Navigating Bespoke Environmental Permits for Campsites on Sensitive Aquifers<\/h1>\n<\/header>\n
\n

Operating a thriving campsite or holiday park comes with significant environmental responsibilities, especially when your site sits above a sensitive groundwater zone. We recently consulted on a case for a high-capacity campsite operating over a Secondary A aquifer<\/strong> with an archaic septic tank and soakaway system. Because the site generates well over the 2,000-litre daily threshold, it falls entirely outside the General Binding Rules, requiring a complex bespoke environmental permit.<\/p>\n

If you are managing a large off-grid site, here is what you need to know about upgrading your systems, applying Best Available Techniques (BAT), and navigating the complexities of Quantitative Groundwater Risk Assessments.<\/p>\n

\"\"<\/p>\n

Why an Old Septic Tank Won’t Cut It<\/h2>\n

A septic tank only provides primary treatment, essentially settling out solids before discharging wastewater. When discharging large volumes of effluent into a highly permeable Secondary A aquifer\u2014which often supports local water supplies and river base flows\u2014primary treatment poses an unacceptable risk of contamination.<\/p>\n

To meet the Environment Agency’s (EA) requirement for Best Available Techniques (BAT), sites of this scale are generally forced to upgrade to a modern Package Sewage Treatment Plant (STP). These systems provide active biological, secondary treatment, drastically reducing the pollutant load before it reaches the ground.<\/p>\n

The Role of a Groundwater Risk Assessment (GWRA)<\/h2>\n

Upgrading the hardware is only half the battle. To secure a bespoke permit, you must prove to the EA that your local ground conditions can safely dilute and attenuate the remaining treated effluent. This requires a tiered Groundwater Risk Assessment (GWRA)<\/a>.<\/p>\n

Initial assessments often rely on conservative desk studies and shallow trial pit percolation testing. We highly recommend utilizing open-source data early in your planning to understand your site’s baseline sensitivities:<\/p>\n
