Three Waters Infrastructure Contractor
Water, sewer and drainage utilities construction
As a three waters infrastructure contractor, we take responsibility for contributing to the provision of secure, dependable drinking water, efficient wastewater collection and treatment, effective stormwater drainage, cleaner harbours, healthier waterways, and protection from flooding.
Groundworks is determined to uphold a standard of excellence across our water, sewer and drainage construction services, and support healthier Wellington communities. We strive to develop innovative approaches that deliver cost effective, resilient and reliable solutions.
We have a strong capability across all three waters connection, upgrade and renewal projects. We work with both private and council clients, and operate across the Wellington region.
Our three waters services
Water reticulation
We dig and lay mains and laterals for potable water reticulation systems. As water connection contractors, we install lateral connections from water mains to residential houses. At the subdivision level, we dig, lay, pressure test and chlorinate water mains in HDPE or PVC pipe for stretches of road.
Wellington Water – approved contractor
We are approved to undertake water main cut-ins for Wellington Water. This might involve from a live tap for a residential connection, to developing a network shut-down plan, draining a section of water main, and installing a new pipe for a fire main, subdivision or commercial building.
Wastewater
Our wastewater contracting work includes renewals of existing sewer pipes, connecting laterals, fusion welding, over-pumping and dewatering. Or we can construct completely new wastewater systems, including pump systems and chambers. We work with wastewater pipes manufactured from PVC, HDPE, concrete, steel, and other types of material.
Groundworks is committed to delivering sanitary and efficient wastewater systems that do not infiltrate into sensitive natural environments.
Stormwater
Our holistic expertise covers all aspects of public and private drains. We focus on delivering innovative approaches that provide cost effective, resilient and reliable stormwater solutions.
Groundworks undertakes renewals or new projects, installing sumps, chambers, pump stations, rain gardens, retention tanks, dewatering, and other treatment processes.
We respect surrounding sensitive natural environments in our projects, striving for cleaner harbours, healthier waterways, and protection from flooding.
We are determined to uphold a standard of excellence for healthier and safer communities within the Wellington region.
