Investor presentation · October 2026

Water security that pays for itself.

R3.0 million of equity for 20% and a R5.0 million expansion facility to roll out fully managed borehole water for businesses, estates and institutions, starting in Johannesburg.

01 · The problem

Johannesburg’s water network is failing

Businesses in Johannesburg pay some of the highest water prices in the country for a supply that is less and less reliable.

Lost or unbilled
47%

of the water Johannesburg buys is lost or never billed (47.3% in DWS’s 2025 No Drop assessment; 47.1% in 2025/26, unaudited).

Pipe leaks
50,536

recorded between June 2025 and June 2026: about 140 a day.

Outages
40%

of Johannesburg households had water outages of two days or more in 2025. Cape Town: 8%.

Backlog
R26.6bn

infrastructure backlog. Only 17 km of the 12,364 km network was replaced in 2023/24.

Storage

About 28 hours of average consumption in reservoirs (2022), against a 48-hour benchmark.

Finances

On 30 June 2026 the City swept R3.4bn out of Johannesburg Water, leaving R1.8bn of creditors unpaid.

Rand Water
77%

of Rand Water’s ~5,000 Ml/day goes to Johannesburg, Tshwane and Ekurhuleni. Johannesburg draws about 1,720 Ml/day, 190 Ml/day above its bulk allocation (Feb 2026).

New supply
2029

Lesotho Highlands Phase II tunnel commissioning target, about nine years late; cost now R53bn. DWS told Parliament it will not remove the need to cut Gauteng’s demand.

National picture
47.3%

national non-revenue water (DWS 2025 assessment), up from 37% in 2014. 47% of 848 wastewater systems are critical (Green Drop 2025); the Minister puts the repair bill at R400bn.

Price

Business water in Johannesburg: R136 a kilolitre

Commercial water above 200 kL a month plus sanitation, excl. VAT. Hover a bar for the split.

Sources: City of Johannesburg approved tariff schedules 2017/18 to 2026/27.

Since 2017/18
×2.2

9.3% a year compound. In 2026/27 business water rose 8% and sanitation 11%.

Faster than inflation
10.3% a year

Stats SA water prices, July 2017 to July 2022, against 3.9% CPI (K Walsh, SARB economic note, 2023).

Bulk cost
+11%

Rand Water’s 2026/27 bulk increase, after about 15% in 2025/26 (CoJ budget; Business Day, 27 May 2026).

Cape Town

Cape Town’s risk is scarcity, not breakdown

74%

dam storage in mid-October 2026; 75.8% in September, against 92% a year earlier.

+50%

rebound in daily demand since the 2017 Level 5 restrictions: about 570 to 850 Ml/day.

2036

the earliest the City’s New Water Programme will be fully operating; desalination pushed back about five years.

Per kL, 2026/27, excl. VAT Johannesburg Cape Town
Commercial water R73.72–R77.77 R39.56
Commercial sanitation R58.66 (on 100%) R29.57 (on 95%)
Combined R132–R136 about R68

Business water in Cape Town costs about half what it does in Johannesburg, so Cape Town is a later, scarcity-led market. Households there pay R95.63/kL above 35 kL a month (2026/27, excl. VAT); a SARB economic note found Cape Town’s 20 kL price rose 18.9% a year above inflation, 2016–2021, the steepest of the metros. Registered boreholes and wellpoints rose from about 1,500 (2016) to about 26,000 (2019) through the drought.

02 · The solution

We replace the municipality as a site’s primary water supply. The customer pays half of what our water saves them, with no capital outlay.

WaterGrid funds, drills, purifies, monitors and maintains a private borehole supply on the customer’s property and keeps the municipal connection as backup. The customer pays one monthly fee for the life of the contract.

How it works

One fee covers everything from aquifer to tap

Pricing

Customers pay half of what our water saves them

Monthly fee = 50% of the trailing 12-month municipal charges our supply removes: water charges on every kilolitre we supply, and sanitation only on water that never reaches the sewer. Sewer-bound borehole water must be metered and registered for sanitation (by-laws s 72(5)), which the City bills per kL. R10,000 minimum; escalates with the City’s water tariff; five- to ten-year term.

What would your business save?
Irrigation and evaporative cooling avoid the sewer; toilets, kitchens and process water do not.

