THE BEST WATER SAFETY PLAN AWARDING CEREMONY IN ON WORLD WATER DAY 2018

Prepared By Water Safety Plan Advisory Unit National Water Supply & Drainage Board Sri Lanka

April, 2018

Introduction

Water Safety Plan (WSP) is a proactive risk assessment and management approach covering the whole water supply system from catchment to consumer. Recognizing the important role of WSP in ensuring the safety of drinking water, South-East Asian Region (SEARO) of World Health Organization (WHO) supports countries in the region to implement and institutionalize WSPs as a normal practice.

There are 339 WSSs operated in Sri Lanka by the National Water Supply and Drainage Board (NWSDB) and covers almost 38% of the total population, i.e. 21 Millions. In addition, the rural WSSs operated by the community based organizations (CBOs) provide pipe water supply to almost 10 % of the population. As per the master plan of WNSDB, the pipe water supply coverage shall be increased up to 60% by year 2020. Simultaneously, the WSP team of NWSDB headed by the Additional General Manager (Sewerage) has developed its strategic plan to implement WSPs in all WSSs by the end of Year 2020.

Implementation of WSPs in Sri Lanka commenced through a training of trainers’ workshop, which was held by the WHO in 2013. Since then, presently more than 110 water supply schemes under the NWSDB are being implemented. The WSP applied Water Supply Schemes (WSSs) cover almost 60% of the total pipe borne water supplied population in the country.

As WSP success and sustainability may rely on the rewarding process to appreciate the commitment of the operational staff the NWSDB has decided to award the best three WSPs out of over 100 WSPs implemented in the country by January 2018.

Hence, a competition to select the best WSSs, which has implemented WSP, has been conducted for the first time in Sri Lanka to mark the World Water Day 2018.

The basic audit guidelines stipulated by the WHO has been followed in the evaluation in addition to the observations from the previous audits done by the WHO experts, WSP Master Trainers and Champions.
