Waste water upsets residents, pollutes

Update: May, 21/2015 - 09:32

DA NANG (VNS) — For six years, a dreadful stink has upset residents living near a channel carrying waste-water from the Phu Loc waste-water treatment station in the city's Thanh Khe District.

The smell is blamed on poor treatment of waste water at the station and failure to commence a project to upgrade the plant.

Residents have attempted to block the smells themselves by stuffing sand bags and soil in water outlets.

Director of Da Nang Waste-water Treatment Company, Mai Ma said the Phu Loc treatment station was only built in 2008.

Ineffective treatment

It was supposed to break down sewage and waste with microbes and air (anaerobic treatment), but it did little to stop foul smells pouring from the plant.

"We installed a de-odorising system during the last stage of treatment, but the situation did not settle down," Ma said in talks with residents.

He said that in 2011, the company had built a chemical spray system and screen to try and disguise the smell. The city also built a 200 metre pipeline to carry waste water from Phu Loc station to Da Nang Bay.

However, sand from the sea slowed the flow and caused stagnation of waste water in the channel.

Ma said that as a temporary solution, the company would spray chemicals to eliminate the smells.

Meanwhile, waste-water from the Phu Loc channel has heavily polluted a large area close to seaside resorts and public beaches in Thanh Khe and the neighbouring Lien Chieu districts.

The city has now allocated VND137 billion (US$6.5 million) for the first stage of an upgrade to Phu Loc station, starting from the end of this month.

Director of the city's department of natural resources and environment, Nguyen Dieu, said the city had called for investment in an additional waste-water treatment station in the area besides the existing Phu Loc plant.

Total investment in the new station is expected to be VND304 billion (US$14.5 million).

The department will also develop a waste-water collection pipe system along coastal road Nguyen Tat Thanh and upgrade waste water treatment station in Lien Chieu District. — VNS
