Exeter and East Devon Water Cycle Study
Table 9.1 – Proposed Water Cycle Sustainability Objectives
Objectives Key Indicators
Water resource and water supply
Objective: To ensure that water consumption and supply is as efficient as possible.
• Reduce the consumption of water, both domestic and industrial (i.e. introduction of water metres, tariffs
and other demand management measures).
• Make best use of past investments and assets including existing buildings and infrastructure.
• Promote sustainable water use based on long-term protection of available water sources.
• Contribute to mitigating the effects of drought.
• Increase public awareness
Water quality and environment
Objective: To reduce pollution and maintain a high quality of water environment.
• Ensure the progressive reduction of pollution of groundwater and prevent further pollution.
• Achieve good ecological and chemical status in all inland and coastal waters by 2015.
• Conserve and enhance SPAs, NNRs and SSSIs.
• Ensure that coastal floodplain habitats are not prevented from naturally responding from sea level rise.
• Employ green infrastructure principles (e.g. rain water harvesting, green roofs, attenuation ponds.)
Wastewater drainage and treatment
Objective: Effective management of waste water: reduce the amount of waste water produced, better use of waste water.
• Minimise waste water by better demand management and separation of storm water from foul sewers.
• Make best use of past investments and assets including spare capacity in existing infrastructure.
• Encourage recycling of waste water and reduction in energy use by residences and businesses.
• Promote low carbon wastewater infrastructure solutions (e.g. gravity drainage rather than pumped).
• Develop new markets for waste water.
Flood risk and surface water management
Objective: To ensure that there in no increase in flood risk.
• Guide development away from areas liable to flooding by the use of a sequential test approach to land
use planning.
• Further reduce existing flood risk.
• Employ sustainable flood risk solutions.
• Contribute to mitigating the effects of floods – promote flood resilience.
• Increase public awareness
