The development of the WoKaS database followed three steps: (i) identification of karst spring locations across the globe; (ii) sourcing for discharge observations of the identified springs; and (iii) evaluation of collected datasets, which included technical validation and quality assessment. The workflow of these steps is illustrated in Fig. 1. Fig. 1 Workflow of the karst […] More

Global model To assess the global potential of SPHS, our methodology integrates five critical components, which are: topography, river network and hydrology data, infrastructure cost estimation and project design optimization. SPHS project suitability mainly depends on the topography, distance to a river and water availability, which together determine the technical potential. Additional contextual factors, such […] More

Engineering approaches to wastewater treatment must aim for more than improved efficiency. Water is essential to any form of life on Earth — we need enough of it and of the right quality. This is so much at the core of sustainability that we have written about it in previous editorials (Nat. Sustain. 1, 151–152 […] More

Prevalence of E. coli The prevalence of E. coli and total coliform colony-forming unit per milliliter (cfu mL−1) is presented (Table 1) along with in-situ parameters such as pH, electrical conductivity (EC), total dissolved solids (TDS), oxidation–reduction potential (ORP), salinity, and temperature. E. coli in the river ranged between 19,467 and 76,600 cfu mL−1, which is an […] More
