Water Cycle Restoration
TWM has proposed a methodology for regreening coastal zones up to about 50 km inland. The conceptual design consists of dredging works to restore wetlands and include Eco Engines to purify waste water and build liveable soils. Next to that the plan consists of dry earth moving for the construction of terraces and rock bunds on strategic places for replanting trees. The objective of the works is to increase the available fresh water in the region.
TWM has delivered an alternative design for the planned tidal basin. The design includes ecological sustainable revetments. One of the important objectives of this alternative design is to optimize sequestration of carbon dioxide and combine ecosystem function with renewable energy. This opens up opportunities for a new type of business case.
With reference to Resource Based Dredging, TWM designed an Eco Engine concept. Next to purifying water, contaminated soils can be remediated as well by this Eco Engine. The surplus of biomass from the engine is intended to be used as a biofuel for a power plant. Process water from power plants will be remediated and cooled before it will be disposed back into the river. Currently the concept is being explored with all stakeholders.
Regreening Maasai Land
TWM, as a partner of the Friends of the Maasai Foundation, has on the basis of a step wise approach designed a methodology to regreen north west Kenya and contribute to a sustainable future for the Maasai communities living in this area. The methodology allows for minimum interventions in the first phase, learning and development for all stakeholders and easy upscaling on the basis local needs and available funding.
A municipality in the Netherlands with a strong agricultural identity has plans to develop an area of 77 hectares currently mainly in use as farm land. TWM has, on the basis of several stakeholders workshops, proposed a methodology how the area can pro-actively be developed as an integrated area where water safety, climate change, sustainable farming and recreation can all be combined in an innovative way within a long term framework to prevent climate change.
