Professional Underground Sump Cleaning
Underground Hygiene

1. Sump Cleaning

Underground sumps continuously receive unfiltered water from municipal supplies or borewells, leading to dense sludge, biological slime, and heavy sediment settle at the floor. Our intensive sump cleaning process restores pristine conditions safely and efficiently.

  • Removal of dirt and sludge using heavy-duty vacuum slurry extractors
  • Cleaning of sump walls and floor with rotary scrubbers and high-pressure jets
  • Complete removal of fine sediment, algae, and micro-contaminants
  • Hygienic cleaning process with non-toxic, food-grade antibacterial misting
  • Final inspection with water-level verification before refilling
Overhead Water Tank Sanitization
Overhead & Loft Storage

2. Water Tank Cleaning

Overhead Sintex, concrete, or stainless steel tanks are exposed to sunlight, temperature fluctuations, and airborne dust, producing algae colonies and insect contamination. Our mechanized procedure sanitizes tanks from top to bottom.

  • Comprehensive tank inspection for structural integrity and lid sealing
  • Dirt and sediment removal without wasting excess residual water
  • Tank interior cleaning with pressurized water nozzles and scrubbing tools
  • Washing and sanitization with safe disinfection solutions
  • Final inspection ensuring clear, odorless, and pure water output
Sump Waterproofing Treatment
Leakage Prevention

3. Sump Waterproofing

Groundwater infiltration or water loss through cracked sump masonry can compromise building foundations and contaminate drinking water with groundwater sewage. Our elastomeric and polymer coatings seal cracks permanently.

  • Detailed leakage inspection and pinpointing of moisture ingress points
  • Surface preparation including wire brushing and descaling of loose cement
  • Waterproofing treatment with multi-coat elastomeric protective polymer
  • Deep crack and seepage treatment using pressure grout/epoxy compound
  • Final inspection with water tightness curing warranty check

Main-line sand filters, activated carbon units, sediment filter candles, and RO pre-filtration systems choke quickly from high TDS and suspended particles. We provide on-site tune-ups, cartridge flushes, and filter re-bedding.

  • Filter inspection including inlet/outlet pressure differential testing
  • Cleaning and service of housings, strainers, and backwash valves
  • Filter component checking: membranes, O-rings, and pressure switches
  • Performance check to ensure optimal flow rate and turbidity reduction
