This paper describes a sustainable and integrated approach used to manage issues relating to flood
risk, poor local water infrastructure, water resources and poor surface and groundwater quality during
the reclamation and redevelopment of an approximately 0.9km2 former colliery site in Nottinghamshire, UK.
These issues were sustainably overcome by using; rainwater harvesting, an onsite wastewater
treatment plant and rehabilitating a water supply borehole to avoid the use of limited local water
infrastructure. The deculverting and restoration of a formerly culverted watercourse and provision of a
spillway to mitigate rebounding groundwater levels in a former quarry to manage flood risk and
improve low flow conditions in the watercourse. Bio-remediation of contaminated soils and insitu
groundwater remediation to improve aquifer quality and SuDs techniques such as; attenuation ponds,
swales, filter drains and permeable paving to attenuate storm water, improve surface water quality
and reduce surface water discharges to the receiving watercourse.
KEY WORDS: Water management, flooding, river restoration, spillway, sustainable urban drainage, remediation, onsite wastewater treatment, water supply borehole.
