Municipal Water Treatment

Municipal water treatment infrastructure, whether it is government or privately owned, requires maximum-efficiency plants to create drinking water, treat wastewater (sewage), or re-use wastewater in an environmental, economic and sustainable way.

As part of the world’s largest water services company, Veolia Water Technologies South Africa offers everything necessary to achieve this for both large and small scale upgrades and new projects within the municipal water treatment market.

Municipal water treatment is divided into two main categories:

Municipalities are typically responsible for wastewater treatment and potable water creation on large scale, while smaller private organisations - such as mines, holiday resorts, etc. - have begun to see the benefits of small-scale wastewater treatment and potable water generation.

Veolia South Africa, backed by the global Veolia Group, caters for all these requirements.

Solutions are available for new and existing municipal water treatment systems

Whether for a new mine camp, gated community, holiday resort or large-scale municipality, Veolia tailors plant specifications, designs and operations to suit the available budget, desired treatment standards, influent (water source) quality and the required treatment volumes.

For older, existing municipal water treatment plants, Veolia offers a series of technologies and design philosophies that improve treatment standards, significantly boost plant capacity and reduce operating expenses.

With dedicated project teams that manage turnkey plant design, construction, commissioning and operations, Veolia ensures complete water infrastructure solutions from a single-source supplier. This allows us to even combine municipal water treatment projects with industry, enabling a unified approach to better water resource management for all.

Water infrastructure and Service, Value and Responsibility

Through above industry-standard service - which includes state-of-the-art technologies and a greater municipal water treatment understanding - we create value for our customers, their consumers and for the environment. We take on the responsibility to help ensure that nothing of value is wasted, and that water infrastructure systems are as environmentally responsible as possible.

Veolia can reduce a municipal water treatment plant's reliance on the national energy grid with upgrades to recover electricity from sludge digestion processes. With a strong focus on R&D, Veolia aims to use biogas, heat and energy recovery to optimise municipal water treatment plants to a point where cleaner energy is fed from the water infrastructure into an energy grid.

We are committed to improving the local water infrastructure, and have helped our customers with a series of services that range from world class treatment process designs, to BOO (Build, Own, Operate) and BOOT (Build, Own, Operate, Transfer) financial arrangements.

Municipal water treatment upgrades success

Walvis Bay Municipality - Namibia

This municipal water treatment plant upgrade boosted the city's wastewater capacity from 2 to 6.5 mega litres per day while using existing civil works to house newer-generation, more efficient trickling filter technology.

By using existing structures, this upgrade method was favoured for its lower cost, faster implementation and significantly improved capacity, discharge standards and ease of operation.

Municipal water treatment project success

Durban Water Recycling Project - KwaZulu-Natal

The Durban Water Recycling Project is Veolia's flagship municipal water treatment project which provides major benefits to the city's eThekwini Municipality. It reduces water pollution generated by the area's population, while generating a lower-cost resource for industry.

A BOOT (build, own, operate, transfer) project, the plant treats and re-uses domestic and industrial wastewater with innovative and customised technologies developed specifically for this large-scale water infrastructure application.

Approximately 47.5 million litres of wastewater per day enters the plant for treatment to within near potable standards. The resulting water is then sold to the city's industrial customers, Mondi and SAPREF, for use as process water - alleviating strain on the city's fresh water infrastructure.

This feat of municipal water treatment engineering benefits all parties involved, including the environment. Industrial customers' operating costs are reduced due to the decreased demand for drinking water, the municipality can redirect this surplus water to other users, and no harmful effluent is released into the environment.

Drinking water infrastructure project - Near Palapye, Botswana

This Veolia-designed, built and commissioned municipal water treatment plant removes ground water hardness and dissolved salts from borehole water at a rate of 13 200 mega litres per day.

The hardness of the water was causing water infrastructure pipes, household geysers and appliances, such as washing machines, to scale, requiring more electricity to heat the water for general purposes and more detergents for washing to be effective.

The plant softens the water using Veolia-patented Multiflo™ high efficiency clarifier technology. Lime is injected into the water before the clarification process, and lamella settlers retain flocculants, allowing clarified water to flow through the plant. Collected sludge is concentrated in a thickener, pumped into a solar drying dam and then taken to a landfill behind the plant - completing the flow path through the water infrastructure plant.

The clarified water is chlorinated and then directed into the region's municipal water treatment's supply pumps. The quality of water produced complies with the BOS 32:2000 drinking water standard.

Mine site water infrastructure project - Lumwana Mining Company

A packaged plant was designed, supplied and installed as part of the construction of a new mine. The plant, operational since early 2006, produces 0.35 mega litres of drinking water per day for distribution into the mine camp's water infrastructure.

A man-made dam supplies this water infrastructure project with raw water for clarification. After this, flocculants and chlorine are added, and the pH is corrected. It is then stored in a clarified water storage tank, from where it proceeds through two trains of sand filtration followed by carbon filtration. After this stage, the pH is corrected once more, and more chlorine is added. The clarification, coupled with the pH correction, allows the suspended solids to be removed while the sand and activated carbon filters remove colour and odours from the water.

As the final step, before distribution to the mine camp's water infrastructure, disinfection is required to avoid contamination by micro-organisms.

No matter the objective - whether it is to improve capacity of optimise for efficiency - Veolia is experienced in designing municipal water treatment plant upgrade procedures that fall within budgets and realistic timelines. Enquire now or call us today for more information.
