Water supply and drainage answer different operating needs. Supply pipework must deliver the required flow and pressure, while wastewater and stormwater depend heavily on pipe levels, falls, venting and suitable discharge routes.
Where facilities have storage tanks, booster pumps or multi-level drainage, BILOCO reviews equipment access, connection locations and practical pipe routing before works begin.
Water supply and distribution
Water supply networks should be routed logically from the source or storage tank to the point of use. Where booster pumps are included, flow, operating pressure, suction conditions and controls need appropriate review.
Isolation valves, meters, strainers and drain points must remain accessible. A neat-looking installation can still be difficult to maintain if a single repair requires shutting down an entire area.
Wastewater and rainwater drainage
Gravity drainage is highly sensitive to levels and falls. Incorrect pipe elevations or missing cleanouts can create standing water and make blockages difficult to remove. Routes should be checked against slabs, beams and shafts.
Rainwater drainage needs suitably located outlets, design flow capacity, vertical connections and approved discharge points. Stormwater and wastewater systems must not be combined unless the design and local requirements permit it.
Pipework coordination on site
Ceiling voids, plant rooms and service shafts can be crowded. Pipe routes must be coordinated with electrical services, rotating equipment, hot pipes and building structure, while preserving space to remove valves and pumps.
Supports, penetrations and direction changes require suitable details for the selected pipe materials and the building’s waterproofing and fire-stopping requirements. Site changes belong in updated drawings.
Pressure testing, leakage checks and pump operation
Pressure testing should follow the design and the selected pipe material before concealed work is closed. Drainage systems require watertightness and flow checks, especially at hidden joints. Test conditions and results should be recorded.
Pump commissioning is more than confirming that a motor starts. Rotation, pressure, unusual noise, valve positions, control signals and maintenance access all warrant attention.
Information needed for a water-services proposal
Useful inputs include plumbing layouts, fixture and outlet schedules, tank and pump schematics, drainage levels, existing connections and available water quality data.
Where treatment plants are involved, mechanical/electrical installation should be distinguished from process treatment design and discharge performance commitments. These require their own verified scope and specifications.
Inputs needed for plumbing and drainage pricing
Send plumbing layouts with levels, discharge destinations, tank positions and pump information. For process-water or wastewater-treatment facilities, distinguish mechanical pipe installation from the treatment technology itself.
- Peak flow demand, required service pressure and outlet quantities.
- Pipe materials and any insulation or corrosion-resistance requirements.
- Connection elevations, existing chambers and excavation constraints.
Clear boundaries help separate the pipework, pumps and treatment equipment in the estimate.
