Water Tank Installation

Construction Sewa installs water storage tanks for homes, apartments, hotels, schools, and commercial buildings all over Nepal. We size the tank to what you'll actually use, build a base strong enough to carry it at full weight not empty and connect every pipe, inlet, outlet, overflow, drain, before testing the whole system and handing it over.

Our Working Process

1.      Consultation: we discuss your water usage, building type, and whether you need a new tank or a replacement

3.      Water Requirement Assessment: we calculate daily usage based on household size or occupancy

4.      Tank Capacity & Location Planning: recommending the right size and placement for your property

5.      Base Preparation: a stand or base built to safely carry the tank's full weight when filled

6.      Tank Placement: the tank is positioned and secured on the prepared base or stand

Need the float valve or pump serviced down the line? Our Tap & Valve Replacement and Water Motor Installation teams handle that separately as well.

Materials & Options

•       Plastic (HDPE/LLDPE): lightweight, low-maintenance, and UV-resistant; a common choice for homes and rooftops

•       Stainless Steel: corrosion-resistant and hygienic, holding up for decades; suited to hotels, hospitals, and homes prioritizing water quality

•       RCC (Concrete): built for large storage capacity and permanent installation; needs periodic waterproofing checks

•       Underground Tanks: suited where roof space or structural load is limited; usually paired with a pump

We'll help you weigh these against your building type, roof load, and budget right there at the site visit. Going with an RCC tank? Our Terrace Waterproofing service keeps it sealed against leaks for years after.

Frequently Asked Questions

Which type of water tank is best for homes?

Plastic (HDPE) tanks are the go-to for most homes lightweight, affordable, and they don't ask much of you in terms of upkeep. Stainless steel's the stronger alternative if hygiene and long-term durability matter more to you than upfront cost.

Should I install an overhead or underground water tank?

Overhead tanks use gravity for pressure and are easier to get to when something needs checking. Underground makes sense when roof space or structural load won't allow for a rooftop tank. We'll help you decide once we've actually seen the property.

What size water tank do I need?

Comes down to family size or occupancy, and how much water gets used day to day. We work that out during the site visit and water requirement assessment we don't guess at it.

Can you replace an old water tank?

Yes. Full replacement, including pulling out the old tank, checking whether the base still holds up, and reconnecting the plumbing to the new one.

Do you install the plumbing connections as well?

Yes. Inlet, outlet, overflow, drain the whole plumbing connection is part of the installation, not something we leave for someone else to sort out.
