Buying or building on a plot in Varachha? Read its kundli first: earthquake zone and foundation, groundwater, water quality, rain and the harvesting rule, Vastu for its facing, and the cost of the house.

Zone IIIearthquake zone, IS 1893
Plot Kundli: 200 gaj, north-facing, Varachha, Surat
Varachha, Surat is in seismic zone III: moderate damage risk.
Design the frame to IS 1893 and use the ductile detailing of IS 13920 for buildings of more than two floors, and always where there is stilt parking.
For a G+1 house, isolated RCC footings are the usual starting point on firm soil; filled ground, black cotton soil or a high water table call for a raft or piles. A soil test (about ₹15,000 to ₹40,000) settles it before the drawings.

Jal Groundwater level and borewell
Favourable
Groundwater is in a safe state here.
Surat district pumps out 42% of the groundwater it can safely take each year (CGWB 2025), which CGWB rates safe.
That is up from 27% in 2017.
Before the monsoon, the water stood 3 to 29 m below ground in CGWB's 50 monitoring wells (2018); most read 5–10 m. 2% were deeper than 20 m, out of reach of shallow borewells.
A borewell is workable, but recharge the roof water so it stays that way as the area builds up.

Neer Groundwater quality
Needs care
CGWB found fluoride above the safe limit in some of Surat district's groundwater.
Test the borewell water on your plot (TDS, fluoride, nitrate and hardness) before you rely on it, and budget an RO or a fluoride filter for drinking water.
4
Varsha Rain, rainwater harvesting and recharge
Needs care
Check the rainwater harvesting rule with your local authority.
Gujarat Development Control Regulations (GDCR); all new state government buildings since 2003 names group housing, commercial, public buildings, government; it does not clearly cover a house. Ask your municipal body before you build.
Varachha, Surat gets about 1,669 mm of rain a year (NASA POWER, 2006 to 2025), 94% of it from June to September. A 1,170 sq ft roof can send about 1,54,202 litres a year back into the ground.
That needs one recharge pit with a 60 ft recharge bore, costing about ₹87,000 to ₹1.4 lakh with GST.
By Vastu, underground water belongs in the north-east, which is where the recharge pit or sump usually goes.
5
Vastu Facing and layout
Favourable
North-facing plot. North-facing plots are among the most sought after in Vastu, linked with wealth and growth.
Main door: in the middle-to-east part of the north wall (padas N3 to N5).
Kitchen in the south-east (or north-west), cooking facing east. Master bedroom in the south-west. Pooja room in the north-east.
Stairs in the south, west or south-west, climbing clockwise. Toilets in the west or north-west, never in the north-east or the centre.
Overhead tank over the south-west; borewell, sump and recharge pit in the north-east; septic tank in the north-west. Keep the centre of the house (brahmasthan) open and uncluttered.
6
Nirman Construction cost and approvals
Favourable
About ₹56 lakh to ₹62 lakh for a G+1 house of 2,340 sq ft, finished to a standard specification.
Taken at 65% ground coverage: 1,170 sq ft a floor on a 1,800 sq ft (200 gaj) plot. Your local bye-laws set the real coverage, setbacks and height for the plot size.
Structure only: ₹40 lakh to ₹44 lakh. Premium finishes: ₹70 lakh to ₹82 lakh and up. Rates are per sq ft of built-up area with GST, from our own priced BOQ.
Not included: approval fees, a basement, boundary wall, lift, solar, borewell and interiors.
Before work starts: building plan approval with architectural and structural drawings, then the occupation certificate at the end, which in most states needs the rainwater harvesting pits built.
Groundwater, water quality and rain figures are for Surat district as a whole: the government does not publish them by sector or locality. Vastu notes are traditional guidance, and the foundation and cost lines are starting points. A site visit, a soil test and a water test on your plot give the exact picture.

Which earthquake zone is Varachha, Surat in?
Seismic zone III under IS 1893 (Part 1): 2016. Design the frame to IS 1893 and avoid an open, unbraced stilt floor.
Is rainwater harvesting mandatory for a house in Varachha, Surat?
Mandatory for plots of 500 sq m and above (older GDCR); Surat: high-rise or plots over 4,000 sq m. That needs one recharge pit with a 60 ft recharge bore, costing about ₹87,000 to ₹1.4 lakh with GST.

What is a Plot Kundli?
A free report on a plot before you buy or build on it, read in six houses like a kundli: Bhoomi (ground, earthquake zone and foundation), Jal (groundwater), Neer (water quality), Varsha (rain and rainwater harvesting), Vastu (facing and layout) and Nirman (cost and approvals). It is built from CGWB, NASA POWER and BIS figures and the state's building rules.
