20 - 50 Person Sewage Treatment Plants
At Tanks Direct, we offer a comprehensive range of high-capacity sewage treatment plants specifically designed for properties with 20 to 50 occupants. These advanced systems treat wastewater to a very high standard, making them perfect for locations that are not connected to mains drainage. They're ideal for hotels, resorts, office buildings, and even large residential developments. Compared to traditional septic tanks, sewage treatment plants offer a more sustainable solution with a smaller footprint and significantly lower maintenance requirements.
You'll find a wide choice of top-tier sewage treatment plants from leading brands like Klargester, Clearwater, Harlequin, and Premier Tech. We offer both gravity-fed and pumped options, so you can choose the system that best suits your site conditions. Keep an eye out for features like energy efficiency, built-in alarms for potential issues, and easy access for maintenance.
We're committed to providing the most competitive prices on the market, and we even offer a price match guarantee to ensure you get the best value. We offer a variety of payment options, including Mondu’s B2B convenient pay later and instalment plans. Our dedicated team of experts is also here to answer any questions you may have and help you choose the right high-capacity sewage treatment plant for your property.
