Every town in Gujarat that gets clean drinking water through a pipeline owes that to an engineer sitting somewhere in the Gujarat Water Supply and Sewerage Board. That's GWSSB, the body once called PHED (Public Health Engineering Department), and it still runs on the same role: a junior-level engineer who plans pipelines, checks pump houses, and signs off on water treatment work. In Gujarat's recruitment system, this post isn't called "Junior Engineer" on paper anymore. It's Additional Assistant Engineer, or AAE, a diploma-level Class III technical post recruited by GSSSB on behalf of GWSSB.
If you hold a diploma in Civil or Mechanical engineering and want a stable government job with a real technical role, this is one of the best options right now. Vacancy numbers have been big, the exam is diploma-level, not degree-level, and the competition, while heavy, is manageable if you prepare right. Here's everything you need.
Quick Answer
GWSSB/PHED Junior Engineer is officially recruited as "Additional Assistant Engineer (AAE), Class-3" through GSSSB. The Civil AAE drive (Advt 348/202526) had 974 posts after a vacancy increase, with its main written exam held on March 5, 2026 and result awaited. A separate Mechanical AAE drive had 110 posts, with applications closing June 29, 2026. A special Divyang-only Civil drive (Advt 402/202526) had its exam on July 8, 2026. As of August 2026, no fresh full-scale 2026-27 notification for new AAE Civil/Mechanical posts has opened yet — keep watching OJAS for the next cycle.
Latest Notification and Important Dates
Here's where things stand as of early August 2026. Three separate drives are running at different stages, so check which row applies to you.
| Event | Civil AAE (Advt 348/202526) | Mechanical AAE | Divyang Special Drive Civil (Advt 402/202526) |
|---|---|---|---|
| Notification released | May 2025 | June 2026 | 2026 |
| Vacancies | 974 (increased from 824) | 110 | Limited, Divyang category only |
| Application start | May 13, 2025 | June 15, 2026 | 2026 |
| Application end | August 18, 2025 (extended) | June 29, 2026 | 2026 |
| Written exam | March 5, 2026 | Tentative, likely August–September 2026 | July 8, 2026 |
| Answer key | March 7, 2026 (objections till March 13) | Not yet out | Not yet out |
| Result | Awaited | Awaited | Awaited |
A fresh AAE Civil/Mechanical notification hasn't come out yet as of this writing. If you missed both drives above, don't worry, GWSSB and GSSSB run this recruitment almost every year since water infrastructure work never stops in Gujarat. Check pareeksha.in's exam news section regularly so you catch the next one the day it drops.
What the Job Actually Is
An AAE posted under GWSSB works on water supply and sewerage infrastructure at the sub-division level, mostly in rural and semi-urban Gujarat. Daily work means supervising pipeline laying, checking material quality, measuring contractor work, preparing estimates, and maintaining pump houses and overhead tanks, reporting up to the Assistant Engineer. Mechanical AAEs handle pump machinery, motors, and electromechanical equipment at treatment plants. It's a field-heavy job early on, you'll be at construction sites more than behind a desk, and postings can land you in smaller towns, not just Ahmedabad or Gandhinagar.
Vacancy Details / Post Breakdown
The two disciplines run as separate drives, each with its own advertisement number.
| Discipline | Total Posts | Qualification Required |
|---|---|---|
| Additional Assistant Engineer (Civil) | 974 | Diploma in Civil Engineering |
| Additional Assistant Engineer (Mechanical) | 110 | Diploma in Mechanical or Automobile Engineering |
Reservation follows Gujarat government norms across SC, ST, SEBC, EWS, and women categories, with a carve-out for Divyang and ex-servicemen candidates, who sometimes get their own special drive, as with the July 2026 Civil exam.
Eligibility
Age limit: You need to be 18 to 33 years old as on the last date of application, with relaxation for reserved categories.
| Category | Age Relaxation | Effective Max Age |
|---|---|---|
| General/Unreserved Male | None | 33 years |
| General/Unreserved Female | +5 years | 38–40 years |
| SC/ST/SEBC/EWS Male | +5 years | 38 years |
| SC/ST/SEBC/EWS Female | +10 years | 43 years |
| Ex-Servicemen | +3 years (on top of category relaxation) | Varies |
| Persons with Disability | Extra relaxation applies, up to 45 years cap | 45 years |
Education: You need a Diploma in Civil Engineering (Civil post) or Diploma in Mechanical/Automobile Engineering (Mechanical post) from a recognised institution. Here's the catch many miss: B.E./B.Tech degree holders are NOT eligible, this is strictly a diploma-holder's job. You also need basic computer knowledge (CCC-equivalent) and working knowledge of Gujarati or Hindi. No strict domicile restriction applies, though local candidates find postings easier.
