Northern Manchester abstraction licensing strategy
Updated 10 July 2026
1. About the licensing strategy
This strategy sets out our approach to managing new and existing abstractions and impoundments within the Northern Manchester catchment in the North West River Basin District.
Our approach ensures that we:
- meet river basin management plan objectives for water resources activities
- avoid deterioration within this catchment
These requirements are set out by the Water Environment (Water Framework Directive) (England and Wales) Regulations 2017 (referred to as the Water Framework Directive 2017). We apply this approach to the water body in which the abstraction or impoundment is located.
It also applies to:
- all downstream surface water bodies that may be affected by any reduction in abstraction related flow
- adjacent groundwater bodies affected by any reduction in groundwater level
The strategy also sets out local approaches to the sustainable management of water resources in collaboration with partners.
Our guidance on managing water abstraction gives the technical explanation, legal and policy requirements behind the abstraction licensing strategies (ALS).
Check our guidance if you need to:
- check if you need a licence to abstract water
- check if you need a licence to impound water
- apply for an abstraction or impounding licence
We continuously update our assessment tools, because of this some details in this document, for example hands off flow (HoF) values, may be out of date. You can contact the Environment Agency for the latest data.
Collaborative and sustainable water management
Our long term goal is to develop a stronger catchment focus for water resources. We are working with abstractors and catchment groups to:
- develop local solutions to existing pressures
- to prepare for the future
Catchment groups may include a variety of different partnership groups such as:
- abstractor groups
- local catchment partnerships
- priority catchment groups
- environmental groups
Regional water resources groups are taking forward strategic multi-sector regional plans which consider environmental needs for long term planning. We are working with these groups to improve the connection between regional planning and catchment scale planning and delivery. There is more information on regional planning in the National Framework for Water Resources.
This strategy is a tool to make informed decisions on the choices abstractors make about their use of water. We want this strategy to help abstractors plan their water use and become more resilient in the face of climate change.
2. Catchment overview
2.1 Landscape and land use
The catchment area covers an area of approximately 430.7 km2. It is characterised by significant urban developments to the south associated with Greater Manchester, both residential and industrial in nature. The north of the catchment is characterised more so by agricultural land uses.
2.2 Water resources
The Northern Manchester ALS catchment covers the catchment areas for the Rivers Croal, Irwell, Roch, Irk and Medlock.
Originating in the Pennines, these rivers flow south and east towards the cities of Manchester and Salford. The River Irwell flows through the towns of Rawtenstall, Ramsbottom and Bury, while the River Croal flows through Bolton and joins the River Irwell near Farnworth. The Rivers Roch, Irk and Medlock flow through the districts of Rochdale, Heywood, Oldham and into Manchester city centre.
There is one principal groundwater aquifer in the catchment – the Manchester and East Cheshire Permo-Triassic Sandstone Aquifer – and 3 secondary groundwater aquifers, the:
- Northern Manchester Carboniferous Aquifer
- Manchester East Cheshire Carboniferous Aquifer
- Sankey and Glaze Carboniferous Aquifer
United Utilities is the only water company active in the catchment area. Water in the catchment is abstracted from surface water and groundwater sources for a wide variety of uses, including general agricultural, industry and water supply. Industry ranges from breweries and food processing, to chemicals, textiles and paper manufacture. Public water supply is mostly provided from water company owned reservoirs although other sources, such as groundwater boreholes, are also used. In the upland areas to the north and east, groundwater from springs and boreholes is used for many private domestic water supplies.
Northern Manchester features many vital reservoirs such as Greenbooth, Jumbles and Delph. These reservoirs, along with other supplies in Lancashire are known as the Pennine Sources and supplement our major public water supplies from the Lake District and Wales.
Water-based recreation is mainly limited to reservoirs or canals rather than rivers. Activities such as windsurfing, sailing and canoeing are available at locations such as Hollingworth Lake, Belmont, Clowbridge and Watergrove reservoirs. Angling is also popular in the area.
The Rochdale Canal runs through the east of the ALS to central Manchester.
2.3 Climate change
Climate change is likely to affect the quantity and seasonal availability of water resources within the catchment. The Environment Agency climate impacts tool provides a simple description of current and potential future challenges.
