Wastewater Treatment Plant Maintenance Services
While maintenance keeps your system running, when paired with our 24/7 remote monitoring it
ensures your system remains efficient, compliant, and reliable—keeping it optimised and operating
at reduced operational costs.
Why Maintenance Matters
Wastewater treatment systems rely on living biological processes to function correctly. Like any essential system, regular care ensures consistent performance,
prevents failures, and protects surrounding water resources.
For larger wastewater treatment plants, maintenance is no longer optional. It is a regulatory requirement under the Department of Water & Sanitation, making professional oversight essential for both compliance and peace of mind.
Mandatory Maintenance: What the Regulations Require
The Department of Water & Sanitation (DWS) requires mandatory maintenance for all wastewater treatment plants processing 20 m³/day or more. Under Regulation 3630, this means:
Maintenance, monitoring, and reporting must be carried out regularly
All maintenance must be performed by competent, qualified personnel
Approved maintenance plans must be in place before operation
Accurate service records must be maintained for regulatory compliance
Failure to comply can result in operational risk and regulatory consequences.
Maintaining a smaller household system?
Calcamite Maintenance Services
Operating from Pretoria with national reach, Calcamite provides a full, engineer led maintenance service designed to keep your plant compliant, efficient, and operating reliably overseen by qualified engineers and professional process controllers.
We have partnered with leading technology and engineering specialists to deliver a fully integrated maintenance solution.
Smart Remote Monitoring—Your Plant, Connected 24/7
With remote monitoring and control capabilities, your plant is continuously connected to our central oversight hub via the cloud
—providing real time visibility into system performance and operations, without needing to be on site.
Proactive vs. Reactive Maintenance
Our systems use predictive analytics to identify potential equipment failures before they happen. If a pump shows signs of strain, we receive an alert instantly, often before you notice any change in performance.
Real-Time Compliance & Reporting
For clients with environmental discharge requirements, our system provides continuous data logging, giving you a complete audit trail of plant operation at all times, including inflow, outflow, and mechanical equipment uptime.
Reduced Operational Costs
By reducing the need for emergency callouts, remote monitoring lowers the total cost of ownership for your facility.
Remote Optimisation
Our engineers can fine tune your plant s performance by adjusting internal recycle rates remotely and in real time, maximising efficiency without a technician needing to visit the site.
Leading the Way in Sustainability
AVEVA is a global leader in industrial software, and its annual Sustainability Impact Awards recognise innovation in infrastructure and resource management on an international stage. Calcamite was named a finalist in the 2026 awards recognition of our mission to bring world class Smart Water technology to decentralised systems across South Africa
In-House Laboratory & Testing Facilities
To complement our remote digital oversight, Calcamite operates specialised in house laboratory services. This enables rapid, precise testing of critical chemical
parameters, including COD, phosphates, ammonia, and nitrates.
By combining real time remote data with regular laboratory analysis, we can fine tune your plant s biological health. For you, this means optimised biological
augmentation, improved effluent quality, and the confidence that your system is being managed by both cutting edge AI and expert liquid chemistry.
What Our Maintenance Service Includes
Our comprehensive service covers every aspect of plant health and compliance:
Remote monitoring
Daily remote monitoring of mechanical and electrical equipment
Assessments
Annual plant assessments and services to optimise plant performance, including measurement of critical chemical parameters: COD, conductivity, ammonium, nitrate, TSS, and pH
Reports
Clear monthly performance reports covering inflows, outflows, and mechanical and electrical downtime.
Maintenance
A tailor made maintenance plan designed for your specific plant type and capacity
Not a Calcamite Plant? We Can Still Help.
Calcamite offers standalone plant assessments for any packaged wastewater treatment plant, regardless of who supplied it. Each assessment includes measurement of critical chemical parameters (COD, conductivity, ammonium, nitrate, TSS, and pH), giving you a clear picture of your plant s current health and compliance status.
It s a practical first step for any plant owner who needs to understand where they stand before committing to a full maintenance plan.
What to Expect at Household Scale
Maintaining a Calcamite system at household scale is simpler than maintaining a swimming pool because you don t need to clean it.
Your system is designed to look after itself. All you need to do is:
- Check that the blower and pump are running
- Avoid harsh or toxic chemicals such as bleach or drain cleaners, which can harm the beneficial bacteria that keep your system healthy
For routine cleaning around the system, OptimusBio manufactures a range of biodegradable, Global GreenTag Certified products that use naturally occurring
bacteria to break down organic waste to make it safe for your system and the environment.
