Three options. Only one actually works for your business.
Three customer types, a rebate window that shifts, and the kit-supply-only mob who win on price
Water tank installation in Australia has three barely-overlapping customer pipelines and a regulatory layer that changes constantly. Pipeline one: residential rainwater tank for the existing home, often driven by a council rebate (Sydney Water, SA Water, Yarra Valley Water) or a personal sustainability goal, with the in-ground slimline vs above-ground decision deciding the install scope. Pipeline two: new builds in NSW where BASIX water-efficiency rules require a tank above a certain dwelling size, with the builder controlling the spec and the timing. Pipeline three: farm, acreage and rural property stock-water tanks, where the install is bigger (30,000L plus), the customer is more technical, and the install often includes mains-pressure pumps and full plumb-in. Each is a different customer, a different keyword, a different sales conversation. Most water-tank installer sites have one generic 'water tanks' page that ranks for none of them. The kit-supply-only mob (Bunnings, online suppliers, Bushmans, Polymaster direct) sit at the top of every 'rainwater tank' search and undercut you on price because they don't install. You're not selling a tank; you're selling the concrete pad, the first-flush diverter, the leaf-eater inlet, the council BCA-compliant install, and the connection to garden irrigation and house mains backup. The marketing has to make that distinction loudly or you lose the quote.
Good water tank installer marketing is three hubs kept separate plus a rebate-window content cycle plus an install-vs-kit-supply positioning spine. Hub one: residential rainwater tank with brand sections for Bushmans, Polymaster, Kingspan Rainwater Harvesting and the local poly-tank brands, with the above-ground vs in-ground slimline decision tree as the conversion mechanic, capacity sizing guidance (5,000L, 10,000L, 22,000L), and per-suburb pages so 'rainwater tank install [suburb]' ranks. Hub two: BASIX new-build B2B for NSW builders, with the BASIX water requirement explained simply, the typical builder-spec tank sizes, and an enquiry path aimed at site managers and project builders. Hub three: farm, acreage and rural stock-water tanks with 30,000L+ capacity options, mains-pressure pump install, full plumb-in, and the regional postcodes you actually travel to. Plus a greywater-diversion sidebar for the sustainability-driven customer. The rebate-window content cycle runs every quarter: when a Sydney Water or SA Water rebate opens, the Content Agent ships an explainer page within 48 hours and the Advertising Agent runs a rebate-window ad set. The install-vs-kit-supply spine: a 'why you don't want to install a tank yourself' page, council BCA compliance and inspection schedule called out, garden-irrigation and house-mains-backup plumb-in detail on every page.
Six agents, working in your accounts.
Account Lead, Web, SEO, Advertising, Social Media, and Content. One platform, one bill, you approve the work.
Builds your annual plan around the three pipelines and the rebate-window cycle: residential slimline installs running year-round with rebate-window spikes, BASIX new-build B2B work where the spec is set by the builder and timing is fixed, farm and acreage stock-water installs running heavier in dry months. Briefs the other agents so the suburb pages, the rebate-window ads, the install-detail social posts and the builder outreach all push at the customer you actually want, not a generic 'water tank' page that loses to the kit-supply-only mob.
Imports your existing site so you stop paying for hosting plus a CMS subscription, and ships three hubs (residential rainwater, BASIX new-build B2B, farm stock-water) plus a greywater diversion sidebar instead of one generic page. Suburb pages per area, brand sections for Bushmans, Polymaster and Kingspan Rainwater Harvesting, above-ground vs in-ground slimline decision tree as the conversion mechanic, and a 'why you don't want to install a tank yourself' page that distinguishes you from the kit-supply-only mob. Two taps to push live.
Goes through your live site for what actually moves water-tank rankings: '[tank type] install [suburb]' H1s, brand-specific keyword targeting ('Bushmans installer [suburb]', 'Polymaster slimline [suburb]') because customers really do search by brand, water-tank-cleaning-service schema (not generic plumber), internal links from suburb pages into the rebate-window explainer so the urgency-driven customer benefits from cross-page authority, and a Google Business Profile listing every brand and install type. Auto-applies the low-risk fixes.
Runs three parallel Google Ads campaigns. Campaign one is residential rainwater on '[suburb] rainwater tank installer' with a sharp ramp every time a Sydney Water, SA Water or Yarra Valley Water rebate window opens. Campaign two is BASIX new-build B2B targeting NSW builders and project home companies on 'BASIX water requirement installer' and 'rainwater tank for new build NSW'. Campaign three is farm stock-water targeting rural and acreage postcodes on '30,000L water tank installer' and 'farm water tank install'. Meta runs the install-detail video posts to catch the sustainability-driven customer.
Turns every install into a post in your real accounts: a 10,000L Bushmans slimline in Roseville with the concrete pad pour, a 22,000L underground tank dug into a Bowral acreage, a greywater diversion system retrofit in Marrickville, a 50,000L Kingspan corrugated steel on a Hunter Valley winery. Builds the install-detail trust signal (first-flush diverter, leaf-eater inlet, BCA-compliant overflow, house-mains backup tee) that wins the customer who'd otherwise pick the kit-supply-only mob on price. You upload one photo per job, the agent drafts the caption in your voice, you approve.
Drafts the long-form pieces customers Google before they ring: 'how to claim the Sydney Water rainwater tank rebate', 'BASIX water requirement for new builds NSW explained', '5,000L vs 10,000L rainwater tank: what size for a 3-bedroom home', 'in-ground vs above-ground slimline tank: which is right for your block', 'farm stock-water tank sizing for 50 head of cattle'. Two drafts a month, in your voice, that pull the considered researcher to your site before the kit-supply-only ad lands first.

Water tank installation has three customer pipelines that share almost no marketing in common, a rebate-window cycle that the customer never tracks themselves, and a kit-supply-only competitor that wins on tank price but skips concrete pads, first-flush diverters and council BCA-compliant installs. The installers who win the next three years are the ones with separate hubs per pipeline, a rebate-window content cycle that ships within 48 hours of a program opening, and a 'why you don't want to install yourself' positioning spine that calls out everything the kit-supply mob skip.
Agencies are too dear to ship three hubs and run rebate-window ad cycles for $3.5k a month. Tools are cheap but the BASIX builder outreach never happens and the farm stock-water page never gets written. In-House is the third option: for $299 a month the agents ship the hubs, time the ads to the rebate windows, post every install detail, and pitch the BASIX builders you want as referral partners. You stay in the driver's seat, two taps to approve, minutes a day. Stop losing the next 10,000L install to the Bunnings mob because the customer didn't know what was missing.
