All across rural Hampshire, there are properties that are disconnected from the main sewer system. Instead, these properties use private ‘off-mains’ alternatives: cesspits, septic tanks, and sewage treatments plants. When working well, these systems aren’t a cause for concern. But when something goes wrong, both people and wildlife can be put at risk.
While things like tree roots and ground movement are hard to predict, the most common problems stem from systems being improperly sized, sited, or maintained. These issues can lead to sewage pollution that damages property and dramatically impacts biodiversity. Luckily, this expensive and messy situation can be avoided with a little know-how.
Join Ali Morse, Water Policy Manager for The Wildlife Trusts, as she delves into the murky world of these off-mains sewage systems. Hear about the potential environmental impacts that they can cause, and learn tips on how to manage your system to avoid harm.
