We provide expert service across the scale range, from adding one new house to thirty-plus sections as well as commercial builds.
We can supply and install all of the water and drainage services required and liaise with engineers, services such as power, gas and Chorus, as well as councils to complete our clients’ projects. City councils and Wellington Water inspect and certify all our work.

Drainage
We install a range of drainage sizes and materials to meet requirements – from PVC, HDPE and concrete pipes to large manholes. We also design and install soak pits, water retention systems and septic systems.

Consultation, design, and install
Mana Plumbing can take our clients from the planning stage right through to the final sign off. We will carry out on- site consultations and then fully design civil drainage and water reticulation systems to suit the individual needs of the project. We then arrange the approvals needed and complete the installation of services.

Traffic Management
We can provide traffic management solutions to satisfy all requirements as needed during our projects.

Subdivisions
From drainage to water reticulation, we can install all services required for a subdivision. We will also liaise with services such as power, gas, and Chorus, as well as city councils and other authorities, to fully complete a project.
