Suppliers and service providers working in water treatment equipment, supplies and services will find every Water Treatment Equipment, Supplies and Services tender we have tracked on this page, from short-notice RFQs to formal, gazetted Tender Bulletin calls.

Tenders in this category ask suppliers to quote on water treatment equipment, supplies and services - anything from once-off supply contracts to multi-year service agreements, depending on the issuing organisation's needs. Requirements, BEE and compliance criteria differ per tender, so review each listing individually.

Based on the tenders we have tracked, Department of Public Works, City of Cape Town and ESKOM are among the most frequent issuers; and activity is concentrated in Western Cape, Gauteng and KwaZulu-Natal.

Each listing includes the tender or bid number, the closing date and time, and a link through to the original tender document where one is available, so you can review the full scope, specifications and submission requirements before applying.

To find out more about a specific listing, open the tender and review the attached documentation, then contact the persons named in the document to submit your water treatment equipment, supplies and services tender. Have a water treatment equipment, supplies and services project of your own? Submit a Request for Quotation via our Send Us Your Tenders page and we will distribute it to our network of subscribers, who will respond directly with quotations so you can choose a suitable supplier.
