Location
The EWSC Main Laboratory is the nucleus of the quality assurance function of EWSC. It is located at Mountain View along Buntfu Road, before Mountain Inn. The lab’s geographical coordinates are: S 26?20.131’, E 31?08.977’. The EWSC Laboratory provides water and wastewater testing services for EWSC and other private customers which include wet industries, agro-businesses, private borehole, etc.
EWSC Lab has three in-house sampling programs, i.e. potable water (raw, treated, distribution), wastewater (influent, effluent, river water) and industrial effluent. All these are scheduled by the Laboratory Information Management System (LIMS) which dictates from a day-day basis what samples have to be taken where and what analyses done thereof.
Potable water monitoring program: Quality Inspectors collect samples daily from all EWSC Potable Water Treatment Plants. Samples are collected at key points along the potable water value chain, i.e. raw water from dams and rivers, treated water from plants, distribution reservoirs and at customer taps. The collected samples are then timely delivered at the laboratory for analysis using standard methods. The purpose of the monitoring is to safeguard the integrity of the water from source to end user thereby protecting public health.
Wastewater monitoring program: Quality Inspectors also sample influent and effluent from all of EWSC wastewater treatment plants. In addition EWSC also monitors the effect of its effluent in the receiving streams and rivers by sampling upstream and downstream its effluent discharge points and conducting analysis as defined by the Eswatini Environment Authority’s (EEA) Water Pollution Control Regulations (2010).
Trade effluent monitoring program: EWSC regularly monitors discharges from wet industries which deposit industrial effluent into its sewer. This is meant to determine the pollutant load in the industry discharges in order to ascertain whether the receiving plant’s design capacity will be able to treat the effluent and reduce the pollutant load to acceptable discharge standards as defined by EEA’s Water Pollution Control Regulations (2010).