2.4 Partnership working
The Northern Manchester catchment partnership in this catchment:
- focus on developing collaborative approaches to water resources management and planning
- engage with stakeholders to find solutions to water scarcity within the catchment
These should bring together stakeholders from a range of backgrounds to address issues in the catchment
Map 1. Catchment overview of the Northern Manchester ALS
Map 1 shows the extent of the Northern Manchester catchment, as well as the location of the 13 assessment points and major surface water bodies in the area. The catchment extends from the upland area of the Forest of Rossendale in the north, down through Oldham in the east, across northern parts of Manchester in the south, and towards Bolton in the West. Key watercourses include the River Irwell, Naden Brook, River Roch, River Medlock, River Irk, River Croal and Bradshaw Brook. These waterbodies flow generally from the higher moorland areas in the north and east towards the lower, more urbanised areas in the south.
3. Water resource availability in the Northern Manchester catchment
3.1 Surface water availability
The method for calculating the water resource availability is explained in managing water abstraction. Water availability is calculated at selected assessment points (APs). The maps show the water availability calculated at the AP; local water availability may differ.
There are 13 APs in the Northern Manchester ALS:
- AP01 covers River Irwell at Irwell Vale gauging station
- AP02 covers River Irwell prior to confluence (ptc) River Roch
- AP03 covers River Irwell ptc River Croal
- AP04 covers River Irwell at Adelphi Weir gauging station
- AP05 covers River Croal at Farnworth gauging station
- AP06 covers River Medlock at London Rd gauging station
- AP07 covers River Irk at Collyhurst gauging station
- AP08 covers River Roch ptc River Spodden
- AP09 covers River Roch ptc Naden Brook
- AP10 covers Roch at Blackford Bridge gauging station
- AP11 covers River Spodden ptc River Roch
- AP12 covers Naden Brook ptc River Roch
- AP13 covers Bradshaw Brook
3.2 Water resource availability colours and implications for licensing
The water resource availability is calculated and the colour assigned at four different flows:
- Q30 – the flow of a river which is exceeded on average for 30% of the time, therefore you would expect the river flow to be lower than Q30 on 256 days in an average year, that is, a higher flow
- Q50 – the flow of a river which is exceeded on average 50% of the time, therefore you would expect the river flow to be lower than Q50 on 183 days in an average year
- Q70 – the flow of a river which is exceeded on average for 70% of the time, therefore you would expect the river flow to be lower than Q70 on 110 days in an average year
- Q95 – the flow of a river which is exceeded on average for 95% of the time, therefore you would expect the river flow to be lower than Q95 on 18 days in an average year, that is, a low flow
We use the colours below to represent different surface water availability at these flows:
Water available for licensing
Green
There is more water than required to meet the needs of the environment.
New licences can be considered depending on local and downstream impacts.
Restricted water available for licensing
Yellow
Full licenced flows fall below the environmental flow indicators (EFI).
If all licenced water is abstracted there will not be enough water left for the needs of the environment. No new consumptive licences would be granted. It is likely we will be taking action to reduce full licenced risks. Water may be available if you can ‘buy’ (known as licence trading) the entitlement to abstract water from an existing licence holder.
Water not available for licensing
Red
Recent actual flows are below the EFI (or have been overridden by a downstream AP where flows are below the EFI).
This scenario highlights water bodies where flows are below the indicative flow requirement to help support a healthy ecology in our rivers. We will not grant further licences in these water bodies.
We are currently taking action in these water bodies. Water may be available if you can buy (known as licence trading) the amount equivalent to recently abstracted from an existing licence holder.
There may be water available for abstraction in discharge rich catchments. You need to contact the Environment Agency to find out more.

3.4 Groundwater resource availability
Abstracting groundwater can impact on overlying surface water bodies and groundwater dependent ecosystems. This impact is measured at the surface water AP. We cannot grant new groundwater licences where abstraction is reducing flows to below the indicative flow requirement to help support a healthy ecology. This is based on Q95 flows.
We must also account for:
- the available resource in the aquifer
- the impact of abstraction on protected sites
- the risk of saline intrusion
Water availability for groundwater in this catchment is dealt with on a case-by-case basis. Contact the Greater Manchester, Merseyside and Cheshire Integrated Environmental Planning or Groundwater and Contaminated Land teams for further information relating to groundwater abstraction.
