Lacey repairing leaky wastewater treatment tank

OlympianJanuary 3, 2014 

An underground wastewater treatment tank in the Avonlea Park area is leaking.

Lacey Public Works discovered the leak during a routine inspection. The tank is the size of a typical septic tank. The treatment material is widely used to neutralize odor from wastewater, and has high nitrogen content, similar in composition to fertilizer. In certain concentrations, the product could be classified as “Class D”, the lowest toxicity classification that exists.

The city is taking immediate steps to contain the leakage and isolate the affected soil. The leak poses no public health threat to residents or visitors to the park.

Mitigation work will include the excavation of the tank and surrounding soil, which is expected to last approximately two weeks.

Sewer services are not expected to be impacted.
