TREATMENT OF SEWAGE

Detail In U.S. Plan For Christchurch

The United States consulting engineers who are preparing the plans of the Christchurch Drainage Board’s sewage treatment plant have showed great attention to detail, extending it beyond the actual construction and engineering problems to that of landscaping the area so that it will look more like a park than a sewage works. A report of Mr D. L. Steven, the board’s engineer, who has been working with the consultants in the United States, mentions that the engineers even found from New Zealand details of the soil at the site and had drawn up a list of plants and shrubs which it was expected would grow well under the local climate.

Mr Steven says the plant embodies what the consulting engineers believe to be the most up-to-date principles of sanitary engineering design. In the last three years, he had visited many plants in the United States and discussed with design and operating engineers the problems which could arise. The operating difficulties which could arise in a plant were many and varied, and in the design of the Christchurch plant every effort had been made to meet all the difficulties arising from the treatment of sewage and associated wastes.

Wherever possible, the design has been based on equipment known to be available within the sterling area.
