EXPLANATION
|
|
Asset (above ground)
|
Network elements and property situated above ground which is owned by
Scottish Water (e.g. treatment works)
|
|
Asset (below ground)
|
Network elements and property situated below ground which is owned by
Scottish Water ( e.g. underground pipes)
|
|
Capital Maintenance
|
"Capital maintenance" describes the ongoing investment required
in Scottish Water assets such as underground pipes and over ground treatment
works to maintain the existing levels of service in terms of water quality,
environmental performance and customer service
|
|
Capital maintenance spend
|
Amount spent on capital maintenance
|
|
CFA
|
Common Framework Approach - The Q&S III Project used a number of
approaches to determine the required level of capital maintenance spend
. These include the Common Framework Approach developed by UK Water Industry
Research Ltd which seeks to establish the relationship between capital
maintenance spend and customer service standards.
|
|
Coliforms
|
Coliforms (i.e Faecal Coliforms) are present in the gut of all warm blooded
animals. Their presence in water supplies indicates a breach of the integrity
of the water supply system and that faecal pollution may have occurred.
|
|
Core services
|
Scottish Water functions under or by virtue
of the Sewerage (Scotland) Act 1968, The Water Industry (Scotland) Act 2002
(excluding its functions under subsection (1) of section 25 and sub section
(2) of that section so far as relating to subsection (1) ), and any other
enactment (source - section 70 (2) of the Water Industry (Scotland) Act
2002 |

|
Cryptosporidium
|
Cryptosporidium is a protozoan parasite
found in man, many other mammals and also in birds, fish and reptiles. This
microscopic pathogen can cause a disease called cryptosporidiosis which
is usually characterised by an acute self-limiting diarrhoeal illness. |
|
CSO
|
Combined sewer overflows are flood relief structures that discharge storm
water to watercourses during heavy rainfall.
|
|
Deeper elements of connection
|
Deeper elements of connection or "deep" reinforcement relate
to the elements of the network which are remote from the connection point
but may still require uprated e.g. developing water resources (including
bulk mains and treatment plants), or increasing the capacity of sewage
treatment works
|
|
Deliverable
|
By deliverable, we mean an investment programme which recognises
that there are constraints on the level of investment activity it is possible
to deliver. These include the level of civil engineering capacity available
in Scotland, the ability of Scottish Water to deliver these works, and
the level of disruption that communities can tolerate e.g. in terms of
road works.
|
|
Development Constraints
|
When local development is constrained by the fact that the existing water
and sewerage services are inadequate to service a new development.
|
|
Development constraints - release of
|
When the water and sewerage capacity is extended to accommodate new developments
|
|
Driver
|
Something that "drives" us to invest in water services - e.g.
legislative standards and customer priorities

|
Laterals
|
Uniquely within the UK, Scottish Water has responsibility
for a significant number of sewers laid in customers’ properties, gardens
etc. These sewers are known as laterals. |
|
Modelling work
|
Work done to establish which model (or approach) may be suitable for
identifying investment needs and costing those needs. Also, the work done
in applying the chosen model.

|
|
Serviceability Indicator
|
Measures that inform judgements about the fitness for purpose of the
water and sewerage asset systems to maintain service to customers and
to the environment. These measures are used to understand service to customers
and to the environment and also the performance of the assets
|
|
Sewer collapse
|
Structural collapse of a sewer that prevents the sewer from serving the
purpose of carrying sewage. Partial collapses also occur which do not
completely prevent the sewer from carrying sewage but may cause an increase
in blocking and decrease performance.

|
Sludge
|
Residual sludge from sewage plants treating domestic or urban waste waters
and from other sewage plants treating waste waters of a composition similar
to domestic and urban waste waters

|
Surface water outfall
|
Outfall from waste water treatment works into surface waters
|
|
Sustainable
|
by sustainable we mean a programme which delivers environmental
improvements but at a cost and pace that is fair and equitable for current
and future generations.
|
|
Telemetry
|
Monitoring equipment installed at water treatment works and in the distribution
system, which sends signals/alarms to a central control room that is remote
from the works.
|
|
Trihalomethanes
|
Trihalomethanes occur in drinking water principally
as products of the reaction of chlorine with naturally occurring organic
materials and with bromide, which may also be present in the water. In controlling
trihalomethanes, a multi-step treatment system should be used to reduce
organic trihalomethanes precursors. Primary consideration should be given
to ensuring that disinfection is never compromised. |

Water abstractions
|
The term water abstraction is currently under
review - for further details please refer to the Scottish Executive Consultation
"Controlled Activities Regulations" April 2004 (Paper 2004/8).
The definition proposed in that consultation is - "abstraction"
means in relation to the water environment, the doing of anything whereby
any water is removed or diverted by mechanical means, pipe or any engineering
structure or works from that water, whether temporarily or permanently,
including anything whereby the water is so removed or diverted for the purpose
of being transferred to another area of the water environment, and includes:
(a) the construction of any well, borehole, or other work by which water
may be abstracted; (b) the extension of any well, borehole, surface water
or other work; or (c) the installation or modification of any machinery
or apparatus by which additional quantities of water may be abstracted by
means of a well, borehole, or other work. |
