EXECUTIVE SUMMARY
Background to research
This report responds to a CREW call down request submitted by Scottish Government. The
aim is to review the economics of sustainable land management measures in catchments
where abstraction for the provision of drinking water takes place.
Objectives of research
The objectives are to:
(i) Collate and review existing evidence from catchment management projects that
are taking place between UK water companies and a range of partners.
(ii) Provide information on the comparative costs of drinking water treatment with
and without sustainable land management measures, and
(iii) Present information on indirect costs and/ or benefits of sustainable land
management, for example in relation to carbon storage, habitat provision and
amenity value.
Key findings and recommendations
Water companies are not able to share data needed to assess the comparative costs of
drinking water treatment with and without sustainable land management measures, as this
information could potentially give competitors an advantage. We conclude that the
commercially confidential nature of water treatment costs mean it is not currently possible to
make direct comparisons of the costs and benefits to water treatments using sustainable
land management measures. We also conclude that:
Despite this, the available evidence suggests that these measures are valuable to
water companies and to improving water quality more generally because of the range
of economic, social, environmental benefits that are produced.
The early stage of many of the projects reviewed means that measuring the
comparative costs of drinking water treatment with and without sustainable land
management measures is still in development.
Restoring peatlands is known to improve water quality and reduce water treatment
costs. Early intervention to restore damaged peatlands further increases cost-
effectiveness.
Investing in sustainable land management measures leads to wider benefits, both
tangible (e.g. carbon sink through afforestation) and non-tangible (e.g. the provision
of desirable habitats and recreational places).
Based on these conclusions, we recommend that:
1. A mechanism is needed to allow water companies’ data on water treatment to be used to
assess the cost-effectiveness of their investments in sustainable land management
measures. We understand that transparency of data does not fit with commercially sensitive
information. We suggest that:
o Water companies should report information to the Water Industry Commission for
Scotland, and Ofwat in England and Wales, so that this information can be used to
Page | 2
evaluate current sustainable land management initiatives and help provide evidence
to shape future water management policy.
2. A method of data collection is needed to ensure future comprehensive cost-benefit
analysis of sustainable land management measures. We suggest that:
o Baseline assessments of environmental status, including water quality and
biodiversity, are made before measures are implemented
o A monitoring strategy is implemented to compare water quality and wider
environmental factors including biodiversity, at appropriate stages of implementation
o Cost benefit analysis should include the tangible and intangible costs and benefits to
water consumers and to society more generally.
Policy implications
There is interest in the use of ‘sustainable catchment management’ to address pollutants
that impact on water resources used for drinking water supply. Our review shows that water
companies are increasingly investing in these measures. The Water Industry Commission
for Scotland (WICS, 2013:14) has stated:
‘We think that in future Scottish Water should have greater opportunities to
consider alternative, more innovative solutions for new investment, even if these
span numerous regulatory control periods. Although these can require greater
collaboration, and may take longer to be delivered, they are often in the best
interests of customers and the environment. This is particularly the case when
factors such as the overall carbon impact are taken into account’.
Given that land management measures are being seen as a sustainable alternative to water
treatment, and are being put into practice in Scotland, it is vital that these measures are
evaluated. Scottish Government and its agencies need access to the most up to date
information regarding the cost-benefit analysis of sustainable land management features in
order to achieve these solutions.
Research undertaken
We reviewed literature on economic assessment of environmental quality to understand
current approaches to cost-benefit analysis in this area. Much of the information was found
within the grey literature (reports, water company web pages) and highlighted a number of
UK projects involving water companies in sustainable land management measures. We
summarised each initiative in terms of aims, partners, measures used and available cost-
benefit information. We contacted key informants from water companies and NGOs involved
in these projects to check for additional unpublished information.

1.0 INTRODUCTION
This report responds to a CREW call down request submitted by Scottish Government to
review the economics of sustainable land management measures in catchments used for
drinking water abstraction. The research investigated existing catchment projects to provide
information on costs compared to treatment regimes, and evidence on indirect costs and / or
benefits of sustainable land management. Objectives were to:
(i) Collate and review existing evidence from catchment management projects that
are taking place between UK water companies and a range of partners.
(ii) Provide information on the comparative costs of drinking water treatment with and
without sustainable land management measures, and
(iii) Present information on indirect costs and/ or benefits of sustainable land
management, for example in relation to carbon storage, habitat provision and
amenity value.
