The "Surface vs Submersible" Decision in 30 Seconds
If the water is within 25 ft of where you can place the pump, surface self-priming is faster to deploy, easier to service, and cheaper to operate. If the water is deeper than 25 ft below grade, in a confined space, or in a permanently submerged condition, you need a submersible. For mine pits and deep excavations, hydraulic submersibles (Heidra) move dramatically more water than electric for the same physical footprint — but require a hydraulic power unit on the surface.
Surface Self-Priming · The Industry Standard
Godwin Surface Pumps — CD · HL · NC · Wet-Prime
Godwin invented the modern auto-prime self-priming dewatering pump. The CD, HL, and NC series are the backbone of construction dewatering, sewer bypass, and emergency response across North America. Trailer-mounted, diesel-driven, designed to run unattended for days.
CD Series — High-Volume Trash Pumps · 4" through 12"
The workhorse of the Godwin lineup and the most widely deployed dewatering pump series in North America. Up to 18,500 GPM at lower heads, with solids handling up to 3" through the open-impeller trash design. Available in 4", 6", 8", and 12" discharge sizes, with diesel-driven trailer-mount, skid-mount, or electric drive options.
Flow: up to 18,500 GPMHead: up to 260 ftSolids: up to 3"Drive: Diesel · ElectricSizes: 4", 6", 8", 12"
Why CD Series Owns Construction Dewatering
The CD's reputation comes from three things: (1) the venturi-based PrimeGuard auto-prime system handles air-water mixtures without losing prime; (2) the open semi-open impeller passes solids that clog conventional centrifugal pumps; (3) the diesel drive runs unattended overnight on a single fuel fill. For active construction sites where the pump must run reliably without supervision, nothing else has the same track record.

HL Series — Medium-Volume High-Head · 270–540 ft TDH
When the application demands high head pressure rather than maximum flow — long discharge runs, jetting operations, pressure boosting, deep-lift dewatering — the HL series delivers. Single-stage open impeller still passes solids without clogging. Up to 5,300 GPM at 270–540 ft TDH. Auto-prime system identical to CD series. Best fit for sewer force-main bypass, agricultural irrigation duty, and oilfield well pad dewatering where the discharge run is long.
Flow: up to 5,300 GPMHead: 270–540 ft TDHSolids: up to 2"Drive: Diesel · ElectricBest for: Long discharge · jetting · high lift
NC Series — Strictly Vertical Self-Cleaning Impeller
The NC (Non-Clog) series uses a strictly vertical self-cleaning impeller with hydrostatic startup — the impeller geometry continuously wipes itself, so even rag-laden municipal sewage doesn't clog the pump under sustained operation. Up to 4,000 GPM with 105–300 ft head, solids passing the full impeller eye. The right choice for sewer bypass on aging municipal systems where ragging is the dominant failure mode for conventional pumps.

Wet-Prime Series — Engine-Driven Portable
Engine-driven wet-prime portable pumps in 4 model variants (GWP, GWPS, GWP-N, etc.). For applications where the pump can stay primed via flooded suction — construction site sumps, irrigation, agriculture, manhole drainage, jetting. More compact and lower-cost than auto-prime CD series; trade-off is requires manual priming if it loses water. 30–540 GPM range, 2"–4" discharge, gasoline or diesel engine options.

Submersible Dewatering · No 25-Foot Limit
Godwin Submersibles — Heidra · Sub-Prime · DBS
When the water is deeper than 25 ft below grade, in a permanently flooded condition, or in a confined space where surface equipment can't fit, submersibles are the only option. Three families cover three different operational profiles.
Heidra Hydraulic Submersibles — Mine Dewatering & Deep Pits
The flagship Godwin deep dewatering line. 17 models from 4" through 12" discharge, including dedicated high-head variants. Hydraulic-driven from a surface-mounted diesel power unit (HPU) — the pump itself contains no electrical components, making it intrinsically safe for explosive atmospheres common in mining and oilfield service. Up to 6,000 GPM at 765 ft head on the largest configurations.
Flow: up to 6,000 GPMHead: up to 765 ftSolids: up to 6"Drive: Hydraulic (diesel HPU surface)17 Models · 4"–12"
Why Hydraulic Drive vs Electric
Hydraulic-driven submersibles win in three specific scenarios: (1) deep pits where electric motor cable runs become impractical (voltage drop, conduit cost); (2) explosive atmospheres (mines, refineries, oilfield) where electric arc faults are unacceptable — Heidra has no electrical components below the surface HPU; (3) abrasive slurry service where motor heat dissipation is challenging. For typical construction dewatering, electric Sub-Prime is simpler and cheaper to operate.

DBS Diesel Backup System — 100% Pump Station Redundancy
Engineered diesel backup pumping system for municipal lift stations, water reclamation plants, sewer mains, and industrial process lines. Provides 100% pump-station backup — when grid power fails or primary pumps go offline, the DBS auto-starts and takes over the full station load. Diesel-driven (no grid dependency), up to 10,000 GPM at 600 ft head. PrimeGuard 3 microprocessor controller with FST remote monitoring for unattended operation.
Flow: up to 10,000 GPMHead: up to 600 ftSolids: 3"–4"Fuel: Diesel · Natural Gas · LPBackup: 100% station capacity
When DBS Pays for Itself
DBS pricing is significant — but a single 8-hour outage at a municipal lift station can cost more than the system in EPA fines, sewer overflow remediation, and emergency response. For lift stations serving population centers, healthcare, food processing, or any application where sewage backup creates immediate liability, DBS is an insurance product disguised as pumping equipment. Common applications: hurricane-prone municipalities, hospitals with on-site treatment, refineries with sewer-tied process water.
Engineered Dewatering Solutions
Specialty Pumps — Wellpoint & Rotary Lobe
Two specialty Godwin product lines that solve dewatering problems standard self-priming pumps can't address: vacuum-assisted water table control, and positive-displacement handling of slurry, sludge, and viscous fluids.
Wellpoint Pumps — Lower the Water Table
Wellpoint dewatering is the standard technique for lowering the water table around an excavation BEFORE digging — not pumping out water that's already in the hole. A series of small wellpoints (riser pipes with screened intakes) get jetted into the ground around the perimeter, connected to a vacuum-assisted header pipe, and pumped continuously to draw the water table down 10–20 feet across the entire site. Centrifugal pump with high-volume vacuum pump and air-water separator in a self-jetting wellpoint header system. Three models: CD125M, CD150M, CD225M.
Models: CD125M · CD150M · CD225MSystem: Vacuum + air-water separatorUse: Excavation water-table controlSelf-jetting risers
When Wellpoint Beats Direct Pumping
Wellpoint dewatering wins when: (1) the soil is sandy or saturated and direct excavation would collapse without water-table control; (2) the dig is below the existing water table by 5+ feet; (3) the project duration justifies the setup time (wellpoints take 1-3 days to install). Direct pumping (CD/HL series sumping the open excavation) wins for short-duration work, clay soils, and small footings. The right call is project-specific — Houston commercial deep-foundation work almost always uses wellpoint.
Rotary Lobe Pumps — Slurry, Sludge & Viscous Fluids
Positive-displacement rotary lobe pumps for applications where centrifugal pumps fail: slurry, sludge, viscous industrial fluids, low-abrasion service, wellpointing under heavy mud conditions, rock dewatering. Available in 6", 8", and 12" inlet, up to 3,175 GPM with 28" of suction lift capability and up to 638 cP viscosity handling. Trailer or skid-mounted, diesel-driven.
Flow: up to 3,175 GPMSuction Lift: up to 28"Viscosity: up to 638 cPSizes: 6", 8", 12"Drive: Diesel
Centrifugal vs Rotary Lobe — When to Switch
Centrifugal pumps (CD/HL/NC) lose efficiency rapidly when handling viscous fluids — water at 1 cP works perfectly, but mud at 100+ cP cuts flow dramatically and forces the impeller to over-spin. Rotary lobe is positive-displacement: each rotation moves a fixed volume regardless of viscosity. The trade-off is rotary lobe is more expensive, has more moving parts, and requires more maintenance. Switch to rotary lobe when viscosity exceeds ~50 cP or when handling sludge with significant solids loading.

Buy vs Rent Godwin Equipment
Most Godwin business runs through the rental channel — Xylem operates the largest dewatering pump rental fleet in North America. We compete by quoting purchase pricing for contractors and operators where ownership economics work better than rental. Run the numbers carefully.

- DrawbackCapital tied up; equipment depreciates
- Decision PointIf > 12 months continuous use → buy
The Math: When Buying Pencils Out
Industry rule of thumb: dewatering pump rental at 12-month continuous use typically equals 60-80% of equivalent purchase price. At 18-24 months continuous use, you've paid for the equipment outright but still own nothing. For municipalities, sewer bypass contractors, refinery turnaround operators, and any business with continuous predictable dewatering demand, ownership math wins. For one-off construction projects under 6 months, rental almost always beats buying. We'll quote either side honestly — call 281.664.8000.
Technical Reference
Dewatering Pump Sizing Quick Guide
Three numbers drive Godwin sizing: peak flow demand (GPM), Total Dynamic Head (TDH including discharge run + elevation), and solids handling requirement.
Step 1 — Estimate Required Flow (GPM)
| Application | Typical Flow | Recommended Series |
|---|---|---|
| Vault / manhole pump-down | 50–500 GPM | Mini Mac · Sub-Prime |
| Foundation excavation (small) | 500–1,500 GPM | CD80 / CD100 · Wet-Prime |
| Foundation excavation (large) | 1,500–5,000 GPM | CD150 / CD200 · CD300 |
| Sewer bypass (residential) | 500–2,000 GPM | NC150 · CD150 |
| Sewer bypass (municipal) | 2,000–8,000 GPM | NC200 / NC300 · DBS |
| Mine pit dewatering (small) | 500–3,000 GPM | Heidra 150 / 200 |
| Mine pit dewatering (large) | 3,000–10,000 GPM | Heidra 300 + HPU |
| Hurricane / flood emergency | 1,000–6,000 GPM | CD150 / CD200 / Wet-Prime fleet |
| Wellpoint dewatering | per system design | CD125M / CD150M / CD225M |
Step 2 — Calculate Total Dynamic Head (TDH)
TDH = Static Lift + Discharge Elevation + Friction Losses + Discharge Backpressure
Static lift = water surface to pump centerlineDischarge elevation = pump centerline to discharge pointFriction loss: 6" Sch 40: ~0.5 ft / 100 ft @ 1,000 GPM8" Sch 40: ~0.13 ft / 100 ft @ 1,000 GPMLong discharge runs → upsize pipe diameterIf TDH > 250 ft → choose HL series
Step 3 — Solids Handling & Service Conditions
Clear Water (no solids)
Foundation/excavation pumping where soil has settled, well-pointing return water, treated effluent. Standard centrifugal works.
→ Any CD / NC series
Sandy / Sediment-Laden
Most construction dewatering. Open semi-open impeller required to pass sand without impeller wear.
→ CD trash impeller
Rags / Municipal Sewage
Sewer bypass and aging municipal lines. Self-cleaning vertical impeller prevents ragging.
→ NC series only
Slurry / Sludge / High Solids
Mining slurry, lagoon dewatering, sludge transfer. Centrifugal won't work — need positive displacement.
→ Rotary lobe
Explosive Atmosphere
Mines, refineries, oilfield, chemical plants. Hydraulic-driven submersibles eliminate electric arc risk in pump.
→ Heidra hydraulic
Continuous Unattended Operation
Overnight, weekend, or remote operation requires PrimeGuard 3 controller + cellular monitoring + auto-fuel-fill.
→ Add PrimeGuard 3 + FST
Technical FAQ
Common Questions
What's the difference between a dewatering pump and a sump pump?
Sump pumps are residential equipment — handle clean groundwater, run on 120V household power, lift up to 25 ft, 30-70 GPM. Dewatering pumps are construction/industrial equipment — handle muddy water with sand and gravel, run on diesel or heavy 3Ø electric, move 500-18,500 GPM, lift water hundreds of feet, designed for unattended overnight operation. Different products for entirely different applications. A sump pump won't survive a single shift on a construction site.
Why is Godwin the industry standard for dewatering?
Three reasons: (1) The auto-prime PrimeGuard system actually works — competitors have come and gone but Godwin's vacuum-based prime maintains suction in air-water mixtures that defeat other designs. (2) Open semi-open impeller passes the sand and gravel that comes with construction dewatering without clogging or excessive wear. (3) The diesel drive runs unattended overnight on a single fuel fill — critical for jobs that can't have a watchman next to the pump. Three decades of construction dewatering have proven the design.
CD vs HL vs NC — which Godwin series do I need?
CD (Critically-Damped) is the standard high-volume trash pump for general construction dewatering — up to 18,500 GPM, up to 260 ft head, handles solids to 3". HL (High-Lift) is for high-head applications — long discharge runs, jetting, pressure boosting — up to 540 ft TDH. NC (Non-Clog) is for ragging conditions in municipal sewer bypass — strictly vertical self-cleaning impeller. Pick CD as the default; switch to HL when TDH > 250 ft; switch to NC for municipal sewage applications with rags.
