If you own or operate a large raised reservoir you must report any reservoir safety incident by law if:

• an uncontrolled release of water occurred, or could have occurred
• you took emergency measures to stop it happening or worsening

You must send a preliminary incident report to us as soon as possible. Use to do this.

You have 12 months to investigate the causes and impacts of the incident and identify any lessons learned. You must send a final incident report with these learnings. Use to do this.

If you have not completed your investigations within 12 months you must update us before the deadline.

Tell us:

• what activities you have done
• your expected finish date

You should then send once you have finished your review.

These forms help you fill in the information we need. Use as much detail as you think is appropriate. You may find it useful to ask a qualified civil engineer to help with your form.

We encourage you to report your incident even if it:

• does not meet the above criteria
• occurred at a small raised reservoir

These lessons can help to prevent similar events happening where more serious consequences may occur.

What a reservoir incident is

The following definitions may help you understand what we mean by a 鈥榬eservoir incident鈥�.

Incident

An unplanned event which resulted in an uncontrolled or unintentional release of water, or damage to the site.

This could include a failure, or partial failure of any:

• dam
• wall
• embankment
• other water retaining structure

An unplanned event which resulted in one or more of the following:

• damage to the reservoir structure which may affect its safety
• an unintentional release of water resulting in negative impacts downstream such as flooding or physical damage
• emergency or precautionary measures being taken to stop the event worsening

• corrective action聽
• timely intervention聽

You may also use this category to report any unplanned or unexpected event from which wider learning can be gained.聽

Defects being addressed as measures in the interest of safety are reported and monitored through the inspection process. You should not record these as incidents or near misses.

Minor defects picked up and rectified as part of routine maintenance are not required to be reported. You may choose to do so if there is particular learning which may interest the industry.

Further information聽聽

There is important learning to be made from incidents. We share this learning to help reduce the risk of these events happening elsewhere. The information in your forms will be shared with the reservoir industry with any identifiable information removed to ensure anonymity.聽聽