1.1. Sustainable land management measures
One of the biggest threats to achieving good water quality status is diffuse pollution, i.e.
contamination that comes from many small and/or scattered sources (SEPA 2010). The
National Audit Office estimated the cumulative cost of water pollution in England and Wales at
between £700 million and £1.3 billion a year (Ofwat, 2011).
The quality of waters within a catchment closely reflects a wide range of natural processes
and human activities which occur throughout the entire catchment (SNH, 2010). Agriculture,
forestry and land use change all affect water resources; different land uses absorb differing
levels of rainfall, in turn affecting the amount of water reaching aquifers, streams and rivers.
Sustainable land management measures are a wide range of features that can be
implemented at the farm/land level to improve water quality in catchments. Table 1 sets out a
list of features and associated benefits. Please note this table is an illustrative example, not an
exhaustive list.

Conventional water treatment to remove unwanted contaminants, such as pesticides and
nutrients, are costly in terms of both energy and money. Implementing sustainable land
management measures in drinking water catchments can minimise the entry of pollutants into
water, which has potential to reduce costs at water treatment works. Installation and
maintenance of these measures often incur a cost, but prevention is increasingly asserted to
be economically cheaper than treating polluted water.
1.2. Regulatory framework
It is only recently, that water companes in the UK have been involved in sustainable land
managment measures in the catchments in which they work. Before 2010 there was no
authority for such schemes to be financed by water companies in the UK (RSPB, 2010). The
current period of water company investment (2010-2015) includes approval from water
regulators (Ofwat; Water Industry Commission for Scotland) for water companies operating in
the UK to invest in catchment management schemes, including sustainable land management
measures.
Page | 5
Using these measures to counter rising costs was initially driven by recognition of increasing
problems with pesticides and solvents in the water supply. These problems were revealed by
the introduction of monitoring requirements under the EU drinking water qualiy regulations
(1989). Identification of these problems led to a ‘step change’ in water treatment costs, which
were further increased by subsequent regulatory drivers of water quality, particularly the
European Water Framework Directive 2000 (UKWIR, 2004).
Additional drivers for catchment quality monitoring include the UK’s obligations as signatories
of the UN Convention on Biodiversity 1992, the European Bird and Habitat Directives, and the
Climate Change Acts of 2008 (UK) and 2009 (Scotland).
1.3. Water treatment costs and benefits
The Water Industry Commission for Scotland (WICS, 2012) report that £60m of the £125m
total operating costs, and £143m of the £250m total capital costs for Scottish Water in 2007-8
water were for treatment costs.
Scottish Water has estimated that in a large drinking water catchment, implementing
sustainable land management measures could save upwards of £10m over 25 years.
Implementation of such measures to protect drinking water sources can reduce operational
expenditure due to lower levels of treatment being required and can save capital expenditure
when additional treatment steps are avoided (Scottish Government, 2012).
It is widely recognised that monitoring of alternatives to intensive water treatment is needed to
understand the benefits that accrue from these, and to identify whether cost savings are being
made (Natural England, 2012; RSPB, 2010; Ofwat, 2010).
1.4. Measuring costs and benefits of sustainable land management features
The Water Framework Directive prescribes that action to reach desired quality water
standards should be taken only if the benefits outweigh the costs. This is often determined by
a cost benefit analysis. This technique is capable of measuring benefits that sustainable land
management features may bring that have a market value (such as carbon). However, it is
increasingly recognised that non-market benefits such as wildlife habitat, climate change
adaptation and improved amenity value ought to be included to properly assess the value of
water (Martin-Ortega et al, 2013).
The Water Resources (Scotland) Act 2013 places a duty on Scottish Ministers and Scottish
Water to develop the value of Scotland’s water resources, in ways that are compatible with
sustainable use of these resources. The Act prescribes that the ‘value’ of water consists of:
the value of the resources on any basis (including their monetary and non-monetary
worth), and
the economic, social, environmental or other benefit deriving from the use of the
resources (or any activities relating to them).

2.0 UK WATER COMPANIES AND CATCHMENT MANAGEMENT PROJECTS
Information from existing catchment projects which include partner water companies is set out
below. For each project we provide a brief description of the project; why and how it was
implemented; and the findings of any economic evaluation of the comparative costs of drinking
water treatment with and without sustainable land management measures and the costs and/
or benefits of these measures.
