Some of the best management practices for municipalities have been completed into a reasonable, rational and logical program by PWNA (Power Washers of North America) and UAMCC (United Association of Mobile Contract Cleaners).

This was in the form of an EPA’s Model Ordinance best management program for Cosmetic Cleaning. Cosmetic cleaning guidelines are for regular maintenance and do not include hazardous waste.

First to always pre-clean, best management practices is not to discharge into sanitary sewers or storm drains but to clean up debris, oil and grease spots properly and appropriately. Second, always filter waste water, remove silt, sand, sludge and debris with a mesh screen and remove hydrocarbons through a clarifier. Also collecting the waste and handing it over to an environmental waste company.

Discharges to a sanitary sewer are only allowed after and with a cosmetic cleaning permit keeping in mind the local regulations and limits. Keep in mind; never discharge detergents, chemicals, visible foam, oil sheen or cold water to storm drains as they might overflow. As for discharging to a landscaped area, the best practices dictate there should be proper permission and the volume of waste should be able to soak in the ground. The best practices to keep in mind to switch areas to prevent soil and water contamination, environmental damage and other nuisance conditions.

Equipment of HYDRO TEK used for these best practices have been trusted for over two decades. This heavy duty pressure washer equipment used everyday, with rugged frames and rust proof stainless steel enclosures, is sold exclusively and supported by a network of distributors.

Sanitary sewer can be kept away from sand, grit, and grease trap by oil or water separator, kitchen sink or simply even a mop. The best management practices when satisfactory discharge limits are not reached with continuous waste water flow is to use holding tanks to bring the level to acceptable limits. Use biodegradable and non-phosphate detergents or non-toxic chemicals if possible so that they can be processed easily.

The best management practices to capture waste. Use a portable dams and drain covers or permanent containment pad or seal the storm drains. Also all recycled waste water discharge locations are reported to sanitary sewer department in advance. The drought conditions, potable/drinking water can not be used for power washing for health and safety reasons, grey water can be used and trucked-in portable water is acceptable; but all need permission in advance from the Health or Environmental department.

MOSMATIC surface cleaners products are also available. The roof cleaner is safe and easy to use with height and weight adjustment. The commercial surface cleaner is an efficient maintenance free industrial cleaner. The economy surface cleaner is made light and easy to use for vertical and horizontal surfaces.

The best management practices result from prior experiences of the methodologies and techniques that are improved over time, making them more efficient and effective. By implementation of such management practices, one can certainly hope for better cleaning results.
