01What is being requested

This project concerns the replacement of the grit removal installations at RWZI Scheemda by Waterschap Hunze en Aa's, carried out via a negotiated procedure without publication. The procurement was closed due to a calamity that led to inefficient contamination and increased maintenance costs. A construction team agreement with the chosen market party (contractor) is the contract form.

The board of Waterschap Hunze en Aa's has released execution credit to replace the grit removal installations of RWZI Scheemda. Due to a calamity (both existing screens have failed), the intended project-based approach has been accelerated. The defect of the existing screens means that the sewage entering the RWZI is not cleared of coarse debris. This debris enters the subsequent installation components. It is possible that the debris is partially discharged into surface water with the effluent water. The debris causes a less efficient purification process, leads to accumulations in the purif

06Frequently asked questions

What is the reason for the accelerated approach to the replacement of the grit removal installations?

Due to a calamity in which both existing screens became defective, the approach has been accelerated. The defect ensures that sewage is not cleared of coarse debris, which leads to inefficient purification, blockages, wear to machinery, and the risk that discharge standards for nitrogen, phosphate, and coarse particles are not met.

Which contract form is used for the realization of the drum screens?

A construction team agreement is being used. During the construction team phase, the execution plan is elaborated in detail with a cost specification. The contractor then has the right to be the first to submit a tender for the realization phase, which is agreed upon based on a cost specification approved by the contracting authority and in accordance with market conditions.

What is the intended operational date of the new installation?

It is expected that the new installation will be operational before 1 February 2025.

What risks are associated with the use of the current temporary installation?

The temporary installation has a lower capacity, no reserve setting, and a larger screen size than desired. Additionally, there are possible negative Arbo-technical consequences, such as exposure to biological agents and a non-ideal workplace at height.
