Recent Projects

Enviro Metsi is continuously looking for ways in which to assist municipalities and other Water Services Authorities with the daunting task that they face when it comes to managing, operating and maintaining the Water and Wastewater Treatment Facilities they are responsible for.


Some of the projects we were recently involved with includes Drinking Water Quality Management (Blue Drop Support) for Stellenbosch Municipality, the Refurbishment of Mechanical Equipment at Grabouw WWTW, Training of Process Controllers for both Oudtshoorn Municipality and the Department of Public Works and the Repair, Operation & Maintenance of Water and Wastewater Treatment Works for the Department of Public Works.

Drinking Water Quality Management Programme for Stellenbosch Municipality


Based on our previous involvement at Stellenbosch Municipality, Enviro Metsi was approached by CSIR: Stellenbosch to once again become involved in the monitoring of the quality of potable water being supplied by Stellenbosch Municipality while assiting the municipal officials in the management of their Blue Drop Programme

Upgrading of the Grabouw Sewage Treatment Works: Mechanical Equipment


For this project Enviro Metsi joined forces with Circuit Water Engineering Equipment to refurbish 3 clarifiers and replace 1 Mixer (anaerobic zone) & 4 Aerators (aerobic zone).  Circuit Water supplied the equipement while Enviro Metsi managed the project and dealt with the installation of the new equipment




Training of Officials from Oudshoorn Municipality on Water and Wastewater Treatment Process


Enviro Metsi recently concluded a training project for Oudtshoorn Municipality where 7 Unit Standards worth of training was provided to 10 learners.  As the learners are employed on a full-time basis the project entailed facilitation for 3 days followed by a 3 week period where learners completed workplace assignments and their Portfolios of Evidence.     





NQF 2 Training for Department of Public Works: Western Cape

(National Certificate: Water & Wastewater Process Control)


In order to empower the Department's Process Controllers, Enviro Metsi presented a 30-Credit course to the Department of

Public Works' personnel over a 3-month period. Theory was covered in 3 block sessions after which the specific Treatment Works where the personnel work was visited to ensure the Process Controllers were able link their newly acquired theoretical knowledge to the practical aspects experienced in the field.





Updating Water Safety Plans for Stellenbosch Municipalty


Water Safety Plans were introduced as a holistic approach to Drinking Water Quality Management in South Africa. It provides a systematic and transparent approach to ensure the consistent provision of safe water with a clear focus on public health.


As Stellenbosch Municipality had existing WSP’s, Enviro Metsi assessed the existing plans, each of their systems in terms of its physical conditions as well as the water quality applicable to each of the systems and provided Stellenbosch Municipality with a new set of Water Safety Plans. These were then combined into Management Plans where specific sections of the various documents were extracted and used to develop Management Tools that apply to specific departments within the Municipality. This enables specific people to focus on the sections of the WSP's where their input is required without getting distracted by details that don't specifically apply to the section they work in.






Drinking Water Quality Management: Stellenbosch Municipality


Stellenbosch Municipality awarded the contract for their Drinking Water Quality Management to Enviro Metsi in 2013.  This included sampling of potable water throughout the Stellenbosch area, the

evaluation of the results obtained and providing input into Water Quality Management and the Blue Drop Programme.



Repair, Operation & Maintenance of Helderstroom & Buffeljagsrivier WTW and WWTW


The Department of public works initiated the so-called “RAMP contacts” for a number of the facilities under their control. These contracts start off with a repair phase during which the plants are repaired to their original design status or even upgraded to cope with current conditions. Running concurrently with the repair phase is the Operation and Maintenance phase of the project. This phase is aimed at ensuring that specialist contractors operate the facilities in such a way as to while maintaining the facilities in the newly repaired state.


Due to our successful track record in the Operation, Maintenance and Management of Water and Wastewater Treatment Works, Enviro Metsi was contacted by Botes & Kennedy Manyano, who were involved in the civil works on these plants, to be involved as Specialist Subcontactor.


Helderstroom Water Treatment Works (Villiersdorp) treated about 3 Ml/d through a conventional Water Treatment Works while Buffeljagsrivier (Swellendam) had a capacity of about 150m3 of water per day – treated by a “Package” Water Plant,  The effluent from these facilities are treated by means of activated sludge plants.




Repair, Operation & Maintenance of Waterval Bulk Supply & WWTW


This is another “RAMP” contract. Enviro Metsi was appointed as the

main contractor to manage the entire project (including upgrades) while operating and maintaining the works Waterval Prison (Utrecht) receives its water from a Bulk Supplier, but the sewage needs

to be treated in a Bio-filter Plant.
