# What a Full Turnkey Water Project Actually Involves, From First Call to Handover

"Turnkey" is one of the most frequently used and least precisely defined terms in the water infrastructure market. Suppliers use it to mean everything from a simple pump installation with minimal documentation to a complete, multi-component water independence project covering source development, treatment, storage, solar integration, monitoring, and compliance certification.

For a Johannesburg facility manager scoping a water independence project for the first time, the gap between what "turnkey" promises and what individual suppliers actually deliver is significant. It can create budget, timeline, and compliance surprises that derail projects that were otherwise well-intentioned.

This guide explains what a genuine turnkey water infrastructure project involves, stage by stage, so facility managers know what to expect, what to plan for, and what questions to ask any supplier before committing to a proposal.

## Stage 1: Site Assessment and Demand Analysis

Every credible turnkey water project begins with a site assessment. This is not a sales visit; it is an engineering evaluation that determines what infrastructure the site actually needs and whether the proposed solutions are viable at the specific location.

A complete site assessment for a Johannesburg facility maps current supply connections, storage, treatment, and distribution systems. It establishes actual daily water consumption by category and time of day, evaluates supply reliability and quality, assesses groundwater viability where borehole development is considered, and identifies access, space, underground-service, heritage, and infrastructure-placement constraints.

The outcome is a clear specification brief: the documented basis on which the project is designed. A proposal prepared without a site assessment is a guess, not an engineering specification.

## Stage 2: Project Design and Specification

Based on the site assessment, iWater Management's engineering team designs the project, selecting and sizing each component to meet the facility's specific requirements.

A full design covers the borehole depth, casing, and yield target where groundwater development is included; a treatment system matched to source-water test results and each application's quality requirements; modular steel tank capacity based on the demand profile and required reserve period; solar array, battery, and pump-drive sizing; monitoring sensor positions and alert thresholds; and integration with the facility's existing distribution network.

The design is documented in a project specification that provides the basis for the installation programme and the documentation package supplied at handover.

## Stage 3: Permitting and Compliance Preparation

Before physical installation starts, the project team identifies the permits and approvals applicable to the proposed water use and infrastructure. For projects that include groundwater extraction, requirements can vary according to abstraction volume, location, and the applicable authorisation framework.

Permit-processing timelines differ by project and region. They should be accounted for during planning, with installation preparation coordinated carefully so that the programme remains realistic and no regulated activity begins prematurely.

## Stage 4: Installation and Construction

Physical installation follows the approved design. For a complete turnkey project, the scope may include drilling to the specified depth, casing and sanitary-seal installation, extended yield testing, laboratory analysis of raw-water quality, and installation and commissioning of the selected treatment system.

The construction programme can also include concrete-base preparation and modular steel tank assembly, installation of the solar array, battery, inverter, and pump drive, monitoring sensor and platform setup, alert testing, and final connection of the new infrastructure to the facility's distribution network.

Each stage is documented through photographs, specifications, and completion records that become part of the final handover package.

## Stage 5: Commissioning and Compliance Certification

Commissioning is the point at which all installed components are tested as an integrated system: pump performance against the available power supply, treatment performance against source-water quality, storage against the facility's distribution demand, and monitoring against the agreed alert parameters.

Commissioning includes SANS 241 testing of treated-water output where potable water is required, confirming that the system produces water that meets the applicable standard before entering service. Testing is conducted through iWater Management's SANAS-accredited laboratory partnerships.

For a complete solar-powered water system (https://iwatermanage.co.za/services/solar-powered-systems), commissioning also tests resilience during a simulated grid interruption and confirms that the required flow rate and pressure are maintained.

## Stage 6: Handover and Ongoing Support

Project handover brings the full technical record together. Depending on scope, this includes borehole drilling (https://iwatermanage.co.za/services/borehole-drilling) logs, casing specifications, yield-test reports, source- and treated-water test results, treatment-system specifications, service manuals, warranties, tank installation records, solar performance and commissioning records, and monitoring-system settings.

The handover should also give the facility team a clear operating and maintenance schedule. iWater Management provides ongoing support through custom maintenance plans (https://iwatermanage.co.za/services/monitoring-compliance) and water monitoring and compliance services, helping the system continue to perform to specification and keeping its records current.

The Department of Water and Sanitation (https://www.dws.gov.za/) provides guidance on Water Use Licence requirements and South Africa's water-use regulatory framework.

The South African Bureau of Standards (https://www.sabs.co.za/) maintains standards applicable to water infrastructure, including SANS 241 and related component standards.

## Frequently Asked Questions

## How long does a full turnkey water project take from first call to handover?

Timing depends on scope. A borehole, treatment, storage, and solar project for a Johannesburg commercial facility typically takes eight to fourteen weeks from site assessment to commissioning and handover, depending on geology, approval timelines, and equipment lead times. iWater Management provides a project programme at proposal stage.

## Can I phase a turnkey water project across multiple budget cycles?

Yes. iWater Management designs projects with phasing in mind where budget constraints require it. A typical sequence begins with storage to reduce supply-disruption risk, followed by borehole development and treatment, with solar integration as a third phase. Each phase delivers standalone value while contributing to the complete system.

## What happens if the borehole yield is lower than expected?

Yield expectations are established through a hydrogeological assessment before drilling. If actual yield is lower than expected, the options may include drilling deeper, evaluating another drilling position, or revising the system design to operate within the confirmed sustainable yield.

## What should a facility manager know about water-use authorisation?

Requirements depend on the source, abstraction volume, location, and intended use. Facility managers should confirm the applicable process and allow sufficient time in the project programme before regulated water use begins. The Department of Water and Sanitation is the authoritative source for current requirements.

## What ongoing obligations does a facility have after the project is complete?

Ongoing needs can include scheduled water-quality testing, maintenance of the treatment system and associated infrastructure, monitoring of extraction volumes, and retention of operating records. The exact schedule depends on the system, its use, and any applicable authorisation conditions.
