Wastewater treatment plants
Biological treatment plants and wastewater treatment plants for homes, BIO platforms and separators for various scales, from single-family homes and hotels to municipal and industrial installations. Systems are sized according to population equivalent (PE) or flow rate.
For private properties see wastewater treatment plants for homes, BIO-6 series or completed projects with installations across Bulgaria.
| Series | PE | Volume / 24h | For whom |
|---|---|---|---|
| BIO-6 | 6 PE | 0.9 m³/24h | single-family houses and villas |
| BIO 6 – 25 | 6–25 PE | 1–4 m³/24h | small residential and hotel sites |
| SEPTIC TANK 1500 L | 4 PE | 1500 l | single-family houses and villas |
| SEPTIC TANK 2500 L | 8 PE | 2500 l | single-family and two-family houses |
| BIO 30 – 200 | 30–200 PE | 5–30 m³/24h | holiday complexes |
| BIO 250 – 2000 | 250–2000 PE | 38–300 m³/24h | settlement industrial site |
| Water tanks | 2-300 PE | 2–300 m³ | drinking water rainwater domestic wastewater |
Wastewater treatment plants, tanks and separators
Choose capacity by population equivalent (PE) or flow rate and wastewater type, from wastewater treatment plants for homes to solutions for 2000+ PE. ERMAX BG engineers will guide you to the optimal BIO platform, separator or combination of equipment for your site, with clear parameters for installation and maintenance.

Wastewater treatment plants for homes
For single-family houses and villas, the typical home wastewater treatment plant is a compact BIO platform with a capacity of 2 to 6 PE. The choice depends on the number of occupants, the sanitary fixtures and how the property is used (all year round or seasonally).
BIO-6: wastewater treatment plant for homes is the most commonly used model for private properties. For larger houses and small hotels, see the BIO 6–25 series in the catalogue below.
Prices of wastewater treatment plants for homes
The final price includes sizing, delivery, installation and commissioning, with no universal online price in the catalogue. After a brief technical assessment we prepare an individual quote; enquire via contacts or booking an appointment.
Frequently asked questions
- How much do home wastewater treatment plants cost?
- Prices depend on capacity (PE), soil type, installation depth and logistics. ERMAX BG prepares a custom quote after a technical assessment, no fixed online catalogue prices.
- Which domestic treatment plant suits a single-family house?
- A typical house uses a compact BIO platform, e.g. BIO-6 (6 PE). Sizing depends on occupants, sanitary fixtures and local wastewater requirements.
- Drinking-water or wastewater treatment plant?
- ERMAX BG biological plants treat wastewater (sewage), not drinking water. They treat sanitary effluent before discharge; drinking water needs different systems.
- Where can I see references and completed projects?
- See Completed projects and References for real installations and partners, evidence instead of anonymous online reviews.
- What is a wastewater treatment plant?
- Wastewater treatment plants biologically treat domestic and industrial sewage. BIO series cover single-family homes through 2000+ PE.