3.5 Resource reliability
If you want to apply for a licence, it is worth considering the reliability of your abstraction.
By assessing the quantity of water available at different flows it is possible to see:
- when there is a surplus or deficit of water
- the associated reliability of an abstraction
This is an indication only. Actual reliability of a licence will be discussed when you apply.
Map 7 gives an indication of the resource availability for consumptive abstraction in the Northern Manchester area expressed as a percentage of time. In this catchment:
- AP1: Consumptive abstraction is available at least 95% of the time
- AP2: Consumptive abstraction is available at least 95% of the time
- AP3: Consumptive abstraction is available at least 95% of the time
- AP4: Consumptive abstraction is available at least 95% of the time
- AP5: Consumptive abstraction is available at least 95% of the time
- AP6: Consumptive abstraction is available at least 95% of the time
- AP7: Consumptive abstraction is available at least 95% of the time
- AP8: Consumptive abstraction is available at least 30% of the time
- AP9: Consumptive abstraction is available at least 95% of the time
- AP10: Consumptive abstraction is available at least 95% of the time
- AP11: Consumptive abstraction is available at least 95% of the time
- AP12: Consumptive abstraction is available less than 30% of the time
- AP13: Consumptive abstraction is available less than 30% of the time
Map 7. Water resource reliability of the Northern Manchester ALS expressed as a percentage of time available
3.6 Other considerations for resource availability and reliability
When we grant a licence, it does not mean that we guarantee a supply of water.
We may have to add constraints to licences such as ‘hands off flow’ (HoF) or ‘hands off level’ (HoL) conditions to protect the environment and the rights of other abstractors. These conditions specify that if the flow or level in the river drops below what is needed to protect the environment, abstraction must reduce or stop. In dry years, restrictions are likely to apply more often, which will affect the reliability of supply.
Whilst this document may say that water is available for abstraction, this does not guarantee that all applications will be successful. This is because we must determine each application on its own merits, and local factors may mean we are either unable to grant a licence as applied for, or even at all.
New licences within an ALS are usually given a ‘common end date’ (CED), which allows them to be reviewed at the same time.
The next CED for this ALS is 31 March 2027 and the subsequent one is 31 March 2039.
3.7 Impoundments
Applications for impounding licences will be dealt with on a case-by-case basis and take into account the requirements of our obligations under the Conservation of Habitats and Species Regulations 2017 and Water Framework Directive 2017.
An impoundment is a dam, weir or other construction in an inland waterway that obstructs or impedes flow. Our assessment of an impounding licence application takes into consideration its potential impacts on the environment (such as fish migration), flood risk, downstream water users and flow modification. In line with current legislation, we do not time limit impounding licences.
You must have an impounding licence before you start to construct, alter, repair or remove an impounding structure, even in an emergency. However, certain exemptions may apply and if we deem there is little or no impact on the environment and other water users, you may not need a licence. Contact the Environment Agency if you intend to construct, alter, repair or remove an impounding structure so that we may advise you whether a licence is required.
There is more information in our guidance on how to check if you need a licence to impound water.
4. How we manage water availability in the Northern Manchester ALS
4.1 Surface water
We assess surface water flows at each AP, which are significant points on a river, often where two major rivers join or at a gauging station. An AP can cover multiple surface water bodies.
Where groundwater abstractions directly impact on surface water flows, the impact is measured at the surface water AP.
The information for each AP gives an indication of:
- how much water is available for further abstraction
- the associated restrictions we may have to apply to new and varied abstraction licences from the main river
Depending on the nature of the catchment, tributaries to the main river may be subject to different restrictions and quantities. This may be assessed locally on a case-by-case basis.
Each HoF is linked to an AP and is dependent on the resource availability at that AP. In some cases, additional restrictions may apply to licences where there is a more critical resource availability downstream to protect the ecological requirements of the river and other water users. This has been considered in the figures given for each AP.
All abstraction licence applications are subject to an assessment. This takes account of any local and downstream issues and may be subject to further restrictions.
