Water and Energy

Energy-efficient water management and energy production from waste water or the waste products resulting from the treatment are the central topics of the working group. Wastewater treatment requires about 35 kilowatt hours of electricity per year per connected inhabitant. Rising energy prices, increased cost pressure and targeted CO2 reduction make energy efficiency for

wastewater treatment plant operators a major issue. Energy production from waste products such as the use of digester gas for combined heat and power plants are measures to reduce the electricity costs of wastewater treatment plants and at the same time make good use of the waste products.

Reference project

Sewage treatment for a hotel at Galapagos.


06/2018
Galapagos

The Galapagos Islands are famous for their unique wildlife. Yet its habitat is at risk due to the increasing number of tourists and inhabitants on the archipelago. Decentralised wastewater treatment plants are now helping to protect the fragile ecosystem of the archipelago.

In the midst of paradise, only a few metres from the turquoise blue Laguna Las Ninfas, where mangrove trees grow rampant and seals circle the waters, there is a quiet chugging sound. This comes from four large tanks, well concealed under the wooden terrace of a hotel, right by the pool and the guests’ sun-loungers. “This will safeguard our future”, says hotelier Juan Pablo Larraga Herrera proudly as he points to the plant. The wastewater unit has been running for a good year and half in the Hotel Fiesta, which is one of the largest accommodations on the Galapagos Islands with 30 rooms. “Our guests come here to enjoy the unique nature and animals of our archipelago”, he adds. “So we have to protect these.”

The wastewater treatment unit, which is innovative on the Galapagos, is part of a pilot project for sustainable water management on Santa Cruz, the second largest and most populous island in the archipelago. This step into the future was set up ATB Water from Porta Westfalica, supported by EUR 198,000 from DEG – Deutsche Investitions- und Entwicklungsgesellschaft as part of the develoPPP.de programme of the Federal Ministry for Economic Cooperation and Development.

“Until now most water on the Galapagos islands has not been reprocessed because there is no centralized treatment plant on Santa Cruz”, explains ATB Project Leader Thomas Gester.

Wastewater seeps away, almost untreated, into the lava rock and through the porous subsoil into the sea, or it is discharged directly into the Pacific Ocean.

This endangers not only the scarce freshwater resources for humans but also the world of sensitive ocean dwellers: more than 500 species of fish, including over 50 species of shark and ray, mussels, snails and starfish, as well as turtles and sea iguanas, sea lions, seals and marine birds, which are exposed to the environmental pollution caused by untreated sewage..