Application Process, Fee, and How to Apply
Applications go through the OJAS Gujarat portal only, no offline forms accepted.
| Category | Application Fee |
|---|---|
| General / Unreserved | ₹500 |
| SC / ST / SEBC / EWS / Women / PwD / Ex-Servicemen | ₹400 |
Steps to apply: Go to ojas.gujarat.gov.in and find the live GWSSB AAE advertisement. Register or log in with your existing OJAS profile. Fill in educational, personal, and category details carefully, errors here can get your form rejected later. Upload your scanned photo, signature, and diploma certificate as specified. Pay the fee online via net banking, card, or UPI. Save the confirmation page and application number, you'll need it to download your call letter.
Exam Pattern
This is a single-stage exam, unlike Talati or Class 1-2 posts which run prelims and mains. One written test decides your merit, followed by document verification.
| Part | Subject | Questions | Marks |
|---|---|---|---|
| Part A | Reasoning & Data Interpretation | 30 | 30 |
| Part A | Quantitative Aptitude | 30 | 30 |
| Part A | Constitution, Current Affairs & Comprehension | 30 | 30 |
| Part B | Technical (Civil or Mechanical Engineering) | 120 | 120 |
| Total | 210 | 210 |
Mode is CBRT/OMR-based MCQ, duration is 3 hours, and 0.25 mark is deducted per wrong answer. You need at least 40% in Part A and 40% in Part B separately, not just an overall average, so don't neglect either half.
Detailed Syllabus
Part A – Reasoning: analogy, coding-decoding, blood relations, seating arrangement, series completion, Venn diagrams, statement-conclusion, direction sense, and data interpretation from tables and graphs.
Part A – Quantitative Aptitude: number system, HCF-LCM, simplification, percentage, profit and loss, ratio, average, time and work, time-speed-distance, interest, basic algebra, and mensuration.
Part A – Constitution, Current Affairs & Comprehension: Preamble, fundamental rights and duties, directive principles, Parliament and state legislature, amendments, judiciary, Gujarat and national current affairs from the past year, and comprehension passages in Gujarati and English.
Part B – Civil Engineering: building materials and construction, surveying, strength of materials, structural analysis and basic RCC/steel design, geotechnical engineering, fluid mechanics and hydraulics, water supply and environmental engineering, transportation engineering, and estimating/costing.
Part B – Mechanical Engineering: engineering mechanics and strength of materials, thermodynamics and heat engines, fluid mechanics and hydraulic machines, theory of machines and basic design, manufacturing processes, industrial maintenance relevant to water infrastructure, and automobile engineering basics.
Start with the Quantitative Aptitude guide and Reasoning guide on Pareeksha for Part A, and the General Awareness guide for the Constitution and current affairs portion. For a daily current affairs habit, pareeksha.in/current-affairs works well.
Salary, Pay Scale, and Career Growth
The pay structure has two stages, and this trips people up if they don't read it carefully. For the first 5 years, you get a fixed monthly pay of ₹49,600, with no allowances added in most cases. After 5 years, on regularisation, you move to Pay Level-7 of the 7th Pay Commission, ₹39,900 to ₹1,26,600, plus DA, HRA, and other allowances, and take-home climbs well above the basic pay shown in the band.
Career growth: An AAE can be promoted over the years to Assistant Engineer, then Deputy Executive Engineer, and further up GWSSB's engineering cadre, depending on vacancies and departmental exams. It's a slower ladder than some government jobs, but a diploma holder starting here has a genuine long-term career in state engineering.
Previous Year Cut-off
Official cut-offs for the 2025-26 AAE Civil and Mechanical drives aren't out yet, results are still pending as of August 2026. Based on past AAE and similar Class III technical exams from GSSSB, expect the general category cut-off around 55-70% of 210 once declared. Treat that as a rough benchmark and aim for 65%+ overall to stay safe.
Best Books and Preparation Strategy
Don't try to relearn your whole 3-year diploma from scratch. In months 1-2, go through your diploma textbooks or a reference like Made Easy or ACE Academy handbooks, chapter by chapter, making short notes on formulas, not long theory. In month 3, solve previous GSSSB AAE, GPSC AE, and SSC JE papers, the syllabus overlaps a lot at diploma level, and this shows you what gets repeated. In month 4, split your day: mornings for technical revision, evenings for aptitude, reasoning, and current affairs. Don't let Part A slide just because you're an engineer, it's worth 90 marks and strong technical candidates often lose out there.
In the last 3-4 weeks, switch to full-length mock tests under timed conditions. Use pareeksha.in's free mock test series and topic-wise practice sets to simulate the real 210-question, 180-minute pressure. Build a fixed weekly routine with pareeksha.in's study plan tool instead of studying randomly.
Common Mistakes / Honest Advice
Don't apply for the wrong discipline just because the vacancy count looks bigger, Civil and Mechanical AAE have different technical papers and you can't switch your diploma qualification. Don't ignore Part A thinking you'll make it up in the technical section, the 40% cut applies separately to each part, so weak aptitude can sink a strong technical score. Don't wait till the last week to check OJAS, applications open and close faster than expected, and vacancy numbers can change mid-cycle like they did here (824 jumped to 974). And don't skip negative-marking math while practicing, blind guessing on 30-40 questions can cost your rank.