We found it difficult to gather information on the comparative costs and benefits (tangible and
intangible) of water treatments costs using sustainable land use measures for a number of
reasons:
Data are not shared by water companies
Scientific data and modelling are expensive and limited
There are limited data about how human use varies with ecosystem health
There is limited understanding of non-monetary valuation of benefits
There are a number of time lags involved
Impact of a measure depends on many different factors within a catchment, for
example a broad range of human and environmental factors.
2.1 SCaMP (Sustainable Catchment Management Programme)
SCaMP is a partnership between United Utilities and RSPB which has a 60 year lifespan
(2007-2067). The partnership aims to apply an integrated approach to catchment
management to protect and improve water quality and to deliver a range of other public
benefits, such as improved habitat condition and biodiversity and enhanced landscape value
and recreational experience. United Utilities owns 56,385 hectares of land in North West
England, and extracts drinking water for 7 million people from this area (United Utilities,
SCaMP web pages).
The main problems which affect water quality are agricultural activities and drainage of
the uplands, which has led to peat bogs drying out and erosion releasing colour and
sediment into watercourses.
The project works with farm tenants and partners including Natural England and the
Forestry Commission to carry out a number of catchment improvements strategies,
such as moorland and hay meadows restoration, establishing new woodlands,
stabilising land through scrub planting and providing new farm buildings for indoor
wintering of livestock and for lambing (United Utilities, ScaMP Solution web pages).
The scheme worked by providing farmers with income for 10 years to cover the costs
of the work.
There have been some assessments of the costs and benefits of the land management work
undertaken in this project. Undamaged moorland habitat is estimated to be worth £304/ha/yr
(UK National Ecosystem Assessment, 2011). Assuming that the project will restore habitats,
then this would provide 50% of the way towards restoring the original undamaged condition
over 40 years, so improvements are estimated to deliver benefits worth £152/ha/yr by 2047. In
Page | 7
addition, the project aims to plant 56 ha of new woodland valued at £180/ha/yr after 60 years
(Snow, 2012)
2.2 Sustainable Land Management Incentive Scheme (Scottish Water)
Scottish Water’s Sustainable Land Management Incentive Scheme is a catchment
management project aimed at improving water quality in river catchments to reduce water
treatment costs. The scheme is working in 6 Scottish catchments- River Ugie; River Deveron;
Loch of Lintrathen; Loch Ascog; Lochgoin/Craigendunton Reservoir; and Dumfries Basin
Aquifer. The approach being used in the scheme is aligned with the stated objective within the
Water Framework Directive-“No deterioration of drinking water sources”.
Specific problems have been identified in these catchments, and investment is to
address problems with pesticides, nutrients, nitrate, and dissolved organic carbon
(colour) through a wide range of eligible measures (Scottish Water, 2011).
The scheme makes payments to land owners and farmers for carrying out actions on
their land with the aim of reducing diffuse pollution of water.
Measures that can be funded include: whole farm diffuse pollution management advice
and technical support; installation of a biobed (a pit lined with compost, soil and straw
to collect, retain and degrade pesticide residues in washings from pesticide handling
activities); stock fencing and livestock watering; and naturalisation of body morphology.
Scottish Water funds up to 100% of the costs of implementing approved measures, up to a
maximum of £20,000 per agricultural business. The best practice incentive scheme is still
developing, and Scottish Water are currently (summer 2013) publicising it at agricultural
events across Scotland. The main benefit from the scheme relates to clean and safe drinking
water (Martin-Ortega et al., 2013).
2.3 Upstream Thinking (South West Water/ West Country Rivers Trust)
South West Water is working with the Westcountry Rivers Trust, and a range of organisations
to deliver sustainable land management measures across Devon, Cornwall and West
Somerset. This project follows on from a successful pilot to restore peatlands on Exmoor.
South West Water provides services in Cornwall and Devon and some areas of Dorset and
Somerset (South West Water, Upstream Thinking web pages).
Upstream Thinking has restored wetlands
The project involved working with farmers to provide them with funding to implement
practices which improve water quality
South West Water (2012:10) envisage that the investment of £9.1m in Upstream Thinking
between 2010 and 2015 will avoid the need for capital investment to upgrade treatment works,
as well as reduce the costs of energy- and chemical-intensive processes of water treatment.
The benefit: cost ratio is estimated at 65:1 over 30 years; costing 65p per customer over the
five year period.

