Brown Drainage and Construction

Recent Projects

We are experts at the dirtier, more difficult jobs - we have improved our team leadership and have incentives to keep our sites tidier!

Almost every house in Taupiri is now on a main sewer system bypassing all the existing septic tanks.
As we approached the end of this massive contract that started in September 2006 we are thrilled with how our team had grown, while maintaining quality.

The key to the success of the job has been maintaining good communication between all parties - Auckland Consultants, Council Representatives, Residents and our team while also advancing the works programme with variations and extras.
