## Summary

United Utilities Water Limited has completed the procurement process for the "PRO004930-Goods-Contract-MBBR 65 Units (Addendum)" project in the utilities industry, which was carried out through a direct award as per the Procurement Act 2023. The contract involves the acquisition of machinery necessary for sewage treatment, specifically 3 MBBR65 units, 3 D100 DAF Units, 2 Flow Split Chambers, and 1 D/A/S Blower Skid, valued at approximately £1,800,000. The procurement, now in the award stage, was driven by technical reasons to avoid operational disruptions, with the contract period extending from 13th November 2025 to 12th October 2026. The project location is within the United Kingdom, and the recent award notice was published on 13th November 2025.

This procurement presents significant opportunities for businesses in the sewage treatment equipment supply industry, particularly those with expertise in providing advanced machinery compliant with regulatory specifications. The successful supplier, Siltbuster Limited, a small to medium-sized enterprise based in Monmouth, demonstrates that businesses capable of delivering specialised treatment systems, handling direct award processes, and understanding technical requirements can effectively engage in such contracts. Companies aiming to explore growth opportunities in the utilities sector should consider the potential for future direct awards, especially where maintaining existing goods is critical to operations.

## Notice

The procurement is to secure 3 x MBBR65 units, 3 x D100 DAF Units, 2 x Flow Split Chambers and 1 x D/A/S Blower Skid at a value of circa PS1,800,000.

### Procurement Information

Under the Procurement Act 2023, direct award is permissible for technical reasons in situations where a competitive tender would lead to disproportionate technical difficulties when operating or maintaining existing goods. The MBBR systems are now in place and to maintain regulatory compliance they must remain operational. To potentially change the supplier, resulting in the requirement to drain down the live assets and de-install we would be increasing the likelihood of multiple sewage spills affecting the sites compliance and possibility of being classified as a failing works.
