How has Edinburgh’s waste been treated in the past? How is it treated today? From sewage being tossed onto the streets, to the Gardyloo ship, to today’s modern treatment methods including how green energy is generated in the process, this is a tour like no other.
Seafield is Scotland’s largest wastewater treatment works, treating the wastewater from the population equivalent of 850,000 people and is open for organised tours on Doors Open Day. Seafield utilises biogas captured during the treatment process, generates green energy from this and at times can be completely self sufficient and even export electricity to the national grid.
