Easily adaptable to suit any environment and application and available in a wide range of capacities, our septic solutions are the ideal solution for your effluent waste management projects.

Pump Pits: COERCO’s pump pits feature high-quality, one-piece construction that’s supremely durable, reliable and cost-effective. They are suitable for a wide range of pumps and come with a design that facilitates fast, easy and secure access to pumps anywhere, everywhere.

Grease Traps: Our grease traps are an effective and hygienic way to separate fat and grease from wastewater flow, thus protecting mains drainage systems from grease blockages and facilitating the optimal performance of sewage treatment plants.
