In terms of rainwater and wastewater, municipal water management systems include sewer and storm‑water structures, wastewater treatment plants and, as the case may be, any parts thereof. Apart from this, there are special sections (for sludge processing) that are shown in the offer separately. The sewer structures are purported to protect the system against grease deposits (grease traps), contamination with oil products (light liquid separators), or for pumping (pumping shafts), flowrate measurements, or acting as a rainwater relief construction in combined sewer systems. Wastewater treatment plants are used primarily for treatment of wastewater produced by the municipality population, and various parts for in‑dividual process tasks ‑ thrash racks for removal of coarse impurities, aeration systems for oxygen inflow and flush‑out flaps for cleaning of retention tanks both in wastewater treatment plants and combined sewer systems.
ASIO offers various standardized wastewater treatment plants, including membrane ones, in addition with non-standard mechanical-biological units, as well as extensive vegetation treatment systems. A part of the offer is also represented by sewer structures or structures protecting sewer systems against discharge of damaging substances.
