Andy Hornbuckle (AU)

SPEL Stormwater

Stormwater Shepherds is Andy Hornbuckle’s brainchild; he is also the General Manager of SPEL Stormwater – a global manufacturer and importer of various internationally-proven stormwater treatment systems. During his decade tenure at SPEL, he has witnessed the urban catchment pollution entering the storm drains and making its way to the oceans and beaches via creeks and wetlands, lakes and rivers.

Andy has led SPEL Stormwater through a journey of innovation and revitalisation, starting from the Stormceptor and Puraceptor systems to capture and remove hydrocarbons through to ecological systems including Modular Bioretention and Floating Wetland systems. He has also initiated a series of field research and evaluation projects on SPEL Stormwater products to benefit the industry and environment with scientific data that is rigorous, transparent and independent.

Andy has a passion for Stormwater and Water Sensitive Urban Design. From his inspiration and passion, he founded Stormwater Shepherds to educate the public and raise awareness in the catchments at the pollution source.

Jo Bradley (UK)

Stormwater Shepherds

Jo Bradley has worked on many aspects of water management during her 30-year career in the UK. She has worked in a clean-water laboratory, been a Trade Effluent Officer, overseen Drought Plan development and taken endless sewage samples. But her passion lies in pollution prevention & control and she was lead author on some of the Environment Agency’s Pollution Prevention Guidance notes, which were widely respected and applied. She focussed on topics including oil/water separator design & application, private sewage treatment systems and retail petrol filling stations.

But in the last decade, Jo’s attention has been on pollution from urban surfaces and roads. She managed a joint Environment Agency/Highways Agency project to prioritise the highway outfalls on the Strategic Road Network in terms of their pollution risk, and she has worked with design engineers to create effective treatment schemes for some of those priority outfalls. Jo is also determined to see good SuDS used extensively across England, with similar success to that in Scotland and Wales and she firmly believes that if they are designed properly, SuDS can be applied on every development.

Jo was delighted to join Stormwater Shepherds in September 2020 and she is intent on driving pollution control forward in the UK, faster than it has gone before, so that we can achieve zero-pollution in her lifetime and protect rivers & oceans and all the creatures that live within them.