The following subsections provide information for each AP in the Northern Manchester ALS area. Each subsection shows the potential reliability of a new licence expressed as the number of days water may be available under this restriction during an average year. In cases where there is water available at all flows, we may apply a minimum residual flow (MRF) equal to 75% of Q99 flows in the water body to protect very low flows. We will decide this on a case-by-case basis.

4.3 Heavily modified water bodies
Some water bodies have been designated as artificial or heavily modified if they are substantially modified or constructed to be used for water supply, urban purposes, flood protection or navigation. Many of the headwaters of the Mersey tributaries have been impounded to create reservoirs for public water supply.
Under the river basin management plan for the Northern West, private, public and voluntary and third sector organisations will work together to ensure that these water bodies can achieve their full environmental potential.
4.4 High ecological status water bodies
High ecological status water bodies are those that are close to a natural condition. We restrict abstraction in these water bodies to maintain this condition.
The Northern Manchester ALS area has one high ecological status water body:
Table 15. Summary of high ecological status water body
| Water body name | Water body ID |
|---|---|
| Astley Brook, Irwell | GB112069064560 |
4.5 Protected sites
The Conservation of Habitats and Species Regulations 2017 provides a very high level of protection to:
- Special Areas of Conservation (SAC), which contribute to biodiversity by maintaining and restoring habitats and species
- Special Protection Area (SPA), which provides protection to birds and their nests, eggs and habitats
Government policy treats Ramsar sites (internationally important wetland sites) in the same way as SACs and SPAs. Ramsar sites, SACs and SPAs are referred to collectively as European sites. Sites of Special Scientific Interest (SSSI) also carry a high level of environmental importance.
Conservation objectives are the overarching objectives for European and SSSI protected sites to maintain at, or to reach, favourable condition. These are set by Natural England. The process for setting targets that underpin these objectives is described through the Joint Nature Conservation Committee approved ‘Common Standards Monitoring Guidance’ (CSMG). Natural England use CSMG targets to assess the condition of European and SSSI protected sites. Natural England consider these quantitative targets a pre-requisite for achieving the conservation objectives for European or SSSI designated sites. We have a duty to have regard to Natural England’s advice when determining licence applications that may impact on a designated site.
We may need more detailed supporting information when a licence application could impact on a designated conservation site. This will allow us to complete the required statutory assessment.
Further information on protected sites and species can be found on Natural England’s website.

5. Managing the catchment together
5.1 Action on unsustainable abstraction
Our guidance on managing water abstraction gives details on:
- what an unsustainable abstraction is
- the measures available to resolve environmental issues caused by abstraction
We have taken a number of actions to:
- reduce abstraction
- achieve objectives in this catchment
There are a series of other actions that we are taking to address unsustainable abstraction. These include:
Revoking or reducing unused and underused licences
We are contacting abstractors who have not used their licence or have only used a small portion of their licensed volumes. We are asking if they still require the water and for what purpose. Abstractors need to provide justification for retaining their licence, such as evidence of future use, contractual agreements to supply water or planning permission. We can revoke licences or reduce volumes where there is not sufficient evidence of need.
Water Industry National Environment Programme (WINEP)
We are working with water companies to investigate and address the impact of their abstractions on the environment. The WINEP identifies the actions required. Water companies are implementing changes through the Asset Management Plan (AMP) process. For example:
- river restoration
- capping of licences
- river augmentation
Managing time limited licence (TLL) renewals
We are managing TLL renewals to ensure abstraction is not having a negative impact on the environment now or in the future.
Managing licence variations
We are managing licence variations to ensure abstraction is not having a negative impact on the environment now or in the future. There is more information on our groundwater licence variation policy later in this section.
Water efficiency measures
We encourage forward planning and water efficiency measures to prepare for peak demand periods. At times of limited resource, we engage with spray irrigators and encourage them to use water as efficiently as possible. We also promote night-time irrigation whenever possible to reduce evaporative losses.
Voluntary restrictions
We use voluntary restrictions to reduce demand and prevent or delay formal licence restrictions.
Storage reservoirs
We support and encourage licencing for storage reservoirs which are filled by winter high flows when water is available.
Managing renewals or variations of licences
We have and will continue to change surface water and groundwater licences by reviewing time limited licences.
