For a business, the sewerage system is not just a ātechnical detailā ā it affects day-to-day work, hygiene, customer experience and costs. That’s why a sewerage solution for a business should be chosen with the load, reliability and easy maintenance in mind. This is especially relevant for cafĆ©s, production plants, warehouses, offices, car services and sites in places without a central sewer connection.
How do a business’s needs differ from a private house?
In private houses the load is usually similar every day, but in businesses it can vary a lot. One day there are many visitors, the next few. On some sites the main load is only during working hours, while on others the volume of wastewater rises sharply in certain seasons. So the capacity should be chosen not āby eyeā, but based on a realistic usage scenario.
How to choose the capacity and type of system?
To find the most suitable solution, first answer a few questions:
- how many people are on site on a normal day and at peak times
- whether there is a flow of customers and peak hours
- which processes produce wastewater (only domestic, or also from production)
- whether fats, oils or other specific contaminants go into the sewer
For example, catering businesses often need additional solutions that help control the amount of fat entering the system, so that treatment works more reliably.
Discharge and maintenance matter as much as the plant
A common mistake is to focus only on the plant model and not plan the discharge. The treated-water discharge solution may be infiltration, discharge to a ditch or a solution with a pumping station. The choice depends on the soil, terrain and distances.
Maintenance is also critically important for a business. If the system stops, it can mean downtime or problems serving customers. So it’s best to choose a solution with a predictable maintenance schedule and clear availability of service.
How we installed an AT-12 under a roadway in Suntaži
The site is in an active production area with regular lorry traffic. This meant the new biological treatment plant not only had to provide high-quality wastewater treatment for up to 10 people, but also withstand heavy mechanical loads from traffic.
First we assessed the connection options, the existing sewer, the layout of the building and the traffic flow in the yard. The ideal location for the plant turned out to be right under the roadway, between the building and the yard where vehicles stop every day.
Next came the excavation and building the concrete ring shaft. The AT-12 plant was installed inside a concrete ring shaft, which provides extra mechanical strength and safety when lorries drive over it. We filled the plant with water, connected the inlets and the treated-wastewater outlet, and prepared the air supply and power connection for the AUGUST control unit.
Once all the technical connections were ready, we used machinery to lay heavy concrete cover slabs. This step is essential so that the traffic load is distributed evenly and the treatment plant does not settle or get damaged in the long term.
