Wastewater Treatment Projects
As a professional in the field of wastewater management, I have been instrumental in the efficient and environmentally friendly treatment and processing of municipal and industrial wastewaters. It is due to the application of advanced biological, chemical, and physical processes that I can minimize the adverse consequences of wastewater effluent. Furthermore, this has made it possible to reclaim and utilize water, nutrients, and energy among other beneficial resources.
This has been an area of work driven by passion for sustainability and stewardship of the environment. I have always been in search of the ways that will optimize wastewater treatment systems depending on the smallest time with the highest efficiency of the system’s work without damaging the environment. Therefore, it has required looking for and using a number of advanced technologies, from more complex biological treatment systems to new methods of resource recovery systems.

Contract for Design, Supply, and Installation of Civil, Mechanical, and Electrical Works for the Sewage Treatment Plant Construction in Zugdidi, Georgia.
Contract No. UWSCG-USIIP-ICB-REG-03a
Contract Value: 12.679.471,29 EUR
My Roles:
from August 2020 until August 2021: The Contractor's Executive Director
from February 2018 until August 2020: The Contractor’s Representative Project Manager
The Contractor: Joint Venture of Ludwig Pfeiffer Hoch - und Tiefbau GmbH & Co.KG and EMIT Group - Ercole Marelli Impianti Tecnologici S.r.l.
The Employer: United Water Supply Company of Georgia LLC
The Project Manager: Joint Venture of Posch & Partners Consulting Engineers, Hydro Ingenieure Umwelttnik GmbH, and Wardrop & Alexander as a sub-consultant
The Project was financed by the Asian Development Bank (ADB).
The Project has been executed following the Harmonized FIDIC Yellow Book Contract.
The Sewage Treatment Plant (STP) in Zugdidi, Georgia has been designed to have a capacity of 83,298 people equivalents (PE) for the Design Horizon 2040. This means the plant has been constructed to accommodate the projected wastewater treatment needs of the Zugdidi municipality up to the year 2040. The selected treatment technology is the Activated Sludge Process with separate Anaerobic Sludge Digestion. The treatment process comprises the following steps: Coarse and Fine Screens, Aerated Grit Chamber, Primary Sedimentation Tanks, Aeration Tanks, Sedimentation Tanks, Sludge Thickener, Digestion and Gas Utilisation Plant (CHP - Combined Heat and Power Plant), Sludge Dewatering, Gas Storage, and Gas Torch.
The STP is designed for the PE 83.000 to treat an average daily dry weather flow of 11,122 cubic meters per day (m³/d) of municipal wastewater.
Design, Supply and Installation of the Wastewater Treatment Plant in Ureki, Georgia
Design, Supply, Installation Contract for Ureki Wastewater Treatment Plant, Georgia.
Contract No. P43405-ICB-URE-02
Contract Value: 7.459.808,23 USD
My Role: from January 2017 until February 2018: The Contractor's EIA Project Manager
The Contractor: Joint Venture of Ludwig Pfeiffer Hoch - und Tiefbau GmbH & Co.KG and ARITIM MÜHENDİSLİK İNŞ. SAN. ve TİC. LTD ŞTİ.
The Employer: United Water Supply Company of Georgia LLC
The Project Manager: EPTISA
The Project was financed by the Asian Development Bank (ADB), ADB Loan No: 3078-GEO.
The Project has been executed following the Harmonized FIDIC Yellow Book Contract.
The works comprise the design, construction and commissioning of a new wastewater treatment plant, as well as operating and maintaining the plant for one year during which period there will also be training of the operator’s staff. To meet the effluent standard a reduction of nutrients, such as carbon, nitrogen and phosphorus, has to be implemented. Carbon removal will be realized by using the activated sludge process, whereas the removal of nitrogen will be achieved by providing anoxic areas in the activated sludge process tank. Phosphorus will be removed by precipitation. Surplus biomass (excess sludge) shall be stabilized by simultaneous, aerobic stabilization within the activated sludge process tank.
The WWTP is designed for the PE 40.000 to treat an average daily dry weather flow of 8,212 cubic meters per day (m³/d) of municipal wastewater.

Design, Supply and Installation of the Wastewater Treatment Plant in Anaklia, Georgia
Design, Supply, Installation Contract for Anaklia Wastewater Treatment Plant, Georgia.
Contract No. UWSCG/USIIP/ICB/CW/REG-02
Contract Value: 9.272.589,86 USD USD
My Role: from January 2017 until February 2018: The Contractor's EIA Project Manager
The Contractor: Joint Venture of Ludwig Pfeiffer Hoch - und Tiefbau GmbH & Co.KG and ProtecnoSrl
The Employer: United Water Supply Company of Georgia LLC
The Project Manager: EPTISA
The Project was financed by the Asian Development Bank (ADB), ADB Loan No: 3078-GEO.
The Project has been executed following the Harmonized ENAA Contract.
The project target is the design and construction of a new wastewater treatment plant for the city Anaklia. The treatment process for WWTP Anaklia will be designed as simultaneous activated sludge stabilization (extended aeration activated sludge process) with Carbon and Nitrogen removal, Chemical Phosphorus removal and simultaneous stabilization of surplus biomass. Generated surplus (excess) sludge will be collected, extracted from the Water Line, and further treated on Sludge Line by thickening in Gravity Thickener and finally dewatering on the centrifuge decanters, before its final disposal outside the Plant. After stabilization, thickening and dewatering of surplus biomass it can be safely disposed or used as a fertilizer for agricultural needs. The Treatment process comprises Mechanical treatment of raw wastewater where large particle, coarse materials, sand and grease are removed, Biological treatment where biodegradable organic pollution load is removed together with Nitrogen removal by simultaneous Nitrification/denitrification process in circulating activated sludge Tanks with concurrent surplus sludge stabilization, as well as Sludge treatment.
The WWTP is designed for the PE 25.600 to treat an average daily dry weather flow of 4.253 cubic meters per day (m³/d) of municipal wastewater.
