Plumbing, Piping, and Distribution Network Installation
By Bestcare Borehole Drilling
A borehole or storage tank is only useful if water actually reaches the taps, fixtures, and outlets where it’s needed. That’s the job of a properly designed water distribution network, and it’s a stage that gets rushed far too often, leading to pressure problems, leaks, and pipes that need replacing within a few years. Bestcare Borehole Drilling handles plumbing and piping installation as a full engineering task, not an afterthought tacked onto the drilling contract.
Whether it’s a single household system or a multi-building distribution network across a commercial property, the goal is the same: reliable pressure, minimal loss, and a layout that won’t need constant repair.
Processes Involved in Plumbing and Distribution Network Installation
| # | Process | What It Involves |
|---|---|---|
| 1 | Water Demand & Layout Assessment | Mapping outlets, usage points, and required flow rates |
| 2 | Pipe Sizing & Route Planning | Selecting pipe diameters and routing to minimize pressure loss |
| 3 | Trenching & Groundwork | Excavation for underground pipe runs |
| 4 | Pipe Laying & Jointing | Installing and connecting pipe sections |
| 5 | Pressure & Booster System Integration | Adding pumps or pressure tanks where needed |
| 6 | Testing, Backfilling & Commissioning | Pressure testing, leak checks, and final handover |
1. Water Demand & Layout Assessment
We start by mapping every point that needs water, from kitchen and bathroom fixtures to outdoor taps, irrigation points, and any commercial equipment. This determines the minimum flow rate and pressure requirements the network needs to deliver simultaneously at peak use.
2. Pipe Sizing & Route Planning
Undersized pipes cause pressure drops at the far end of a network; oversized pipes waste money unnecessarily. We calculate appropriate diameters for main lines and branch lines based on distance, elevation changes, and simultaneous demand, then plan the most direct and least disruptive routing across the property.
3. Trenching & Groundwork
Underground pipe runs need trenches dug to appropriate depth for frost and mechanical protection, even though frost isn’t a major concern locally, depth still matters for protecting pipes from surface loading and root intrusion. We coordinate trenching to avoid existing structures, drainage, and other utility lines.
4. Pipe Laying & Jointing
We work with uPVC, HDPE, and galvanized steel piping depending on the application and pressure requirements. Joints are solvent-welded, threaded, or compression-fitted according to material type, with attention paid to expansion allowances on longer runs to prevent joint failure over time.
5. Pressure & Booster System Integration
Where gravity feed or standard mains pressure isn’t sufficient, particularly for multi-storey buildings or extended networks, we integrate booster pumps and pressure tanks to maintain consistent flow at every outlet, including the furthest and highest points on the property.
6. Testing, Backfilling & Commissioning
Before any trench is backfilled, the full network is pressure tested to identify leaks or weak joints while repairs are still easy to make. Once testing confirms a sealed system, trenches are backfilled and compacted, and the client is walked through shut-off valve locations and basic system operation.
Estimated Cost of Plumbing and Distribution Network Installation
| Service | Estimated Cost (KES) |
|---|---|
| Demand assessment & layout design | 5,000 – 12,000 |
| Piping (per metre, uPVC standard) | 300 – 800 |
| Piping (per metre, HDPE for underground mains) | 500 – 1,200 |
| Trenching (per metre) | 200 – 500 |
| Booster pump installation | 25,000 – 70,000 |
| Full residential distribution network | 80,000 – 250,000 |
| Commercial/multi-building network | 300,000 – 1,000,000+ |
Final pricing depends on property size, pipe material, terrain, and number of outlets.
Frequently Asked Questions
1. What pipe material is best for underground water lines? HDPE is generally preferred for underground mains due to its flexibility and resistance to ground movement, while uPVC is common for above-ground and internal plumbing.
2. How deep should underground pipes be laid? Typically 45–60cm below ground for standard residential lines, deeper under driveways or areas with vehicle loading.
3. Can an existing plumbing network be upgraded without full replacement? Often yes, particularly for pressure issues, which can sometimes be resolved by adding a booster pump rather than replacing the entire pipe network.
4. How long does a full residential installation take? A standard residential network typically takes 3–7 days depending on property size and number of outlets.
5. Do you handle both new installations and repairs to existing networks? Yes, we handle new distribution network design and installation as well as leak detection, repairs, and upgrades to existing systems.
5 Reasons to Choose Bestcare Borehole Drilling
- Engineering-first approach — pipe sizing and routing are calculated, not estimated by eye.
- Quality materials — we use durable, pressure-rated piping suited to long-term underground and above-ground use.
- Full-system thinking — plumbing design accounts for the borehole or storage source it connects to, avoiding mismatched pressure or flow.
- Pressure testing before backfill — leaks are caught and fixed while trenches are still open, not after.
- Single contractor accountability — from source to tap, one team manages the entire water delivery chain.
