What Southern Water Engineering does

Southern Water Engineering (SWE) is a privately held, 100% New Zealand-owned water engineering consultancy and systems integrator headquartered in Marlborough, founded by Stephen Leitch in 2010 and operating since 2011. The company designs, supplies, installs and services irrigation, fertigation, stockwater, effluent and wastewater systems — plus electrical, SCADA/HMI and telemetry automation — primarily for viticulture, with adjacent work in civic water engineering, mixed farming and sports turf. SWE has built a family of registered proprietary products (SmartFertigation, SmartSpray, SmartControl/SmartFlow dripline, SmartPump) and recurring services (SmartAudit, SmartWatch effluent monitoring, SmartMaintenance managed services, SmartConsult 'thinktank' consulting), supported by a swelink telemetry platform in beta.

SWE operates a sales-led, enterprise-field-sales go-to-market targeting New Zealand's major wine producers (Pernod Ricard NZ, Treasury Wine Estates/Matua Wines, Rapaura Springs, Drylands Winery) plus mid-market vineyards, and earns revenue across four streams: engineering design and consulting, system installation and construction, maintenance and managed services, and monitoring/auditing. Pricing is project-specific and quote-based. SWE has approximately 16 full-time employees expanding to 25+ during the October–April grape-growing season, and manages 28,000+ hectares of vines in Marlborough — over 70% of New Zealand's total vineyard area — with the company exporting SmartFertigation systems to the USA and Australia. SWE holds Toitū carboNZero certification, IrrigationNZ Blue Tick accreditation, SiteWise Green status, and ACC WSMP, and is a regional award winner (Supreme Award 2013, Cawthron Environment Award 2017, NZ Hi Tech Awards 2024 finalist).
