Cross Country Drain

Cross Country Drain Project February 2009.Planning Started: 1995
Construction Started: 2005
Completed: 2009

Napier's $15.4-million Cross Country Drain and Pumping Station officially opened in November 2009, providing significant additional stormwater pumping capacity and creating a new greenbelt along the southern boundary of the city.

The drain is an important infrastructural asset in a city that is comparatively flat and low-lying. The system is designed to provide drainage capacity for future city expansion.

Land was purchased for the project, and 230,000 cubic metres of soil excavated to form the 4.3 kilometre long open drain. More than 100,000 cubic metres of excavated material was used to build bridge embankments and the on and off ramps for the Meeanee interchange of the Napier-Hastings Expressway.

The drain runs east from Taradale, downstream of the expressway, through Meeanee to Awatoto, with pipelines crossing Te Awa Avenue, the main rail line and state highway 2, and water being pumped to the ocean. The discharge basin is up to 30 metres wide and 200 metres long, with three discharge points.

The pump station at Te Awa Avenue is equipped with three large pumps, as well as a standby pump and three turbo diesel generators. The system is capable of pumping 10 cubic metres per second, which equates to emptying an average home swimming pool in around two seconds.

The Cross Country Drain also increases security for Napier's stormwater system by connecting with other linear drains - the County, Plantation and Purimu systems.

In Taradale, which has seen lot of infill housing and new subdivision development in recent years, most of the stormwater feeds into the Purimu drainage system. The new Cross Country Drain takes the pressure off the Purimu drain on the western side of the city.

The new open drain also reduces the flooding risk in existing areas such as Pirimai and other parts of Napier and provides capacity for urban growth within the city's boundaries.
