Board's Area

The Board's Area includes some of the most important environmental assets and wonderful habitat in the world and some of the finest grazing land in the country. The area is home to around 50,000 people, a thriving local economy and a hugely popular tourist destination that attracts visitors from around the globe. The area is both locally and internationally important and worth the cost of defending and protecting, now and in future.


Although the entire area is at considerable theoretical risk of river flooding and inundation from the sea, the actual risk is substantially reduced by the work that we do in partnership with Local Authorities, the Environment Agency and Natural England.


The Board’s Drainage District does not extend to its full catchment area, which means that we find it more difficult to control development and flows coming into the District than we would do if we had jurisdiction over our full catchment area. The Board’s boundary is based on the principles of the Medway Letter established in 1933, which in our view needs to be changed so that we can provide an even better service.

Board's Drainage System

The Board's drainage and water level management infrastructure consists of watercourses, pumping stations and a number of other water level control structures. Our infrastructure can be viewed and downloaded from the maps available on our website – just click on the page number that you want. Detailed listings and photographs are also available by clicking on the link shown on our Board's Area webpage.


Not all of the defences within our Drainage District are controlled by the Board – the Environment Agency look after the Main Rivers and Coastal Defences. We have permissive powers to manage the other infrastructure in our Drainage District.

The Board actively maintains only the most critical watercourses that are not Main River, which equates to around 25% of the total length of watercourse in the Drainage District. It is therefore vitally important that these critical watercourses are regularly maintained to design levels, to properly convey flows to the pumps and other water level control structures.

Clearly it is equally as important to properly maintain the pumping stations and other structures that control the movement of water through the drainage channels. However, the efficiency of our systems and therefore the safety, security and well being of those living and working within our Drainage District is WHOLLY DEPENDENT upon the ENVIRONMENT AGENCY maintaining the Main Rivers and Coastal Defences.

Vision and Mission

Our Vision is to make the Drainage District and water catchment a safe place to live, work, learn and have fun, as a model of sustainable living in a flood risk area. Our Mission is to REDUCE the FLOOD RISK to people, property and the natural environment by providing and MAINTAINING technically, environmentally and economically sustainable flood defences, by enabling and facilitating land use for commercial, recreational and environmental purposes, by guiding and regulating activities in and alongside watercourses and discouraging inappropriate development in areas at risk from flooding, and by nurturing, enhancing and maintaining the natural habitats, which exist in and alongside watercourses.


Policy Statement

Our policy statement sets out the standards of protection we aspire to provide and how we will go about managing flood risk and water levels and delivering services in our area. The policy statement can be viewed and downloaded from our website.



We are able to draw on the local knowledge and experience of 39 Board Members who give their time freely to serve you, as custodians of our lowland environment. As a member of the WMA we have access to 49 employees in total together with the Board's 22 Pump Attendants. For more information please visit our Organisation webpage.



The Board provides leadership within a framework of prudent and effective controls, which enables risk to be properly assessed and managed. The Board sets the strategic aims, ensures that the necessary financial and human resources are in place to meet its objectives, and reviews management performance. The Board also sets values and standards, and ensures that the obligations to its stakeholders are understood and delivered. We have put in place a number of plans, policies, procedures and other governance arrangements to ensure best value, probity, propriety and transparency in the decision making process. The Board’s policies can all be viewed and downloaded from our website.


Drainage Rates and Special Levies

We have two primary sources of Income: the direct rating of all agricultural land and buildings and special levy payments received from Local Authorities, which reflect the extent of other property in the Drainage District. The Board sets the rate and special levies each year based on an estimate of its net expenditure, which can be viewed and downloaded from our website. Our policy is to limit any increases to the Consumer Price Index, as indicated by the Office for National Statistics for October every year.



Necessary capital improvement works and regular maintenance of the drainage infrastructure are vitally important services that we provide to help keep Broads Internal Drainage District safe. All of our operations are controlled and financed by the Board directly. We undertake planned maintenance and capital work annually, using a healthy mix of in-house resource and contractors. We also undertake rechargeable work on behalf of riparian owners and other occupiers. We respond to emergency situations and other events as and when they arise, in accordance with the Board’s emergency procedures and scheme of delegation. For more information please visit our Operations webpage.



We provide an emergency service, the extent of which appears to be largely unrecognised. We respond to emergencies during periods of high rainfall and during tidal surge events, utilising our workforce, board membership and state of the art telemetry system. We work closely with other operating authorities and Member Boards in the WMA. We have detailed how we shall respond in an emergency situation on our Emergencies webpage.



One of the principle services that we provide is regulating, controlling and facilitating development to secure the efficient working of the drainage system now and in the future. This is done by reasonable application of the Board's Byelaws and the Land Drainage Act 1991, and by working closely with the Developers, Local Authorities, Environment Agency and other Stakeholders.


Board Members

The Board has a total of 39 members who collectively make the key decisions, 19 of which are elected by occupiers of agricultural land who pay Drainage Rates directly for the services they receive (the elected members), and 20 members are appointed by the constituent Councils to represent the extent of other interests in the Drainage District (the appointed members). The current list of Board Members and the entitlement of each constituent Council can be viewed and downloaded from our website.


Board Meetings

The Board meets at least 4 times a year in Great Yarmouth. All Board meetings are public meetings and as such members of the public are welcome to attend. Scheduled meeting dates are listed on the Board Meetings page on our website. The confirmed minutes of every Board meeting and the attendance register can also be viewed and downloaded from this webpage.


Financial Statements

As a public body, the Board publishes its financial statements for the year in the prescribed format well before the statutory deadline. The Accounts are then audited by the Audit Commission’s appointed auditor and when they have provided their opinion, both the financial statements and opinion can be viewed and downloaded from our website.



Elections for membership of the Board are held every 3 years, so if you’re not happy with our performance you have the opportunity to do something about it, either by exercising your vote as a ratepayer or standing for election yourself. For more information please visit our Elections webpage.



The Board and its predecessors have been very successful in reducing flood risk, with a pedigree of over 75 years in the business. So successful in fact, that many people living and working in the area know nothing of the Internal Drainage Board and the vital work that we do to help prevent flooding and facilitate land use. Our success is inevitably measured by what does not happen rather than what does happen, which means that if flooding does not occur frequently then the value of what we do is sometimes questioned. But it is precisely because we continually maintain, improve and watch over the drainage system that we are actually able to reduce the risk of flooding. For more information please visit our history webpage.
