Water Management Planning Guidance for Construction Projects


head Local-Catchment-Situation

The national environmental regulators are responsible for managing water resources in England and Wales, and SEPA in Scotland, on behalf of the UK Government/Scottish Parliament.

One role of the national environmental regulators (NERs) is to develop Catchment Abstraction Management Strategies (CAMS). These provide an assessment of the amount of water available in each river catchment. As part of this work the NER’s periodically review all abstraction licences to determine whether or not they are having an unsustainable impact on the environment.

During a drought, the NERs step up their monitoring actions to make sure that they continue to protect the environment from harm and take action to protect the environment. It is therefore useful for site managers to be aware of the local catchment situation, so that in times of extreme circumstance they are aware if they may be affected by emergency actions such as restrictions on abstraction due to drought orders.

To identify which river basin district and catchment your site is located in, maps can be found at

Relevant catchment abstraction management strategy documents which outline the water scarcity situation and pressures on resources can be found at

The risk of flooding in the local area both for the site and for critical routes to site should be considered. Information on flood risk, including interactive maps, can be found on the national environmental regulators websites, for example;

The flood risk of the area should be taken into consideration and a flood plan developed if required to ensure site resilience. The site manager should be made aware of the risk of flooding to the site. If a flood plan has been prepared the site manager should own this document whilst the site is active. Ideally the flood prevention measures and emergency arrangements should a flood event occur should be contained within the site emergency procedures, where health and safety of persons working or present on the site is prioritised and business resilience also a consideration. Business resilience is the positive ability of a system or company to adapt under challenging conditions.

In areas of high flood risk a free service called Floodline Warnings Direct is operated by the national environmental regulators. Warnings can be provided via telephone, mobile, email, SMS text message and fax. You can sign up for this service at

If the site has been located in an area of flood risk it is likely that the construction has included flood prevention or alleviation as part of the construction methodology. Details of maintenance or operation of these facilities should be handed over to the site owner upon completion, and documents may be required to be sent to planning officers to discharge key conditions.
