# Mound Septic System Service in Colorado A mound system builds the drain field above natural grade when there is not enough usable soil below it. They are common on shallow bedrock, high groundwater, and tight clay sites across the Front Range and foothills. - Pumping and dosing service for mound systems - Seepage and side slope diagnosis - Care guidance so the mound is not damaged ## What mound system means **Mound system.** A mound system is an engineered drain field built in a raised bed of sand and gravel above the natural ground, dosed by a pump. It is used where the soil is shallow, slow, or too close to bedrock or groundwater. A mound is a pressurized, mechanical system, so pump care and even dosing matter far more than on a gravity field. ## Why mounds exist and how they fail When the separation between the bottom of a trench and bedrock or groundwater is too small, a county will not permit a conventional field. A mound solves that by placing sand fill and a pressurized distribution bed above grade, creating the treatment depth the site does not have naturally. Mounds fail from overloading, from a dosing pump that stops dosing evenly, and from physical damage. Driving on a mound, planting trees in it, or letting downspouts run at its toe will all shorten its life. Seepage at the toe of the mound is the classic warning sign. ## How we service a mound system 1. **Pump the tank and check the filter.** Solids reaching a pressurized bed plug orifices fast, so the tank comes first every time. 2. **Test the dose cycle.** Pump, floats, and timer are verified so every lateral gets its share of each dose. 3. **Walk the mound.** We look for seepage at the toe, erosion, settlement, and traffic damage on the slopes. 4. **Report and plan.** You get a plain description of what is working, what is marginal, and what needs attention this year. ## Why call us for a mound - We understand pressurized distribution, not just gravity systems - Careful access so heavy equipment never crosses the mound - Honest read on seepage before it becomes a county issue - Serving foothills and rural Front Range properties ## What drives mound system cost Tank size and pumping volume, dosing pump and control parts, orifice cleaning or lateral repairs, and the extent of any fill, erosion, or seepage correction needed on the mound itself. ## Mound system questions ### Can I plant on my mound? Grass only. Shallow rooted turf holds the slopes together. Trees and shrubs damage the bed and the laterals. ### Why is water seeping from the side of my mound? Usually overloading or uneven dosing. It can also mean the bed is aging. Either way it needs to be evaluated promptly. ### Do mounds need more maintenance than conventional systems? Yes. There is a pump and pressurized distribution, so there is more to check and more reason to keep the tank pumped on schedule. ## Related services - [Septic Tank Pumping](https://www.affordablesepticpumping.com/septic-tank-pumping-denver): Scheduled and same-day pump-outs for Denver and Front Range properties. - [Septic System Repair](https://www.affordablesepticpumping.com/septic-system-repair-denver): Baffles, lines, lids, pumps, and drain field repairs across the Front Range. - [Septic System Installation](https://www.affordablesepticpumping.com/septic-system-installation-denver): Tank and drain field installation and replacement, permit to final inspection. --- Source page: https://www.affordablesepticpumping.com/mound-system Affordable Septic Pumping, 8996 Pierce St, Westminster, CO 80021.
