Plan to change the sludge handling process

Since the sludge handling process used by AS Tallinna Vesi is technically not compliant with all of the newly introduced requirements set forth in the regulation no. 24 issued by the Minister of Environment and consequently, AS Tallinna Vesi has ceased making soil for greening out of sludge and distributing it to customers since the beginning of 2018. Therefore, the water company is currently looking for new opportunities to treat and recycle sludge. The company intends to choose the drying technology and develop the treatment process so that sludge can be recycled or burnt. Until the implementation of the new treatment process, sludge will only be distributed to waste handlers holding a waste permit.

In the near future, the company will launch procurements to find a waste handling company, which can take wastewater sludge from AS Tallinna Vesi. Tenders will also be carried out for the design and construction of the relevant upgrade to the sludge treatment process. The cost of waste treatment by the waste handling company and the cost of modifying the treatment process of the company will be known after the procurement.