We will adjust licence quantities as necessary if:
- abstraction quantities are no longer justified
- renewal may pose a risk of deterioration in ecological status
This may be by capping of licence quantities when they have come up for renewal as part of the renewal process.
Surface water licenses
Licence renewals will be on the following broad principles around environmental sustainability.
As a minimum, all surface water licences will need a HoF to protect the ecological needs of a river at low flows. We define low flows as the Q95, which is the amount of flow in a river that is exceeded 95% of the time. To calculate the amount of water required to support the ecology of a river at low flows we use a tool called the Environmental Flow Indicator (EFI).
We will renew an application on the same terms, subject to it having a HoF condition that protects low flows. We will renew to the relevant CED. There must be no other sustainability issues in the surface water bodies influenced by the abstraction. The applicant must justify the quantities and demonstrate that the water is being used efficiently.
Groundwater licenses
Licences will be renewed on the following broad principles around environmental sustainability.
We will consider renewing the licence at the same quantities if the following requirements can be met:
- the aquifer
- overlying rivers
- associated wetland habitats
These must be met at current levels of abstraction and if all licenced water is abstracted.
We will reduce the licenced quantities if there is a risk that abstracting all the licenced water could impact on the ecology.
We will look at the impact of TLLs on an individual basis and will consider renewal of TLLs with regard to:
- environmental sustainability
- justification of need
- efficient use of water
We must ensure that the licensing of abstraction:
- is sustainable
- will not cause deterioration in the ecology of our rivers, wetlands and estuaries
- will not deplete groundwater resources
Trading and aggregation
If unconstrained, water rights trading could result in a rise in annual average abstraction increasing the risk of deterioration in water body status. Section 5.3 gives more information on our approach to trading in Northern Manchester.
Aggregation could also result in deterioration. It will involve similar restrictions as water rights trading. Aggregation could include:
- adding a new point of abstraction to the licence (subject to local assessment)
- adding an additional purpose to a licence
- combining multiple licences
5.2 Approaches to sustainable water management
We have undertaken a range of catchment focused initiatives. This section outlines options initiated in this catchment for future approaches to water management, including collaboration and sharing which may be of interest to both new and existing abstractors.
Unused licence project
As part of a national campaign to address non-public water supply over abstraction, 92 licence holders were contacted who had not used or had underused their abstraction licences from 2012 to 2018 in the Greater Manchester, Merseyside and Cheshire (GMMC) area. A total of 17 licences were revoked (16 voluntarily). These efforts resulted in the recovery of 1.3 million cubic metres of water per year from unused licence revocations.
5.3 Water rights trading
We want to make it easier to trade water rights. A water rights trade is where a person sells all or part of their water right, as defined by their abstraction licences, to another person on a permanent or temporary basis. In many cases a trade will involve a change in abstraction location or use which we will need to approve through the issue or variation of abstraction licences.
In licensing trades, as with new abstraction licences, we need to make sure that we do not cause any deterioration in water body status within the water bodies where the trade will take place and to downstream water bodies.
If you want to trade water, you can get enhanced (paid for) advice. This will help identify the amount of water available and conditions likely to be added to any licence granted, for example a HoF condition to protect the environment during periods of low flow.
Opportunities for trading will depend on local operating agreements and local management.
To find out more about licence trading, use our guidance on trading water abstraction rights.
6. Glossary

Abstraction licence: The authorisation granted by the Environment Agency to allow the removal of water.
Assessment point: A significant point on a river, often where two major rivers join or at a gauging station.
Catchment: The area from which precipitation and groundwater will collect and contribute to the flow of a specific river.
Catchment based approach: Partnership working at the river catchment scale to deliver a range of environmental, social, and economic benefits while protecting our precious water environments for the benefit of all.
Consumptive abstraction: Abstraction where a proportion of the water is not returned either directly or indirectly to the source of supply after use. For example, for the use of spray irrigation, general agriculture, domestic use, public water supply and water bottling.
Discharge: The release of substances (for example, water, treated sewage effluent) into surface waters.
Environmental flow indicator: Flow indicator to prevent environmental deterioration of rivers, set in line with new UK standards set by UK Technical Advisory Group.
