OSS was engaged to build this laser length measurement panel and control box to the client’s design.
OSS built a CE marked control panel to specific customer requirements, to comply with all legal requirements and to conform to relevant industry standards, including BS EN 61439. In addition, we used our in-house design and manufacture capabilities to deliver a solution that is fit for purpose and is of good quality and value.

The existing chlorination system was replaced with a bulk delivery hypo and batching system.
The flow control through the works was reviewed and improvements identified and implemented.
The addition of a Run to Waste to allow for process stabilisation for overcoming poor quality conditions.
How Did We Stand Out? In a post project review by the Principal Contractor, MMB, it
was communicated back to OSS that we were the only sub-contractor to gain full marks in respect to the assessment of
performance on the scheme.

VIEW PDFOSS worked closely with Black & Veatch, on behalf of DCWW, to deliver a new Rapid Gravity Filtration Plant at Alwen WTW in Deeside, North Wales. The existing SIEMENS APACS Control system with PCS7 OS SCADA was expanded to include a new control system node and SCADA client. The project was delivered within tight timescales and close liaison with the other disciplines on the scheme was essential. More details on the scheme can be found on the following link:
VIEW PDFNew Dissolved Air Floatation and Rapid Gravity Filtration plants were built and constructed at Cwlleyn WTW in the heart of Snowdonia. OSS provided the expertise to develop and commission the APACS/PCS7 OS control system software to meet the DWI date. It was a highly successful project, resulting in an award for OSS from the AMA alliance. Details of the case study can be found within the following Water Projects Online article:
VIEW PDFUnder the Black and Veatch Go to Green programme, the control system at Llyn Conwy WTW was migrated to the new Mitsbushi Servelec solution to align with DCWW's Automation strategy. A technically challenging project, OSS were drafted in to assist with the development and commissioning of the new system control system working closely with MCC suppliers GPS, to get the project delivered to the satisfaction of all parties.

VIEW PDFMynydd Llandegai WTW was expanded to include a CocoDaff plant to address water quality issues from the raw water supply. Following on from a successful Siemens PCS7 control system migration project towards the end of 2009, OSS were contracted to extend the control system to include a number of intelligent MCCs and Profibus instrumentation networks. The new plant was successfully commissioned in isolation before being integrated within the mains works simply by adding the new Profibus networks to the existing AS controller. The project was a great demonstration of innovative use of technology to mitigate disruption to existing plant operations. A detailed case study can be read here:
