved. If IDEM does not notify the public water system within 30 days with regards to necessary corrections, then the system can go ahead and begin construction of the water main extension immediately after the 30th day.

Applicants will now need to verify whether the customer is designated a cross connection hazard in accordance with 327 IAC 8-10-4(c), and if so, confirm that the appropriate backflow protection will be installed at the service connection. Once we are notified that these projects are completed, an inspection is done to make sure the system followed all appropriate guidelines to provide safe and sufficient amount of water to their new customers.

New System Construction Permit

All new community and nontransient noncommunity drinking water systems in Indiana are required to complete to things prior to any construction being done at the proposed site. The first item to complete is a well site survey, which helps systems identify the best locations to construct a new well. The second, is for a proposed system to submit a Water System Management Plan (WSMP) that defines a proposed system’s technical, managerial, and financial capacity to operator sustainably. The Information Handbook for Preparing a Water System Management Plan [PDF] is a great tool in guiding new projects to meet state standards. Additional information on the WSMP, is available in the “New System Requirements – Water System Management Plan” section on the Capacity Development Program page.

Backflow Prevention and Cross Connection Control Program

The Backflow Prevention and Cross Connection Control Program establishes reasonable guidelines and regulations to ensure that public water systems develop an effective Cross Connection Control Program for their entire system. This program requires customers of public water systems to install backflow prevention devices as well as having these devices tested at a minimum of once a year as required in 327 IAC 8-10 [PDF]. These results should be reported on the “Backflow Device Test Form – 55788” (available on the IDEM Forms page). The completed form must be submitted in the method required by the public water system to both customer and the public water system within 30 days of the test being completed. This form, nor any backflow test form, should not be sent to IDEM, unless specifically requested by IDEM.

IDEM’s Cross Connection Control and Backflow Prevention Manual [PDF] is an excellent resource for public water systems, backflow testers and homeowners on what a cross connection program entails as well as why such a program is necessary. The manual was revised in July 2016 in order to provide regulated communities (public water systems), plumbers, irrigation contractors, industrial facilities, etc. with the most up to date information regarding general guidelines for developing cross-connection control and backflow prevention in the State of Indiana. Also incorporated in the 2016 Edition are the revised rules that went into effect on December 13, 2012, a sample cross connection control ordinance, the state Backflow Device Test Form, clarification on the cross connection rules in the Indiana Plumbing Code, and clarification on the exemptions within the IDEM rule. In addition to IDEM rule, we have included in this manual sections of the Indiana Administrative Codes, as administered by other state agencies such as Indiana State Department of Health and Department of Fire and Building Services (Uniform Plumbing Code), which address cross connection hazards that may exist within their regulated communities.

Backflow Schools and Licensed Testers

IDEM maintains a list of licensed backflow testers that are Registered Cross Connection Control Device Inspectors for Indiana [PDF]. If you are interested in becoming a licensed backflow testers, you must pass a 40 hour course at one of the four providers approved by IDEM:
