Sea-Water Intake, Outfall & Reservoir System
A neutral reference architecture for coastal aquaculture water infrastructure — intake heads, pump stations, transmission mains, storage / settlement reservoirs and marine outfalls. Applies to shrimp farms, marine RAS, hatcheries and integrated processing sites. Buyer-side engineering only.
Project assumptions
Score your project in 60 seconds
Set your current status on seven factors. We calculate a 0–100 readiness score, flag gaps EPCs and lenders will raise, and pre-fill an RFQ your concierge can act on immediately.
Planning — foundational work still open, but structured RFQs feasible
- Energy plan: Grid connection secured
- CAPEX clarity: USD 2M–10M — mid commercial
- Sign a site option or lease for at least 20 years
- Commission water lab tests (salinity, TAN, iron, TDS) and file abstraction permit
- Engage local permitting consultant and file EIA scoping
- Secure at least one signed LOI from a processor or importer
Indicative execution readiness. Not a credit decision or engineering warranty.
System stack
Intake head & screening
- • Passive wedge-wire T-screens or velocity-cap intake heads
- • Coarse bar screens + drum screens on shore
- • Anti-fouling: hypochlorite dosing or copper-alloy screens
- • Fish-friendly through-slot velocity < 0.15 m/s
Pump station
- • Vertical turbine or submersible split-case pumps, N+1
- • VFD-driven with soft start and pressure control
- • Duty rotation and surge protection (air valves, surge tanks)
- • Chemical dosing skid (hypochlorite, anti-scalant)
Transmission & filtration
- • HDPE or GRP transmission mains sized for < 2 m/s velocity
- • Sand filters or disc filters at reservoir inlet
- • Cartridge polish + UV for hatchery-grade water
- • Isolation valves + air release + drain points
Storage & settlement reservoir
- • HDPE-lined earthen reservoir sized for 12–48 h autonomy
- • Baffled inlet + settlement zone before production draw
- • Level, DO, temperature, salinity, turbidity monitoring
- • Emergency spillway + reservoir isolation valve
Marine outfall
- • HDPE outfall pipe with weighted concrete ballast
- • Diffuser section for rapid dilution (permit-driven)
- • Bathymetric survey + hydrodynamic mixing zone model
- • Permit-grade discharge sampling manhole
SCADA & compliance
- • Flow, pressure and quality telemetry from intake to reservoir
- • Cathodic protection monitoring on submerged steel
- • Annual dive inspection + biofouling report
- • Environmental compliance dashboard for regulator
Project stages
- 1. Site & bathymetric surveyIntake / outfall siting, currents, wave climate, seasonal salinity, sediment. 6–10 weeks.
- 2. Hydraulic & CFD conceptPump / pipeline sizing, transient analysis, outfall mixing-zone modeling. 8–12 weeks.
- 3. Environmental & marine permitsEIA, coastal-zone permit, discharge permit, navigation clearance. 12–24 weeks.
- 4. Neutral RFQProject-matched marine contractors, pump vendors, HDPE suppliers, SCADA. 8–12 weeks.
- 5. Marine constructionPipe fusion, floating installation, ballasting, dive works, screen install. 4–8 months.
- 6. Onshore constructionPump house, reservoir, filtration, SCADA, cathodic protection. 6–10 months.
- 7. Commissioning & permit sign-offHydrostatic tests, capacity trials, discharge compliance run. 2–4 months.
Main CAPEX drivers
Indicative share of total installed cost. Actual split varies by region, redundancy, automation and civil scope.
| Marine intake / outfall pipelines + installation | 25–35% |
| Pump station (pumps, VFDs, switchgear) | 15–22% |
| Reservoir civil works + liner | 12–18% |
| Screening & filtration equipment | 8–12% |
| Environmental permits & marine surveys | 4–8% |
| SCADA, telemetry & cathodic protection | 4–7% |
| Engineering & marine works project management | 8–12% |
| Contingency (marine works) | 12–18% |
Bankability questions
- Are marine permits (coastal zone, EIA, discharge) achievable in the target timeline?
- Is bathymetric + current data current (< 24 months) and site-specific?
- Is the outfall mixing-zone model accepted by the regulator?
- Is pump redundancy (N+1) matched to the biological criticality of the load?
- Is the reservoir volume matched to the longest expected intake shutdown?
- Is a qualified marine EPC contractor identified for the offshore scope?
- Are biofouling / storm damage O&M costs modeled over 20 years?
- Is CAPEX supported by class-3 estimates from ≥2 independent RFQ respondents?
Key project risks
- Marine permit delays — start EIA in parallel with concept design.
- Intake biofouling reduces flow — dosing + inspection discipline critical.
- Storm damage to intake head — design to 1-in-100-year wave / current.
- Outfall dilution failure triggers permit exceedance — CFD model validation is not optional.
