Wastewater management

Wasterwater Management

Sewage management, safe treatment and treated effluent disposal are essential features for a community to safely grow and promote citizen’s interests. Sewer network is the key element necessary to be safely deployed so as to:

  • facilitate the WWTP’s or disposal location capacity;
  • minimize the production of odors from the collection point to the discharge location;
  • minimize the accumulation of solids and gases in the mains;
  • achieve maximum sewerage network reliability and availability with minimum maintenance;
  • minimize the number of pumping stations and the cost of energy required to transport and treat sewage;
  • minimize design weak points that might lead to a poor construction (such as theoretical miniscule longitudinal slopes that look great on the computer screen but terrible on site!).

Modern drafting and modeling software are used for the design of new and the verification, expansion or modification of existing sewer systems.

We run network simulations for an extended period, commonly for 24hrs of both the estimated peak day of the design period of the system and of the minimum expected flow. The peak scenario is used for the sizing of the network and the minimum to assess sediments and Sulphur dioxide accumulation and propose measures for the optimum operation of the system (e.g. clean out manholes).

Drafting software ensures the clash analysis between all the underground utilities during the design process. Final deliverables are BIM ready and can be exported to the required system.

Interoperability of the used I.T. systems ensures the highest quality of the final submission within time and budget.

When dealing with existing, old sewer networks that either need extension (to serve new areas) or rehabilitation (leakage, repeated blockages etc.), we have access to cutting edge inspection and decision making tools that help design and propose the optimum solution.

Sewer networks are commonly regarded as expensive and capital intensive infrastructure investment. On the other, the cost of inadequate investment in modern, well designed communal sanitary solutions is far more expensive in terms of direct and indirect damages and socioeconomic implications. Sewer projects are vital for the hygiene, well-being and the evolvement of the local community.

In case of privately funded projects it is best to asses potential exploitation of byproducts in Waste Water Treatment Plant, such as anaerobic digestion of the produced sludge for the production of energy. We have experience on project funding from EBRD, World Bank, EIB and other sources. Our experienced team can prepare the proposal dossier and follow the project until it is completed and fully paid.
