Water management solutions provider Sewtreat has successfully completed two “ground-breaking” projects at fast-moving consumer goods retail giant Pick n Pay’s Eastport Logistics Park, in Kempton Park, Gauteng.

The projects involved the implementation of innovative rainwater harvesting and biological water treatment systems, resulting in significant cost savings and impressive payback periods.

The first project is the installation of a rainwater harvesting and treatment system

Sewtreat's rainwater harvesting system collects and treats 300 000 ℓ of rainwater for use in the cooling plant.

The system includes a three-million-litre dam for ample rainwater collection, a one-million-litre underground sump for clean and safe water storage, and it enables sustainable water use for the cooling plant.

By using rainwater, Pick n Pay minimises dependence on expensive municipal water sources, promotes responsible water management, and contributes to conservation of the environment.

The system saves over R2.5-million a year and has a payback period of only 22 months.

The second system implemented by SewTreat is a biological water treatment system, which processes and reuses over 150 000 ℓ of wastewater from the on site truck wash bay.

With a “state-of-the-art biological water treatment plant”, the system ensures effective treatment and purification, and the treated wash bay water can be reused on site, minimising water consumption.

The system optimises wastewater treatment, reduces environmental impact, and adheres to regulatory requirements. The system saves over R2.2-million a year and has a payback period of only 14 months.

Ongoing Operation, Maintenance

Sewtreat provides comprehensive operation and maintenance services for the implemented systems, ensuring long-term efficiency and reliability.

The company continuously monitors and optimises the performance of the systems, and its team of experienced professionals provides reliable support whenever needed.

Sewtreat's completed projects at Pick n Pay's Eastport Logistics Park demonstrate the company's commitment to innovative and sustainable water management solutions.

By choosing Sewtreat's rainwater harvesting and biological water treatment systems, Pick n Pay has achieved remarkable cost savings and payback periods. Additionally, with Sewtreat's ongoing operation and maintenance services, businesses can achieve significant savings and contribute to a greener future.

The two projects at Pick n Pay Eastport Logistics Park together result in combined yearly savings of over R4.7-million.

These savings are substantial and highlight the economic benefits of investing in sustainable water solutions.

Further, the water conservation impact is equally impressive, with yearly water savings amounting to 238-million litres, which is equivalent to 95 Olympic-sized swimming pools.

Alternatively, this volume of water can provide 380 000 households with water.

Eastport Purpose

The Pick n Pay Eastport installation is a significant distribution centre located in the north-eastern part of Eastport Logistics Park.

Spanning an impressive 164 000 m2, the facility is strategically situated with direct access from the R21 Expressway, providing convenient transportation routes.

The overall purpose of the Pick n Pay Eastport installation is to streamline the distribution and logistics operations of the supermarket chain.

By having a large and well-equipped distribution centre, Pick n Pay can efficiently manage its inventory, ensure product availability, and facilitate timely deliveries to its stores.

This installation plays a crucial role in supporting Pick n Pay's operations in providing a diverse range of grocery products to its customers while maintaining product quality and freshness.