2.4 Natural England Upland Ecosystem Pilots
United Utilities, Yorkshire Water and South West Water are in partnership with Natural
England to deliver sustainable land management measures in three upland pilot areas: South
Pennines NCA, Yorkshire; Bassenthwaite Lake catchment, Cumbria; and Dartmoor and
Exmoor, South West (Waters et al, 2012). Both the Cumbrian and South West catchments are
in national parks.
Each of the three pilot projects is targeting water quality issues (colour, turbidity,
sediments, pathogens or pesticides).
The Bassenthwaite and South Pennines pilots both produced integrated map-based
delivery plans, consisting of an opportunity map for each land management action,
outlining “what”, “where” and “how” land management action will be undertaken,
including how this can fit with farm businesses.
The South West pilot adopted a farmer led approach through Dartmoor Farming
Futures and working with individual farmers around the Wimbleball Reservoir, on
Exmoor.
Due to limited time and resources by project staff, economic evaluation was only carried out in
the South Pennines, where a marginal valuation of two scenarios was undertaken for a water
supply catchment. This showed that, even with high management costs and only valuing a
limited suite of benefits (water quality, carbon and biodiversity), investment in the catchment
was worthwhile in economic terms.
2.5 Wessex Water Catchment Management
Since 2005, Wessex Water has been working with farmers and land managers who own the
land in its water supply catchments in the south west of England. Wessex Water supplies 1.3
million customers with drinking water, and most water supplied is from groundwater sources
(Wessex Water, 2011).
Catchment advisers work in 15 catchments that are at risk of failure due to
contamination from pesticides and nitrate.
Financial assistance for farmers to change their practice is assessed on a case-by-
case basis.
Wessex Water report that the actual cost benefit ratio varies across sites, but estimate that
implementing catchment management schemes, on average, cost one-sixth of the cost of the
treatment alternative. Cost comparisons carried out by Wessex Water across 11 of their
catchments indicates that sustainable land management measures are more suited to small
rather than large catchments (Wessex Water, 2011).

2.6 Yorkshire Water Biodiversity Strategy
Yorkshire Water are working in the Don catchment during the period 2010-2015, taking a
holistic approach that involves both engineering solutions and investigating the complex
issues affecting water quality and biodiversity in the river system (Yorkshire Water, 2012). The
main aim is to address problems of colour and metaldehyde to improve water quality and
reduce reliance on energy and chemically intensive treatment processes.
Yorkshire Water (2013) report previous success in enhancing biodiversity:
habitat management at Tophill Low Nature Reserve;
re-introducing red kites to Yorkshire;
river management to increase brown trout populations in Ingbirchworth Dike (fencing to
reduce erosion), Wyming Brook (flow management), and Rivelin Dam (reservoir
release regime trials to ascertain optimal conditions);
moorland restoration (grip blocking, molinia reversion, fencing, and bracken control)
Benefits include moorland agreement to restore 99% of SSSI land; habitat improvements for a
range of birds, fish, reptiles, plants and dragonflies; and successful release of red kites, which
has produced 430 young birds in the area since 1999.
2.7 Northern Ireland Water/RSPB
Northern Ireland (NI) Water is working with a number of statutory and non-governmental
bodies to develop and deliver the Sustainable Catchment Management Area Programme for
Northern Ireland (SCAMP NI). NI Water owns approximately 8,615 hectares of land over
5,182 sites within Northern Ireland and extracts water from a variety of environments (RSPB,
2013).
NI Water has introduced SCAMP NI to protect or improve raw water quality, reliability of water
supply and quantity, and reduce the risks to these.
The focus of the project is on:
Blanket bog restoration
Wildfire prevention
Woodland creation
Heathland management
Land management
Invasive species management (Butler, 2011)
Other benefits envisaged from SCAMP NI are biodiversity in its landholdings, sustainably
improved raw water resources, protection against low flows avoiding abstraction restrictions,
and adaption to, and mitigation against, climate change.

2.8 Other sustainable land management projects
There are many examples of catchment management projects in the UK and elsewhere that
have implemented sustainable land management measures, although these are not initiatives
by water companies. We include SuRCaSE here to illustrate the potential of such projects for
future research.
Sustainable River Catchments in the South East (SuRCaSE) is a three-year project funded by
the European Union's Life Environment Programme. The project is designed to demonstrate
the value and practicalities of applying the ecosystem approach to achieve sustainable
management of water resources. The project has a number of partners, including two water
companies (Southern Water; South East Water) and promoted catchment-sensitive farming
practices in three catchments (SuRCaSE, 2009).
