The biggest permit question for a car wash is its dirty water. Facilities that discharge regulated effluents file for a discharge permit with DENR through EMB, and some cities go further: Baguio withholds the business permit until a car wash installs a treatment facility such as a septic tank. This sample plan puts drainage first, fills in DTI and BIR fees and leaves prices and car counts blank.[3,4]
Summary
Example: [Car wash name] will wash cars, SUVs and motorcycles at a [lot size] lot on [road], [city], with [number] wash bays and a waiting shed. Services: basic wash, wash and vacuum, interior cleaning, engine wash, wax. Owner: [name], sole proprietor.
Capital: ₱____ for pressure washers, vacuum, water tank, drainage and treatment, roofing and signage. Owner ₱____; loan ₱____. The plan treats wastewater handling as a start-up cost, not an afterthought.
Site, water and drainage
Pick a lot with easy entry and exit from a road with traffic you can count. Then check drainage before anything else: where will soapy, oily water go?
Under DENR DAO 2004-25, owners or operators of facilities that discharge regulated effluents must file for a discharge permit issued by DENR through EMB. Ask the EMB regional office whether your car wash's water counts and what the application needs.[3]
Local rules can add more. A Baguio City ordinance requires car wash owners to build or install a treatment facility such as a septic tank, and non-compliance means the business permit is not issued. Ask your city hall whether it has a similar ordinance before you design the bays.[4]
Customers and competition
Fill in: Vehicles passing the lot between [times]: [number], counted on [three days including a Saturday]. Nearby sources of customers: [subdivision, offices, TNVS drivers, motorcycle riders]. We asked [number] drivers how often they wash and where.
Competitors: [number] car washes within [distance]; for each, services, price of a basic wash by our visit on [date], hours and queue on weekends. Our angle: [faster line, motorcycle bay, waiting area with wifi, monthly wash card].
Daily operations
Staff. [Number] washers per shift, one cashier or the owner. Pay: [daily rate ₱____ or share of ____% per car]. Register as an employer if you hire.
Supplies. Shampoo, wax, tyre black, microfiber cloths, from [supplier] every [period]. Track use per car to control cost.
Waste. Bacolod's environment office lists garbage storage and bins with proper segregation among a car wash's requirements. Plan where used cloths, bottles and sludge from the treatment facility will go.[5]
Registration and permits
Beyond the usual steps, budget for the DENR discharge permit and any treatment facility your city requires. Those amounts were not published in our sources, so collect a quote from a contractor and ask EMB about the permit.[3]
Financial plan

Lot lease deposit ₱____; pressure washers [number] × ₱____; vacuum ₱____; water tank and pump ₱____; drainage, oil trap and treatment facility ₱____; roofing ₱____; signage ₱____; first supplies ₱____; segregation bins ₱____; DTI name ₱200 or ₱500 plus ₱30 stamp tax; barangay clearance ₱____; mayor's permit ₱____; discharge permit ₱____; reserve ₱____.[1]

- What should I ask the city before leasing a lot for a car wash?
