On-Site Wastewater Systems

On-site wastewater treatment and effluent disposal requires specific design to suit the nature of the waste, the site and regulatory constraints.  Further to our experiences with wastewater disposal in Northland's soils and environmental sensitivities since 1981, we keep up to date with technology advances, new products and tightening environmental rules, to provide sustainable cost-effective soluitions.

We have assessed well in excess of a thousand residential sites, schools, motels and marae.  We have also helped establish wastewater management systems for industrial processing plants, including recently from some of the best things in life - oysters, honey and chocolate!
