Sewage systems

For sewerage systems, SADE undertakes:

• users’ connections to new or in-service networks,
• renovations of connections to in-service sewer networks.

Rehabilitation consists of internally reconditioning a degraded drinking water, sewerage or industrial fluid network, by localised (repair) or continuous treatment (renovation). A network’s rehabilitation contributes to the restoration of its optimum operational conditions. 

Rehabilitation techniques bring : 

• shorter completion deadlines,
• a minimal worksite footprint,
• reduced disturbances to residents,
• operations on sites that are inaccessible by conventional digging.

SADE Serbia implements different rehabilitation processes as slip lining to repair most of the damage suffered by networks, at a cost generally lower than that of trench-type working.

The depollution unit is an essential link in the wastewater collection chain: treating and guaranteeing the discharge of purified water into the natural environment and thus avoiding its pollution. Whether with activated sludge, on reed-bed filters (wet lands) or mixed, the depollution units proposed and constructed by SADE Serbia are a tailor-made response adapted to the type of effluent and other requirements, to the proper geographical context and to the constraints of each municipal or private client. 

SADE Serbia is a complete service provider: study and consultancy, detailed design and construction, operator training and plant maintenance, if required.

SADE Serbia offers  a range of effluent containment solutions.

For the management of pollution hazards, SADE Serbia’s service provision includes:

• risk analysis (network diagnosis, risk identification and evaluation, etc),
• securing of unloading areas,
• blocking-off networks,
• storage or containment tanks
• warning stations
• general pollution detection
• upgrading fire-fighting systems

Underground main sewers serve as ‘buffer’ solutions enabling a sewer network to deal with occasional overloads. In urban areas, underground main sewers linked to sewerage systems can easily handle heavy cloudbursts of rain. 

As well as their design, SADE Serbia is able to undertake all types of underground main sewers with traditional methods of installation (digging and earthworks) or with trenchless techniques (microtunnelling, etc.).
