SUMMARIZE THE FOLLOWING PARAGRAPH IN ONE OR TWO SENTENCES
6 Ten years ago, donor countries
contributed part of the funds to construct
water refineries and sewage treatment
plans, and connect the sewage networks
of residential areas to these plans. Once
in operation, these improvements were
supposed to reduce pollution by 50
percent. However, the plants are not
complete. Al Mays believes the extent of
the problem is such that facilities to treat
household solid and organic waste are
needed, as is a law obliging companies to
build their own plans to treat waste.
