Service level agreements
Establishing a partnership for the optimal management of water assets with ongoing process and technical support.
Maximum performance of your water treatment infrastructure
No matter your available resources or expertise to keep your treatment plant running, structural support might still be essential.
The Waterleau SLA program provides unmatched protection against unexpected downtime. Customized to your specific needs, our Service Level Agreement ensures peak performance and optimized operations for your plant.
Case: Optimizing WWTP OPEX
Achieve Significantly Improved Financial Performance with SLA
In a country abundant in energy resources, Nigerian industries largely depend on self-generated electricity powered by CNG, LNG, and diesel.
Through a Service Level Agreement (SLA) with Waterleau, a global brewery with a local production site achieved significant power savings for its wastewater treatment infrastructure, designed and built by Waterleau. Consistent year-on-year electrical energy savings were realized, with one notable exception: a temporary SLA suspension during the 2020 pandemic.
A key driver of these energy savings was the optimization of the aerobic treatment process. Effluent-polishing sand filters and auxiliary systems enhanced the biological treatment process, significantly reducing aeration energy requirements.
Even with an increase in installed treatment capacity, these efficiency gains were achieved by leveraging advanced testing and fine-tuning of adjustable parameters, all while maintaining the highest treatment quality standards.
Maximizing thermal energy recovery
Our audits confirm that nearly 100% of the bio-methane produced is utilized in the boiler house, minimizing waste through flaring. We are currently enhancing the precision of bio-methane production and consumption measurements to enable accurate live reporting.
Continuous OPEX improvement
By implementing our recommendations, the dynamic calamity tank has successfully prevented untreated effluent bypasses, avoiding both lost bio-methane production value and skewed electrical energy savings data. Our consulting and reporting efforts consistently avert counterproductive strategies, such as cost-cutting measures in sludge de-watering, that could inadvertently increase overall OPEX or lead to regulatory non-compliance for the WWTP.
Enhancing Client Competences
Our client has shown commendable diligence in reporting data, attending support meetings, maintaining equipment, and executing our recommendations. Over the course of the SLA term, their in-house expertise has significantly grown. Our continued involvement serves as a vital knowledge base, mitigating the effects of staff turnover and ensuring operational excellence.