When do I need a hydraulic submersible (Heidra) instead of electric?
Choose hydraulic when: (1) the pit is deeper than ~80 ft and electric motor cable runs become impractical due to voltage drop and conduit cost; (2) the atmosphere is potentially explosive (mining, refinery, oilfield, chemical plant) and electric arc faults are unacceptable — Heidra has zero electric components below the surface HPU; (3) abrasive slurry service where motor heat dissipation is challenging. For typical construction dewatering at depths of 25-80 ft, electric Sub-Prime is simpler and cheaper to operate.
What is wellpoint dewatering and when do I need it?
Wellpoint dewatering lowers the water table around an excavation BEFORE digging starts. A series of small wellpoints (1.5"-2" riser pipes with screened intakes at the bottom) get jetted into the ground around the excavation perimeter, connected to a vacuum-assisted header pipe, and pumped continuously to draw the water table down 10-20 feet across the entire site. Required when the dig is below the existing water table by 5+ feet AND the soil is sandy or saturated where direct excavation would collapse. Standard for Houston commercial deep-foundation work.
Should I buy or rent Godwin equipment?
Industry rule of thumb: rental at 12-month continuous use equals roughly 60-80% of purchase price. At 18-24 months continuous use, you've paid for the equipment but still own nothing. Buy if your dewatering demand is continuous and predictable for 12+ months — municipalities, sewer bypass contractors, refinery turnaround operators. Rent for one-off projects under 6 months. We quote either side honestly.
What's the difference between Mini Mac, Handymac, and Godwin Sub-Prime?
Mini Mac = compact submersible electric for vault/manhole/confined-space pump-down, 50-ft cable, drops in via crane hook. Handymac = portable surface self-priming pump, single-person carry, sits at grade with suction hose. Godwin Sub-Prime = engineered electric submersible series with 6 models from 0.5 HP to 2 HP, 1,100 GPM peak, more substantial than Mini Mac. Mini Mac and Handymac are the in-stock portables; Sub-Prime is the engineered Godwin counterpart for larger work.
Can dewatering pumps be used for permanent installations?
Generally no — dewatering pumps are designed for project-duration use (weeks to months), not multi-year permanent operation. For permanent industrial dewatering, mine drainage, or stormwater pumping installations, we route to Goulds Water Technology commercial pumps or Flygt industrial submersibles. Both offer Xylem-engineered solutions matched to permanent service life expectations. Email specs to sales@watermainsupply.com for engineered quote.
What's PrimeGuard 3 and do I need it?
PrimeGuard 3 is the Godwin microprocessor controller for unattended pump operation. Handles fuel transfer, pump start/stop logic, sequencing of multiple pumps, and remote monitoring via cellular or satellite to a central SCADA system. Required for: unattended overnight operation, remote sites without supervision, sewer bypass jobs requiring 24/7 monitoring, multi-pump installations with redundancy logic. Optional for: short-duration construction sites with daytime supervision and routine fuel checks.
Are you an authorized Xylem / Godwin dealer?
Yes — Watermain Supply (DBA of E4 Industrial LLC) is an authorized Xylem dealer with full portfolio access including Godwin (primary dewatering line), Goulds Water Technology, Flygt, Lowara, and Bell & Gossett. Houston-based with same-business-day quote response on engineered systems and same-day shipping on stocked portable dewatering pumps.
What's the lead time on Godwin equipment?
Stocked configurations of CD150, CD200, NC150, and Sub-Prime typically ship in 1-2 weeks from regional Xylem distribution. Custom-configured systems (DBS sewer bypass packages, Heidra HPU sets, wellpoint header systems) typically run 4-12 weeks depending on configuration and current factory backlog. For immediate need, Mini Mac and Handymac portables ship same-day from Houston stock — bridge for the 1-2 week wait on stocked Godwin or 4-12 week wait on engineered packages.
Do you handle Houston-specific applications like hurricane recovery and refinery turnaround?
Yes — we're Houston-based and routinely quote dewatering for hurricane flood recovery, refinery turnaround flood remediation, parking-garage emergency pump-down, and Gulf Coast construction projects. For emergency hurricane response, we maintain quick-turnaround inventory on portable dewatering and accelerate Xylem regional deployment for engineered packages.