Per month, excl. VAT; fixed levies continue and are excluded. Before counting the cost of outages, tankers and storage the customer no longer needs.

Who we serve

Three kinds of site that cannot run dry

Payback from commissioning for each 1,500 kL a month reference profile, at the model’s current assumptions.

Why now

Water is following the path electricity took

When the utility failed, private supply scaled on long contracts. We lock in five- to ten-year terms while the need is acute.

2.3→7.4 GW

rooftop solar, Oct 2022 to Oct 2025 (Eskom estimate).

18 GW

private generation registered with NERSA since 2018, about R361bn.

03 · Unit economics

Three things decide a site’s economics

Where the water goes

per kL displaced. Water that never reaches the sewer (irrigation, evaporative cooling) removes water and sanitation charges. Sewer-bound water removes only the water charge.

Water quality
UF vs RO

Good granite water needs filtration, ultrafiltration and UV. Saline or polluted water needs reverse osmosis, which roughly doubles treatment cost; RO sites are priced separately.

Scale and yield

from one well-sited borehole. Siting, licensing, drilling, controls and telemetry are largely fixed, so small sites take much longer to pay back.

Reference site: what it costs to build

Reference site: a month in year one

Cumulative site cash after capex, from commissioning

Larger sites pay back faster

Payback by monthly volume, mixed site

Where the 12–15 month payback holds

Payback (months) by capex and share avoiding the sewer

Blue: 15 months or less. Grey: 15–18. Orange: longer. Volume as set in the model; fee escalation and running costs as for the reference site.

Contract architecture

The contract protects the capital until it is repaid

Term Five years from commissioning; ten targeted. CPA s 14 does not apply between juristic persons (s 14(1)).
Fee 50% of the trailing 12-month municipal charges our supply removes; R10,000 minimum.
Escalation Annually, in step with the City’s approved commercial water tariff increase.
Take-or-pay From commissioning, after the licence and City consent, whatever the volume drawn; municipal backup stays.
Ownership WaterGrid owns pumps, storage, plant and telemetry (WSA s 79); borehole works accede to the land.
Early exit Unamortised capital plus a break fee, or transfer of the system at that price.
Service levels SANS 241 quality for drinking water, availability and response times; fee credits if missed.
Security Debit order; deposit or guarantee for weaker credits; receivables cedable to the lender.

Commercial terms as proposed by WaterGrid; subject to final contract drafting.

04 · Investor model

Change the assumptions. Watch the returns move.

Every number on this page runs on one model. Move a slider, pick a scenario, or set the exit multiple; the unit economics above and the projection, cover ratios and returns below all recompute.

Live sites, month by month
Value of the investor’s stake

Cash and facility balance
Five-year projection

Calendar years from January 2027; excl. VAT; rounded. Tax at 27% with assessed losses (R1m or 80% rule) and SARS IN 47 wear and tear; none on borehole works. No cover ratio while EBITDA is negative.

Strategy 1 and Strategy 2 at these assumptions

Strategy 1 uses the equity alone; Strategy 2 adds the facility. Site cash is reinvested; no further equity. Signings are limited by sales capacity and by keeping at least R250,000 of cash through each site’s build.

Illustrative model, not an offer or a forecast of certain outcome. Payback is measured from commissioning. Facility terms are WaterGrid’s proposal, not a lender’s offer; prime 10.75% as at 25 September 2026.

06 · Regulation

A regulated path, handled for the customer

Johannesburg’s catchments allow little or no groundwater under the general authorisation, so every reference-size site needs a full water use licence. Tap a step.

Requirement Source How WaterGrid handles it

Sources: National Water Act; GenN 538 (2016); GN R267 (2017); CoJ Water Services By-Laws 2023; CoJ borehole process (2025); Water Services Act. Subject to legal review.

07 · Go-to-market

A free water assessment opens every sale

Roll-out

Johannesburg first, where the price gap is widest

Cumulative contracts signed under Strategy 2 at the model’s current assumptions, all priced on CoJ 2026/27 tariffs. No boreholes on dolomite (CoJ by-laws s 72(1)).

The raise

R3.0m of equity and a R5.0m facility

Equity

Facility: proposed terms

Equity carries each site to its licence; the lender funds only licensed, yield-tested sites with signed contracts. Terms are WaterGrid’s proposal and assumptions, not a lender’s offer.
