Untreated sewage poses serious health and pollution risks. Andel’s PRO 6 and PRO 12 STP range use a reliable three-chamber process to clean domestic wastewater before it reaches watercourses or drainage fields, keeping your site compliant and environmentally responsible.
Septic tanks no longer meet discharge standards. STPs offer full compliance, treat wastewater efficiently, and need less frequent emptying, with long-term reliability.
While the PRO 6 and PRO 12 models are designed for up to 6 and 12 people respectively, they can be installed in multiples with connected pipework to increase capacity.
This modular approach offers scalable wastewater treatment for larger sites without the need for oversized single units.
Andel’s tanks are constructed from robust, lightweight HDPE, providing long service life, easy installation and greater resistance to leakage compared with traditional GRP tanks.

Each system incorporates integrated odour control and lockable, airtight access covers to prevent unpleasant smells on site.
Yes. The lightweight design means installation can often be completed without heavy lifting equipment, making them ideal for restricted or sensitive sites.
Routine emptying of settled sludge and standard servicing in line with Environment Agency guidelines keep the system performing efficiently.
Absolutely. While the PRO 6 and PRO 12 models are designed for up to 6 and 12 people respectively, they can be installed in multiples with connected pipework to increase capacity for schools, hotels, business parks and other commercial applications.

All systems come with a 10-year tank warranty, reflecting Andel’s confidence in their quality and long-term performance.
