• Pre-Planned Maintenance

    Prevent your drains from any future performance lapse with pre-planned maintenance aimed at stopping drainage problems before they become problems.

​Drain Maintenance Services & PPM

Your property is unique and often has complex drainage requirements, dependent on the use and sector your property is in. We are able to tailor our pre-planned maintenance (PPM) service to support all your internal and external drains.
Drain Maintenance
A PPM agreement will help to prevent drainage emergencies from occurring. Many of our customers already benefit from routine Pre-Planned Maintenance (PPM), with each and every maintenance plan being bespoke to your needs and industry. We strategically plan scheduled visits to prevent loss of revenue or general inconvenience to your working day or night dependent on your needs. General PPM agreements will include a CCTV site survey, with any issues highlighted. We will then provide cleaning and flush through the drainage systems, ensure they are running free of any fat, oil, grease, scale, debris and obstructions that may cause concern or blockages in the future. 

From here a dedicated service agreement plan or maintenance programme will be proposed bespoke to your requirements.

Periodic Maintenance Contracts 

We will be out on schedule, on task, so you don't need to worry. Worksheets and reports are efficiently submitted, ensuring compliance with SLA's, site, H&S, client and drain maintenance contract requirements. 

Efficient Planning

We plan and schedule our works and routes efficiently, keeping our costs down and services at their best. Need a service or new agreement at short notice? Our team are on hand to support you.

Total Drainage Solutions

We carry out full drainage services, meaning when we conduct our drain maintenance visit, we can survey, log, unblock, clean, repair and report on our findings. 

Issue Tracking

With our reporting service, you can track troublesome drains. If we continue to find recurring issues with the same drainage system we are maintaining, we can then consult with you to investigate the issue further, cutting down on costs and risk of damage further back up the drainage system.

What are the benefits of a PPM agreement?

  • Agreements are created bespoke to your company needs
  • Strategically planned visits to prevent loss of revenue
  • Prevent emergency situations
  • Protect your property from damage
  • Cost effective

The Grey-Water team, reliably attend pre-planned maintenance programmes to help prevent those emergency situations. Keeping up with the maintenance of your drains will minimize emergencies, as problems will be detected before they become an issue and cause disruption, costly repairs, and damage.

            Frequently Asked Questions

            When should I undertake pre-planned maintenance?

            There is no wrong time to undertake pre-planned maintenance. The idea of this service is to prevent problems before they occur, so if your drain system is currently not experiencing issues, now may be the best time to call Grey-Water Drainage, as this doesn't mean there isn't the potential for blockages with the beginning of debris build-up that could be solved with jetting, or small fractures that could benefit from a CCTV survey to ascertain any weak points.

            How long does pre-planned maintenance take?

            PPM can vary in length depending on several factors including the complexity of the project, the size of the drain system, how accessible the drain is, what site and weather conditions are like. With these variables, it is difficult to determine an exact timeframe but upon assessing your particular drain system, we should be able to give a more accurate scale for PPM.

            How much does pre-planned maintenance cost?

            Our PPM fees depend on the size of your drainage system and how long it takes to assess. Our rates generally start at £350.

            Do I have to pay in advance for pre-planned maintenance?

            Due to previous experiences, we ask for payment in advance of PPM.

            Do I need pre-planned maintenance?

            In the long-run, PPM is the safest bet when considering the health of your drainage system. Without it, your drains could fall foul of higher damage and higher repair costs as a result of not having been protected from the get-go.

            Is there a local pre-planned maintenance service near me?

            If you live in the Kent or London area, we have local operatives in your area who are able to carry out pre-planned maintenance and repair. Give us a call and we will provide you with our next available visit date.
