Schinias – Freshwater for Greek coastal area

Figure 2. Schinias SWS configuration has been set up mainly in three parts: (A) Water supply installations, (B) AOP-RO hybrid water treatment unit, and (C) the artificial recharge site, consisting of four wells, three vertical and one horizontal.
Schinias - Freshwater for Greek coastal area

The Schinias pilot is a hybrid application of ASR-Coastal and Freshmaker technologies of the subsurface water solutions. The site of Schinias is a coastal protected wetland linked to a typical coastal hydrogeological system of a Mediterranean region. Additionally, there are seasonal water shortage …

Sufficient and safe irrigation water in Maneadero Valley, Mexico

Sufficient and safe irrigation water in Maneadero Valley, Mexico

Maneadero Valley is a 35 km² coastal alluvial plain in Baja California, Mexico, producing high value crops such as tomatoes and cucumbers for local and export markets. Food production is under pressure because of a shortage of freshwater for irrigation. Overpumping …

Freshkeeper to counteract salinization of water wells

Freshkeeper

Salinization of freshwater abstraction wells and freshwater well fields can be mitigated or even prevented by the interception (abstraction) of the intruding or upconing saline water. This is called the Freshkeeper concept. The principle is that not only fresh groundwater is abstracted, but with a separate filter screen also …

Dinteloord – ASR enables cross-sectorial water reuse

The continuous availability of freshwater of very good and reliable quality is a precondition for modern intensive greenhouse horticulture.  For Dinteloord, the Netherlands, a 260 hectares greenhouse area under development by developer TOM, the freshwater availability was not self-evident. Although the water needs …

Abu Dhabi – ASR for secure drinking water supply

Abu Dhabi – ASR for secure drinking water supply

Abu Dhabi (EAD) produces its drinking water from desalinated seawater from the Arabian Gulf. In case of emergencies, e.g. when algal blooms prevent the intake of water from the Gulf, this system can supply the city with water for a maximum …

Haaksbergen – Reuse of sewage effluent for agricultural water supply

Figure 2: Supplying the Bolscherbeek with effluent from the Haaksbergen sewage treatment plant exceeds the natural basic drainage in the summer period (Photographer: Bas Worm, Waterschap Vechtstromen).
Haaksbergen - Reuse of sewage effluent for agricultural water supply

Available groundwater sources for irrigation purposes are increasingly under pressure due to the regional coexistence of land use functions that are critical to groundwater levels or compete for available water. At the same time, treated wastewater from industries and sewage …

Gotland – Securing freshwater supply on a Swedish island

Wetlands at Gotland island to promote aquifer (groundwater) recharge.
Gotland – Securing freshwater supply on a Swedish island

In the last years, Gotland experiences a severe water crisis that negatively affected tourism and small-scale industries. Water shortages in parts of the island (like Storsudret in the south) hinder the economic development due to strict regulations for building of new …

Coastal recharge to enable potable reuse in Atlantis, South Africa

Indirect potable reuse schema at Atlantis, South Africa, including pre-treatment before and post-treatment after artificial recharge.
Coastal recharge to enable potable reuse in Atlantis, South Africa

The town of Atlantis (South Africa) practices indirect water recycling, of which artificial groundwater recharge forms a major component, for almost 40 years. The Atlantis groundwater scheme provides a cost-effective water supply option in conjunction with strict management controls. The …

Subsurface iron removal – a groundwater treatment option

Pilot setup for in-situ iron removal at Atlantis artificial recharge site, Atlantis, South Africa
Subsurface iron removal - a groundwater treatment option

Clogging of water abstraction wells by (the formation of) iron precipitation is an operational problem worldwide.  In-situ iron removal (ISIR) treats the source of the clogging problems by periodically injecting a volume of ozonated water into the anoxic aquifer. In the aquifer, …
