Onsite Wastewater
On-site wastewater systems provide treatment and disposal of wastewater within the property, it is important that these systems are designed to avoid risks to public health and the environment. The Marlborough Sounds environment creates many challenges for the treatment and disposal of wastewater. Sometimes working outside the standard NZS1547:2012 to find a suitable solution we can provide independent advice and design to address your onsite wastewater needs. We also review existing systems for renewal and resource consents.

Jetties
Jetties come in a range of styles depending on the location and environment. We can assess the best type of jetty for your site and needs, from standard fixed timber jetty to floating pontoons and aluminium gangways. We can also undertake structural condition assessments for existing jetties to assist in the renewal of your resource consent.
Boatsheds
Building your boatshed in the Marlborough Sounds is not guaranteed, you must first gain approval through the resource consent process.

Slipways
To get the best use of your boatshed a slipway (ramp) is a great way to access your boatshed from the sea. We have designed a number of slipways, let us use our experience to help you to find the perfect fit.
