Hydroelectric power stations

The preparation and implementation of hydroelectric power projects has its permanent place amongst services provided by AQUATIS a.s..

Hydroelectric power plants (HE) play a significant role in generating electricity around the world and in the Czech Republic and rank amongst renewable energies with a long service life. They are used in areas with sufficient hydropower potential, i.e. areas with available and adequate flow-rates and gradients. Their concept is highly variable according to local conditions and operational requirements and covers a whole range from large  essential sources of electricity to local small distributed sources.

The hydroelectric power stations are divided according to the design gradient into low pressure (up to 20 m), medium pressure (up to 100 m) and high pressure stations .

According to the method of operation they are divided into constant load, peak load and pumped storage hydro electric power stations.

According to the layout, they are divided into weir, derivation and dam power plants .

WASTEWATER TREATMENT PLANTS

Wastewater treatment plants, including facilities fitted with drained wastewater treatment equipment are of permanent interest within the AQUATIS a.s. operations.

We design wastewater treatment plants of various sizes:
from urban wastewater treatment plants (large cities with a capacity of hundreds of thousands of population  equivalent), 
through medium-sized WWTPs (cities with a capacity of tens of thousands of population equivalent), up to small wastewater treatment plants for smaller units (thousands of population equivalent).
we design new WWTPs as well as reconstruction and extension of existing WWTPs, when modifications to the WWTP are addressed in a manner which ensures operation of the existing plant

We provide:
Preparation of design documentation - from sewer survey to sewer data collection incl. all engineering surveys necessary for the WWTP design....

Flood protection

The objective of flood protection structures (PPO) and measures limiting the adverse impact floods is to reduce the risk of casualties and damage to property and the environment due to flood events. These measures and structures form  an important part of services provided by AQUATIS a.s.

Following extreme floods that affected the Czech Republic in the past, the perception of the urgency of preparing preventive flood protection measures has changed. Likewise, the approach regarding the design of flood protection measures and structures has been reviewed. This is based on determining the flood protection concept. Flood protection studies provide is a comprehensive evaluation of the current situation in the area of interest, specify weak points and define flood protection objectives including proposed steps of solution and specific measures....

Modification and revitalization of watercourses

The aim of revitalization projects is to return the existing channelized waterway to a state close to nature. In cities, but also in rural areas, the waterways were often straightened in the past, land was reclaimed and drained and riverbeds were stabilized using, for example, paving stones into concrete. In recent decades, this trend has been abandoned mainly because it turns out that these measures accelerated flood events and contributed to the drying out of the landscape.
Agricultural land was often protected by dykes at the expense of cities and these dykes were hit all the harder by floods. 

The revitalization measures return the much-needed water bodies to nature, be it wetlands, lakes, reservoirs or water course or river meanders. All these measures serve to retain water in the landscape and to return animal and plant species back to nature.

Waterways and navigation

As part of this field of operations AQUATIS a.s. develops various stages of documentation ranging from studies to as-built design documentation concerning navigation channels and canalized parts of waterways, including navigation facilities.

These manly cover lock chambers, ship hoists, lock anchorage, quay walls, docks, ports for cargo vessels and recreational vessels.

The work also includes designing of service centres supplying the vessels with fuel and drinking water and ensuring waste collection. The delivery also includes technological parts of the facilities and mechanical and electrical components. The facilities are designed with the least possible disturbance of the natural environment.

Project realization
Rubber dams

Rubber dams are a modern type of movable and fully automatic weir control system. Due to their relatively low prices and simple operation, they offer an ideal solution for small hydroelectric power plants and for other facilities requiring  impoundment and its control. AQUATIS a.s. has designed rubber dams for over 50 years. Besides developing design documentation, we also deliver turnkey projects. Our employees provide related engineering services consisting of supervision during assembly, commissioning and warranty services. AQUATIS a.s. in cooperation with the manufacturer of rubber-textile material used for rubber dams, Rubena s.r.o., has implemented more than 230 rubber dam projects. In addition to about 110 rubber dams installed in the Czech Republic, Slovakia and Poland, AQUATIS a.s., in cooperation with the Austrian company Hydro-Construct GesmbH Steyr....