The project addressed four sustainable development challenges: diffuse pollution;
sustainable drainage water efficiency; improving access and amenity to the waterside
environment.
Management plans were developed for individual landowners, which advised on issues
such as the application of fertilisers and best practice in pesticide application and
handling.
The advice aimed to deliver both water quality improvements and important cost
savings to farmers at a time of rising input costs.
The establishment of unploughed buffer zones around fields near rivers was also
encouraged as a way of controlling diffuse pollution.
Potential savings from carrying out the advice were estimated a by the project and indicated a
benefit/cost ratio of about 3:1. Potentially, savings of £100m could be made if the project was
rolled out across the south east region. Project estimates showed that if the savings advised
in the land holdings of the hotel and education sectors alone were applied to the whole South
East Region, the amount of water saved would be approximately equal to 20% of the annual
flow of the River Darent at Hawley.
2.9 Other research
While we have not been able to directly compare specific land management measures costs
with water treatment costs, evidence indicates that these measures have economic benefits.
2.9.1 Peatlands
Upland peatlands are the primary source for most (70%) of the UK’s drinking water. Healthy
peatlands provide high quality water that can be treated at low cost to drinking water
standards (IUCN, 2011). Drainage of peat from upland catchments damages the land, and
affects the quality of water (Holden et al. 2006).
Damaged peatlands ‘produce higher concentrations of organic ‘brown water’ carbon, which
has to be removed at high cost’ (IUCN, 2011:6). The IUCN calculated that restoring peatlands
has considerably lower costs to society than the price of allowing them to remain
Page | 11
damaged. Cost-effectiveness is due to the subsequent reduction in carbon emissions,
improving water quality (while reducing the costs for drinking water treatment) and conserving
biodiversity. This cost-effectiveness is increased by early intervention, which involves lower
restoration costs (IUCN, 2011:6).
2.9.2 Wetlands
Wetlands offer a number of benefits including areas for recreational activities such as hiking,
fishing, bird watching, photography and hunting. More than 82 million Americans took part in
these activities in 2001, spending more than $108 billion on these pursuits. (Source: USFWS,
Ducks Unlimited).
A wetland’s natural filtration process can remove excess nutrients before water leaves a
wetland, making it healthier for drinking, swimming and supporting plant and animal life. For
example, the Congaree Bottomland Hardwood Swamp in South Carolina removes a quantity
of pollutants from the watershed equivalent to that which would be removed by a $5 million
treatment plant (EPA, 2006). According to one assessment of natural ecosystems, the
monetary value of wetlands worldwide was estimated to be $14.9 trillion (Costanza et al.,
1997).

3.0 CONCLUSION
Water companies are not able to share data needed to assess the comparative costs of
drinking water treatment with and without sustainable land management measures, as this
information could potentially give competitors an advantage. We conclude that the
commercially sensitive nature of water treatment costs means it is not currently possible to
make direct comparisons of the costs and benefits to water treatments using sustainable land
management measures. We also conclude that:
Despite this, the available evidence suggests that these measures are valuable to
water companies and to improving water quality more generally because of the range
of economic, social, environmental benefits produced
Restoring peatlands is known to improve water quality and reduce water treatment
costs; early intervention to restore damaged peatlands further increases cost-
effectiveness.
Investing in sustainable land management measures leads to wider benefits, both
tangible (e.g. carbon sink through afforestation) and non-tangible (e.g. the provision of
desirable habitats and recreational places).
The early stage of many of the projects reviewed means that measuring the
comparative costs of drinking water treatment with and without sustainable land
management measures is still in development.
Based on these conclusions, we recommend that:
1. A mechanism is needed to allow water companies’ data on water treatment to be used to
assess the cost-effectiveness of their investments in sustainable land management measures.
We understand that transparency of data does not fit with commercially sensitive information.
We suggest that:
o Water companies should report information to the Water Industry Commission for
Scotland so that this information can be used to evaluate current sustainable land
management initiatives and help provide evidence to shape future water management
policy.
2. A method of data collection is needed to ensure future comprehensive cost-benefit analysis
of sustainable land management measures. We suggest that:
o Baseline assessments of environmental status, including water quality and biodiversity,
are made before measures are implemented
o A monitoring strategy is implemented to compare water quality and wider
environmental factors including biodiversity, at appropriate stages of implementation
o Cost benefit analysis should include the tangible and intangible costs and benefits to
water consumers and to society more generally.
