Dear Sirs


The registered suppliers are requested to comply with the following rules and regulations stipulated by the National Water Supply & Drainage Board in respect of quotations.

Please use separate covers for different quotation numbers. Quotations may be placed in the Box provided for the purpose at Supplies Section by Registered Post.
  2. Wherever the offered item is imported, the Country of Origin and Brand Name, if any must be indicated.
  3. Samples and literature of times offered, wherever applicable, shall be provided.
  4. Suppliers who fail to quote for three consecutive occasions in response to the enquiries, will be deleted from the Register of Suppliers.
  5. Normally, quotation will be called from the registered suppliers. But the Board reserves the right to obtain quotations from other suppliers as well whenever necessary.

  7. Bid Bonds
    1. In the case of quotations where the value exceeds Rs. 100,000.00 a Bid Bond should accompany the quotation to the value of 1% - 2% of total value. Bid Bond should be valid for 90 days.
    2. Collective Bid Bonds are permitted provided supplier agrees to such Bonds being retained by the Board until all the quotations covered by such Bonds are finalized.
    3. However, collective Bid Bonds should not be sent in respect of quotations where closing dates fall on different dates.
    4. As soon as quotations are finalized, Bid Bond will be returned to suppliers with the exception of the successful suppliers to whom the Bid Bond will be returned after a Performance Bond is received.

    1. Performance Bond will be required from the successful supplier to a value of 10% of the total value on any purchase exceeding Rs. 250,000.00. Performance Bond should be valid for 90 days unless otherwise specified on award.
    2. The successful supplier on each quotation will be informed by way of Letter of Award (Applicable only to quotation where the value exceeds Rs. 100,000.00 and a Purchase Order for value less than 100,000.00) on receipt of the Letter of Award the successful supplier should make immediate arrangements to submit the Performance Bond.  And the bid bond will be released thereafter.
    3. In the event of the successful supplier failing to submit the Performance Bond after receiving the Letter of Award within the stipulated time, the Bid Bond will be forfeited if the supplier fails to supply the items within the delivery period to compensate for damages caused to the Board.
    4. On receipt of a Purchase Order/Letterof award, the successful supplier should comply with the requirements specified therein such as delivery of goods to the required specifications and standards.
