MASERU- the water and sewerage company (WASCO) found reports of the discovery of worms from its customers’ tap water in the capital city during the Christmas holidays. This was made known at the press conference held at their premises earlier today.
According to the Laboratory Manager WASCO Mpho Mokoatleng some of the reports were from Old Europa and isolated cases from other areas of Maseru. However, the case was addressed and visits were made for investigations and remedial actions.
“We established that larvae of midge fly (Chironomid), commonly known as bloodworms were present at some of the customers’ tap water at the areas indicated. Midge flies live and breed in moist areas or in the water directly”, Mokoatleng revealed.
He further articulated that it is as they received more complaints from various areas of Maseru that they realized the problem is unconfined.
“Then we started doing deep researches which showed that our Mpilo reservoir was the access point for the midge fly which then lays eggs in water; the reason being that a number of activities including equipment testing and maintenance could have exposed the Mpilo Reservoir to unusual access by midge flies” he exposed
He said after their findings, they took remedial actions immediately. It included draining and cleaning of the distribution system of the affected areas and flushing and cleaning one of the main service reservoirs at Mpilo.
“We continue to consult other water utilities who have experienced this challenge on other countries to ensure that there is no repeat and to share experiences”, he noted.
Conclusively he assured customers that the water supply by WASCO is perfectly safe for all domestic use.
“Our Laboratory continues to closely monitor water quality and our water remains complaint with all microbiological, chemical and physical specifications in line with the World Health Organization (WHO) standards. However, we still encourage customers to boil/filter water before drinking it.”
