At Smart Flow NE, we specialise in advanced wastewater management solutions for residential and commercial clients. Our projects meet the highest environmental compliance and system efficiency standards, from septic tank upgrades to full sewage treatment plant installations.
Following new environmental regulations, a long-term client needed to replace a non-compliant septic tank at their rural property. The system discharged into a nearby watercourse and breached the Environment Agency's General Binding Rules. Smart Flow NE designed, supplied, installed, and commissioned a bespoke sewage treatment plant that met all compliance standards. The system now treats wastewater effectively, prevents pollution, and protects the environment.
This project highlights our end-to-end expertise and commitment to delivering sustainable, regulation-compliant wastewater solutions.
Septic tanks and sewage treatment plants manage wastewater where mains drainage isn't available. Explore our FAQs below for more details.
A septic tank is an underground chamber that collects and partially treats wastewater from properties not connected to mains drainage. It separates solids, allowing the liquid to safely disperse through a soakaway system.
While bacteria break down some waste, sludge builds up over time. If not removed, it can block the system. Regular emptying (desludging) is essential to keep your tank working safely and efficiently.
Most tanks should be emptied every 12 to 36 months, depending on usage. Industry guidance recommends desludging when solids reach around 30–50% of the tank's volume.
Common causes include poor ground conditions, improper soakaway installation, and neglecting desludging. Solids can block the drainage field if not managed, leading to complete system failure.
Avoid flushing bleach, fats, oils, wipes, nappies, sanitary products, paper towels, paints, and chemicals. These harm the bacteria needed for natural waste breakdown and can clog the system.
Strong odours may indicate the bacterial balance has been disrupted, often by chemicals or unsuitable waste. A biological treatment may be required. Contact a specialist to assess and service the tank.
Scum forms from fats, oils, and grease (FOG) that float on top of the tank. This is normal, but if it hardens, oxygen can't circulate, and treatment stops. A thick, dry scum means desludging is needed.
